Alex's sense of who uses stimulants for so-called "non-medical" purposes is borne out by two dozen or so scientific studies. In 2005 a team led by Sean Esteban McCabe, a professor at the University of Michigan, reported that in the previous year 4.1% of American undergraduates had taken prescription stimulants for off-label use - at one school the figure was 25%, while a 2002 study at a small college found that more than 35% of the students had used prescription stimulants non-medically in the previous year.
Pop this pill and improve your memory. Swallow that one and reduce your cognitive decline. We see ads for such products all the time and I suspect they will increase as the baby boomers reach senior citizenhood. The most popular brain boosting supplements are fish oil pills and they are also probably the best studied ones. The results are not encouraging. When all the studies are pooled, we are left with the possibility of a barely significant improvement in recalling lists of words soon after they have been learned, but the effect does not last. Extracts of the ginkgo biloba tree are also popular, and here the prospects are even dimmer. There is no impact on memory, despite claims of increased circulation in the brain. And ginkgo can interfere with the action of anticoagulants and has also been shown to be an animal carcinogen.
Still, putting unregulated brain drugs into my system feels significantly scarier than downing a latte or a Red Bull—not least because the scientific research on nootropics’ long-term effects is still so thin. One 2014 study found that Ritalin, modafinil, ampakines, and other similar stimulants could eventually reduce the “plasticity” of some of the brain’s neural networks by providing them with too much dopamine, glutamate and norepinephrine, and potentially cause long-term harm in young people whose brains were still developing. (In fact, in young people, the researchers wrote, these stimulants could actually have the opposite effect the makers intended: “Healthy individuals run the risk of pushing themselves beyond optimal levels into hyperdopaminergic and hypernoradrenergic states, thus vitiating the very behaviors they are striving to improve.”) But the researchers found no evidence that normal doses of these drugs were harmful when taken by adults.
Qualia Mind, meanwhile, combines more than two dozen ingredients that may support brain and nervous system function – and even empathy, the company claims – including vitamins B, C and D, artichoke stem and leaf extract, taurine and a concentrated caffeine powder. A 2014 review of research on vitamin C, for one, suggests it may help protect against cognitive decline, while most of the research on artichoke extract seems to point to its benefits to other organs like the liver and heart. A small company-lead pilot study on the product found users experienced improvements in reasoning, memory, verbal ability and concentration five days after beginning Qualia Mind.
True Focus offers several very positive elements. The ingredients are excellent quality and all natural and without side effects. We like the fact they offer a product that is both vegan and vegetarian friendly, as well as being gluten, soy and dairy free. This allows many consumers to experience the benefits of this product. The fact they do not offer a clear money-back guarantee, we felt, placed them in a weaker position. Moreover, the lack of multi-purchase price deals left us feeling that this was slightly expensive, as with no options to reduce the cost per bottle, consumers will be stuck paying slightly more for each bottle.
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.
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.
Cocoa flavanols (CF) positively influence physiological processes in ways which suggest that their consumption may improve aspects of cognitive function. This study investigated the acute cognitive and subjective effects of CF consumption during sustained mental demand. In this randomized, controlled, double-blinded, balanced, three period crossover trial 30 healthy adults consumed drinks containing 520 mg, 994 mg CF and a matched control, with a 3-day washout between drinks. Assessments included the state anxiety inventory and repeated 10-min cycles of a Cognitive Demand Battery comprising of two serial subtraction tasks (Serial Threes and Serial Sevens), a Rapid Visual Information Processing (RVIP) task and a mental fatigue scale, over the course of 1 h. Consumption of both 520 mg and 994 mg CF significantly improved Serial Threes performance. The 994 mg CF beverage significantly speeded RVIP responses but also resulted in more errors during Serial Sevens. Increases in self-reported mental fatigue were significantly attenuated by the consumption of the 520 mg CF beverage only. This is the first report of acute cognitive improvements following CF consumption in healthy adults. While the mechanisms underlying the effects are unknown they may be related to known effects of CF on endothelial function and blood flow.
The principal metric would be mood, however defined. Zeo’s web interface & data export includes a field for Day Feel, which is a rating 1-5 of general mood & quality of day. I can record a similar metric at the end of each day. 1-5 might be a little crude even with a year of data, so a more sophisticated measure might be in order. The first mood study is paywalled so I’m not sure what they used, but Shiotsuki 2008 used State-Trait of Anxiety Inventory (STAI) and Profiles of Mood States Test (POMS). The full POMS sounds too long to use daily, but the Brief POMS might work. In the original 1987 paper A brief POMS measure of distress for cancer patients, patients answering this questionnaire had a mean total mean of 10.43 (standard deviation 8.87). Is this the best way to measure mood? I’ve asked Seth Roberts; he suggested using a 0-100 scale, but personally, there’s no way I can assess my mood on 0-100. My mood is sufficiently stable (to me) that 0-5 is asking a bit much, even.
