Ngo has experimented with piracetam himself (“The first time I tried it, I thought, ‘Wow, this is pretty strong for a supplement.’ I had a little bit of reflux, heartburn, but in general it was a cognitive enhancer. . . . I found it helpful”) and the neurotransmitter DMEA (“You have an idea, it helps you finish the thought. It’s for when people have difficulty finishing that last connection in the brain”).

If you are looking for a way to maximize brain power I have come across a great product named Brain Abundance. Here are a list of the ingridients, folic acid, grape seed extract, L-Glutamine, phenylalanine, sensoril, rhodiola, vitamin b-12, astaxanthin, niacinamide, zinc picolinate, resveratrol, vitamin b-6, ginseng. I have personally taken this product and have had great results with the following: cognitive function, healthy memory, stress and anxiety, positive mood and mind, better sleep, focus and mental clarity, and much more. Feel free to find out more information at:
the larger size of the community enables economies of scale and increases the peak sophistication possible. In a small nootropics community, there is likely to be no one knowledgeable about statistics/experimentation/biochemistry/neuroscience/whatever-you-need-for-a-particular-discussion, and the available funds increase: consider /r/Nootropics’s testing program, which is doable only because it’s a large lucrative community to sell to so the sellers are willing to donate funds for independent lab tests/Certificates of Analysis (COAs) to be done. If there were 1000 readers rather than 23,295, how could this ever happen short of one of those 1000 readers being very altruistic?
Not that everyone likes to talk about using the drugs. People don’t necessarily want to reveal how they get their edge and there is stigma around people trying to become smarter than their biology dictates, says Lawler. Another factor is undoubtedly the risks associated with ingesting substances bought on the internet and the confusing legal statuses of some. Phenylpiracetam, for example, is a prescription drug in Russia. It isn’t illegal to buy in the US, but the man-made chemical exists in a no man’s land where it is neither approved nor outlawed for human consumption, notes Lawler.
Forums including have more than 140,000 subscribers discussing products with names like Orange Brainwash and GodMode. Nootropics are blends of ingredients touted as a low-risk way to enhance learning, memory, motivation, and even serenity. These ingredients range from herbs such as water hyssop (Bacopa monnieri) and arctic root to chemicals such as vinpocetine.
The hormone testosterone (; FDA adverse events) needs no introduction. This is one of the scariest substances I have considered using: it affects so many bodily systems in so many ways that it seems almost impossible to come up with a net summary, either positive or negative. With testosterone, the problem is not the usual nootropics problem that that there is a lack of human research, the problem is that the summary constitutes a textbook - or two. That said, the 2011 review The role of testosterone in social interaction (excerpts) gives me the impression that testosterone does indeed play into risk-taking, motivation, and social status-seeking; some useful links and a representative anecdote:
We hope you find our website to be a reliable and valuable resource in your search for the most effective brain enhancing supplements. In addition to product reviews, you will find information about how nootropics work to stimulate memory, focus, and increase concentration, as well as tips and techniques to help you experience the greatest benefit for your efforts.
Finally, it’s not clear that caffeine results in performance gains after long-term use; homeostasis/tolerance is a concern for all stimulants, but especially for caffeine. It is plausible that all caffeine consumption does for the long-term chronic user is restore performance to baseline. (Imagine someone waking up and drinking coffee, and their performance improves - well, so would the performance of a non-addict who is also slowly waking up!) See for example, James & Rogers 2005, Sigmon et al 2009, and Rogers et al 2010. A cross-section of thousands of participants in the Cambridge brain-training study found caffeine intake showed negligible effect sizes for mean and component scores (participants were not told to use caffeine, but the training was recreational & difficult, so one expects some difference).
Some nootropics users are hopeful that the drugs could be permanently “neuroprotective”—in other words, that the compounds could slow down the neuronal aging process, and help avoid cognitive deterioration later in life. (For what it's worth, most of the users I spoke to said that didn't matter much to them. “I doubt anything I’ve tried has made me smarter in a long-term way,” Baker says. “That’s still science fiction.”)
With so many different ones to choose from, choosing the best nootropics for you can be overwhelming at times. As usual, a decision this important will require research. Study up on the top nootropics which catch your eye the most. The nootropics you take will depend on what you want the enhancement for. The ingredients within each nootropic determine its specific function. For example, some nootropics contain ginkgo biloba, which can help memory, thinking speed, and increase attention span. Check the nootropic ingredients as you determine what end results you want to see.

For example, prenatal exposure to pthalates, which are chemical compounds that are commonly added to plastics to increase their durability and flexibility, have been linked tobehavioural abnormalities characterised by shortened attention span and impaired social interaction. Pthalates are an extensive group of chemicals, and whilst not all of them have been studied, several have shown to have negative health impacts. This class of chemicals is found abundantly and can find they can find their way into food packaging, cosmetics and household cleaners - making them virtually impossible to avoid. However, a growing awareness about the potential negative impact on health has led to the production of pthalate-free cosmetic and personal care products, as well as cleaning products. It may, therefore, be a significant step to try to avoid these chemicals by choosing products wisely, as well as trying to buy vegetables, fruit etc that haven’t been wrapped in plastic.

By which I mean that simple potassium is probably the most positively mind altering supplement I’ve ever tried…About 15 minutes after consumption, it manifests as a kind of pressure in the head or temples or eyes, a clearing up of brain fog, increased focus, and the kind of energy that is not jittery but the kind that makes you feel like exercising would be the reasonable and prudent thing to do. I have done no tests, but feel smarter from this in a way that seems much stronger than piracetam or any of the conventional weak nootropics. It is not just me – I have been introducing this around my inner social circle and I’m at 7/10 people felt immediately noticeable effects. The 3 that didn’t notice much were vegetarians and less likely to have been deficient. Now that I’m not deficient, it is of course not noticeable as mind altering, but still serves to be energizing, particularly for sustained mental energy as the night goes on…Potassium chloride initially, but since bought some potassium gluconate pills… research indicates you don’t want to consume large amounts of chloride (just moderate amounts).

Powders are good for experimenting with (easy to vary doses and mix), but not so good for regular taking. I use OO gel capsules with a Capsule Machine: it’s hard to beat $20, it works, it’s not that messy after practice, and it’s not too bad to do 100 pills. However, I once did 3kg of piracetam + my other powders, and doing that nearly burned me out on ever using capsules again. If you’re going to do that much, something more automated is a serious question! (What actually wound up infuriating me the most was when capsules would stick in either the bottom or top try - requiring you to very gingerly pull and twist them out, lest the two halves slip and spill powder - or when the two halves wouldn’t lock and you had to join them by hand. In contrast: loading the gel caps could be done automatically without looking, after some experience.)

