Brain Awake is produced by Irwin Naturals. The ingredients are natural and include some key ingredients. However, it also contained several other inactive ingredients that raised some concerns - namely, beeswax and silicone dioxide. We were not sure why these ingredients are included, and could not find any real explanation as to why they are contained within this product. That said, when we tested the ingredients in this product, they were as reported on the bottle.


Upon examining the photographs, I noticed no difference in eye color, but it seems that my move had changed the ambient lighting in the morning and so there was a clear difference between the two sets of photographs! The before photographs had brighter lighting than the after photographs. Regardless, I decided to run a small survey on QuickSurveys/Toluna to confirm my diagnosis of no-change; the survey was 11 forced-choice pairs of photographs (before-after), with the instructions as follows:
Barbara Sahakian, a neuroscientist at Cambridge University, doesn’t dismiss the possibility of nootropics to enhance cognitive function in healthy people. She would like to see society think about what might be considered acceptable use and where it draws the line – for example, young people whose brains are still developing. But she also points out a big problem: long-term safety studies in healthy people have never been done. Most efficacy studies have only been short-term. “Proving safety and efficacy is needed,” she says.
In the study, which evaluated the eating habits and mental ability of more than 950 older adults for an average of five years, those adults who ate a serving of leafy green veggies once or twice a day experienced slower mental deterioration than those who ate no vegetables, even when factors like age, education and family history of dementia were factored in.

Factor analysis. The strategy: read in the data, drop unnecessary data, impute missing variables (data is too heterogeneous and collected starting at varying intervals to be clean), estimate how many factors would fit best, factor analyze, pick the ones which look like they match best my ideas of what productive is, extract per-day estimates, and finally regress LLLT usage on the selected factors to look for increases.
“Most people assume that because it’s a supplement, it can’t be bad for you because it’s natural,” says Louis Kraus, M.D., a psychiatrist with Rush University Medical Center in Chicago. In 2016, he chaired a committee that investigated nootropics for the American Medical Association. After reviewing the science, the committee found little to no evidence to support the efficacy or safety of nootropics.
Powders are good for experimenting with (easy to vary doses and mix), but not so good for regular taking. I use OO gel capsules with a Capsule Machine: it’s hard to beat $20, it works, it’s not that messy after practice, and it’s not too bad to do 100 pills. However, I once did 3kg of piracetam + my other powders, and doing that nearly burned me out on ever using capsules again. If you’re going to do that much, something more automated is a serious question! (What actually wound up infuriating me the most was when capsules would stick in either the bottom or top try - requiring you to very gingerly pull and twist them out, lest the two halves slip and spill powder - or when the two halves wouldn’t lock and you had to join them by hand. In contrast: loading the gel caps could be done automatically without looking, after some experience.)
The nootropics community is surprisingly large and involved. When I wade into forums and the nootropics subreddit, I find members trading stack recipes and notifying each other of newly synthesized compounds. Some of these “psychonauts” seem like they’ve studied neuroscience; others appear to be novices dipping their toes into the world of cognitive enhancement. But all of them have the same goal: amplifying the brain’s existing capabilities without screwing anything up too badly. It’s the same impulse that grips bodybuilders—the feeling that with small chemical tweaks and some training, we can squeeze more utility out of the body parts we have. As Taylor Hatmaker of the Daily Dot recently wrote, “Together, these faceless armchair scientists seek a common truth—a clean, unharmful way to make their brains better—enforcing their own self-imposed safety parameters and painstakingly precise methods, all while publishing their knowledge for free, in plain text, to relatively crude, shared databases."
Avocados. Avocados are almost as good as blueberries in promoting brain health, says Pratt. "I don't think the avocado gets its due," agrees Kulze. True, the avocado is a fatty fruit, but, says Kulze, it's a monounsaturated fat, which contributes to healthy blood flow. "And healthy blood flow means a healthy brain," she says. Avocados also lower blood pressure, says Pratt, and as hypertension is a risk factor for the decline in cognitive abilities, a lower blood pressure should promote brain health. Avocados are high in calories, however, so Kulze suggests adding just 1/4 to 1/2 of an avocado to one daily meal as a side dish.
But like any other supplement, there are some safety concerns negative studies like Fish oil fails to hold off heart arrhythmia or other reports cast doubt on a protective effect against dementia or Fish Oil Use in Pregnancy Didn’t Make Babies Smart (WSJ) (an early promise but one that faded a bit later) or …Supplementation with DHA compared with placebo did not slow the rate of cognitive and functional decline in patients with mild to moderate Alzheimer disease..
Dr. Mosconi: I love apples. When I’m at the office though, I’ll bring homemade trail mix [made with] higher quality dried fruit, nuts and seeds. [It's] packed with brain-essential nutrients that come from goji berries, Brazil nuts, walnuts, cacao nibs, pistachios, hemp hearts and  more. Plus, I drink plenty of rose water throughout the day, which is very anti-inflammatory.
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.
Nootropics include natural and manmade chemicals that produce cognitive benefits. These substances are used to make smart pills that deliver results for enhancing memory and learning ability, improving brain function, enhancing the firing control mechanisms in neurons, and providing protection for the brain. College students, adult professionals, and elderly people are turning to supplements to get the advantages of nootropic substances for memory, focus, and concentration.

