If you’re a coffee or tea drinker, keep sipping: Caffeine may help protect against age-related cognitive decline. “Studies have indicated that caffeine—for example, roughly 500 milligrams daily, the equivalent of about five cups of coffee—may help stave off memory issues in humans,” says Bruce Citron, PhD, a neuroscientist at Bay Pines VA Healthcare System and the USF Morsani College of Medicine in Florida. (Experts warn against taking caffeine supplements, which flood your body with a lot of caffeine all at once.)

Nootroo and Nootrobox are two San Francisco nootropics startups that launched last year. Their founders come from the tech scene and their products are squarely aimed at the tech crowd seeking the convenience of not having to build their own combinations. Each claims big-name Silicon Valley entrepreneurs and investors among their users, though neither will name them.
Over the years, science has looked into the validity of this date being the most blue of all dates, however there is little evidence to prove this. There is some research that suggests how weekends are a time when people generally feel happier and less anxious, mostly for those that work full-time Monday-Friday, however there is little difference with subjective mood for other days of the week. Some charities such as MIND, have even said that Blue Monday, which is used mainly as a marketing tool to sell products and stories, can also be dangerously misleading and have even set up the hashtag #BlueAnyDay to help dispel the myth of this date.The idea that as a population we are more likely to feel down on the third of fourth Monday of the year can not only trivialise depression as a medical illness that can be life threatening but can also affect those that live with depression and know too well that feelings associated to this illness are not dictated by a single date in the diary.

Brain Pill™ combines the most powerful, clinically proven ingredients on the forefront of brain productivity and memory research. Each of our carefully selected ingredients is potent and effective on its own, but together, our research goal was to create far and away the ultimate synergistic combination for enhancing mental clarity, alertness and overall brain function.