Your memory may decline with age and high-stress lifestyle. In this post, we cover supplements and nootropics that help improve memory, with the mechanisms. If you’re interested in cognitive enhancement that my clients and I have used for awesome results you should check out our book, SelfHacked Secrets. To receive the first chapter free click here.
Before taking any supplement or chemical, people want to know if there will be long term effects or consequences, When Dr. Corneliu Giurgea first authored the term “nootropics” in 1972, he also outlined the characteristics that define nootropics. Besides the ability to benefit memory and support the cognitive processes, Dr. Giurgea believed that nootropics should be safe and non-toxic.

I split the 2 pills into 4 doses for each hour from midnight to 4 AM. 3D driver issues in Debian unstable prevented me from using Brain Workshop, so I don’t have any DNB scores to compare with the armodafinil DNB scores. I had the subjective impression that I was worse off with the Modalert, although I still managed to get a fair bit done so the deficits couldn’t’ve been too bad. The apathy during the morning felt worse than armodafinil, but that could have been caused by or exacerbated by an unexpected and very stressful 2 hour drive through rush hour and multiple accidents; the quick hour-long nap at 10 AM was half-waking half-light-sleep according to the Zeo, but seemed to help a bit. As before, I began to feel better in the afternoon and by evening felt normal, doing my usual reading. That night, the Zeo recorded my sleep as lasting ~9:40, when it was usually more like 8:40-9:00 (although I am not sure that this was due to the modafinil inasmuch as once a week or so I tend to sleep in that long, as I did a few days later without any influence from the modafinil); assuming the worse, the nap and extra sleep cost me 2 hours for a net profit of ~7 hours. While it’s not clear how modafinil affects recovery sleep (see the footnote in the essay), it’s still interesting to ponder the benefits of merely being able to delay sleep19.

Adaptogens are also known to participate in regulating homeostasis through helping to beneficially regulate the mechanisms of action associated with the HPA-axis (think back to the importance of proper HPA-axis function which you learned about in my last article on breathwork), including cortisol regulation and nitric oxide regulation. Through these mechanisms, they can protect against chronic inflammation, atherosclerosis, neurodegenerative cognitive impairment, metabolic disorders, cancer and other aging-related diseases. There are plenty of adaptogens with potent benefits, but the ones you learn about in this article are an excellent start to begin building or expanding your stress-adaptation toolbox.

The human drive to be smarter is a familiar theme on the big screen. In 2011, Oscar-nominated actor Bradley Cooper played struggling writer Eddie Morra in the sci-fi thriller Limitless. In the film, Morra acquires a (fictitious) nootropic NZT-48 that allows him to access 100 percent of his mind. Although he finds himself in lots of trouble, his use of the nootropic transforms him from a desperate writer to a multimillionaire who ultimately runs for the U.S. Senate. The film is a testament to a dream deeply entrenched in the American psyche – that an everyman can become superhuman and lead an extraordinary life.
The fish oil can be considered a free sunk cost: I would take it in the absence of an experiment. The empty pill capsules could be used for something else, so we’ll put the 500 at $5. Filling 500 capsules with fish and olive oil will be messy and take an hour. Taking them regularly can be added to my habitual morning routine for vitamin D and the lithium experiment, so that is close to free but we’ll call it an hour over the 250 days. Recording mood/productivity is also free a sunk cost as it’s necessary for the other experiments; but recording dual n-back scores is more expensive: each round is ~2 minutes and one wants >=5, so each block will cost >10 minutes, so 18 tests will be >180 minutes or >3 hours. So >5 hours. Total: 5 + (>5 \times 7.25) = >41.
A new all-in-one nootropic mix/company run by some people active on /r/nootropics; they offered me a month’s supply for free to try & review for them. At ~$100 a month (it depends on how many months one buys), it is not cheap (John Backus estimates one could buy the raw ingredients for $25/month) but it provides convenience & is aimed at people uninterested in spending a great deal of time reviewing research papers & anecdotes or capping their own pills (ie. people with lives) and it’s unlikely I could spare the money to subscribe if TruBrain worked well for me - but certainly there was no harm in trying it out.

People with failing memory and worried about Alzheimer’s disease are sometimes seduced by advertisements for Huperzine A, extracted from a type of moss. Some studies have shown that it increases levels of acetylcholine in the brain, a chemical that is in short supply in Alzheimer’s. But despite increasing acetylcholine, aside from a few questionable studies in China, there is no evidence that it improves memory. Unfortunately when it comes to memory pills, they are best forgotten. There is, however, hope that a nasal spray containing insulin can increase the absorption of glucose into brain cells and improve cognitive function. But in the meantime, the best bet to maintain good brain function is to monitor blood glucose and blood pressure, eat a diet rich in fruits, vegetables and whole grains, and low in simple carbs and saturated fat. And don’t forget that physical exercise also exercises your brain.

Walnuts in particular are excellent brain food. These wrinkly nuts—which kind of resemble the human brain—are rich in vitamin E. Researchers at Chicago’s Rush University Medical Center studied the lifestyle habits of 6,000 people who were unaffected by Alzheimer’s the memory-robbing condition, and found that those who ate the most vitamin E-rich foods had a reduced risk of developing the memory-robbing condition. Vitamin E may trap free radicals that can damage brain cells, according to the Alzheimer’s Research Center. Here’s some more brain food that your noggin will thank you for eating.

After 7 days, I ordered a kg of choline bitartrate from Bulk Powders. Choline is standard among piracetam-users because it is pretty universally supported by anecdotes about piracetam headaches, has support in rat/mice experiments28, and also some human-related research. So I figured I couldn’t fairly test piracetam without some regular choline - the eggs might not be enough, might be the wrong kind, etc. It has a quite distinctly fishy smell, but the actual taste is more citrus-y, and it seems to neutralize the piracetam taste in tea (which makes things much easier for me).

Clinical psychiatrist Emily Deans has a private practice in Massachusetts and teaches at Harvard Medical School. She told me by phone that, in principle, there's "probably nothing dangerous" about the occasional course of nootropics for a hunting trip, finals week, or some big project. Beyond that, she suggests considering that it's possible to build up a tolerance to many neuroactive products if you use them often enough.
Phillips told me that, much as he believes in neuroenhancers, he did not want to be "the poster boy for smart-in-a-pill". At one point, he said: "We really don't know the possible implications for long-term use of these things." (He recently stopped taking Provigil every day, replacing it with another prescription stimulant.) Nor does he think we need to be turning up the crank another notch on how hard we work. "But," he said, "the baseline competitive level is going to reorientate around what these drugs make possible, and you can choose to compete or not."

