A study mentioned in Neuropsychopharmacology as of August 2002, showed that Bacopa Monnieri decreases the rate of forgetting newly acquired information, memory consolidations, and verbal learning rate. It also helps in enhancing the nerve impulse transmission, which leads to increased alertness. Also, it is known to relieve the effects of anxiety and depression. All these benefits happen as Bacopa Monnieri dosage helps in activating choline acetyltransferase and inhibiting acetylcholinesterase which enhances the levels of acetylcholine in the brain, a chemical that is also associated in enhancing memory and attention.
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.
The general cost of fish oil made me interested in possible substitutes. Seth Roberts uses exclusively flaxseed oil or flaxseed meal, and this seems to work well for him with subjective effects (eg. noticing his Chinese brands seemed to not work, possibly because they were unrefrigerated and slightly rancid). It’s been studied much less than fish oil, but omega acids are confusing enough in general (is there a right ratio? McCluskey’s roundup gives the impression claims about ratios may have been overstated) that I’m not convinced ALA is a much inferior replacement for fish oil’s mixes of EPA & DHA.
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.
Oxiracetam is one of the 3 most popular -racetams; less popular than piracetam but seems to be more popular than aniracetam. Prices have come down substantially since the early 2000s, and stand at around 1.2g/$ or roughly 50 cents a dose, which was low enough to experiment with; key question, does it stack with piracetam or is it redundant for me? (Oxiracetam can’t compete on price with my piracetam pile stockpile: the latter is now a sunk cost and hence free.)
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.
So how do I pull off this stack? It’s quite simple, really. I order 1-milligram nicotine toothpicks on Amazon that I suck on when I’m downing a cup of coffee (the cinnamon flavor blends quite nicely with a cup o’ joe) and I also keep a dispenser of 1.5-milligram nicotine mints in my office. Warning: nicotine can be addictive. I recommend limiting yourself to no more than 1-2 toothpicks and 1-2 mints per day, and only using on more cognitively demanding days. As a bonus, both caffeine and nicotine are potent ergogenic, physical performance-enhancing aids (albeit in higher amounts, closer to 100+ milligrams for caffeine and 2.5+ milligrams for nicotine).
purpose of this research study titled ‘Nootropics Market – Growth, Future Prospects, and Competitive Analysis, 2016 – 2024’ is to provide investors, developers, company executives and industry participants with in-depth analysis to allow them to take strategic initiatives and decisions related to the prospects in the global nootropics products market.
This product is a miracle! I have purchased it TWICE because it is so helpful with my memory and cognition. I bought this product because I needed to strengthen my memory and focus, and I wanted to be awake when I did it! I had just switched to a job that is second shift (2PM-11PM) and it was very difficult to adjust to those hours AND learn all of the new technical systems required for my new job. But after taking this supplement, I noticed a HUGE difference in a few days! I was awake and alert like it was 11AM everyday. But it wasn’t like the jolt you sometimes get from caffeine, more like an alertness after a good night’s sleep. No jitters, no headaches, no stomach upset. Just energy and the feeling of being AWAKE. I am now telling all of my co-workers about it!

My first impression of ~1g around 12:30PM was that while I do not feel like running around, within an hour I did feel like the brain fog was lighter than before. The effect wasn’t dramatic, so I can’t be very confident. Operationalizing brain fog for an experiment might be hard: it doesn’t necessarily feel like I would do better on dual n-back. I took 2 smaller doses 3 and 6 hours later, to no further effect. Over the following weeks and months, I continued to randomly alternate between potassium & non-potassium days. I noticed no effects other than sleep problems.

