According to McCabe's research team, white male undergraduates at highly competitive schools are the most frequent student users of neuroenhancers. Users are also more likely to belong to a fraternity or a sorority, and to have a grade point average (GPA) of 3.0 - ie satisfactory - or lower. They are 10 times as likely to report that they have smoked marijuana in the past year and 20 times as likely to say that they have used cocaine. In other words, they are decent students at schools where to be a great student you have to give up a lot more partying than they're willing to give up.
Fish oil (Examine.com, buyer’s guide) provides benefits relating to general mood (eg. inflammation & anxiety; see later on anxiety) and anti-schizophrenia; it is one of the better supplements one can take. (The known risks are a higher rate of prostate cancer and internal bleeding, but are outweighed by the cardiac benefits - assuming those benefits exist, anyway, which may not be true.) The benefits of omega acids are well-researched.

Blueberries. "Brainberries" is what Steven Pratt, MD, author of Superfoods Rx: Fourteen Foods Proven to Change Your Life, calls these tasty fruits. Pratt, who is also on staff at Scripps Memorial Hospital in La Jolla, Calif., says that in animal studies researchers have found that blueberries help protect the brain from oxidative stress and may reduce the effects of age-related conditions such as Alzheimer's disease or dementia. Studies have also shown that diets rich in blueberries significantly improved both the learning capacity and motor skills of aging rats, making them mentally equivalent to much younger rats. Ann Kulze, MD, author of Dr. Ann's 10-Step Diet: A Simple Plan for Permanent Weight Loss & Lifelong Vitality, recommends adding at least 1 cup of blueberries a day in any form -- fresh, frozen, or freeze-dried.

And without those precious nutrients, your brain will start to wither. In a recent Bulletproof Radio podcast episode [iTunes], I talked with neuroscientist Dale Bredesen about why neurodegeneration happens. One of the three most common causes of brain aging is a lack of specific brain nutrients (check out the episode to hear about the other two main causes of brain aging, and what you can do about them).
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.
(In particular, I don’t think it’s because there’s a sudden new surge of drugs. FDA drug approval has been decreasing over the past few decades, so this is unlikely a priori. More specifically, many of the major or hot drugs go back a long time. Bacopa goes back millennia, melatonin I don’t even know, piracetam was the ’60s, modafinil was ’70s or ’80s, ALCAR was ’80s AFAIK, Noopept & coluracetam were ’90s, and so on.)
To understand further about how food intolerances can impact our mental health, it is important to explain the relationship between our gut microbiome, the immune system and our brain in a little more detail. The walls of our digestive tract provide a barrier between what we eat and the rest of our body and an unhealthy gut microbiome can lead to increased levels of inflammation, leaving the walls vulnerable to structural damage (4). Our intestinal wall is composed of cell junctions that prevent bacteria and large food molecules from entering the bloodstream, however, if these become damaged, proteins from foods that should not be circulating in our bloodstream can enter and an immune response is mounted as a reaction. This response is mediated by IgG, an antibody, that helps to protect against bacterial and viral infections as well as food antigens and is the most abundant immune cell in the body. Whilst food antigens are usually quickly cleared by an intelligent system called the reticuloendothelial system, with structural damage and a poor gut microbiome, this immune response can keep reoccurring. It is suggested that a chronic immune response such as this can have a negative impact on the brain, damaging its own structural barrier, called the Blood Brain Barrier (5).
Reason: Acetyl-L-carnitine can protect the brain from neurotoxicity. It can also ward off oxygen deprivation. Acetyl-L-carnitine can even preserve cells energy-producing mitochondria. Plus, it can rejuvenate mental and physical function. Dosages for studies have been in the 1,500 – 4,000 mg range. These are divided into two or three doses. However, we recommend no more than 1,000 mg of acetyl-L-carnitine a day without medical supervision.