You would have heard this advice from top achievers in any field, “Work Smarter, not Harder.” Then why not extend the same philosophy in all areas of your life? Are you smarting from a situation wherein no matter how much you exercise, eat healthy, and sleep well, you still find it a struggle to focus and motivate yourself? If yes, you need smart help that is not hard on you. Try ‘Smart Drugs’, that could help you come out of your situation, by speeding up your thought process, boosting your memory, and making you more creative and productive.
I do recommend a few things, like modafinil or melatonin, to many adults, albeit with misgivings about any attempt to generalize like that. (It’s also often a good idea to get powders, see the appendix.) Some of those people are helped; some have told me that they tried and the suggestion did little or nothing. I view nootropics as akin to a biological lottery; one good discovery pays for all. I forge on in the hopes of further striking gold in my particular biology. Your mileage will vary. All you have to do, all you can do is to just try it. Most of my experiences were in my 20s as a right-handed 5’11 white male weighing 190-220lbs, fitness varying over time from not-so-fit to fairly fit. In rough order of personal effectiveness weighted by costs+side-effects, I rank them as follows:

Any consideration of the future of nootropics is directly tied into the future of humanity. As long as work productivity demands continue to soar, there will like be a affiliated rise in the desire to increase brain power. As Vice discusses in a thoughtful article providing several insights into why nootropics are popular, it is not surprising that smart drugs and the nootropic industry are ever-expanding. Vice points out that sci-fi writers once warned of people being overtaken by machines, but instead, human beings are becoming machines, taking on unrealistic work levels.[15] Taking nootropic drugs is akin to loading up on premium fuel in an effort to go faster and do better.
If you are a slow caffeine metabolizer and consume too much caffeine, you run the risk of mild to severe complications, such as cardiovascular disease. There’s also the sleep disruption problem of having too much caffeine left in your bloodstream late in the day as a result of a longer caffeine half-life, a problem not faced by fast caffeine metabolizers (it’s so unfair if you love your cup of joe, right?). In addition, fast caffeine metabolizers actually run a reduced risk of cardiovascular complications if they consume at least one cup of coffee per day. While anyone can be a slow caffeine metabolizer, there are certain ethnic backgrounds that are indeed associated with slower and faster caffeine metabolisms. For example, it’s known that people with Asian and African ethnic backgrounds generally have slower rates of caffeine metabolism. To find out if you’re a fast or slow caffeine metabolizer, you can have a relatively inexpensive salivary genetic test performed by a company like 23andme and then use the online dashboard to jump straight to your CYP1A2 gene. When you’re there, you type into the search bar “rs762551”. If your rs762551 SNP variant is AA, then you’re a fast caffeine metabolizer, but if your variant is AC or CC, you’re a slow caffeine metabolizer. Fortunately, many genetic testing companies will now simply report directly on your results whether you’re a slow or fast metabolizer, without you needing to go through the SNP searching trouble.
One thing I notice looking at the data is that the red magnesium-free days seem to dominate the upper ranks towards the end, and blues appear mostly at the bottom, although this is a little hard to see because good days in general start to become sparse towards the end. Now, why would days start to be worse towards the end, and magnesium-dose days in particular? The grim surmise is: an accumulating overdose - no immediate acute effect, but the magnesium builds up, dragging down all days, but especially magnesium-dose days. The generally recognized symptoms of hypermagnesemia don’t include effect on mood or cognition, aside from muscle weakness, confusion, and decreased reflexes…poor appetite that does not improve, but it seems plausible that below medically-recognizable levels of distress like hypermagnesemia might still cause mental changes, and I wouldn’t expect any psychological research to have been done on this topic.
Because smart drugs like modafinil, nicotine, and Adderall come with drawbacks, I developed my own line of nootropics, including Forbose and SmartMode, that’s safe, widely available, and doesn’t require a prescription. Forskolin, found in Forbose, has been a part of Indian Ayurvedic medicine for thousands of years. In addition to being fun to say, forskolin increases cyclic adenosine monophosphate (cAMP), a molecule essential to learning and memory formation. [8]
This supplement is dangerous and should not be sold. I have taken brain supplements for a while and each of them are very similar, EXCEPT for Addium. On the day I took Addium many blood vessels in my hands burst, and two on my face burst. With their "proprietary blend" not being detailed as to the amount of each ingredient (only listed in the aggregate of 500mg Proprietary Blend) you have no way of determining which ingredient may or may not be too much. I can only recommend to stay away from this supplement.
Its high levels of collagen help reduce intestinal inflammation, and healing amino acids like proline and glycine keep your immune system functioning properly and help improve memory. Bone broth is what I prescribe most frequently to my patients because it truly helps heal your body from the inside out. You’ll also be surprised at how simple and economical it is to make at home with my Beef Bone Broth Recipe.

Pomegranate juice. Pomegranate juice (you can eat the fruit itself but with its many tiny seeds, it's not nearly as convenient) offers potent antioxidant benefits, says Kulze, which protect the brain from the damage of free radicals. "Probably no part of the body is more sensitive to the damage from free radicals as the brain," says board-certified neurologist David Perlmutter, MD, author of The Better Brain Book. Citrus fruits and colorful vegetables are also high on Perlmutter's list of "brainy" foods because of their antioxidant properties -- "the more colorful the better," he says. Because pomegranate juice has added sugar (to counteract its natural tartness), you don't want to go overboard, says Kulze; she recommends approximately 2 ounces a day, diluted with spring water or seltzer.
Provigil may well confer a temporary advantage on healthy people, but this doesn't mean that it's ready to replace your morning espresso. Anjan Chatterjee told me that there "just aren't enough studies of these drugs in normal people". One study, published recently in the Journal of the American Medical Association, suggests that Provigil can be habit-forming. A group led by Nora Volkow, the director of the National Institute on Drug Abuse, scanned the brains of 10 men after they had been given a placebo, and also after they had been given a dose of modafinil. The modafinil appeared to lead to an increase in the brain chemical dopamine. "Because drugs that increase dopamine have the potential for abuse," Volkow's report concluded, "these results suggest that risk for addiction in vulnerable persons merits heightened awareness." (Cephalon, in a response to the report, notes that Provigil's label urges physicians to monitor patients closely, especially those with a history of drug abuse.) On the website Erowid, where people vividly and anonymously report their experiences with legal and illegal drugs, some modafinil users have described a dependency on the drug. One man, who identified himself as a former biochemistry student, said that he had succeeded in kicking cocaine and opiate habits but couldn't stop using modafinil. Whenever he ran out of the drug, he said, "I start to freak out." After "four to five days" without it, "the head fog starts to come back".
Fortunately for me, the FDA decided Smart Powder’s advertising was too explicit and ordered its piracetam sales stopped; I was equivocal at the previous price point, but then I saw that between the bulk discount and the fire-sale coupon, 3kg was only $99.99 (shipping was amortized over that, the choline, caffeine, and tryptophan). So I ordered in September 2010. As well, I had decided to cap my own pills, eliminating the inconvenience and bad taste. 3kg goes a very long way so I am nowhere close to running out of my pills; there is nothing to report since, as the pills are simply part of my daily routine.
Nothing happened until I was falling asleep, when I became distinctly aware that I was falling asleep. I monitored the entire process and remained lucid, with a measure of free will, as I dreamed, and woke up surprisingly refreshed. While I remembered many of my dreams, some of which were quite long, I couldn't recall how my underpants ended up around my ankles.