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).
A big part is that we are finally starting to apply complex systems science to psycho-neuro-pharmacology and a nootropic approach. The neural system is awesomely complex and old-fashioned reductionist science has a really hard time with complexity. Big companies spends hundreds of millions of dollars trying to separate the effects of just a single molecule from placebo – and nootropics invariably show up as “stacks” of many different ingredients (ours, Qualia , currently has 42 separate synergistic nootropics ingredients from alpha GPC to bacopa monnieri and L-theanine). That kind of complex, multi pathway input requires a different methodology to understand well that goes beyond simply what’s put in capsules.
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.

She provides many examples of observational studies where lower intakes of a certain nutrient were correlated with cognitive impairment. Obviously, if someone is deficient in a vitamin or other nutrient, the deficiency should be corrected. But she doesn’t have any evidence from prospective interventional studies showing that, in practice, altering diet significantly improves cognition for people who are deficient, much less in people who are not deficient.


Reason: More than 50 percent of your brain is comprised of DHA! Among a big group of elderly Americans, those with the highest blood levels of DHA were about half as apt to develop dementia and 39% as apt to develop Alzheimer’s as those with lower blood levels of DHA over a nine-year period. The top 25% of those with the highest blood DHA got about 180 mg DHA a day or three servings of fish a week, researchers said. In this study, the other major fatty acid in fish oil. EPA had no effect.
Of course, before wrapping up this section on psychedelics, I’ll address the topics of where to actually buy the stuff. There are a variety of websites that sell psychedelics, but not all ingredient, chemical or quality sourcing is created equal, nor is there any guarantee that any substance you are purchasing is not laced with undesirable compounds. Heck, I get my psilocybin from a farmer in Wisconsin who is a personal friend, and other ingredients from close acquaintances who have their own sources. I know it may seem unfair, but sometimes sourcing comes down to “who ya know” and doing your own due diligence on that person’s source.
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.
Interesting however, that there’s no mention of the power of cocoa (chocolate extract) or green tea. I’ve reviewed dozens of studies from Harvard Science as well as internation publications that discuss cocoa in particular. We already know the value of antioxidants in green tea but chocolate seems to be up and coming. I’ve been taking a product called vavalert that combines cocoa and green tea and it’s been working like a miracle.

