“Most people assume that because it’s a supplement, it can’t be bad for you because it’s natural,” says Louis Kraus, M.D., a psychiatrist with Rush University Medical Center in Chicago. In 2016, he chaired a committee that investigated nootropics for the American Medical Association. After reviewing the science, the committee found little to no evidence to support the efficacy or safety of nootropics.
See Melatonin for information on effects & cost; I regularly use melatonin to sleep (more to induce sleep than prolong or deepen it), and investigating with my Zeo, it does seem to improve & shorten my sleep. Some research suggests that higher doses are not necessarily better and may be overkill, so each time I’ve run out, I’ve been steadily decreasing the dose from 3mg to 1.5mg to 1mg, without apparently compromising the usefulness.
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.
Intrigued by old scientific results & many positive anecdotes since, I experimented with microdosing LSD - taking doses ~10μg, far below the level at which it causes its famous effects. At this level, the anecdotes claim the usual broad spectrum of positive effects on mood, depression, ability to do work, etc. After researching the matter a bit, I discovered that as far as I could tell, since the original experiment in the 1960s, no one had ever done a blind or even a randomized self-experiment on it.
Adderall, a stimulant composed of mixed amphetamine salts, is commonly prescribed for children and adults who have been given a diagnosis of attention-deficit hyperactivity disorder (ADHD). But in recent years Adderall and Ritalin, another stimulant, have been adopted as cognitive enhancers: drugs that high-functioning, overcommitted people take to become higher-functioning and more overcommitted. (Such use is "off label", meaning that it does not have the approval of either the drug's manufacturer or the FDA, America's Food and Drug Administration.) College campuses have become laboratories for experimentation with neuroenhancement, and Alex was an ingenious experimenter. His brother had received a diagnosis of ADHD, and in his first year as an undergraduate Alex obtained an Adderall prescription for himself by describing to a doctor symptoms that he knew were typical of the disorder. During his college years, Alex took 15mg of Adderall most evenings, usually after dinner, guaranteeing that he would maintain intense focus while losing "any ability to sleep for approximately eight to 10 hours". In his second year, he persuaded the doctor to add a 30mg "extended-release" capsule to his daily regime.
Piracetam is well studied and is credited by its users with boosting their memory, sharpening their focus, heightening their immune system, even bettering their personalities. But it’s only one of many formulations in the racetam drug family. Newer ones include aniracetam, phenylpiracetam and oxiracetam. All are available online, where their efficacy and safety are debated and reviewed on message boards and in podcasts.