Somewhat ironically given the stereotypes, while I was in college I dabbled very little in nootropics, sticking to melatonin and tea. Since then I have come to find nootropics useful, and intellectually interesting: they shed light on issues in philosophy of biology & evolution, argue against naive psychological dualism and for materialism, offer cases in point on the history of technology & civilization or recent psychology theories about addiction & willpower, challenge our understanding of the validity of statistics and psychology - where they don’t offer nifty little problems in statistics and economics themselves, and are excellent fodder for the young Quantified Self movement4; modafinil itself demonstrates the little-known fact that sleep has no accepted evolutionary explanation. (The hard drugs also have more ramifications than one might expect: how can one understand the history of Southeast Asia and the Vietnamese War without reference to heroin, or more contemporaneously, how can one understand the lasting appeal of the Taliban in Afghanistan and the unpopularity & corruption of the central government without reference to the Taliban’s frequent anti-drug campaigns or the drug-funded warlords of the Northern Alliance?)


When Giurgea coined the word nootropic (combining the Greek words for mind and bending) in the 1970s, he was focused on a drug he had synthesized called piracetam. Although it is approved in many countries, it isn’t categorized as a prescription drug in the United States. That means it can be purchased online, along with a number of newer formulations in the same drug family (including aniracetam, phenylpiracetam, and oxiracetam). Some studies have shown beneficial effects, including one in the 1990s that indicated possible improvement in the hippocampal membranes in Alzheimer’s patients. But long-term studies haven’t yet borne out the hype.
The metal magnesium (Examine.com), like potassium (which didn’t help me), plays many biological roles and has an RDA for me of 400mg which is higher than I likely get (most people apparently get less, with 68% of American adults
The task of building a better mousetrap just got a lot harder. Scientists at Princeton University recently created a strain of smarter mice by inserting a gene that boosts the activity of brain cells. The mice can learn to navigate mazes and find or recognize objects faster than run-of-the-mill rodents. The news, announced in the Sept. 2, 1999 issue of the journal Nature, raises the possibility that genetic engineers may someday be able to help humans learn and remember faster, too.
Brain focus pills largely contain chemical components like L-theanine which is naturally found in green and black tea. It’s associated with enhancing alertness, cognition, relaxation, arousal, and reducing anxiety to a large extent.  Theanine is an amino and glutamic acid that has been proven to be a safe psychoactive substance. There are studies that suggest that this compound influences, the expression in the genes present in the brain which is responsible for aggression, fear and memory. This, in turn, helps in balancing the behavioural responses to stress and also helps in improving specific conditions, like Post Traumatic Stress Disorder (PTSD).
This doesn’t fit the U-curve so well: while 60mg is substantially negative as one would extrapolate from 30mg being ~0, 48mg is actually better than 15mg. But we bought the estimates of 48mg/60mg at a steep price - we ignore the influence of magnesium which we know influences the data a great deal. And the higher doses were added towards the end, so may be influenced by the magnesium starting/stopping. Another fix for the missingness is to impute the missing data. In this case, we might argue that the placebo days of the magnesium experiment were identical to taking no magnesium at all and so we can classify each NA as a placebo day, and rerun the desired analysis:
at first impression it took a while to kick in... then a burst of creativity... after 15 days of taking it, I noticed a plateau affect... I kept taking it... took the two daily in one dose and I noticed I was very awake but lacked the initiative to do anything, I noticed an increase in libido which kind of sucked because I'm single but that boost of creativity that was experienced the firs couple of days was not there... I don't know if it has to do with the fact that I skipped a couple of days. I still have maybe like 10 doses left... I purchased a bottle of Accellerin and I noticed that it's the same bottle with the same lettering... is this a newer version of Addium? Anyway, I'm going to keep on taking the product to finish the bottle and I'll give a second review within the next 15 days.
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.
Our top recommendation for cognitive energy enhancement is Brainol. This product is formulated from all natural ingredients. Brainol is a product that works internally. This herbal blend contains 19 key ingredients such as Huperzine A, L-Tyrosine, L-Theanine, St. John’s Wort, Phosphatidylserine, Bacopa Monnieri and Guarana, to name but a few. There are no unwanted side effects from these all natural ingredients.
Evidence in support of the neuroprotective effects of flavonoids has increased significantly in recent years, although to date much of this evidence has emerged from animal rather than human studies. Nonetheless, with a view to making recommendations for future good practice, we review 15 existing human dietary intervention studies that have examined the effects of particular types of flavonoid on cognitive performance. The studies employed a total of 55 different cognitive tests covering a broad range of cognitive domains. Most studies incorporated at least one measure of executive function/working memory, with nine reporting significant improvements in performance as a function of flavonoid supplementation compared to a control group. However, some domains were overlooked completely (e.g. implicit memory, prospective memory), and for the most part there was little consistency in terms of the particular cognitive tests used making across study comparisons difficult. Furthermore, there was some confusion concerning what aspects of cognitive function particular tests were actually measuring. Overall, while initial results are encouraging, future studies need to pay careful attention when selecting cognitive measures, especially in terms of ensuring that tasks are actually sensitive enough to detect treatment effects.
Compared with those reporting no use, subjects drinking >4 cups/day of decaffeinated coffee were at increased risk of RA [rheumatoid arthritis] (RR 2.58, 95% CI 1.63-4.06). In contrast, women consuming >3 cups/day of tea displayed a decreased risk of RA (RR 0.39, 95% CI 0.16-0.97) compared with women who never drank tea. Caffeinated coffee and daily caffeine intake were not associated with the development of RA.
The important factors seem to be: #1/MR6 (Creativity.self.rating, Time.Bitcoin, Time.Backups, Time.Blackmarkets, Gwern.net.linecount.log), #2/MR1 (Time.PDF, Time.Stats), #7/MR7 (Time.Writing, Time.Sysadmin, Time.Programming, Gwern.net.patches.log), and #8/MR8 (Time.States, Time.SRS, Time.Sysadmin, Time.Backups, Time.Blackmarkets). The rest seem to be time-wasting or reflect dual n-back/DNB usage (which is not relevant in the LLLT time period).
Working memory has been likened to a mental scratch pad: you use it to keep relevant data in mind while you're completing a task. (Imagine a cross-examination, in which a lawyer has to keep track of the answers a witness has given and formulate new questions based on them.) In one common test subjects are shown a series of items - usually letters or numbers - and then presented with challenges: was this number or letter in the series? Was this one? In the working-memory tests, subjects performed better on neuroenhancers, though several of the studies suggested that the effect depended on how good a subject's working memory was to begin with: the better it was, the less benefit the drugs provided.
Because modafinil works in a manner similar to methylphenidate, it also bears similar risks. The improper dosage or abuse of modafinil may lead to the disrupted development of executive controls like decision-making and working memory. Modafinil’s effects may also depend upon the IQ of the taker. Two university studies determined that in a test of sustained attention, modafinil only improved cognition in the group with “lower” IQs. Although safer than other stimulants due to its milder effect on neurotransmitter levels, there are still risks associated with any kind of drug that affects dopaminergic neurotransmission, mostly because this can lead to addiction and, similar to a pornography user who needs increasingly fringe porn to achieve the same effect, can produce a resistance or lowered sensitivity to dopamine.