…It is without activity in man! Certainly not for the lack of trying, as some of the dosage trials that are tucked away in the literature (as abstracted in the Qualitative Comments given above) are pretty heavy duty. Actually, I truly doubt that all of the experimenters used exactly that phrase, No effects, but it is patently obvious that no effects were found. It happened to be the phrase I had used in my own notes.
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.
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.
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.
Whole grains, which you digest slowly, provide fuel for your brain. (Although your brain accounts for only 3 percent of your total body weight, it uses 20 percent of energy.) Rich sources include brown rice, whole wheat bread, quinoa, bran flakes, oats, and barley. According to Science Daily, brain food containing whole grains can boost cardiovascular health, which in turn enhances the flow of blood to the brain. They contain more intact nutrients than processed white flour, including vitamin E, antioxidants, and fiber. When these work together to increase blood flow, the integrity of brain cells is better preserved. To keep your brain sharp, go beyond your diet and incorporate these healthy brain-boosting habits into your routine.
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.
Like everything else in your body, the brain cannot work without energy. The ability to concentrate and focus comes from an adequate, steady supply of energy - in the form of glucose in our blood to the brain. Achieve this by choosing wholegrains with a low-GI, which release glucose slowly into the bloodstream, keeping you mentally alert throughout the day. Opt for 'brown' wholegrain cereals, granary bread, rice and pasta.
Some people aren’t satisfied with a single supplement—the most devoted self-improvers buy a variety of different compounds online and create their own custom regimens, which they call “stacks.” According to Kaleigh Rogers, writing in Vice last year, companies will now take their customers’ genetic data from 23andMe or another source and use it to recommend the right combinations of smart drugs to optimize each individual’s abilities. The problem with this practice is that there’s no evidence the practice works. (And remember, the FDA doesn’t regulate supplements.) Find out the 9 best foods to boost your brain health.
To thwart the rise of non-prescription nootropics, opponents may rally for increased regulation; however, at present, there is insufficient research available to support that non-prescription nootropics pose a danger to public health. Prescription nootropics, such as Ritalin, are already regulated. Further, these drugs have a proven beneficial treatment purpose for intended users.
Research in animals shows that blueberries may help protect the brain from the damage caused by free radicals and may reduce the effects of age-related conditions such as Alzheimer's disease or dementia. Studies also show that diets rich in blueberries improved both the learning and muscle function of aging rats, making them mentally equal to much younger rats.
The desire to improve cognitive functioning has probably existed since the dawn of human consciousness. Throughout our evolution, increased mental agility has been associated with fitness and improved odds of survival and success. Although concoctions to stimulate brainpower have existed in Chinese and Indian medicine for hundreds of years, Western nootropics were not developed until 1964.
-Water [is also important]. Over 80% of the brain’s content is water. Every chemical reaction that takes place in the brain needs water, especially energy production. The brain is so sensitive to dehydration that even a minimal loss of water can cause symptoms like brain fog, fatigue, dizziness, confusion and, more importantly, brain shrinkage. The longevity and well-being of your brain are critically dependent upon consuming hard water. This refers to plain water that is high in minerals and natural electrolytes. Most people don’t realize that the water they’re drinking is not actually “water”.
Real extra virgin olive oil is truly a brain food. Thanks to the powerful antioxidants known as polyphenols that are found in the oil, including EVOO in your diet may not only improve learning and memory, but also reverse the age- and disease-related changes. (7) The oil also helps fight against ADDLs, proteins that are toxic to the brain and induce Alzheimer’s. (8)
Just like throughout pregnancy, nutritional needs after birth, especially if breastfeeding, are incredibly important. The healthier the diet, the easier it will be to sustain the energy needed to take care of a newborn. Research shows that a breastfeeding mother needs an extra 300-500 calories a day, from food that is rich in the right macro and micronutrients to nourish both mother and baby (3). For example, nutrients such as B vitamins have shown to be important in supporting the mother in ensuring she has enough energy to meet the demands of lactation (4). These nutrients can be found in green leafy vegetables, wholegrains and good sources of animal protein.
And in his followup work, An opportunity cost model of subjective effort and task performance (discussion). Kurzban seems to have successfully refuted the blood-glucose theory, with few dissenters from commenting researchers. The more recent opinion seems to be that the sugar interventions serve more as a reward-signal indicating more effort is a good idea, not refueling the engine of the brain (which would seem to fit well with research on procrastination).↩
It makes no sense to ban the use of neuroenhancers. Too many people are already taking them, and the users tend to be educated and privileged people who proceed with just enough caution to avoid getting into trouble. Besides, Anjan Chatterjee is right that there is an apt analogy with plastic surgery. In a consumer society like ours, if people are properly informed about the risks and benefits of neuroenhancers, they can make their own choices about how to alter their minds, just as they can make their own decisions about shaping their bodies.