Can the Folic Acid in this Supplement be Taken by Men? Folic acid is most well-known for its use in prenatal vitamins during pregnancy and breastfeeding. However, it is an important nutrient for the bodies of both men and women. The level of folic acid in Cognizance is nowhere near as high as the levels found in prenatal vitamins taken during pregnancy, making it safe for use by both genders. Is it Safe? All of the ingredients in Cognizance have been tested individually for their safety of use. They have also been monitored in use together, to ensure there are no side effects from the combination of ingredients.1 Though Cognizance is safe, you should still speak to your doctor if you are under the age of 18, have a pre-existing medical condition, or are a woman who is pregnant or nursing.
Next generation medical imaging and genomic sequencing studies, including my own work, have helped reveal that some foods are neuro-protective, literally shielding the brain from harm and supporting cognitive fitness over the course of a lifetime. Conversely, other foods are harmful for the brain, slowing us down in general, making us feel sluggish and tired, while at the same time increasing our risk of dementia.
Long story short, aging is your brain’s worst enemy. The same applies to all organs of our body, but the brain suffers the most. Both neurotransmitters and neurons are taking the blow too. As a result, the neuron communication is affected. Now, this may seem like the rocket science to you, but it’s enough to say, serotonin and dopamine are the most important neurotransmitters. Without these components, you can forget about good mood. Serotonin and dopamine levels drop at a rate of approximately 10% for every decade you add to your age.
The third category was cognitive control - how effectively you can check yourself in circumstances where the most natural response is the wrong one. A classic test is the Stroop Task, in which people are shown the name of a colour (let's say orange) written in a different colour (let's say purple). They're asked to read the word (which is easy, because our habitual response to a word is to read it) or to name the ink colour (which is harder, because our first impulse is to say "orange"). These studies presented a more mixed picture, but overall they showed some benefit "for most normal healthy subjects" - especially for people who had inherently poorer cognitive control.
Feeling behind, I resolved to take some armodafinil the next morning, which I did - but in my hurry I failed to recall that 200mg armodafinil was probably too much to take during the day, with its long half life. As a result, I felt irritated and not that great during the day (possibly aggravated by some caffeine - I wish some studies would be done on the possible interaction of modafinil and caffeine so I knew if I was imagining it or not). Certainly not what I had been hoping for. I went to bed after midnight (half an hour later than usual), and suffered severe insomnia. The time wasn’t entirely wasted as I wrote a short story and figured out how to make nicotine gum placebos during the hours in the dark, but I could have done without the experience. All metrics omitted because it was a day usage.
Woo understands that when selling brain drugs, skepticism comes with the territory. "The typical first reaction is, this is bullshit, you guys are snake-oil salesmen," he says. "We're not medical doctors nor biochemistry experts, but we are experts in building teams and building products. Like how Elon Musk attacks rockets and electric cars from 'first principles,' we see ourselves as applying Silicon Valley aesthetics and operational know-how to the murky world of nootropics."
Some suggested that the lithium would turn me into a zombie, recalling the complaints of psychiatric patients. But at 5mg elemental lithium x 200 pills, I’d have to eat 20 to get up to a single clinical dose (a psychiatric dose might be 500mg of lithium carbonate, which translates to ~100mg elemental), so I’m not worried about overdosing. To test this, I took on day 1 & 2 no less than 4 pills/20mg as an attack dose; I didn’t notice any large change in emotional affect or energy levels. And it may’ve helped my motivation (though I am also trying out the tyrosine).
However, normally when you hear the term nootropic kicked around, people really mean a “cognitive enhancer” — something that does benefit thinking in some way (improved memory, faster speed-of-processing, increased concentration, or a combination of these, etc.), but might not meet the more rigorous definition above.  “Smart drugs” is another largely-interchangeable term.
The next cheap proposition to test is that the 2ml dose is so large that the sedation/depressive effect of nicotine has begun to kick in. This is easy to test: take much less, like half a ml. I do so two or three times over the next day, and subjectively the feeling seems to be the same - which seems to support that proposition (although perhaps I’ve been placebo effecting myself this whole time, in which case the exact amount doesn’t matter). If this theory is true, my previous sleep results don’t show anything; one would expect nicotine-as-sedative to not hurt sleep or improve it. I skip the day (no cravings or addiction noticed), and take half a ml right before bed at 11:30; I fall asleep in 12 minutes and have a ZQ of ~105. The next few days I try putting one or two drops into the tea kettle, which seems to work as well (or poorly) as before. At that point, I was warned that there were some results that nicotine withdrawal can kick in with delays as long as a week, so I shouldn’t be confident that a few days off proved an absence of addiction; I immediately quit to see what the week would bring. 4 or 7 days in, I didn’t notice anything. I’m still using it, but I’m definitely a little nonplussed and disgruntled - I need some independent source of nicotine to compare with!
He first took up the game in 1995, when he was in college. He recalled: "It was very mathematical, but you could also inject yourself into the game and manipulate the other guy with words" - more so than in a game like chess. Phillips soon felt that he had mastered the strategic aspects of poker. The key variable was execution. At tournaments he needed to be able to stay focused for 14 hours at a stretch, often for several days, but he found it difficult to do so. In 2003, a doctor gave him a diagnosis of ADHD and he began taking Adderall. Within six months, he had won $1.6m at poker - far more than he'd won in the previous four years. Adderall not only helped him concentrate, it also helped him resist the impulse to keep playing losing hands out of boredom. In 2004, Phillips asked his doctor to give him a prescription for Provigil, which he added to his Adderall regimen. He took 200-300mg of Provigil a day, which he felt helped him settle into an even more serene and objective state of mindfulness; as he put it, he felt "less like a participant than an observer - and a very effective one". Though Phillips sees neuroenhancers as essentially steroids for the brain, they haven't yet been banned from poker competitions.

As mentioned above, eating foods that are rich in indigestible fibre such as vegetables and fruits, as well as eating good fats that are found in grass-fed butter, nuts and seeds, olive oil, coconut oil and avocado, provide bacteria with prebiotics that help to produce the ‘friendly’ short-chain fatty acids such as butyrate. Avoiding processed foods that contain calcium propionate, which lead to higher levels of propionic acid - the not so friendly short-chain fatty acid - is also another key strategy to support the gut-brain link.
There are a number of smart drugs on the market, the most well-known of which are probably Adderall and Ritalin. Both are technically known as psychostimulants, which means that they stimulate increased activity of the central nervous system: the brain and spinal cord. There are also two other common smart drugs, specifically Modafinil and a class of something called “ampakines”. You’re about to learn how each of them works and the benefits and potential risks therein.
Bacopa Monnieri is probably one of the safest and most effective memory and mood enhancer nootropic available today with the least side-effects. In some humans, a majorly extended use of Bacopa Monnieri can result in nausea. Amongst AlternaScript’s, primary products is Optimind, a nootropic supplement which largely constitutes of Bacopa Monnieri as one of the main ingredients.
Besides Adderall, I also purchased on Silk Road 5x250mg pills of armodafinil. The price was extremely reasonable, 1.5btc or roughly $23 at that day’s exchange rate; I attribute the low price to the seller being new and needing feedback, and offering a discount to induce buyers to take a risk on him. (Buyers bear a large risk on Silk Road since sellers can easily physically anonymize themselves from their shipment, but a buyer can be found just by following the package.) Because of the longer active-time, I resolved to test the armodafinil not during the day, but with an all-nighter.
Another prescription stimulant medication, modafinil (known by the brand name Provigil), is usually prescribed to patients suffering from narcolepsy and shift-work sleep disorder, but it might turn out to have broader applications. “We have conducted at the University of Cambridge double-blind, placebo-controlled studies in healthy people using modafinil and have found improvements in cognition, including in working memory,” Sahakian says. However, she doesn’t think everyone should start using the drug off-label. “There are no long-term safety and efficacy studies of modafinil in healthy people, and so it is unclear what the risks might be.”
Methylphenidate was accepted into medical practice in 1960 as a way to treat narcolepsy and ADHD. It works by inhibiting the reuptake of dopamine and norepinephrine into the nervous system, causing a flooding of dopamine and norepinephrine in the synapse between the nerves, which in turn leads to amplified signaling between neurons. It’s been said that these effects are basically the same as those of amphetamines (see more details below), which are synthetic, addictive, mood-altering drugs, used illegally in sports as a stimulant and also legally as a prescription drug – like Ritalin – to treat children with ADD and adults with narcolepsy.