Last April the scientific journal Nature published the results of an informal online poll asking whether readers attempted to sharpen "their focus, concentration, or memory" by taking drugs such as Ritalin and Provigil, a newer kind of stimulant, known generically as modafinil, which was developed to treat narcolepsy. One in five respondents said they did. A majority of the 1,400 readers who responded said that healthy adults should be permitted to take brain boosters for non-medical reasons, and 69% said that mild side-effects were an acceptable risk. Though a majority said that such drugs should not be made available to children who had no diagnosed medical condition, a third admitted that they would feel pressure to give "smart drugs" to their kids if they learned that other parents were doing so.
Starting from the studies in my meta-analysis, we can try to estimate an upper bound on how big any effect would be, if it actually existed. One of the most promising null results, Southon et al 1994, turns out to be not very informative: if we punch in the number of kids, we find that they needed a large effect size (d=0.81) before they could see anything:
“It is surprising and encouraging that it may be possible to predict the magnitude of a placebo effect before treatment,” says Tor Wager, a neuroscientist at the University of Colorado Boulder, who was not involved in the research. More work is needed to see how the predictive features hold up in other populations and for different pain conditions, he says.
The nootropic sulbutiamine, of the synthetic B-vitamin-derived nootropics family, is generally considered a low-risk supplement; however, some users have reported that the supplement has addictive qualities. While there is no firm evidence of sulbutiamine addiction, the risk may increase at high dosages. For instance, users who consume this supplement for 10 consecutive days may experience withdrawal for two to five days. There are also increased risks when sulbutiamine is taken with antipsychotic medications.[8]
Took random pill at 2:02 PM. Went to lunch half an hour afterwards, talked until 4 - more outgoing than my usual self. I continued to be pretty energetic despite not taking my caffeine+piracetam pills, and though it’s now 12:30 AM and I listened to TAM YouTube videos all day while reading, I feel pretty energetic and am reviewing Mnemosyne cards. I am pretty confident the pill today was Adderall. Hard to believe placebo effect could do this much for this long or that normal variation would account for this. I’d say 90% confidence it was Adderall. I do some more Mnemosyne, typing practice, and reading in a Montaigne book, and finally get tired and go to bed around 1:30 AM or so. I check the baggie when I wake up the next morning, and sure enough, it had been an Adderall pill. That makes me 1 for 2.
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.)
I’ve been taking nootropics on and off for a month, and despite my spurts of productivity, I’m still not 100 percent sure that they’re working. I could well be placebo-ing myself into thinking I'm working harder and focusing better than I typically do. But apparently enough people are feeling some effect, placebo or not, because nootropics start-ups are thriving. There’s truBrain, Nootrobrain, Nootroo, and a host of others. Nootrobox, the company that makes my pills, says that it’s selling "five figures" worth of cognitive supplements monthly to customers that include top Silicon Valley executives and Hollywood moguls.
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.
This research is in contrast to the other substances I like, such as piracetam or fish oil. I knew about withdrawal of course, but it was not so bad when I was drinking only tea. And the side-effects like jitteriness are worse on caffeine without tea; I chalk this up to the lack of theanine. (My later experiences with theanine seems to confirm this.) These negative effects mean that caffeine doesn’t satisfy the strictest definition of nootropic (having no negative effects), but is merely a cognitive enhancer (with both benefits & costs). One might wonder why I use caffeine anyway if I am so concerned with mental ability.
My answer is that this is not a lot of research or very good research (not nearly as good as the research on nicotine, eg.), and assuming it’s true, I don’t value long-term memory that much because LTM is something that is easily assisted or replaced (personal archives, and spaced repetition). For me, my problems tend to be more about akrasia and energy and not getting things done, so even if a stimulant comes with a little cost to long-term memory, it’s still useful for me. I’m going continue to use the caffeine. It’s not so bad in conjunction with tea, is very cheap, and I’m already addicted, so why not? Caffeine is extremely cheap, addictive, has minimal effects on health (and may be beneficial, from the various epidemiological associations with tea/coffee/chocolate & longevity), and costs extra to remove from drinks popular regardless of their caffeine content (coffee and tea again). What would be the point of carefully investigating it? Suppose there was conclusive evidence on the topic, the value of this evidence to me would be roughly $0 or since ignorance is bliss, negative money - because unless the negative effects were drastic (which current studies rule out, although tea has other issues like fluoride or metal contents), I would not change anything about my life. Why? I enjoy my tea too much. My usual tea seller doesn’t even have decaffeinated oolong in general, much less various varieties I might want to drink, apparently because de-caffeinating is so expensive it’s not worthwhile. What am I supposed to do, give up my tea and caffeine just to save on the cost of caffeine? Buy de-caffeinating machines (which I couldn’t even find any prices for, googling)? This also holds true for people who drink coffee or caffeinated soda. (As opposed to a drug like modafinil which is expensive, and so the value of a definitive answer is substantial and would justify some more extensive calculating of cost-benefit.)