[…] 2. Blueberries: Also called “brainberries” by Dr. Steven Platt, MD author of Superfoods Rx: Fourteen Foods Proven to Change Your Life, blueberries have one of the highest antioxidant capacities of all fruits and vegetables and are known to improve memory and cognitive function. They have memory-protecting properties and have even been associated with the prevention of Alzheimer’s disease. Add some blueberries to your breakfast and you may not need to check that to-do list several times throughout the day. Also Read The 7 Best Brain Boosting Supplements […]


Nootropics are classically defined as something that a) improves brain health, and b) does no harm. So, while many treatments being advertised online and on TV can be classified as nootropics, some of them don’t fit the bill because of the dangerous and damaging side effects they also confer upon the unwary consumer. In fact, most of the results you might get from searching ‘best brain pills’ are similarly not that great, let alone the best.
Lost confidence.  If you can’t find your keys, much less get through your workday in a timely fashion without a slew of mistakes, you are going to lose confidence in both your brain and yourself.  When you cannot remember where you put things and it takes an absurd amount of effort just to do a simple task, you might question your very sanity.  As your confidence continues to nose-dive, you just end up making more and more mistakes.  It turns into a vicious cycle.
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.

I took 1.5mg of melatonin, and went to bed at ~1:30AM; I woke up around 6:30, took a modafinil pill/200mg, and felt pretty reasonable. By noon my mind started to feel a bit fuzzy, and lunch didn’t make much of it go away. I’ve been looking at studies, and users seem to degrade after 30 hours; I started on mid-Thursday, so call that 10 hours, then 24 (Friday), 24 (Saturday), and 14 (Sunday), totaling 72hrs with <20hrs sleep; this might be equivalent to 52hrs with no sleep, and Wikipedia writes:
This is absolutely fantastic work - Dr. Mosconi's clear, concise prose readily breaks down the science of how we can protect our beloved brains from the horrors of dementia and keep our minds humming beautifully for years. Her mastery of the various key subjects - neurobiology, nutrition, biochemistry - is incredible and her ability to decode complex scientific findings into digestible, easy-to-use advice for the layperson is second to none. This is easily one of the best popular science books I've ever come across and by far the best read on nutrition I know of.
Attention Deficit and Hyperactivity Disorder (ADHD) is a condition that relates to a collection of behavioural symptoms such as hyperactivity, impulsiveness and inattentiveness. It is most commonly diagnosed in childhood between the ages of 6 and 12 when disruptive behaviour begins to show, however, due to a growing awareness of the condition, it is also becoming common among adults. According to the thinktank Demos, the cost of undiagnosed ADHD in adults in the UK who are unable to work or hold down a full-time job are estimated to cost billions of pounds to the nation. They warn that too many may be going through life struggling, unable to access the support ot diagnosis they need, which means there could be a huge amount of wasted talent.
Clinical psychiatrist Emily Deans has a private practice in Massachusetts and teaches at Harvard Medical School. She told me by phone that, in principle, there's "probably nothing dangerous" about the occasional course of nootropics for a hunting trip, finals week, or some big project. Beyond that, she suggests considering that it's possible to build up a tolerance to many neuroactive products if you use them often enough.
It’s that time of the year again. It’s Blue Monday. We’re halfway into January, trudging through the deepest and darkest of the winter months, as we try to keep our heads high after the Christmas festivities with the motivation of our New Year’s resolutions. Some of you may have never heard of Blue Monday and let’s just say you’re not exactly missing out.
As I am not any of the latter, I didn’t really expect a mental benefit. As it happens, I observed nothing. What surprised me was something I had forgotten about: its physical benefits. My performance in Taekwondo classes suddenly improved - specifically, my endurance increased substantially. Before, classes had left me nearly prostrate at the end, but after, I was weary yet fairly alert and happy. (I have done Taekwondo since I was 7, and I have a pretty good sense of what is and is not normal performance for my body. This was not anything as simple as failing to notice increasing fitness or something.) This was driven home to me one day when in a flurry before class, I prepared my customary tea with piracetam, choline & creatine; by the middle of the class, I was feeling faint & tired, had to take a break, and suddenly, thunderstruck, realized that I had absentmindedly forgot to actually drink it! This made me a believer.