My impression after the first two days (2 doses of 400mg each, one with breakfast & then lunch) was positive. I did not have the rumored digestion problems, and the first day went excellently: I was up until 1:30AM working and even then didn’t feel like going to bed - and I probably should have since I then slept abominably, which made the second day merely a good day. The third day I took none and it was an ordinary day. This is consistent with what I expected from the LEF l-threonate & TruBrain glycinate/lycinate, and so it is worth investigating with a self-experiment.

If you want to focus on boosting your brain power, Lebowitz says you should primarily focus on improving your cardiovascular health, which is "the key to good thinking." For example, high blood pressure and cholesterol, which raise the risk of heart disease, can cause arteries to harden, which can decrease blood flow to the brain. The brain relies on blood to function normally.
Wild salmon. Deep-water fish, such as salmon, are rich in omega-3 essential fatty acids, which are essential for brain function, says Kulze. Both she and Pratt recommend wild salmon for its "cleanliness" and the fact that it is in plentiful supply. Omega-3s also contain anti-inflammatory substances. Other oily fish that provide the benefits of omega-3s are sardines and herring, says Kulze; she recommends a 4-ounce serving, two to three times a week.
On 8 April 2011, I purchased from Smart Powders (20g for $8); as before, some light searching seemed to turn up SP as the best seller given shipping overhead; it was on sale and I planned to cap it so I got 80g. This may seem like a lot, but I was highly confident that theanine and I would get along since I already drink so much tea and was a tad annoyed at the edge I got with straight caffeine. So far I’m pretty happy with it. My goal was to eliminate the physical & mental twitchiness of caffeine, which subjectively it seems to do.
See Melatonin for information on effects & cost; I regularly use melatonin to sleep (more to induce sleep than prolong or deepen it), and investigating with my Zeo, it does seem to improve & shorten my sleep.

Since Racetams result in increased uptake and demand for acetylcholine, stacking choline with this nootropic will further enhance your results. Studies have shown that choline supplementation can improve performance on memory tests as well as social behavior. Choline also plays a key role in the production of phospholipids that are incorporated into brain cell membranes.
Some supplement blends, meanwhile, claim to work by combining ingredients – bacopa, cat's claw, huperzia serrata and oat straw in the case of Alpha Brain, for example – that have some support for boosting cognition and other areas of nervous system health. One 2014 study in Frontiers in Aging Neuroscience, suggested that huperzia serrata, which is used in China to fight Alzheimer's disease, may help slow cell death and protect against (or slow the progression of) neurodegenerative diseases. The Alpha Brain product itself has also been studied in a company-funded small randomized controlled trial, which found Alpha Brain significantly improved verbal memory when compared to adults who took a placebo.
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.
Why? Just think for a moment how much visual, auditory, and sensory information you’re exposed to and required to process every day.  From constant background sounds to big city noise pollution, the phone ringing, artificial lighting, chemical-laden air fresheners circulating smells of fresh linen, electromagnetic fields piercing through your brain, the new procedure you have to learn at work, and a host of other sensory stimuli, the human brain has to organize and deal with this information all while keeping you upright and going. Although the brain has incredible skills and unimaginable capabilities, modern living creates unprecedented stress and sensory overload from all of the information that must be processed every single day.  Sensory overload has even been shown to cause irritability, anxiety, mood swings, depression, ADHD, fibromyalgia, PTSD and chronic fatigue syndrome. The ability of your brain to continue learning, processing, and forming new neural connections is key to maintaining optimal brain health and longevity.
The reality is that cognitive impairment and dementia are also on the rise, and sometimes symptoms of forgetfulness and confusion are not so innocuous.  According to the Alzheimer’s Association, someone in the United States is diagnosed with Alzheimer’s disease every 66 seconds.  By the middle of this century, that is expected to grow to every 33 seconds.
As a result of her years of research in this area, Dr. Lisa proposes a variety of foods that lead to better cognitive functioning and those which, in contrast, minimize cognitive functioning. "The best four foods one can consume to boost brain power are fish, dark leafy green veggies, berries, and water," she explains. And the worst? "Fast food, processed foods and poor quality meat." 