Our current natural brain health formula contains Cordyceps-Sinensis Extract as well as the complete balance of brain health supporting nutrients that work perfectly together to help your body elevate essential acetylcholine levels while increasing the neurological components (neurotransmitters) needed to help you stay alert, focused, mentally driven and calm.


"Herbs will have several different compounds in them, as opposed to, let's say, a drug like amphetamine, which is basically one compound, one molecule," Sahelian says. "Herbs will have a set of several or several dozen compounds in them. It's difficult to pinpoint which one of them is the most active or whether it's the combination of many of them that are producing the result."
There is no official data on their usage, but nootropics as well as other smart drugs appear popular in the Silicon Valley. “I would say that most tech companies will have at least one person on something,” says Noehr. It is a hotbed of interest because it is a mentally competitive environment, says Jesse Lawler, a LA based software developer and nootropics enthusiast who produces the podcast Smart Drug Smarts. “They really see this as translating into dollars.” But Silicon Valley types also do care about safely enhancing their most prized asset – their brains – which can give nootropics an added appeal, he says.
So, I have started a randomized experiment; should take 2 months, given the size of the correlation. If that turns out to be successful too, I’ll have to look into methods of blinding - for example, some sort of electronic doohickey which turns on randomly half the time and which records whether it’s on somewhere one can’t see. (Then for the experiment, one hooks up the LED, turns the doohickey on, and applies directly to forehead, checking the next morning to see whether it was really on or off).