1 PM; overall this was a pretty productive day, but I can’t say it was very productive. I would almost say even odds, but for some reason I feel a little more inclined towards modafinil. Say 55%. That night’s sleep was vile: the Zeo says it took me 40 minutes to fall asleep, I only slept 7:37 total, and I woke up 7 times. I’m comfortable taking this as evidence of modafinil (half-life 10 hours, 1 PM to midnight is only 1 full halving), bumping my prediction to 75%. I check, and sure enough - modafinil.
Including comprehensive lists of what to eat and what to avoid, a detailed quiz that will tell you where you are on the brain health spectrum, and 24 mouth-watering brain-boosting recipes that grow out of Dr. Mosconi’s own childhood in Italy, Brain Food gives us the ultimate plan for a healthy brain. Brain Food will appeal to anyone looking to improve memory, prevent cognitive decline, eliminate brain fog, lift depression, or just sharpen their edge.
The most common front-line of treatment for ADHD is medication and cognitive behavioural therapy (CBT). Prescriptions for ADHD drugs such as Ritalin, have doubled to 922,000 a year in the last decade, and whilst it offers symptom management for many, it has also been found to have significant negative side effects such as weight loss, liver toxicity, and suicidal thoughts, and in the short term may suppress pubertal growth. The aetiology of ADHD is multifactorial, meaning that there are varying influencing factors that drive the symptoms. This is perhaps why this condition has been hard to study and find effective treatment for.

Smart drugs offer significant memory enhancing benefits. Clinical studies of the best memory pills have shown gains to focus and memory. Individuals seek the best quality supplements to perform better for higher grades in college courses or become more efficient, productive, and focused at work for career advancement. It is important to choose a high quality supplement to get the results you want.
Huperzine A: This compound is found in a firmoss plant called Huperzia serrata.  Studies conducted on Huperzine A so far have not used the best methodology, so scientists are still not sure how beneficial this compound is for preventing or treating Alzheimer’s disease.  But one review of studies on Huperzine A concluded that the compound “appears to have beneficial effects on improvement of cognitive function, daily living activity, and global clinical assessment in participants with Alzheimer’s disease.”

Every month, our editor puts her name on that month’s best smart bill, in terms of results and value offered to users.
The powder totals 227g of magnesium citrate, hence there is ~0.945g per magnesium citrate pill. The nutritional information states that it contains 119 servings of 0.315g magnesium elemental = 37.485g elemental, as expected, and so likewise there is 0.156g elemental magnesium per pill. This is the same dosage as the second half of the first magnesium citrate experiment (249 gel capsules there, 240 here), where the overdose effect seemed to also happen; so to avoid the overdosage, I will take one pill every other day to halve the dose to an average of ~0.078g/78mg elemental per day (piggybacking on the morning-caffeine experiment to make compliance easier).
There are a variety of substances to get magnesium from. Considerable enthusiasm for the new compound magnesium l-threonate was stirred by 2 small animal rat studies finding that magnesium l-threonate was able to increase magnesium levels in the brain and improve learning/memory tasks. (There are no published human trials as of October 2015, and evidence of publication bias, which I take as evidence against there being large effects in humans.) Animal studies mean very little, of course (see the appendix), but I thought it’d be interesting to try using l-threonate, so I bought the $30 Life Extension Neuro-Mag Magnesium L-Threonate with Calcium and Vitamin D3 (205g), which according to the LEF product page works out to ~60g of Magtein™ magnesium L-threonate and ~4.31g elemental magnesium inasmuch as LEF claims 2000mg of threonate powder provides 144mg elemental magnesium or a 14:1 ratio. (I don’t need the calcium or vitamin D3, but this was the only magnesium l-threonate on Amazon.) Experiment-wise, I’ll probably look at sleep metrics and Mnemosyne performance; I put off designing a blind self-experiment until after trying some.
By blending proven natural cognitive enhancers and naturally occurring smart brain health supporting amino acids like Cordyceps-Sinensis Extract , Coenzyme Q10 , Chlorella (from Green Algae) and Omega-3 Extract to maximize acetylcholine levels with other essential brain health supporting vitamins and amino acids, our powerful and effective brain health supplement assists in elevating serotonin and GABA levels, crucial components to remaining calm, alert, focused and mentally driven while under pressure or stress.
Surgeries – Here's another unpleasant surprise. You're probably thinking we're referring to a brain surgery, but that's not the only surgery that can influence the blood flow to your brain the bad way. For example, a heart surgery can cause hypoperfusion. How? Fat globules, which are released during these kinds of procedures, can find their way to your brain and disrupt the optimal blood flow.
Fitzgerald 2012 and the general absence of successful experiments suggests not, as does the general historic failure of scores of IQ-related interventions in healthy young adults. Of the 10 studies listed in the original section dealing with iodine in children or adults, only 2 show any benefit; in lieu of a meta-analysis, a rule of thumb would be 20%, but both those studies used a package of dozens of nutrients - and not just iodine - so if the responsible substance were randomly picked, that suggests we ought to give it a chance of 20% \times \frac{1}{\text{dozens}} of being iodine! I may be unduly optimistic if I give this as much as 10%.
She repeats the oft-refuted advice to drink at least 8 glasses of water a day. She claims that drinking water improves cognitive performance. Her citation for that claim is a small study in which participants were instructed to fast overnight and not eat or drink anything after 9 pm, so they were presumably somewhat dehydrated. There is no evidence that people who are not dehydrated benefit from increasing water intake.
There are a variety of substances to get magnesium from. Considerable enthusiasm for the new compound magnesium l-threonate was stirred by 2 small animal rat studies finding that magnesium l-threonate was able to increase magnesium levels in the brain and improve learning/memory tasks.