A passionate singer, yogi, and vegan baker, you can usually count on Jessica to be writing songs, inventing recipes, or doing handstands. Most notably, Jessica is recognized (by her parents) for a 3 minute vocal solo at Carnegie Hall (at 13), by her friends for her amazing Raw Vegan Peanut Butter Chocolate Chip Cookie recipe, and also by her yogi friends for her recent mastery of Camel Pose. In all seriousness, Jessica is beyond excited to write for SnackNation, and to share her passion for health, wellness, and delicious foods.

But Baldino may have been overly modest. In 2002, researchers at Cambridge University gave 60 healthy young male volunteers a battery of standard cognitive tests. One group received modafinil, the other a placebo. The modafinil group performed better on several tasks, such as the "digit span" test, in which subjects are asked to repeat increasingly longer strings of numbers forwards, then backwards. They also did better in recognising repeated visual patterns and at a spatial-planning challenge known as the Tower of London task. (It's not nearly as fun as it sounds.) Writing in the journal Psychopharmacology, the study's authors said the results suggested that "modafinil offers significant potential as a cognitive enhancer".
In my last post, I talked about the idea that there is a resource that is necessary for self-control…I want to talk a little bit about the candidate for this resource, glucose. Could willpower fail because the brain is low on sugar? Let’s look at the numbers. A well-known statistic is that the brain, while only 2% of body weight, consumes 20% of the body’s energy. That sounds like the brain consumes a lot of calories, but if we assume a 2,400 calorie/day diet - only to make the division really easy - that’s 100 calories per hour on average, 20 of which, then, are being used by the brain. Every three minutes, then, the brain - which includes memory systems, the visual system, working memory, then emotion systems, and so on - consumes one (1) calorie. One. Yes, the brain is a greedy organ, but it’s important to keep its greediness in perspective… Suppose, for instance, that a brain in a person exerting their willpower - resisting eating brownies or what have you - used twice as many calories as a person not exerting willpower. That person would need an extra one third of a calorie per minute to make up the difference compared to someone not exerting willpower. Does exerting self control burn more calories?
And when it comes to your brain, it’s full of benefits, too. Coconut oil works as a natural anti-inflammatory, suppressing cells responsible for inflammation. It can help with memory loss as you age and destroy bad bacteria that hangs out in your gut. (5) Get your dose of coconut oil in this Baked Grouper with Coconut Cilantro Sauce or Coconut Crust Pizza.
There are many books about nutrition and cognitive functions. The authors ground their nutrition protocol on what humans ate during the paleolithic era. Often these authors contradict each other. For some, we were better hunters than gatherers so we ate mostly meat. For others, we were better gatherers and ate primarily nuts, plants, fruits. Others advance our digestive system can’t tolerate grains because it was a modern invention of the first agricultural revolution (about 10,000 years ago).
Farah told me: "These drugs will definitely help some technically normal people - that is, people who don't meet the diagnostic criteria for ADHD or any kind of cognitive impairment." But, she emphasised, "They will help people in the lower end of the ability range more than in the higher end." One explanation for this phenomenon might be that the more adept you are at a given task, the less room you have to improve. Farah has a hunch that there may be another reason that existing drugs - so far, at least - don't offer as much help to people with greater intellectual abilities. Drugs like Ritalin and Adderall work in part by elevating the amount of dopamine in the brain. Dopamine is something you want just enough of: too little, and you may not be as alert and motivated as you need to be; too much, and you may feel overstimulated. Neuroscientists have discovered that some people have a gene that leads the brain to break down dopamine faster, leaving less of it available; such people are generally a little worse at certain cognitive tasks. People with more available dopamine are generally somewhat better at the same tasks. It makes sense, then, that people with naturally low dopamine would benefit more from an artificial boost.
The benefit of sequential analysis here is being able to stop early, conserving pills, and letting me test another dosage: if I see another pattern of initial benefits followed by decline, I can then try cutting the dose by taking one pill every 3 days; or, if there is a benefit and no decline, then I can try tweaking the dose up a bit (maybe 3 days out of 5?). Since I don’t have a good idea what dose I want and the optimal dose seems like it could be valuable (and the wrong dose harmful!), I can’t afford to spend a lot of time on a single definitive experiment.
At this point, I began thinking about what I was doing. Black-market Adderall is fairly expensive; $4-10 a pill vs prescription prices which run more like $60 for 120 20mg pills. It would be a bad idea to become a fan without being quite sure that it is delivering bang for the buck. Now, why the piracetam mix as the placebo as opposed to my other available powder, creatine powder, which has much smaller mental effects? Because the question for me is not whether the Adderall works (I am quite sure that the amphetamines have effects!) but whether it works better for me than my cheap legal standbys (piracetam & caffeine)? (Does Adderall have marginal advantage for me?) Hence, I want to know whether Adderall is better than my piracetam mix. People frequently underestimate the power of placebo effects, so it’s worth testing. (Unfortunately, it seems that there is experimental evidence that people on Adderall know they are on Adderall and also believe they have improved performance, when they do not5. So the blind testing does not buy me as much as it could.)
Age discrimination is alive and well throughout the whole of the UK, a piece of legislation does nothing to ensure that people over the age of 50 get a fair crack of the whip when applying for employment, Employers dont need to give a reason for not employing a person over 50 all they need to say is that theyre unsuitable opr a more suitable candidate got the position, albeit they are usually younger!