Your article was both informative and enjoyable. Indeed the right type of brain food can help our brains overcome any potential damaging brain diseases. In this day and age when there are chemicals in many things we eat, it is nice to know that we can alter potential conditions with the right  brain vitamin. Thank you so much for your generosity and kindness in allowing commenters to link with you too. You articles are quality. Thanks

The power calculation indicates a 20% chance of getting useful information. My quasi-experiment has <70% chance of being right, and I preserve a general skepticism about any experiment, even one as well done as the medical student one seems to be, and give that one a <80% chance of being right; so let’s call it 70% the effect exists, or 30% it doesn’t exist (which is the case in which I save money by dropping fish oil for 10 years).
You don’t need a therapist and certainly not a shaman. Just find someone you trust. It doesn’t matter the plant or what is derived from it, whether it’s LSD, shrooms, or mescaline via legal San Pedro cactus; it’s all the same experience, essentially indistinguishable. Just be sure & take enough. If it’s blotter acid, you need about 5 hits (Leary said that if you don’t have an ego-death ( read: religious) experience, you didn’t take enough, which he suggested to be at least 400 micrograms). Mushrooms vary. Typically, in excess of a few grams, to achieve this same state. San Pedro, though variable, too, requires 12-18 inches or a few (bitter-tasting) dried “stars” (x-section, thin-sliced, in the oven @ 150 degrees, until dry like snack chips).
This supplement contains Vitamins A, C, D, E, B1, B2, B3, and B6, Folate, Biotin, Pantothenic Acid, Copper, Calcium, Selenium, Iron, Manganese, Chromium, Potassium, Molybdenum, Iodine, Magnesium, Zinc, and 692mg of Synergistic and Proprietary Formulation that includes Dimethylaminoethanol, L-Glutamine, Bacopin, L-pyroglutamic Acid, Phyosphatidylserine, DHA Concentrate, Choline, Inositol, N-Acetyl Tyrosine, Bilberry Fruit, Gamma Aminobutyric Acid, Grape Seed Extract, Vinpocetine, Trace Lyte Electrolyte Concentrate, Huperzine A, Boron, and Vanadium.

As discussed in my iodine essay (FDA adverse events), iodine is a powerful health intervention as it eliminates cretinism and improves average IQ by a shocking magnitude. If this effect were possible for non-fetuses in general, it would be the best nootropic ever discovered, and so I looked at it very closely. Unfortunately, after going through ~20 experiments looking for ones which intervened with iodine post-birth and took measures of cognitive function, my meta-analysis concludes that: the effect is small and driven mostly by one outlier study. Once you are born, it’s too late. But the results could be wrong, and iodine might be cheap enough to take anyway, or take for non-IQ reasons. (This possibility was further weakened for me by an August 2013 blood test of TSH which put me at 3.71 uIU/ml, comfortably within the reference range of 0.27-4.20.)

Using neuroenhancers, Seltzer said, "is like customising yourself - customising your brain". For some people, he added, it was important to enhance their mood, so they took antidepressants; but for people like him it was more important "to increase mental horsepower". He said: "It's fundamentally a choice you're making about how you want to experience consciousness." Whereas the 1990s had been about "the personalisation of technology", this decade was about the personalisation of the brain - what some enthusiasts have begun to call "mind hacking".
At this point, I discovered I had run out of magnesium pills and had forgotten to order the magnesium citrate powder I’d intended to. I still had a lot of Noopept pills for the concurrently running second Noopept self-experiment, but since I wanted to wrap up some other experiments with a big analysis at the end of the year, I decided to halt and resume in January 2014.
Alpha Lipoic Acid is a vitamin-like chemical filled with antioxidant properties, that naturally occur in broccoli, spinach, yeast, kidney, liver, and potatoes. The compound is generally prescribed to patients suffering from nerve-related symptoms of diabetes because it helps in preventing damage to the nerve cells and improves the functioning of neurons.
Tomatoes - does that include tinned? And what about passata? And while we are at it, are frozen veg as good [or very nearly] as fresh? I'm particularly thinking of green veg like peas, broad beans, green beans. Fresh peas are a seasonal rarity, so are broad beans and green beans in supermarkets are often rather tired after their long trip from Kenya.

It’s not easy to make it in the modern world, which asks you to be focused and sharp all the time. You have to be creative and learn the new skills all the time. That’s a heavy burden for your brain cells. One day, sooner or later, you have to accept the fact that your brain power and effectiveness are no longer as impressive and reliable as once they were. Brain Pill can help. You don’t have to force yourself to accept your new reality of limited focus and weak ability to learn new things. Brain Pill can refresh your mental clarity and improve your problem-solving and decision-making skills.
Because it’s so nutrient-dense — packing loads of vitamins, minerals and nutrients with very little calories — it’s a great snack option if you’re looking to shed pounds. And while we often eat celery stalks, don’t skip the seeds and leaves; both provide extra health benefits and taste great in things like stir fries and soups. Not sure where to begin with eating more celery? Try my easy Ants on a Log or refreshing Super Hydrator Juice recipes.
A picture is worth a thousand words, particularly in this case where there seems to be temporal effects, different trends for the conditions, and general confusion. So, I drag up 2.5 years of MP data (for context), plot all the data, color by magnesium/non-magnesium, and fit different LOESS lines to each as a sort of smoothed average (since categorical data is hard to interpret as a bunch of dots), which yields:
Cephalon executives have repeatedly said that they do not condone off-label use of Provigil, but in 2002 the company was reprimanded by the FDA for distributing marketing materials that presented the drug as a remedy for tiredness, "decreased activity" and other supposed ailments. And in 2008 Cephalon paid $425m and pleaded guilty to a federal criminal charge relating to its promotion of off-label uses for Provigil and two other drugs. Later this year, Cephalon plans to introduce Nuvigil, a longer-lasting variant of Provigil. Candace Steele, a spokesperson, said: "We're exploring its possibilities to treat excessive sleepiness associated with schizophrenia, bipolar depression, traumatic injury and jet lag." Though she emphasised that Cephalon was not developing Nuvigil as a neuroenhancer, she noted: "As part of the preparation for some of these diseases, we're looking to see if there's improvement in cognition."