The fact is, many of these compounds in small amounts and less frequent use can be relatively safe, but as you’re probably not surprised to hear, I’m not 100% convinced of the overall long-term safety or efficacy of most smart drugs used frequently or in moderate to high dosages for the reasons stated above. It is true that some are slightly less risky than others and are increasing in popularity among biohackers and medical professionals. They’re also becoming used with high frequency by students, athletes and e-gamers, three populations for which smart drug “doping control” is becoming more frequently banned and considered to be illegal use of performance-enhancing drugs. Yes, “brain doping” and “brain PED’s” (brain Performance Enhancing Drugs) are now a thing. But I’d consider carefully the use of smart drugs as daily go-to brain enhancing supplements, especially in light of the safer alternative you’re about to discover: the entire category of natural and synthetic nootropic compounds.
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.

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.
During pregnancy and after pregnancy there is often a concern for the potential depletion of the maternal nutrient reservoir due to the needs of the growing foetus. A nutrient that is particularly important for mental wellbeing and is also essential for the growth of the foetus’s brain, is DHA. This is an omega 3 fatty acid that is found in oily fish and is the primary structural component of brain tissue, as well as playing a crucial role in the maintenance of brain cells and neurotransmitter metabolism (our body can also convert plant sources of omegas 3’s into DHA, such as those found in flaxseeds or chia seeds into DHA, but the conversion can often very poor). Deficiency in this nutrient during pregnancy is common, namely because of lack of seafood intake (the most bioavailable source of DHA) due to poor eating habits and concerns of mercury levels in fish during pregnancy, as well as higher requirements during foetal growth, which can lead to depletion. Due to the role that DHA plays in neurotransmitter metabolism, deficiency in this nutrient has been correlated to symptoms of depression during pregnancy (7). In order, to support your intake of omega 3, aim to have 3 portions of oily fish a week from sources that are low in mercury. These are mainly small fish that have a short life-span such as sardines, mackerel and herring. If you are vegetarian or vegan, although omega 3 is less readily available, it is still possible to get this nutrient from your diet through flax seeds, chia seeds, walnuts and seaweed. If you feel you may not be getting enough through your diet, you may want to consider using a good quality fish oil supplement (or algae based supplement if vegan) as an option. With fish oils, aim to choose a supplement that has been filtered for heavy metals and other pollutants to make sure you're getting the full benefits of the omega 3 oils.