One might suggest just going to the gym or doing other activities which may increase endogenous testosterone secretion. This would be unsatisfying to me as it introduces confounds: the exercise may be doing all the work in any observed effect, and certainly can’t be blinded. And blinding is especially important because the 2011 review discusses how some studies report that the famed influence of testosterone on aggression (eg. Wedrifid’s anecdote above) is a placebo effect caused by the folk wisdom that testosterone causes aggression & rage!
The evidence? A 2012 study in Greece found it can boost cognitive function in adults with mild cognitive impairment (MCI), a type of disorder marked by forgetfulness and problems with language, judgement, or planning that are more severe than average “senior moments,” but are not serious enough to be diagnosed as dementia. In some people, MCI will progress into dementia.
Took full pill at 10:21 PM when I started feeling a bit tired. Around 11:30, I noticed my head feeling fuzzy but my reading seemed to still be up to snuff. I would eventually finish the science book around 9 AM the next day, taking some very long breaks to walk the dog, write some poems, write a program, do Mnemosyne review (memory performance: subjectively below average, but not as bad as I would have expected from staying up all night), and some other things. Around 4 AM, I reflected that I felt much as I had during my nightwatch job at the same hour of the day - except I had switched sleep schedules for the job. The tiredness continued to build and my willpower weakened so the morning wasn’t as productive as it could have been - but my actual performance when I could be bothered was still pretty normal. That struck me as kind of interesting that I can feel very tired and not act tired, in line with the anecdotes.

This was so unexpected that I wondered if I had somehow accidentally put the magnesium pills into the placebo pill baggie or had swapped values while typing up the data into a spreadsheet, and checked into that. The spreadsheet accorded with the log above, which rules out data entry mistakes; and looking over the log, I discovered that some earlier slip-ups were able to rule out the pill-swap: I had carelessly put in some placebo pills made using rice, in order to get rid of them, and that led to me being unblinded twice before I became irritated enough to pick them all out of the bag of placebos - but how could that happen if I had swapped the groups of pills?
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.
It’s also loaded with vitamin C — in fact, just one cup provides you with 150 percent of your recommended daily intake. Its high-fiber levels mean that you’ll feel full quickly, too. If you’ve only chowed down on overcooked, tasteless broccoli, you’ll love my Crockpot Beef and Broccoli, Creamy Broccoli Soup and Broccoli Pesto Dip — they’ll turn you into a broccoli lover fast!
It wasn't always helpful, but it does work sometimes. The first two days gave me stomach and head pain, so I began to test with taking before or after food, and with or without food. The bottle says to take before food, but I preferred taking this with food, more food is better. This doesn't go well in the stomach with something like chocolate, so take this with something like bread or a meal. More importantly, stay very hydrated unless you want a headache, these pills are very hydro-demanding. The pills also work better if you get your blood moving, just a short walk is fine. Energy drinks and coffee go very well with these, as I had a very clear minded experience when taking these with a Monster Java, it was like a cool breeze blowing away the mental fog.
The effect? 3 or 4 weeks later, I’m not sure. When I began putting all of my nootropic powders into pill-form, I put half a lithium pill in each, and nevertheless ran out of lithium fairly quickly (3kg of piracetam makes for >4000 OO-size pills); those capsules were buried at the bottom of the bucket under lithium-less pills. So I suddenly went cold-turkey on lithium. Reflecting on the past 2 weeks, I seem to have been less optimistic and productive, with items now lingering on my To-Do list which I didn’t expect to. An effect? Possibly.
One idea I’ve been musing about is the connections between IQ, Conscientiousness, and testosterone. IQ and Conscientiousness do not correlate to a remarkable degree - even though one would expect IQ to at least somewhat enable a long-term perspective, self-discipline, metacognition, etc! There are indications in studies of gifted youth that they have lower testosterone levels. The studies I’ve read on testosterone indicate no improvements to raw ability. So, could there be a self-sabotaging aspect to human intelligence whereby greater intelligence depends on lack of testosterone, but this same lack also holds back Conscientiousness (despite one’s expectation that intelligence would produce greater self-discipline and planning), undermining the utility of greater intelligence? Could cases of high IQ types who suddenly stop slacking and accomplish great things sometimes be due to changes in testosterone? Studies on the correlations between IQ, testosterone, Conscientiousness, and various measures of accomplishment are confusing and don’t always support this theory, but it’s an idea to keep in mind.
Nootropic (new-tro-pik) is the term for supplements, also known as smart drugs, that improve brain function. They can be food substances like phenethylamine and L-Theanine, found in chocolate and green tea, respectively. Nootropics also include extracted and purified components of medicinal plants, as well as substances synthesized from chemical precursors, such as piracetam, the world's first official nootropic (piracetam was created in 1964 in Belgium by a team of scientists whose leader, Dr. Corneliu E. Giurgea, coined the term). Since then piracetam has been widely used as a cognitive enhancer and to treat neurological diseases like Alzheimer's.
…Four subjects correctly stated when they received nicotine, five subjects were unsure, and the remaining two stated incorrectly which treatment they received on each occasion of testing. These numbers are sufficiently close to chance expectation that even the four subjects whose statements corresponded to the treatments received may have been guessing.
These little chemicals prompt the immune system to kick in and fight back against the stress through inflammation, as though stress is an infection. While inflammation helps protect us against illnesses and repairs the body when you do something like cut yourself, chronic inflammation is a different animal. It’s been linked to autoimmune diseases like multiple sclerosis, anxiety, high blood pressure and more. (2)
Nootropics—the name given to a broad class of so-called "cognitive-enhancing" drugs—are all the rage in Silicon Valley these days. Programmers like nootropics because they’re said to increase productivity and sharpen focus without the intensity or side effects of a prescription drug like Adderall or modafinil. Some users mix their own nootropics using big bins of powders, purchased off the Internet or in supplement stores. And some take pre-made "stacks" that are designed to produce specific effects.