In that year, Dr. Corneliu Giurgea, a Romanian scientist, synthesized piracetam for the first time. Piracetam is classified as a nootropic, although the term nootropic was not used until 1972.[2] Dr. Giurgea coined the term “nootropic” by combining the Greek words for mind (nous) and bend (trepein).  Nootropic literally translates into the phrase “mind bender.”

Though coffee gives instant alertness and many cups of the beverage are downed throughout the day, the effect lasts only for a short while. People who drink coffee every day may develop caffeine tolerance; this is the reason why it is still important to control your daily intake. It is advisable that an individual should not consume more than 300mg of coffee a day. Caffeine, the world’s favourite nootropic has very less side effects but if consumed abnormally high can result in nausea, restlessness, nervousness and hyperactivity. This is the reason why people who need increased sharpness would rather induce L-theanine, or some other Nootropic, along with caffeine. Today, you can find various smart drugs that contain caffeine in them. OptiMind , one of the best and most sought-after nootropic in the U.S, containing caffeine, is considered more effective and efficient when compared to other focus drugs present in the market today.
What worries me about amphetamine is its addictive potential, and the fact that it can cause stress and anxiety. Research says it’s only slightly likely to cause addiction in people with ADHD, [7] but we don’t know much about its addictive potential in healthy adults. We all know the addictive potential of methamphetamine, and amphetamine is closely related enough to make me nervous about so many people giving it to their children. Amphetamines cause withdrawal symptoms, so the potential for addiction is there.
Phillips told me that, much as he believes in neuroenhancers, he did not want to be "the poster boy for smart-in-a-pill". At one point, he said: "We really don't know the possible implications for long-term use of these things." (He recently stopped taking Provigil every day, replacing it with another prescription stimulant.) Nor does he think we need to be turning up the crank another notch on how hard we work. "But," he said, "the baseline competitive level is going to reorientate around what these drugs make possible, and you can choose to compete or not."
Past noon, I began to feel better, but since I would be driving to errands around 4 PM, I decided to not risk it and take an hour-long nap, which went well, as did the driving. The evening was normal enough that I forgot I had stayed up the previous night, and indeed, I didn’t much feel like going to bed until past midnight. I then slept well, the Zeo giving me a 108 ZQ (not an all-time record, but still unusual).
One should note the serious caveats here: it is a small in vitro study of a single category of human cells with an effect size that is not clear on a protein which feeds into who-knows-what pathways. It is not a result in a whole organism on any clinically meaningful endpoint, even if we take it at face-value (many results never replicate). A look at followup work citing Rapuri et al 2007 is not encouraging: Google Scholar lists no human studies of any kind, much less high-quality studies like RCTs; just some rat followups on the calcium effect. This is not to say Rapuri et al 2007 is a bad study, just that it doesn’t bear the weight people are putting on it: if you enjoy caffeine, this is close to zero evidence that you should reduce or drop caffeine consumption; if you’re taking too much caffeine, you already have plenty of reasons to reduce; if you’re drinking lots of coffee, you already have plenty of reasons to switch to tea; etc.
B vitamins are also sold with claims of enhancing memory, usually rationalized by their reduction of homocysteine, a chemical in the blood that may affect circulation in the brain. No benefits from B vitamin intake have been demonstrated when it comes to memory or cognitive function except in the case of people who have high homocysteine levels due to a diet that is very low in B vitamins. There is some concern that folic acid, one of the B vitamins, may spur the growth of polyps in the colon at doses greater than 800 micrograms a day. Phosphatidyl serine is a natural component of nerve cell membranes and its promoters argue that a deficiency leads to impaired communication between nerve cells which in turn impairs cognitive function. Sounds reasonable, except that proper controlled trials have come up empty. The same goes for vinpocetine, a compound originally isolated from the lesser periwinkle plant by Hungarian chemist Csaba Szantay in 1975. It is widely used in Europe to treat strokes and memory problems with claims of increased circulation to the brain. It does indeed increase circulation, much like ginkgo, but there is no compelling evidence for memory improvement.
The basic idea is to remedy a deficiency (not look for acute stimulant effects) and magnesium has a slow excretion rate18, so week-long blocks seem appropriate. I can reuse the same methodology as the lithium self-experiment. The response variables will be the usual mood/productivity self-rating and, since I was originally interested in magnesium for possible sleep quality improvements, a standardized score of sleep latency + # of awakenings + time spent awake (the same variable as my potassium sleep experiment).
Supplements, medications, and coffee certainly might play a role in keeping our brains running smoothly at work or when we’re trying to remember where we left our keys. But the long-term effects of basic lifestyle practices can’t be ignored. “For good brain health across the life span, you should keep your brain active,” Sahakian says. “There is good evidence for ‘use it or lose it.’” She suggests brain-training apps to improve memory, as well as physical exercise. “You should ensure you have a healthy diet and not overeat. It is also important to have good-quality sleep. Finally, having a good work-life balance is important for well-being.” Try these 8 ways to get smarter while you sleep.
“We didn’t see significant long-term effects from the dosage used,” said Wen-Jun Gao, a professor of neurobiology at the Drexel University College of Medicine, and one of the authors of the study. He added that the brain doesn’t fully stop developing until age 25 or 30, making cognitive enhancement potentially risky even for users who are well into adulthood.

