"Instead of messing it up, we should be appreciating something that nature has taken years to optimize," Dr. Lisa mentions. But, we aren't messing it up voluntarily or, at the very least, on any conscious or malicious level. She attributes our disregard for neuro-nutrition to a series of factors, which include the portion size of meals, how parents don't have the time to cook or teach children how to eat healthily, the big influence of cafeteria food, and our "always on the go" culture. According to her, this leads us to unconsciously choose meals which are poor quality and high in sugars, a deathly combination for our brains.
Take the synthetic nootropic piracetam, for example. Since piracetam has been shown to improve cell membrane function and cause a host of neuroprotective effects, when combined with other cell membrane stabilizing supplements such as choline and DHA, the brain cells on piracetam can better signal and relay messages to each other for a longer period of time, which improves cognition and brain activity and decreases risk of a crash. So one example of an intelligent “stack” is piracetam taken with choline and DHA.
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.)
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.
Similarly, Mehta et al 2000 noted that the positive effects of methylphenidate (40 mg) on spatial working memory performance were greatest in those volunteers with lower baseline working memory capacity. In a study of the effects of ginkgo biloba in healthy young adults, Stough et al 2001 found improved performance in the Trail-Making Test A only in the half with the lower verbal IQ.

Began double-blind trial. Today I took one pill blindly at 1:53 PM. at the end of the day when I have written down my impressions and guess whether it was one of the Adderall pills, then I can look in the baggy and count and see whether it was. there are many other procedures one can take to blind oneself (have an accomplice mix up a sequence of pills and record what the sequence was; don’t count & see but blindly take a photograph of the pill each day, etc.) Around 3, I begin to wonder whether it was Adderall because I am arguing more than usual on IRC and my heart rate seems a bit high just sitting down. 6 PM: I’ve started to think it was a placebo. My heart rate is back to normal, I am having difficulty concentrating on long text, and my appetite has shown up for dinner (although I didn’t have lunch, I don’t think I had lunch yesterday and yesterday the hunger didn’t show up until past 7). Productivity wise, it has been a normal day. All in all, I’m not too sure, but I think I’d guess it was Adderall with 40% confidence (another way of saying placebo with 60% confidence). When I go to examine the baggie at 8:20 PM, I find out… it was an Adderall pill after all. Oh dear. One little strike against Adderall that I guessed wrong. It may be that the problem is that I am intrinsically a little worse today (normal variation? come down from Adderall?).
This supplement is dangerous and should not be sold. I have taken brain supplements for a while and each of them are very similar, EXCEPT for Addium. On the day I took Addium many blood vessels in my hands burst, and two on my face burst. With their "proprietary blend" not being detailed as to the amount of each ingredient (only listed in the aggregate of 500mg Proprietary Blend) you have no way of determining which ingredient may or may not be too much. I can only recommend to stay away from this supplement.
l-theanine (Examine.com) is occasionally mentioned on Reddit or Imminst or LessWrong33 but is rarely a top-level post or article; this is probably because theanine was discovered a very long time ago (>61 years ago), and it’s a pretty straightforward substance. It’s a weak relaxant/anxiolytic (Google Scholar) which is possibly responsible for a few of the health benefits of tea, and which works synergistically with caffeine (and is probably why caffeine delivered through coffee feels different from the same amount consumed in tea - in one study, separate caffeine and theanine were a mixed bag, but the combination beat placebo on all measurements). The half-life in humans seems to be pretty short, with van der Pijl 2010 putting it ~60 minutes. This suggests to me that regular tea consumption over a day is best, or at least that one should lower caffeine use - combining caffeine and theanine into a single-dose pill has the problem of caffeine’s half-life being much longer so the caffeine will be acting after the theanine has been largely eliminated. The problem with getting it via tea is that teas can vary widely in their theanine levels and the variations don’t seem to be consistent either, nor is it clear how to estimate them. (If you take a large dose in theanine like 400mg in water, you can taste the sweetness, but it’s subtle enough I doubt anyone can actually distinguish the theanine levels of tea; incidentally, r-theanine - the useless racemic other version - anecdotally tastes weaker and less sweet than l-theanine.)
Brain Pill is an original, safe and effective nootropic agent. Unlike the many agents available in the market that do not guarantee their effectiveness, Brain Pill bases its working abilities in clinical research and trials done to the product. You should, therefore, prioritize purchasing this product if you fall in the fold. Ken Jennings, a 74-game Jeopardy champion recommends this product for enhanced* brain functioning.
We felt that True Focus offered a good product but the price was slightly high compared to others. Their website doesn’t show a clear money-back guarantee though, which definitely reduced their rating. We found that their customer reviews were mixed and saw that some consumers did not mind paying a little more for a product that is more consumer friendly.