2 commenters point out that my possible lack of result is due to my mistaken assumption that if nicotine is absorbable through skin, mouth, and lungs it ought to be perfectly fine to absorb it through my stomach by drinking it (rather than vaporizing it and breathing it with an e-cigarette machine) - it’s apparently known that absorption differs in the stomach.
Brain Awake is produced by Irwin Naturals. The ingredients are natural and include some key ingredients. However, it also contained several other inactive ingredients that raised some concerns - namely, beeswax and silicone dioxide. We were not sure why these ingredients are included, and could not find any real explanation as to why they are contained within this product. That said, when we tested the ingredients in this product, they were as reported on the bottle.
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.
Of course learning, working memory and cognitive control represent just a few aspects of thinking. Farah concluded that studies looking at other kinds of cognition - verbal fluency, for instance - were too few and too contradictory to tell us much. Both Chatterjee and Farah have wondered whether drugs that heighten users' focus might dampen their creativity. After all, some of our best ideas come to us not when we sit down at a desk but rather when we're in the shower or walking the dog - letting our minds roam. Jimi Hendrix reported that the inspiration for "Purple Haze" came to him in a dream; the chemist Friedrich August Kekule claimed that he discovered the ring structure of benzene during a reverie in which he saw the image of a snake biting its tail. Farah told me: "There is some evidence that suggests that individuals who are better able to focus on one thing and filter out distractions tend to be less creative.
Tempted to skip breakfast? Studies have found that eating breakfast may improve short-term memory and attention. Students who eat it tend to perform better than those who don’t. Foods at the top of researchers' brain-fuel list include high-fiber whole grains, dairy, and fruits. Just don't overeat; researchers also found high-calorie breakfasts appear to hinder concentration.
Taking these drugs without a doctor’s supervision can be dangerous. There are interactions and contraindications that can cause serious problems. These drugs should not be used if you drink alcohol or take an antidepressant. (50) The possibility of adverse drug reactions should not be taken lightly. By some calculations, adverse drug reactions are now the fourth leading cause of death in the US. (51)
Vinh Ngo, a San Francisco family practice doctor who specializes in hormone therapy, has become familiar with piracetam and other nootropics through a changing patient base. His office is located in the heart of the city’s tech boom and he is increasingly sought out by young, male tech workers who tell him they are interested in cognitive enhancement.
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.
[…] The verdict is out on brain health and aging. Scientists now know that memory loss and cognitive decline are not an inevitable part of growing older. In fact, the research proves quite the contrary. You can keep your mind sharp well into old age with a strategy that combines a healthy, active lifestyle with a brain-protecting diet and brain-boosting supplements. […]
Last spring, 100 people showed up at a Peak Performance event where psychedelic psychologist James Fadiman said the key to unleashing the cognition-enhancing effects of LSD — which he listed as less anxiety, better focus, improved sleep, greater creativity — was all in the dosage. He recommended a tenth of a “party dose” — enough to give you “the glow” and enhance your cognitive powers without “the trip.”
It is important that this type of approach is discussed with a qualified health professional, such as a registered nutritional therapist, to ensure it is an appropriate strategy for you, as well as to help you avoid missing out on vital nutrients, whilst eliminating certain foods. They can also provide advice on improving your longer term health, which over time may allow for foods to be reintroduced without negative symptoms occurring.
A key area that has been widely researched is the link between the microbiome (bacteria) in the gut and the brain. The hypothesis is that alterations in bacteria due to changes in our environment such as increased hygiene, increased exposure to antibiotics, refined and processed foods and stress have led to disturbances in short-chain fatty acids (SFCAs), which are byproducts of fermentation in the gut when bacteria come into contact with indigestible fibre found in food.
Capsule Connection sells 1000 00 pills (the largest pills) for $9. I already have a pill machine, so that doesn’t count (a sunk cost). If we sum the grams per day column from the first table, we get 9.75 grams a day. Each 00 pill can take around 0.75 grams, so we need 13 pills. (Creatine is very bulky, alas.) 13 pills per day for 1000 days is 13,000 pills, and 1,000 pills is $9 so we need 13 units and 13 times 9 is $117.
Ngo has experimented with piracetam himself (“The first time I tried it, I thought, ‘Wow, this is pretty strong for a supplement.’ I had a little bit of reflux, heartburn, but in general it was a cognitive enhancer. . . . I found it helpful”) and the neurotransmitter DMEA (“You have an idea, it helps you finish the thought. It’s for when people have difficulty finishing that last connection in the brain”).