Exercise is also important, says Lebowitz. Studies have shown it sharpens focus, elevates your mood and improves concentration. Likewise, maintaining a healthy social life and getting enough sleep are vital, too. Studies have consistently shown that regularly skipping out on the recommended eight hours can drastically impair critical thinking skills and attention.
Much of what she says is standard health advice. Avoid trans fats. Eat fresh vegetables and fruit. Avoid processed foods. Limit red meat consumption. It’s better to get your nutrients from food than from supplement pills. Exercise, get adequate sleep, and avoid stress. Since the brain runs on glucose, she wouldn’t agree with the low-carb diet folks; she says we need adequate sources of glucose in our diet, and recommends complex carbs, paying attention to the glycemic index.
We did note a significant warning with this product, namely that the caffeine it contains may cause a negative impact, mainly that some users may experience the jitters. Their dosage suggests that one can take up to 6 pills a day, which we felt was too many. These issues made us a little wary of the product, even though they seem to know the right ingredients to include.
Obviously, as you can see, there are a host of benefits to the better living through science to be had through optimizing your brain with specific compounds. So, putting aside the intriguing topic of psychedelics for the moment (yes, yes, I know you probably want to know how to microdose with LSD or psilocybin), what’s the difference between a smart drug and a nootropic, and how do you choose which to take? You’re about to find out.
Paul Phillips was unusual for a professional poker player. When he joined the circuit in the late 1990s he was already a millionaire: a twentysomething tech guy who helped found an internet portal called go2net and cashed in at the right moment. He was cerebral and at times brusque. On the international poker scene Phillips cultivated a geeky New Wave style. He wore vintage shirts in wild geometric patterns; his hair was dyed orange or silver one week, shaved off the next. Most unusual of all, Phillips talked freely about taking prescription drugs - Adderall and, especially, Provigil - in order to play better cards.
According to Dr Vivette Glover, Director of the Foetal and Neonatal Stress and Research Centre, at any one time during pregnancy, one in every ten women will be depressed and around one in every thirty will be depressed both during pregnancy and the postnatal period (1). It is not yet understood exactly what causes the symptoms associated to depression during and after pregnancy. However, factors such as the large changes that the body undergoes due to the demands of the growing foetus, as well as breastfeeding and potential sleep deprivation, can all play a significant role in how the body deals with stress. It is during this period of time that our bodies require more nourishment from food than ever and it can also be at exactly this time when we perhaps struggle to prioritise nutrition due to lack of energy, loss of appetite or sickness. 
Whole pill at 3 AM. I spend the entire morning and afternoon typing up a transcript of Earth in My Window. I tried taking a nap around 10 AM, but during the hour I was down, I had <5m of light sleep, the Zeo said. After I finished the transcript (~16,600 words with formatting), I was completely pooped and watched a bunch of Mobile Suit Gundam episodes, then I did Mnemosyne. The rest of the night was nothing to write home about either - some reading, movie watching, etc. Next time I will go back to split-doses and avoid typing up 110kB of text. On the positive side, this is the first trial I had available the average daily grade Mnemosyne 2.0 plugin. The daily averages all are 3-point-something (peaking at 3.89 and flooring at 3.59), so just graphing the past 2 weeks, the modafinil day, and recovery days: ▅█▅▆▄▆▄▃▅▄▁▄▄ ▁ ▂▄▄█. Not an impressive performance but there was a previous non-modafinil day just as bad, and I’m not too sure how important a metric this is; I must see whether future trials show similar underperformance. Nights: 11:29; 9:22; 8:25; 8:41.
Nuts and seeds. Nuts and seeds are good sources of vitamin E, says Pratt, explaining that higher levels of vitamin E correspond with less cognitive decline as you get older. Add an ounce a day of walnuts, hazelnuts, Brazil nuts, filberts, almonds, cashews, peanuts, sunflower seeds, sesame seeds, flax seed, and unhydrogenated nut butters such as peanut butter, almond butter, and tahini. Raw or roasted doesn't matter, although if you're on a sodium-restricted diet, buy unsalted nuts.
Dr Hart talked through food intolerance tests that are available through a number of well known companies, including York Test for whom she is Scientific Director. A possible strategy could be to use such testing to identify intolerances, follow an elimination protocol, temporarily removing on foods triggering an IgG response; and then work to improve your gut health to support longer term well-being. Foods that are rich in collagen and its amino acids, like glycine and proline, are great for healing connective tissue, which is what the intestines are made up of. A traditional food, rich in these amino acids, that has made its way into our kitchens again after rediscovering its therapeutic properties is bone broth. Another example of a group of traditional foods that can be used therapeutically in building digestive health, are fermented foods such as kefir, sauerkraut and kimchi. These are abundant in probiotics, which are the ‘good’ bacteria our digestive system needs to help keep a good balance and protect the intestinal barrier from pathogens, toxins and parasites. Once these foods have been introduced on an everyday basis along with eating a healthy nutrient-dense diet and the possible use of supplements to help restore balance, you may be able to reintroduce foods that were previously triggering an IgG response carefully, one at a time, whilst monitoring symptoms.

Even party drugs are going to work: Biohackers are taking recreational drugs like LSD, psilocybin mushrooms, and mescaline in microdoses—about a tenth of what constitutes a typical dose—with the goal of becoming more focused and creative. Many who’ve tried it report positive results, but real research on the practice—and its safety—is a long way off. “Whether microdosing with LSD improves creativity and cognition remains to be determined in an objective experiment using double-blind, placebo-controlled methodology,” Sahakian says.

Christopher, love your heart for Pete’s security in who he is to The Lord. So cool. Brother, God does judge. Jesus is even referred to as “the righteous judge” (2 Timothy 4:8). In the first 5 verses of Romans 2, the judgment of God is even mentioned 3 times. Matthew 25:46 speaks of what will happen when God judges – that some “will go away into eternal punishment, but the righteous into eternal life.” Those who believe in Jesus Christ as their Lord and Savior who died for their sins and rose again will be and are “by grace… saved through faith” (Ephesians 2:8-9) in Jesus as such, having their sins forgiven and the righteousness of Jesus credited to them. (Romans 4:22-25) Thank you, Lord!

along with the previous bit of globalization is an important factor: shipping is ridiculously cheap. The most expensive S&H in my modafinil price table is ~$15 (and most are international). To put this in perspective, I remember in the 90s you could easily pay $15 for domestic S&H when you ordered online - but it’s 2013, and the dollar has lost at least half its value, so in real terms, ordering from abroad may be like a quarter of what it used to cost, which makes a big difference to people dipping their toes in and contemplating a small order to try out this ’nootropics thing they’ve heard about.