It is important that this type of approach is discussed with a qualified health professional, such as a registered nutritional therapist, to ensure it is an appropriate strategy for you, as well as to help you avoid missing out on vital nutrients, whilst eliminating certain foods. They can also provide advice on improving your longer term health, which over time may allow for foods to be reintroduced without negative symptoms occurring.


So where did the idea of Blue Monday come from? The concept of Blue Monday was originally coined by Dr Cliff Arnall in 2005 and distributed by the PR company Sky Travel. It has now become an annual event and can fall on either the third or the fourth Monday of January, using Dr Cliff Arnall’s original mathematical equation that measures a combination of factors such as weather, potential debt post-Christmas, the amount of time since Christmas, potential failure of New Year resolutions and motivation levels, that apparently conspire to make the date the gloomiest of the year.
There are many studies that suggest that Creatine helps in treating cognitive decline in individuals when combined with other therapies. It also helps people suffering from Parkinsons and Huntingtons disease. Though there are minimal side effects associated with creatine, pretty much like any nootropic, it is not  absolutely free of side-effects. An overdose of creatine can lead to gastrointestinal issues, weight gain, stress and anxiety.

Your brain is essentially a network of billions of neurons connected by synapses. These neurons communicate and work together through chemicals known as neurotransmitters. When neurotransmitters are able to send signals more efficiently, you experience improved concentration, better memory, mood elevation, increased processing ability for mental work, and longer attention spans.
Methylfolate and methyl B12 work together to control methylation reactions that repair your DNA and regenerate brain cells.[11] The methylated forms are particularly important brain food — you have about three times as much methylfolate in your cerebrospinal fluid (the fluid around your brain and spine) as you do in your blood,[12] where it’s working tirelessly to maintain your nerve connections and repair DNA mutations.[13] Folate and B12 are particularly important for brain anti-aging.[14]
Notice that poor diet is not on the list. They recommend active treatment of hypertension, more childhood education, exercise, maintaining social engagement, reducing smoking, and management of hearing loss, depression, diabetes, and obesity. They do not recommend specific dietary interventions or supplements. They estimate that lifestyle interventions “might have the potential to delay or prevent a third of dementia cases.”
Nicotine has been shown to improve working memory, and research has also demonstrated that oral consumption of nicotine enhances memory consolidation in perceptual learning by enhancing the efficacy of nicotinic acetylcholine receptors and thereby enhancing the overall cholinergic system, which modulates memory formation. In other words, nicotine consumption improves the efficiency of acetylcholine (a neurotransmitter) receptors and, thus, improves the part of the nervous system that regulates healthy memory function. Some research also indicates that psychiatric populations suffering from cognitive deficits (such as patients suffering from schizophrenia) may enjoy even greater neuroprotection from nicotine consumption than healthy individuals. You may be concerned about using nicotine given its potential as an addictive substance. Well, nicotine plays a dual role in the brain by simultaneously promoting addiction and enhancing cognition. In fact, the processes are closely linked through the pathways by which they work. That means that when it comes to dosing nicotine, it’s all about moderation. Because nicotine can be easily abused and has high addictive potential, when using nicotine for cognitive enhancement, you must be precise with dosage and conscious of the amount you use. Studies have shown that moderate doses of nicotine typically produce cognitive enhancement, but very high doses can actually impair cognitive performance. A moderate dose would look something like 2-4 milligrams administered over 20-30 minutes, a dose easily available in the form of nicotine gum or spray. Later in this article, I’ll fill you in on my own personal dosage and use of nicotine.
I take my piracetam in the form of capped pills consisting (in descending order) of piracetam, choline bitartrate, anhydrous caffeine, and l-tyrosine. On 8 December 2012, I happened to run out of them and couldn’t fetch more from my stock until 27 December. This forms a sort of (non-randomized, non-blind) short natural experiment: did my daily 1-5 mood/productivity ratings fall during 8-27 December compared to November 2012 & January 2013? The graphed data29 suggests to me a decline:
Dr. Mosconi: I love apples. When I’m at the office though, I’ll bring homemade trail mix [made with] higher quality dried fruit, nuts and seeds. [It's] packed with brain-essential nutrients that come from goji berries, Brazil nuts, walnuts, cacao nibs, pistachios, hemp hearts and  more. Plus, I drink plenty of rose water throughout the day, which is very anti-inflammatory.