Zack and Casey Lynch are a young couple who, in 2005, launched NeuroInsights, a company that advises investors on developments in brain-science technology. (Since then, they've also founded a lobbying group, the Neurotechnology Industry Organization.) Casey and Zack met as undergraduates at UCLA; she went on to get a master's in neuroscience and he became an executive at a software company. Last summer I had coffee with them in San Francisco and they both spoke with casual certainty about the coming market for neuroenhancers. Zack, whose book, The Neuro Revolution, was published in July, said: "We live in an information society. What's the next form of human society? The neuro-society." In coming years, he said, scientists will understand the brain better, and we'll have improved neuroenhancers that some people will use therapeutically, others because they are "on the borderline of needing them therapeutically" and others purely "for competitive advantage".
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.
The BoredAt websites - which allow college students to chat idly while they're ostensibly studying - are filled with messages about Adderall. Posts like these, from the BoredAtPenn site, are typical: "I have some Adderall - I'm sitting by room 101.10 in a grey shirt and headphones"; "I have Adderall for sale 20mg for $15"; "I took Adderall at 8pm, it's 6:30am and I've barely blinked." On the Columbia site one poster complains that her friends take Adderall "like candy", adding: "I don't want to be at a disadvantage to everyone else. Is it really that dangerous? My grades weren't that great this year and I could do with a bump." A Columbia student responds: "It's probably not a good idea if you're not prescribed", but offers practical advice anyway: "Keep the dose normal and don't grind them up or snort them." Occasional dissenters ("I think there should be random drug testing at every exam") are drowned out by testimonials like this one, from the BoredAtHarvard site: "I don't want to be a pusher or start people on something bad, but Adderall is amazing."
As discussed in my iodine essay (FDA adverse events), iodine is a powerful health intervention as it eliminates cretinism and improves average IQ by a shocking magnitude. If this effect were possible for non-fetuses in general, it would be the best nootropic ever discovered, and so I looked at it very closely. Unfortunately, after going through ~20 experiments looking for ones which intervened with iodine post-birth and took measures of cognitive function, my meta-analysis concludes that: the effect is small and driven mostly by one outlier study. Once you are born, it’s too late. But the results could be wrong, and iodine might be cheap enough to take anyway, or take for non-IQ reasons. (This possibility was further weakened for me by an August 2013 blood test of TSH which put me at 3.71 uIU/ml, comfortably within the reference range of 0.27-4.20.)
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.
Related to the famous -racetams but reportedly better (and much less bulky), Noopept is one of the many obscure Russian nootropics. (Further reading: Google Scholar, Examine.com, Reddit, Longecity, Bluelight.ru.) Its advantages seem to be that it’s far more compact than piracetam and doesn’t taste awful so it’s easier to store and consume; doesn’t have the cloud hanging over it that piracetam does due to the FDA letters, so it’s easy to purchase through normal channels; is cheap on a per-dose basis; and it has fans claiming it is better than piracetam.
I was contacted by the Longecity user lostfalco, and read through some of his writings on the topic. I had never heard of LLLT before, but the mitochondria mechanism didn’t sound impossible (although I wondered whether it made sense at a quantity level14151617), and there was at least some research backing it; more importantly, lostfalco had discovered that devices for LLLT could be obtained as cheap as $15. (Clearly no one will be getting rich off LLLT or affiliate revenue any time soon.) Nor could I think of any way the LLLT could be easily harmful: there were no drugs involved, physical contact was unnecessary, power output was too low to directly damage through heating, and if it had no LLLT-style effect but some sort of circadian effect through hitting photoreceptors, using it in the morning wouldn’t seem to interfere with sleep.
Spaced repetition at midnight: 3.68. (Graphing preceding and following days: ▅▄▆▆▁▅▆▃▆▄█ ▄ ▂▄▄▅) DNB starting 12:55 AM: 30/34/41. Transcribed Sawaragi 2005, then took a walk. DNB starting 6:45 AM: 45/44/33. Decided to take a nap and then take half the armodafinil on awakening, before breakfast. I wound up oversleeping until noon (4:28); since it was so late, I took only half the armodafinil sublingually. I spent the afternoon learning how to do value of information calculations, and then carefully working through 8 or 9 examples for my various pages, which I published on Lesswrong. That was a useful little project. DNB starting 12:09 AM: 30/38/48. (To graph the preceding day and this night: ▇▂█▆▅▃▃▇▇▇▁▂▄ ▅▅▁▁▃▆) Nights: 9:13; 7:24; 9:13; 8:20; 8:31.
Sure, you could certainly swallow too much St. John’s Wort and create the same type of serotonin or neurotransmitter issues you could create with a synthetic smart drug, but it’s far more difficult to harm yourself with a nootropic compared to a synthetic smart drug. Although synthetic, laboratory-designed nootropics do indeed exist, even those are not as harsh on the biology as a smart drug and have a mechanism of action that is a bit more natural. Let’s begin with the more natural nootropics.
Nootropics (/noʊ.əˈtrɒpɪks/ noh-ə-TROP-iks) (colloquial: smart drugs and cognitive enhancers) are drugs, supplements, and other substances that may improve cognitive function, particularly executive functions, memory, creativity, or motivation, in healthy individuals. While many substances are purported to improve cognition, research is at a preliminary stage as of 2018, and the effects of the majority of these agents are not fully determined.