When I spoke with Sahakian she had just flown from England to Scottsdale, Arizona, to attend a conference, and she was tired. "We may be healthy and high-functioning, and think of ourselves that way," she told me, "but it's very rare that we are actually functioning at our optimal level. Take me. I'm over here and I've got jet lag and I've got to give a talk tonight and perform well in what will be the middle of the night, UK time." She mentioned businessmen who have to fly back and forth across the Atlantic: "The difference between making a deal and not is huge, and they sometimes only have one meeting to try and do it." She added: "We are a society that so wants a quick fix that many people are happy to take drugs."
Potassium citrate powder is neither expensive nor cheap: I purchased 453g for $21. The powder is crystalline white, dissolves instantly in water, and largely tasteless (sort of saline & slightly unpleasant). The powder is 37% potassium by weight (the formula is C6H5K3O7) so 453g is actually 167g of potassium, so 80-160 days’ worth depending on dose.
Between midnight and 1:36 AM, I do four rounds of n-back: 50/39/30/55%. I then take 1/4th of the pill and have some tea. At roughly 1:30 AM, AngryParsley linked a SF anthology/novel, Fine Structure, which sucked me in for the next 3-4 hours until I finally finished the whole thing. At 5:20 AM, circumstances forced me to go to bed, still having only taken 1/4th of the pill and that determines this particular experiment of sleep; I quickly do some n-back: 29/20/20/54/42. I fall asleep in 13 minutes and sleep for 2:48, for a ZQ of 28 (a full night being ~100). I did not notice anything from that possible modafinil+caffeine interaction. Subjectively upon awakening: I don’t feel great, but I don’t feel like 2-3 hours of sleep either. N-back at 10 AM after breakfast: 25/54/44/38/33. These are not very impressive, but seem normal despite taking the last armodafinil ~9 hours ago; perhaps the 3 hours were enough. Later that day, at 11:30 PM (just before bed): 26/56/47.
For more in-depth personalised support, some people find nutritional therapy hugely beneficial. To find a suitable therapist, please head to BANT (British Association of Applied Nutrition and Nutritional Therapy) or contact our not-for-profit clinic, the Brain Bio Centre (, which offers expertise in nutritional therapy for mental health conditions including depression, on 0208 332 9600 or If you feel you need more immediate help, for whatever it is that you’re going through, theSamaritans helpline offer support 24 hours a day, 365 days a year and can point you in the right direction of getting further help.
Chatterjee told me that many people who come to his clinic are cognitively preoccupied versions of what doctors call the "worried well". He had just seen a middle-aged woman, a successful Philadelphia lawyer, who mentioned having to struggle a bit to come up with certain names. "Here's an example of someone who by most measures is doing perfectly fine," Chatterjee said. "She's not having any trouble at work. But she notices she's having some problems, and it's very hard to know how much of that is just getting older." Of course, people in her position could strive to get regular exercise and plenty of intellectual stimulation, both of which have been shown to help maintain cognitive function. But maybe they're already doing so and want a bigger mental rev-up, or maybe they want something easier than sweaty workouts and Russian novels: they want a pill.
For obvious reasons, it’s difficult for researchers to know just how common the “smart drug” or “neuro-enhancing” lifestyle is. However, a few recent studies suggest cognition hacking is appealing to a growing number of people. A survey conducted in 2016 found that 15% of University of Oxford students were popping pills to stay competitive, a rate that mirrored findings from other national surveys of UK university students. In the US, a 2014 study found that 18% of sophomores, juniors, and seniors at Ivy League colleges had knowingly used a stimulant at least once during their academic career, and among those who had ever used uppers, 24% said they had popped a little helper on eight or more occasions. Anecdotal evidence suggests that pharmacological enhancement is also on the rise within the workplace, where modafinil, which treats sleep disorders, has become particularly popular.
We have established strict criteria for reviewing brain enhancement supplements. Our reviews are clear, detailed, and informative to help you find supplements that deliver the best results. You can read our reviews, learn about the best nootropic ingredients, compare formulas, and find out how each supplement performed according to specific criteria.

Attention Deficit and Hyperactivity Disorder (ADHD) is a condition that relates to a collection of behavioural symptoms such as hyperactivity, impulsiveness and inattentiveness. It is most commonly diagnosed in childhood between the ages of 6 and 12 when disruptive behaviour begins to show, however, due to a growing awareness of the condition, it is also becoming common among adults. According to the thinktank Demos, the cost of undiagnosed ADHD in adults in the UK who are unable to work or hold down a full-time job are estimated to cost billions of pounds to the nation. They warn that too many may be going through life struggling, unable to access the support ot diagnosis they need, which means there could be a huge amount of wasted talent.
Pyritinol: Pyritinol has anti-oxidant effects for supporting the long-term health of the brain. But its primary benefit is aiding glucose uptake for periods of extended mental strain. If you are studying or working for a long period of time, your brain will start to diminish its glucose (sugar) stores which are the primary way that the brain derives its energy.

Working memory has been likened to a mental scratch pad: you use it to keep relevant data in mind while you're completing a task. (Imagine a cross-examination, in which a lawyer has to keep track of the answers a witness has given and formulate new questions based on them.) In one common test subjects are shown a series of items - usually letters or numbers - and then presented with challenges: was this number or letter in the series? Was this one? In the working-memory tests, subjects performed better on neuroenhancers, though several of the studies suggested that the effect depended on how good a subject's working memory was to begin with: the better it was, the less benefit the drugs provided.
A Romanian psychologist and chemist named Corneliu Giurgea started using the word nootropic in the 1970s to refer to substances that improve brain function, but humans have always gravitated toward foods and chemicals that make us feel sharper, quicker, happier, and more content. Our brains use about 20 percent of our energy when our bodies are at rest (compared with 8 percent for apes), according to National Geographic, so our thinking ability is directly affected by the calories we’re taking in as well as by the nutrients in the foods we eat. Here are the nootropics we don’t even realize we’re using, and an expert take on how they work.
There are plenty of brain supplements on the market, but none with the same combinations of potent and promising ingredients. If you want to maximize your ability to excel  – at everything you do – your brain must be firing on all cylinders – all day, every day. You must protect and preserve your brain function, as it will diminish – it’s the reality of being human.
The BoredAt websites - which allow college students to chat idly while they're ostensibly studying - are filled with messages about Adderall. Posts like these, from the BoredAtPenn site, are typical: "I have some Adderall - I'm sitting by room 101.10 in a grey shirt and headphones"; "I have Adderall for sale 20mg for $15"; "I took Adderall at 8pm, it's 6:30am and I've barely blinked." On the Columbia site one poster complains that her friends take Adderall "like candy", adding: "I don't want to be at a disadvantage to everyone else. Is it really that dangerous? My grades weren't that great this year and I could do with a bump." A Columbia student responds: "It's probably not a good idea if you're not prescribed", but offers practical advice anyway: "Keep the dose normal and don't grind them up or snort them." Occasional dissenters ("I think there should be random drug testing at every exam") are drowned out by testimonials like this one, from the BoredAtHarvard site: "I don't want to be a pusher or start people on something bad, but Adderall is amazing."
Flaxseed oil is, ounce for ounce, about as expensive as fish oil, and also must be refrigerated and goes bad within months anyway. Flax seeds on the other hand, do not go bad within months, and cost dollars per pound. Various resources I found online estimated that the ALA component of human-edible flaxseed to be around 20% So Amazon’s 6lbs for $14 is ~1.2lbs of ALA, compared to 16fl-oz of fish oil weighing ~1lb and costing ~$17, while also keeping better and being a calorically useful part of my diet. The flaxseeds can be ground in an ordinary food processor or coffee grinder. It’s not a hugely impressive cost-savings, but I think it’s worth trying when I run out of fish oil.