Zack explained that he didn't really like the term enhancement: "We're not talking about superhuman intelligence. No one's saying we're coming out with a pill that's going to make you smarter than Einstein! What we're really talking about is enabling people." He sketched a bell curve on the back of a napkin. "Almost every drug in development is something that will take someone who's working at, like, 40% or 50%, and take them up to 80," he said.

Siberian Ginseng: Also known as Eleutherococcus senticosus, this herb is native to Russia, China, Japan and other areas of east Asia.  There is not a lot of western research backing Siberian Ginseng as a nootropic yet, but the supplement has been used in traditional medicine in the Far East for quite some time.  Plenty of anecdotal evidence backs it up as an excellent memory and attention enhancer.
Essential fatty acids (EFAs) cannot be made by the body which means they must be obtained through diet. The most effective omega-3 fats occur naturally in oily fish in the form of EPA and DHA. Good plant sources include linseed (flaxseed), soya beans, pumpkin seeds, walnuts and their oils. These fats are important for healthy brain function, the heart, joints and our general wellbeing. What makes oily fish so good is that they contain the active form of these fats, EPA and DHA, in a ready-made form, which enables the body to use it easily. The main sources of oily fish include salmon, trout, mackerel, herring, sardines, pilchards and kippers. Low DHA levels have been linked to an increased risk of dementia, Alzheimer's disease and memory loss whilst having sufficient levels of both EPA and DHA is thought to help us manage stress and helps make the good mood brain chemical, serotonin. If you're vegetarian or vegan, you may wish to add seeds like linseed and chia to your diet, or consider a plant-based omega-3 supplement. If you are considering taking a supplement speak to your GP first.