Choosing to take smart drugs is not an effective or long term solution. Smart drugs may help you study faster or keep you awake longer, but they are not your best option. Most of the ADHD medications are based on an amphetamine structure and they are not healthy for your heart or your liver. Also, by taking smart drugs, you are putting yourself at considerable risk for addiction to these substances.


How exactly – and if – nootropics work varies widely. Some may work, for example, by strengthening certain brain pathways for neurotransmitters like dopamine, which is involved in motivation, Barbour says. Others aim to boost blood flow – and therefore funnel nutrients – to the brain to support cell growth and regeneration. Others protect brain cells and connections from inflammation, which is believed to be a factor in conditions like Alzheimer's, Barbour explains. Still others boost metabolism or pack in vitamins that may help protect the brain and the rest of the nervous system, explains Dr. Anna Hohler, an associate professor of neurology at Boston University School of Medicine and a fellow of the American Academy of Neurology.
Takao Hensch, a Harvard professor of cellular biology and part of a Boston Children’s Hospital team, found that the drug encouraged the brain to learn new skills as quickly as the sponge-like brain of an infant in her patient Shannon, an otherwise normal 14-year-old girl who suffers from extremely poor eyesight brought on by amblyopia, commonly known as lazy eye. In a matter of months, the drug helped Shannon’s brain relearn how to use her eye which resulted in markedly improved vision.
That first night, I had severe trouble sleeping, falling asleep in 30 minutes rather than my usual 19.6±11.9, waking up 12 times (5.9±3.4), and spending ~90 minutes awake (18.1±16.2), and naturally I felt unrested the next day; I initially assumed it was because I had left a fan on (moving air keeps me awake) but the new potassium is also a possible culprit. When I asked, Kevin said:

Green tea is widely drunk in many cultures, especially in Asia, and is known to have potent health benefits. These benefits are attributed to its polyphenol content (particularly the flavanols and flavonols). In cell cultures and animal studies, the polyphenols have been proven to prevent neurotoxin-induced cell injury. Green tea also has anti-inflammatory properties and, according to a study performed on aged mice, may delay memory regression. It’s safe to drink several cups of green tea per day, though it may be more efficacious to take a green tea extract supplement to reach a daily dose of 400 to 500 mg of EGCG, one of the main active components of green tea.
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.
That left me with 329 days of data. The results are that (correcting for the magnesium citrate self-experiment I was running during the time period which did not turn out too great) days on which I happened to use my LED device for LLLT were much better than regular days. Below is a graph showing the entire MP dataseries with LOESS-smoothed lines showing LLLT vs non-LLLT days:
Dr Hart explained how communication between the gut and the brain is controlled via our immune system, our endocrine system (hormones) and our central nervous system, which are all under the influence of the bacteria in our gut. The types and amount of these bacteria, known as our gut microbiome, can be directly impacted by factors such as diet, stress, pollution and medications (2) and the composition of the microbiome is also understood to affect one’s susceptibility to food sensitivities and intolerances (3).  
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." 

When comparing supplements, consider products with a score above 90% to get the greatest benefit from smart pills to improve memory. Additionally, we consider the reviews that users send to us when scoring supplements, so you can determine how well products work for others and use this information to make an informed decision. Every month, our editor puts her name on that month’s best smart bill, in terms of results and value offered to users.

…The first time I took supplemental potassium (50% US RDA in a lot of water), it was like a brain fog lifted that I never knew I had, and I felt profoundly energized in a way that made me feel exercise was reasonable and prudent, which resulted in me and the roommate that had just supplemented potassium going for an hour long walk at 2AM. Experiences since then have not been quite so profound (which probably was so stark for me as I was likely fixing an acute deficiency), but I can still count on a moderately large amount of potassium to give me a solid, nearly side effect free performance boost for a few hours…I had been doing Bikram yoga on and off, and I think I wasn’t keeping up the practice because I wasn’t able to properly rehydrate myself.


With so many different ones to choose from, choosing the best nootropics for you can be overwhelming at times. As usual, a decision this important will require research. Study up on the top nootropics which catch your eye the most. The nootropics you take will depend on what you want the enhancement for. The ingredients within each nootropic determine its specific function. For example, some nootropics contain ginkgo biloba, which can help memory, thinking speed, and increase attention span. Check the nootropic ingredients as you determine what end results you want to see.