So with these 8 results in hand, what do I think? Roughly, I was right 5 of the days and wrong 3 of them. If not for the sleep effect on #4, which is - in a way - cheating (one hopes to detect modafinil due to good effects), the ratio would be 5:4 which is awfully close to a coin-flip. Indeed, a scoring rule ranks my performance at almost identical to a coin flip: -5.49 vs -5.5420. (The bright side is that I didn’t do worse than a coin flip: I was at least calibrated.)
Eat a healthy diet.  While the best nootropic supplements can help fuel your brain, they cannot fill every gap in your diet.  If you want your brain to function at its best, a healthy, nutritious, varied diet is essential.  Make sure that you are eating fatty fish and foods fortified with DHA omega-3 fatty acids.  Get plenty of vitamin E and antioxidants like lutein.
The fact of the matter is, though, that the phrase ‘best brain pill’ doesn’t cover any of the bases you’d want an informative article to cover. The human brain is a large and complex thing, and there are many different kinds of pills, supplements, and medications that you can take to improve or affect different areas and functions. Many more of those pills, supplements and medications you take when it breaks down or glitches, to help control harmful or disorienting symptoms of various mental diseases.
What worries me about amphetamine is its addictive potential, and the fact that it can cause stress and anxiety. Research says it’s only slightly likely to cause addiction in people with ADHD, [7] but we don’t know much about its addictive potential in healthy adults. We all know the addictive potential of methamphetamine, and amphetamine is closely related enough to make me nervous about so many people giving it to their children. Amphetamines cause withdrawal symptoms, so the potential for addiction is there.
On the other hand, other SCFAs such as butyrate are well known for having health-promoting properties, such as producing anti-inflammatory effects by being able to regulate T-cells (immune cells) in the colon, as well as helping to maintain a healthy gut barrier function. In order to increase the favourable, health-promoting SCFAs, such as butyrate, it’s important to increase the intake of vegetables, fruits and good fats such as grass-fed butter, coconut oil, nuts and seeds, olive oil and avocado. These provide the bacteria with prebiotics, which is in other words, food for gut bacteria to feed on. Foods such as those listed above contain the right nourishment for gut bacteria to produce SCFAs that support health. Eating traditional foods such as fermented cabbage and other vegetables, as well as bone broth, are also rich in prebiotics and nutrients that support a healthy microbiome and digestive system.

We already knew that rosemary oil has a variety of benefits, but did you know that the herb does, too? Carnosic acid, one of the main ingredients in rosemary, helps protect the brain from neurodegeneration. It does this by protecting the brain against chemical free radicals, which are linked to neurodegeneration, Alzheimer’s, strokes and normal aging in the brain. (10)
Whether you want to optimise your nutrition during exam season or simply want to stay sharp in your next work meeting, paying attention to your diet can really pay off. Although there is no single 'brain food' that can protect against age-related disorders such as Alzheimers' or dementia, and there are many other medical conditions that can affect the brain, paying attention to what you eat gives you the best chance of getting all the nutrients you need for cognitive health.
(We already saw that too much iodine could poison both adults and children, and of course too little does not help much - iodine would seem to follow a U-curve like most supplements.) The listed doses at often are ridiculously large: 10-50mg! These are doses that seems to actually be dangerous for long-term consumption, and I believe these are doses that are designed to completely suffocate the thyroid gland and prevent it from absorbing any more iodine - which is useful as a short-term radioactive fallout prophylactic, but quite useless from a supplementation standpoint. Fortunately, there are available doses at Fitzgerald 2012’s exact dose, which is roughly the daily RDA: 0.15mg. Even the contrarian materials seem to focus on a modest doubling or tripling of the existing RDA, so the range seems relatively narrow. I’m fairly confident I won’t overshoot if I go with 0.15-1mg, so let’s call this 90%.
Clarke and Sokoloff (1998) remarked that although [a] common view equates concentrated mental effort with mental work…there appears to be no increased energy utilization by the brain during such processes (p. 664), and …the areas that participate in the processes of such reasoning represent too small a fraction of the brain for changes in their functional and metabolic activities to be reflected in the energy metabolism of the brain… (p. 675).

(In particular, I don’t think it’s because there’s a sudden new surge of drugs. FDA drug approval has been decreasing over the past few decades, so this is unlikely a priori. More specifically, many of the major or hot drugs go back a long time. Bacopa goes back millennia, melatonin I don’t even know, piracetam was the ’60s, modafinil was ’70s or ’80s, ALCAR was ’80s AFAIK, Noopept & coluracetam were ’90s, and so on.)

This would be a very time-consuming experiment. Any attempt to combine this with other experiments by ANOVA would probably push the end-date out by months, and one would start to be seriously concerned that changes caused by aging or environmental factors would contaminate the results. A 5-year experiment with 7-month intervals will probably eat up 5+ hours to prepare <12,000 pills (active & placebo); each switch and test of mental functioning will probably eat up another hour for 32 hours. (And what test maintains validity with no practice effects over 5 years? Dual n-back would be unusable because of improvements to WM over that period.) Add in an hour for analysis & writeup, that suggests >38 hours of work, and 38 \times 7.25 = 275.5. 12,000 pills is roughly $12.80 per thousand or $154; 120 potassium iodide pills is ~$9, so \frac{365.25}{120} \times 9 \times 5 = 137.
Though their product includes several vitamins including Bacopa, it seems to be missing the remaining four of the essential ingredients: DHA Omega 3, Huperzine A, Phosphatidylserine and N-Acetyl L-Tyrosine. It missed too many of our key criteria and so we could not endorse this product of theirs. Simply, if you don’t mind an insufficient amount of essential ingredients for improved brain and memory function and an inclusion of unwanted ingredients – then this could be a good fit for you.
The magnesium was neither randomized nor blinded and included mostly as a covariate to avoid confounding (the Noopept coefficient & t-value increase somewhat without the Magtein variable), so an OR of 1.9 is likely too high; in any case, this experiment was too small to reliably detect any effect (~26% power, see bootstrap power simulation in the magnesium section) so we can’t say too much.
The main concern with pharmaceutical drugs is adverse effects, which also apply to nootropics with undefined effects. Long-term safety evidence is typically unavailable for nootropics.[13] Racetams — piracetam and other compounds that are structurally related to piracetam — have few serious adverse effects and low toxicity, but there is little evidence that they enhance cognition in people having no cognitive impairments.[19]