If there is one quality a person needs to achieve great things in life, it’s intelligence. Success comes easier to those who are smart- just ask the many college students who take study drugs they don’t really need to absorb more, work faster, longer and better, and get the good grades they would literally kill for- even if it means they are slowly killing themselves.
As a student Seltzer used both Adderall and piracetam. Now, after a hiatus of several years, he has recently resumed taking neuroenhancers. In addition to piracetam, he took a stack of supplements that he thought helped his brain to function: fish oils, five antioxidants, a product called ChocoMind and a number of others, all available at the health-food store. He was thinking about adding modafinil, but hadn't yet. For breakfast every morning he concocted a slurry of oatmeal, berries, soy milk, pomegranate juice, flaxseed, almond meal, raw eggs and protein powder. The goal behind the recipe was efficiency: to rely on "one goop you could eat or drink that would have everything you need nutritionally for your brain and body. I wanted to be able to keep it down - that was it." (He told me this in the kitchen of his apartment; he lives with a roommate, who walked in while we were talking, listened perplexedly for a moment, then put a frozen pizza in the oven.)
The fish oil can be considered a free sunk cost: I would take it in the absence of an experiment. The empty pill capsules could be used for something else, so we’ll put the 500 at $5. Filling 500 capsules with fish and olive oil will be messy and take an hour. Taking them regularly can be added to my habitual morning routine for vitamin D and the lithium experiment, so that is close to free but we’ll call it an hour over the 250 days. Recording mood/productivity is also free a sunk cost as it’s necessary for the other experiments; but recording dual n-back scores is more expensive: each round is ~2 minutes and one wants >=5, so each block will cost >10 minutes, so 18 tests will be >180 minutes or >3 hours. So >5 hours. Total: 5 + (>5 \times 7.25) = >41.
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.
Absorption of nicotine across biological membranes depends on pH. Nicotine is a weak base with a pKa of 8.0 (Fowler, 1954). In its ionized state, such as in acidic environments, nicotine does not rapidly cross membranes…About 80 to 90% of inhaled nicotine is absorbed during smoking as assessed using C14-nicotine (Armitage et al., 1975). The efficacy of absorption of nicotine from environmental smoke in nonsmoking women has been measured to be 60 to 80% (Iwase et al., 1991)…The various formulations of nicotine replacement therapy (NRT), such as nicotine gum, transdermal patch, nasal spray, inhaler, sublingual tablets, and lozenges, are buffered to alkaline pH to facilitate the absorption of nicotine through cell membranes. Absorption of nicotine from all NRTs is slower and the increase in nicotine blood levels more gradual than from smoking (Table 1). This slow increase in blood and especially brain levels results in low abuse liability of NRTs (Henningfield and Keenan, 1993; West et al., 2000). Only nasal spray provides a rapid delivery of nicotine that is closer to the rate of nicotine delivery achieved with smoking (Sutherland et al., 1992; Gourlay and Benowitz, 1997; Guthrie et al., 1999). The absolute dose of nicotine absorbed systemically from nicotine gum is much less than the nicotine content of the gum, in part, because considerable nicotine is swallowed with subsequent first-pass metabolism (Benowitz et al., 1987). Some nicotine is also retained in chewed gum. A portion of the nicotine dose is swallowed and subjected to first-pass metabolism when using other NRTs, inhaler, sublingual tablets, nasal spray, and lozenges (Johansson et al., 1991; Bergstrom et al., 1995; Lunell et al., 1996; Molander and Lunell, 2001; Choi et al., 2003). Bioavailability for these products with absorption mainly through the mucosa of the oral cavity and a considerable swallowed portion is about 50 to 80% (Table 1)…Nicotine is poorly absorbed from the stomach because it is protonated (ionized) in the acidic gastric fluid, but is well absorbed in the small intestine, which has a more alkaline pH and a large surface area. Following the administration of nicotine capsules or nicotine in solution, peak concentrations are reached in about 1 h (Benowitz et al., 1991; Zins et al., 1997; Dempsey et al., 2004). The oral bioavailability of nicotine is about 20 to 45% (Benowitz et al., 1991; Compton et al., 1997; Zins et al., 1997). Oral bioavailability is incomplete because of the hepatic first-pass metabolism. Also the bioavailability after colonic (enema) administration of nicotine (examined as a potential therapy for ulcerative colitis) is low, around 15 to 25%, presumably due to hepatic first-pass metabolism (Zins et al., 1997). Cotinine is much more polar than nicotine, is metabolized more slowly, and undergoes little, if any, first-pass metabolism after oral dosing (Benowitz et al., 1983b; De Schepper et al., 1987; Zevin et al., 1997).
I asked Marcus which nootropic he would want if he were stranded on a desert island. "I guess it would depend on the challenges I was facing on the island. If staying healthy was the biggest challenge, then I'd choose AC-11," he said. "If I needed to stay motivated to rebuild the village, I would choose Mucuna [pruriens]. If I was hunting, I'd choose Huperzia serrata, for mental acuity and speed."
It goes without saying that ensuring your brain performs at its top capacity levels is every person’s priority. However, the trouble is this is something easier said than done. We live in the extremely competitive and demanding modern world. That’s a fact. We aren’t getting any younger. That’s also a fact. The inevitable aging process takes a toll on our mental capacity and brain itself, as well. So, what can you do about it? Natural supplements can boost your brain power in an efficient and harmless way. This is how one of these supplements named Brain Pill caught our attention.
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.

A fancier method of imputation would be multiple imputation using, for example, the R library mice (Multivariate Imputation by Chained Equations) (guide), which will try to impute all missing values in a way which mimicks the internal structure of the data and provide several possible datasets to give us an idea of what the underlying data might have looked like, so we can see how our estimates improve with no missingness & how much of the estimate is now due to the imputation:
Dallas Michael Cyr, a 41-year-old life coach and business mentor in San Diego, California, also says he experienced a mental improvement when he regularly took another product called Qualia Mind, which its makers say enhances focus, energy, mental clarity, memory and even creativity and mood. "One of the biggest things I noticed was it was much more difficult to be distracted," says Cyr, who took the supplements for about six months but felt their effects last longer. While he's naturally great at starting projects and tasks, the product allowed him to be a "great finisher" too, he says.