the larger size of the community enables economies of scale and increases the peak sophistication possible. In a small nootropics community, there is likely to be no one knowledgeable about statistics/experimentation/biochemistry/neuroscience/whatever-you-need-for-a-particular-discussion, and the available funds increase: consider /r/Nootropics’s testing program, which is doable only because it’s a large lucrative community to sell to so the sellers are willing to donate funds for independent lab tests/Certificates of Analysis (COAs) to be done. If there were 1000 readers rather than 23,295, how could this ever happen short of one of those 1000 readers being very altruistic?
A passionate singer, yogi, and vegan baker, you can usually count on Jessica to be writing songs, inventing recipes, or doing handstands. Most notably, Jessica is recognized (by her parents) for a 3 minute vocal solo at Carnegie Hall (at 13), by her friends for her amazing Raw Vegan Peanut Butter Chocolate Chip Cookie recipe, and also by her yogi friends for her recent mastery of Camel Pose. In all seriousness, Jessica is beyond excited to write for SnackNation, and to share her passion for health, wellness, and delicious foods.

Chatterjee told me that many people who come to his clinic are cognitively preoccupied versions of what doctors call the "worried well". He had just seen a middle-aged woman, a successful Philadelphia lawyer, who mentioned having to struggle a bit to come up with certain names. "Here's an example of someone who by most measures is doing perfectly fine," Chatterjee said. "She's not having any trouble at work. But she notices she's having some problems, and it's very hard to know how much of that is just getting older." Of course, people in her position could strive to get regular exercise and plenty of intellectual stimulation, both of which have been shown to help maintain cognitive function. But maybe they're already doing so and want a bigger mental rev-up, or maybe they want something easier than sweaty workouts and Russian novels: they want a pill.

Our brain supplement promotes better concentration and improved focus to help you excel at work or school. In addition, our focus supplement aids in brain health throughout life for clearer thinking and memory support.
I can’t try either of the products myself – I am pregnant and my doctor doesn’t recommend it – but my husband agrees to. He describes the effect of the Nootrobox product as like having a cup of coffee but not feeling as jittery. “I had a very productive day, but I don’t know if that was why,” he says. His Nootroo experience ends after one capsule. He gets a headache, which he is convinced is related, and refuses to take more. “It is just not a beginner friendly cocktail,” offers Noehr.

In fact, this body-mind connection has become so relevant to our current era that communities like Mental Health America are devoting their efforts to create a challenge that raises awareness on how lifestyle plays an important role on our mental health. While our generation is definitely more conscious of our bodies and the importance of a healthy lifestyle, it's a good reminder that the body is like a machine and we should listen to it, tune it up, and update the system every so often. 
Panax ginseng – A review by the Cochrane Collaboration concluded that "there is a lack of convincing evidence to show a cognitive enhancing effect of Panax ginseng in healthy participants and no high quality evidence about its efficacy in patients with dementia."[36] According to the National Center for Complementary and Integrative Health, "[a]lthough Asian ginseng has been widely studied for a variety of uses, research results to date do not conclusively support health claims associated with the herb."[37]