That study is also interesting for finding benefits to chronic piracetam+choline supplementation in the mice, which seems connected to a Russian study which reportedly found that piracetam (among other more obscure nootropics) increased secretion of BDNF in mice. See also Drug heuristics on a study involving choline supplementation in pregnant rats.↩


The difference in standard deviations is not, from a theoretical perspective, all that strange a phenomenon: at the very beginning of this page, I covered some basic principles of nootropics and mentioned how many stimulants or supplements follow a inverted U-curve where too much or too little lead to poorer performance (ironically, one of the examples in Kruschke 2012 was a smart drug which did not affect means but increased standard deviations).

Lebowitz says that if you're purchasing supplements to improve your brain power, you're probably wasting your money. "There is nothing you can buy at your local health food store that will improve your thinking skills," Lebowitz says. So that turmeric latte you've been drinking everyday has no additional brain benefits compared to a regular cup of java.
The Neurohacker Collective is a group of scientists, academics, and creatives who, among other things, sell nootropics. One of its premier products is Qualia Original Stack (OS), which has 41 ingredients. The large print says it improves focus, mood, and energy within 30 minutes and “supports long-term brain health.” A 22-dose supply costs $129. Such stacks operate on the idea that synergies among ingredients yield additional benefits.
Herbs and plants have been used for cognitive enhancement for at least 5,000 years in Indian and Chinese medicine, long before the first synthetic nootropic was created. The practice of Indian Ayurvedic medicine includes the use of a group of nootropic plants known as Medhya Rasayana, the four primary plants of which are Mandukaparni, Yastimadhu, Duduchi and Shankhapushpi, though other lesser known plants are also used. One of the most common supplements in Ayurvedic medicine is Brahmi, known scientifically as “Bacopa monnieri” or “B. monnieri “ and more commonly as water hyssop, Thyme-leaved Gratiola, herb of grace or Indian pennywort. It is named after Lord Brahma, the creator God and originator of Ayurveda, and has been used for centuries to treat disorders ranging from pain and epilepsy to inflammation and memory dysfunction. The exact mechanism behind its action is not fully understood, but it is believed to promote antioxidant activity as well as protect neurons in the prefrontal cortex, hippocampus and corpus striatum against cytotoxicity and DNA damage associated with Alzheimer’s. The prefrontal cortex is critical in rational, social and personality behavior, the hippocampus is believed to be the seat of memory and the autonomic nervous system and the striatum play a role in the reward system of action, so the protection Brahmi provides is extremely helpful in preventing the degeneration of many important cognitive faculties. An effective dose ranges from 300 to 450 mg per day. Winter cherry (ashwagandha) is another well-known Ayurvedic supplement that can promote improved cognitive development, memory and intelligence and reduce the effects of neurodegenerative diseases such as Parkinson’s, Huntington’s and Alzheimer’s. The optimal dose is 6,000 mg per day divided into three 2,000 mg doses. Aloeweed (shankhpushpi) is also used in Ayurvedic medicine to improve memory and intellect as well as treat hypertension, epilepsy and diabetes. Effective doses for most neuroenhancing benefits range as high as 40 g per day.