Our #5 pick is BriteSmart which has a long list of ingredients, which look good on the bottle, but when we actually visited each one, we were left wondering about why some of them had been included. We did like the fact that it contained Vinpocetine and Huperzine A. We felt that this was a good product, but missing some key ingredients such as a supportive vitamin blend.
2ml is supposed to translate to 24mg, which is a big dose. I do not believe any of the commercial patches go much past that. I asked Wedrifid, whose notes inspired my initial interest, and he was taking perhaps 2-4mg, and expressed astonishment that I might be taking 24mg. (2mg is in line with what I am told by another person - that 2mg was so much that they actually felt a little sick. On the other hand, in one study, the subjects could not reliably distinguish between 1mg and placebo25.) 24mg is particularly troubling in that I weigh ~68kg, and nicotine poisoning and the nicotine LD50 start, for me, at around 68mg of nicotine. (I reflected that the entire jar could be a useful murder weapon, although nicotine presumably would be caught in an autopsy’s toxicology screen; I later learned nicotine was an infamous weapon in the 1800s before any test was developed. It doesn’t seem used anymore, but there are still fatal accidents due to dissolved nicotine.) The upper end of the range, 10mg/kg or 680mg for me, is calculated based on experienced smokers. Something is wrong here - I can’t see why I would have nicotine tolerance comparable to a hardened smoker, inasmuch as my maximum prior exposure was second-hand smoke once in a blue moon. More likely is that either the syringe is misleading me or the seller NicVape sold me something more dilute than 12mg/ml. (I am sure that it’s not simply plain water; when I mix the drops with regular water, I can feel the propylene glycol burning as it goes down.) I would rather not accuse an established and apparently well-liked supplier of fraud, nor would I like to simply shrug and say I have a mysterious tolerance and must experiment with doses closer to the LD50, so the most likely problem is a problem with the syringe. The next day I altered the procedure to sucking up 8ml, squirting out enough fluid to move the meniscus down to 7ml, and then ejecting the rest back into the container. The result was another mild clean stimulation comparable to the previous 1ml days. The next step is to try a completely different measuring device, which doesn’t change either.
Choline is very important for cognitive function because it is a precursor to Acteylcholine. Your body needs enough choline to convert into Acteylcholine to keep your brain healthy. For this reason, choline supplements are often considered great nootropics, even by themselves. CDP-Choline and Alpha GPC are the best sources for supplemental Choline.
I started with the 10g of Vitality Enhanced Blend, a sort of tan dust. Used 2 little-spoonfuls (dust tastes a fair bit like green/oolong tea dust) into the tea mug and then some boiling water. A minute of steeping and… bleh. Tastes sort of musty and sour. (I see why people recommended sweetening it with honey.) The effects? While I might’ve been more motivated - I hadn’t had caffeine that day and was a tad under the weather, a feeling which seemed to go away perhaps half an hour after starting - I can’t say I experienced any nausea or very noticeable effects. (At least the flavor is no longer quite so offensive.)
Broccoli is great source of vitamin K, which is known to enhance cognitive function and improve brainpower. Researchers have reported that because broccoli is high in compounds called glucosinolates, it can slow the breakdown of the neurotransmitter, acetylcholine, which we need for the central nervous system to perform properly and to keep our brains and our memories sharp. Low levels of acetylcholine are associated with Alzheimer's.
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.
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.↩
It's been widely reported that Silicon Valley entrepreneurs and college students turn to Adderall (without a prescription) to work late through the night. In fact, a 2012 study published in the Journal of American College Health, showed that roughly two-thirds of undergraduate students were offered prescription stimulants for non-medical purposes by senior year.
In this large population-based cohort, we saw consistent robust associations between cola consumption and low BMD in women. The consistency of pattern across cola types and after adjustment for potential confounding variables, including calcium intake, supports the likelihood that this is not due to displacement of milk or other healthy beverages in the diet. The major differences between cola and other carbonated beverages are caffeine, phosphoric acid, and cola extract. Although caffeine likely contributes to lower BMD, the result also observed for decaffeinated cola, the lack of difference in total caffeine intake across cola intake groups, and the lack of attenuation after adjustment for caffeine content suggest that caffeine does not explain these results. A deleterious effect of phosphoric acid has been proposed (26). Cola beverages contain phosphoric acid, whereas other carbonated soft drinks (with some exceptions) do not.
Vitamin D is probably the most important supplement you can take, and one of the best brain food. It acts on more than over 1,000 different genes and is a substrate for testosterone, progesterone, estradiol, and other  hormones.[1] It also influences inflammation and brain calcium absorption.[2] No surprise that optimal vitamin D levels are linked to stronger cognitive function and slower brain aging.[3][4]
At dose #9, I’ve decided to give up on kratom. It is possible that it is helping me in some way that careful testing (eg. dual n-back over weeks) would reveal, but I don’t have a strong belief that kratom would help me (I seem to benefit more from stimulants, and I’m not clear on how an opiate-bearer like kratom could stimulate me). So I have no reason to do careful testing. Oh well.

Lisa Mosconi has a web and media presence and a book Brain Food: The Surprising Science of Eating for Cognitive Power. She claims, “There is increasing evidence that implementing the lifestyle changes described in this book has the potential to prevent Alzheimer’s from developing and also to help slow down or even halt progression of the disease.” What’s more, “eating for your brain…actually helps you achieve peak performance in every part of your life.”
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).
Vitamin C has long been thought to have the power to increase mental agility, and some research suggests that a deficiency may be a risk factor for age-related brain degeneration including dementia and Alzheimer's.  Furthermore, interesting studies demonstrate that vitamin C may be useful in managing anxiety and stress. One of the best sources of this vital vitamin are blackcurrants. Others include red peppers, citrus fruits such as oranges and broccoli.
The biohacking movement is trying to overcome its “N=1” problem (in which a sample size includes only the person doing the experimenting) by sharing experiences online or via meetups. But a biohacking group, like any community organized around a common interest, can easily become an echo chamber. James Alcock, Ph.D., a professor of social psychology at York University in Canada and the author of the book Belief: What It Means to Believe and Why Our Convictions Are So Compelling, says biohackers may be unwittingly painting one another an unreasonably rosy picture of how well nootropics work—even when they don’t.
I met Alex one evening last summer, at an appealingly scruffy bar in the New England city where he lives. Skinny and bearded, and wearing faded hipster jeans, he looked like the lead singer in an indie band. He was ingratiating and articulate, and smoked cigarettes with an ironic air of defiance. Alex was happy enough to talk about his frequent use of Adderall at Harvard, but he didn't want to see his name in print; he's involved with an internet start-up and worried that potential investors might disapprove of his habit.
Another promising "smart pill" is phosphatidylserine, or PS, a natural substance that helps cell walls stay pliable and is thought to boost the effectiveness of neurotransmitters, which relay brain signals. In a May 1991 study published in Neurology, neuroscientist Thomas Crook found that patients with age-associated memory impairment improved their scores on key performance tests after 12 weeks on PS. Yet more research is needed before doctors can know that the supplement is safe and effective.
While it’s no miracle pill, it can certainly give you the edge when it comes to enhanced mental and cognitive processing, as well as boosting your focus and memory retention. So, if you’re the kind of person who’s looking to optimize your performance and get the best results possible, then using an effective nootropic like the Brain Pill is a smart decision that will quickly pay dividends when it’s used in the appropriate way.
The available literature on cognitive enhancing practices at times appears to lump together nootropics and “smart drugs.” Smart drugs are not officially defined, but references to this group generally include Provigil (modafinil), Adderall and Ritalin. Any confusion about the addiction potential of different brain-enhancing drugs can spread misinformation about the individual drugs. There are many nootropics on the market, so the best practice is to focus on the addiction potential of each nootropic of interest or concern.