The chemical Huperzine-A (Examine.com) is extracted from a moss. It is an acetylcholinesterase inhibitor (instead of forcing out more acetylcholine like the -racetams, it prevents acetylcholine from breaking down). My experience report: One for the null hypothesis files - Huperzine-A did nothing for me. Unlike piracetam or fish oil, after a full bottle (Source Naturals, 120 pills at 200μg each), I noticed no side-effects, no mental improvements of any kind, and no changes in DNB scores from straight Huperzine-A.
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."
Took pill around 6 PM; I had a very long drive to and from an airport ahead of me, ideal for Adderall. In case it was Adderall, I chewed up the pill - by making it absorb faster, more of the effect would be there when I needed it, during driving, and not lingering in my system past midnight. Was it? I didn’t notice any change in my pulse, I yawned several times on the way back, my conversation was not more voluminous than usual. I did stay up later than usual, but that’s fully explained by walking to get ice cream. All in all, my best guess was that the pill was placebo, and I feel fairly confident but not hugely confident that it was placebo. I’d give it ~70%. And checking the next morning… I was right! Finally.
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."
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,  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.
The advantage of adrafinil is that it is legal & over-the-counter in the USA, so one removes the small legal risk of ordering & possessing modafinil without a prescription, and the retailers may be more reliable because they are not operating in a niche of dubious legality. Based on comments from others, the liver problem may have been overblown, and modafinil vendors post-2012 seem to have become more unstable, so I may give adrafinil (from another source than Antiaging Central) a shot when my modafinil/armodafinil run out.
I’ve tried a few different ways of taking my nootropics—in the morning, in the afternoon, in addition to coffee, as a replacement for coffee—and so far, the effects I'm feeling are much more subtle than I expected. There’s no sweaty-palmed intensity, no eight-hour uninterruptible work sprints, and none of the hyperactivity you’d associate with a caffeine high. It’s just a sensation of being a little amped up, and of being slightly less distracted than normal.
But according to Professor David Weinshenker of Emory University, most people who take Provigil do not report euphoria or even a level of stimulation close to the effects of caffeine. For Weinshenker, the addiction potential of Provigil is limited, and it’s used in various treatment contexts. Provigil may be an effective medication therapy for depression, ADHD, autism and other disorders.
I have a needle phobia, so injections are right out; but from the images I have found, it looks like testosterone enanthate gels using DMSO resemble other gels like Vaseline. This suggests an easy experimental procedure: spoon an appropriate dose of testosterone gel into one opaque jar, spoon some Vaseline gel into another, and pick one randomly to apply while not looking. If one gel evaporates but the other doesn’t, or they have some other difference in behavior, the procedure can be expanded to something like and then half an hour later, take a shower to remove all visible traces of the gel. Testosterone itself has a fairly short half-life of 2-4 hours, but the gel or effects might linger. (Injections apparently operate on a time-scale of weeks; I’m not clear on whether this is because the oil takes that long to be absorbed by surrounding materials or something else.) Experimental design will depend on the specifics of the obtained substance. As a controlled substance (Schedule III in the US), supplies will be hard to obtain; I may have to resort to the Silk Road.
But before you dismiss the diet-brain connection as mere conjecture, keep in mind that study after study has found a relationship between what we put in our mouths and how well we can perform important thinking and memory tasks. While certain nutrients may specifically assist brain function, there is also the totality of our diets to consider. One recent U.K. study found that a diet high in saturated fat actually caused damage to neurons that control energy and appetite in mice. And several well-regarded studies have shown that meal timing is an important predictor of performance. For example, research shows that eating breakfast can improve the memory and acquisition skills of schoolchildren.
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:
We felt that the price for this product was OK but were concerned about how cheap it was on some websites. Our experience suggests that this could reflect the standard of the product, it could be that the quality of ingredients is poor and the dosage low so that they can price cut, however, this leaves consumers having to take more to reach the same level as other products. This can lead to all sorts of issues regarding overdosing, so for these reasons, until further testing can be carried out, we could not place this higher on our score board.
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.
(I was more than a little nonplussed when the mushroom seller included a little pamphlet educating one about how papaya leaves can cure cancer, and how I’m shortening my life by decades by not eating many raw fruits & vegetables. There were some studies cited, but usually for points disconnected from any actual curing or longevity-inducing results.)
I’ve spent over a million dollars hacking my own biology. The lion’s share has gone to making my brain produce as much energy as it can. I even wrote a book, Head Strong, about neurofeedback, oxygen deprivation, supplements, deeper sleep, meditation, cold exposure, and about a dozen other brain hacks, and how you can use them to make your brain stronger than you thought possible.
Methylphenidate – a benzylpiperidine that had cognitive effects (e.g., working memory, episodic memory, and inhibitory control, aspects of attention, and planning latency) in healthy people. It also may improve task saliency and performance on tedious tasks. At above optimal doses, methylphenidate had off–target effects that decreased learning.