In my SkepDoc column in Skeptic magazine (text available online) I reviewed the video series “Awakening from Alzheimer’s,” in which a journalist interviews numerous “experts” and claims that Alzheimer’s is for the most part preventable and can be reversed in 9 out of 10 patients! The recommendations of those “experts” are all over the map. There is nothing even remotely approaching a scientific consensus. They claim the main cause of Alzheimer’s is everything from gluten to obesity to lack of sleep to chronic Lyme disease to toxins spewed by “leaky gut” syndrome. They claim to have reversed Alzheimer’s with a wide variety of treatments: everything from coconut oil to a ketogenic diet to probiotics to strenuous exercise to various long lists of dietary supplements to psychological interventions that are considered successful if they make patients cry. There is no satisfactory evidence to support any of their claims.

With a lack of reviews and a formulation containing some questionable ingredients that we could not find to benefit consumers, together with the possibility of the product being sub-standard, we placed this product in our # 4 ranking. Its redeeming features however, include the fact that they use all-natural ingredients plus, the price is cheap, if you are into taking a risk about the quality of the product.
(On a side note, I think I understand now why modafinil doesn’t lead to a Beggars in Spain scenario; BiS includes massive IQ and motivation boosts as part of the Sleepless modification. Just adding 8 hours a day doesn’t do the world-changing trick, no more than some researchers living to 90 and others to 60 has lead to the former taking over. If everyone were suddenly granted the ability to never need sleep, many of them would have no idea what to do with the extra 8 or 9 hours and might well be destroyed by the gift; it takes a lot of motivation to make good use of the time, and if one cannot, then it is a curse akin to the stories of immortals who yearn for death - they yearn because life is not a blessing to them, though that is a fact more about them than life.)
On the other hand, sometimes you’ll feel a great cognitive boost as soon as you take a pill. That can be a good thing or a bad thing. I find, for example, that modafinil makes you more of what you already are. That means if you are already kind of a dick and you take modafinil, you might act like a really big dick and regret it. It certainly happened to me! I like to think that I’ve done enough hacking of my brain that I’ve gotten over that programming… and that when I use nootropics they help me help people.
Reason: Besides keeping cells intact, this membrane performs vital functions. These actions include moving nutrients into cells and pumping waste products out of them. Investigators in one study determined that phosphatidyl serine shaved 12 years off the normal expected decline. This result was present in specific aspects of memory performance. Phosphatidyl serine is shown in studies to boost cognitive function. This occurs by increasing communication between brain cells. Those who took 100 mg of phosphatidyl serine three times a day, with meals for 12 weeks scored 30% higher on memory and learning tests.

In fact, many nerve gas agents act similarly to Huperzia serrata by blocking the enzyme that breaks down acetylcholine. But research has shown that in smaller doses, Huperzine A, the extract of Huperzia serrata used in nootropics, would likely offer some protection against damage from nerve agents. That the same substance can act as a nerve agent, protect against nerve agents, and give you crazy dreams, underscores how important it is to stay within the recommended doses.

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".

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.
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.
However, despite these apparent good results, it’s recommended that you don’t run to the pharmacy just yet. The long term effects of taking Modafinil haven’t been studied conclusively or in-depth yet; to the contrary and in direct opposition to the many claims that Modafinil is completely safe, 50% of modafinil users report a number of short term side effects, such as mild to severe headaches, insomnia, nausea, anxiety, nervousness, hypertension, decreased appetite, and weight loss.
as scientific papers become much more accessible online due to Open Access, digitization by publishers, and cheap hosting for pirates, the available knowledge about nootropics increases drastically. This reduces the perceived risk by users, and enables them to educate themselves and make much more sophisticated estimates of risk and side-effects and benefits. (Take my modafinil page: in 1997, how could an average person get their hands on any of the papers available up to that point? Or get detailed info like the FDA’s prescribing guide? Even assuming they had a computer & Internet?)
Blinding stymied me for a few months since the nasty taste was unmistakable and I couldn’t think of any gums with a similar flavor to serve as placebo. (The nasty taste does not seem to be due to the nicotine despite what one might expect; Vaniver plausibly suggested the bad taste might be intended to prevent over-consumption, but nothing in the Habitrol ingredient list seemed to be noted for its bad taste, and a number of ingredients were sweetening sugars of various sorts. So I couldn’t simply flavor some gum.)
If you want to focus on boosting your brain power, Lebowitz says you should primarily focus on improving your cardiovascular health, which is "the key to good thinking." For example, high blood pressure and cholesterol, which raise the risk of heart disease, can cause arteries to harden, which can decrease blood flow to the brain. The brain relies on blood to function normally.
Panax ginseng – A review by the Cochrane Collaboration concluded that "there is a lack of convincing evidence to show a cognitive enhancing effect of Panax ginseng in healthy participants and no high quality evidence about its efficacy in patients with dementia."[36] According to the National Center for Complementary and Integrative Health, "[a]lthough Asian ginseng has been widely studied for a variety of uses, research results to date do not conclusively support health claims associated with the herb."[37]