I tried taking whole pills at 1 and 3 AM. I felt kind of bushed at 9 AM after all the reading, and the 50 minute nap didn’t help much - I was sleep only around 10 minutes and spent most of it thinking or meditation. Just as well the 3D driver is still broken; I doubt the scores would be reasonable. Began to perk up again past 10 AM, then felt more bushed at 1 PM, and so on throughout the day; kind of gave up and began watching & finishing anime (Amagami and Voices of a Distant Star) for the rest of the day with occasional reading breaks (eg. to start James C. Scotts Seeing Like A State, which is as described so far). As expected from the low quality of the day, the recovery sleep was bigger than before: a full 10 hours rather than 9:40; the next day, I slept a normal 8:50, and the following day ~8:20 (woken up early); 10:20 (slept in); 8:44; 8:18 (▁▇▁▁). It will be interesting to see whether my excess sleep remains in the hour range for ’good modafinil nights and two hours for bad modafinil nights.
QUALITY : They use pure and high quality Ingredients and are the ONLY ones we found that had a comprehensive formula including the top 5 most proven ingredients: DHA Omega 3, Huperzine A, Phosphatidylserine, Bacopin and N-Acetyl L-Tyrosine. Thrive Natural’s Super Brain Renew is fortified with just the right ingredients to help your body fully digest the active ingredients. No other brand came close to their comprehensive formula of 39 proven ingredients. The “essential 5” are the most important elements to help improve your memory, concentration, focus, energy and mental clarity. But, what also makes them stand out above all the rest was that they have several supporting vitamins and nutrients to help optimize brain and memory function. A critical factor for us is that this company does not use fillers, binders or synthetics in their product. We love the fact that their capsules are vegetarian, which is a nice bonus for health conscience consumers.

Adderall is composed of a mixture of amphetamine salts – chemical compounds that have numerous potentially positive effects, including increased concentration, awareness and alertness. Amphetamines work, in part, by causing the release of dopamine, a neurotransmitter associated with pleasurable activities like eating. However, an amphetamine-induced release of dopamine occurs automatically – no pleasurable activity needs to occur – but a come-down feeling will likely be experienced eventually, which is associated with feelings of lethargy and mental dullness. Due to this side effect, Adderall cannot be said to be a nootropic.[12]

“Who doesn’t want to maximize their cognitive ability? Who doesn’t want to maximize their muscle mass?” asks Murali Doraiswamy, who has led several trials of cognitive enhancers at Duke University Health System and has been an adviser to pharmaceutical and supplement manufacturers as well as the Food and Drug Administration. He attributes the demand to an increasingly knowledge-based society that values mental quickness and agility above all else.
Another factor to consider is whether the nootropic is natural or synthetic. Natural nootropics generally have effects which are a bit more subtle, while synthetic nootropics can have more pronounced effects. It’s also important to note that there are natural and synthetic nootropics. Some natural nootropics include Ginkgo biloba and ginseng. One benefit to using natural nootropics is they boost brain function and support brain health. They do this by increasing blood flow and oxygen delivery to the arteries and veins in the brain.
