A total of 330 randomly selected Saudi adolescents were included. Anthropometrics were recorded and fasting blood samples were analyzed for routine analysis of fasting glucose, lipid levels, calcium, albumin and phosphorous. Frequency of coffee and tea intake was noted. 25-hydroxyvitamin D levels were measured using enzyme-linked immunosorbent assays…Vitamin D levels were significantly highest among those consuming 9-12 cups of tea/week in all subjects (p-value 0.009) independent of age, gender, BMI, physical activity and sun exposure.

Alex remains enthusiastic about Adderall, but he also has a slightly jaundiced critique of it. "It only works as a cognitive enhancer insofar as you are dedicated to accomplishing the task at hand," he said. "The number of times I've taken Adderall late at night and decided that, rather than starting my paper, hey, I'll organise my entire music library! I've seen people obsessively cleaning their rooms on it." Alex thought that generally the drug helped him to bear down on his work, but it also tended to produce writing with a characteristic flaw. "Often I've looked back at papers I've written on Adderall, and they're verbose. They're labouring a point, trying to create this airtight argument. I'd produce two pages on something that could be said in a couple of sentences." Nevertheless, his Adderall-assisted papers usually earned him at least a B. They got the job done. As Alex put it: "Productivity is a good thing."
In fact, many nerve gas agents act similarly to Huperzia serrata by blocking the enzyme that breaks down acetylcholine. But research has shown that in smaller doses, Huperzine A, the extract of Huperzia serrata used in nootropics, would likely offer some protection against damage from nerve agents. That the same substance can act as a nerve agent, protect against nerve agents, and give you crazy dreams, underscores how important it is to stay within the recommended doses.
As it happens, these are areas I am distinctly lacking in. When I first began reading about testosterone I had no particular reason to think it might be an issue for me, but it increasingly sounded plausible, an aunt independently suggested I might be deficient, a biological uncle turned out to be severely deficient with levels around 90 ng/dl (where the normal range for 20-49yo males is 249-839), and finally my blood test in August 2013 revealed that my actual level was 305 ng/dl; inasmuch as I was 25 and not 49, this is a tad low.

DNB-wise, eyeballing my stats file seems to indicate a small increase: when I compare peak scores D4B scores, I see mostly 50s and a few 60s before piracetam, and after starting piracetam, a few 70s mixed into the 50s and 60s. Natural increase from training? Dunno - I’ve been stuck on D4B since June, so 5 or 10% in a week or 3 seems a little suspicious. A graph of the score series27:
The NIDA research study focused on 10 healthy male participants. The men were subjected to two rounds of PET brain scans after consuming either Provigil (200 mg or 400 mg) or a placebo. The scans demonstrated that the Provigil users had an increase in the amount of dopamine in the brain. Dopamine is a key neurological messenger in the brain’s reward system. Cocaine and methamphetamine have a similar effect on the brain, but they are more potent and faster-acting than Provigil. As cocaine and amphetamines are addiction-forming, the reasoning here is that Provigil may also be addictive.

Lucas Baker, a Switzerland-based software engineer with a large tech company, takes nootropics every day. He says it helps him maintain focus, especially on projects he might otherwise put off. “When I find an unpleasant task, I can just power through it,” he says. Baker also makes the coffee comparison: “There’s already a universally-embraced nootropic called caffeine,” he says. “It’s just about making it more widely researched.”

After I ran out of creatine, I noticed the increased difficulty, and resolved to buy it again at some point; many months later, there was a Smart Powders sale so bought it in my batch order, $12 for 1000g. As before, it made Taekwondo classes a bit easier. I paid closer attention this second time around and noticed that as one would expect, it only helped with muscular fatigue and did nothing for my aerobic issues. (I hate aerobic exercise, so it’s always been a weak point.) I eventually capped it as part of a sulbutiamine-DMAE-creatine-theanine mix. This ran out 1 May 2013. In March 2014, I spent $19 for 1kg of micronized creatine monohydrate to resume creatine use and also to use it as a placebo in a honey-sleep experiment testing Seth Roberts’s claim that a few grams of honey before bedtime would improve sleep quality: my usual flour placebo being unusable because the mechanism might be through simple sugars, which flour would digest into. (I did not do the experiment: it was going to be a fair amount of messy work capping the honey and creatine, and I didn’t believe Roberts’s claims for a second - my only reason to do it would be to prove the claim wrong but he’d just ignore me and no one else cares.) I didn’t try measuring out exact doses but just put a spoonful in my tea each morning (creatine is tasteless). The 1kg lasted from 25 March to 18 September or 178 days, so ~5.6g & $0.11 per day.
The evidence? Ritalin is FDA-approved to treat ADHD. It has also been shown to help patients with traumatic brain injury concentrate for longer periods, but does not improve memory in those patients, according to a 2016 meta-analysis of several trials. A study published in 2012 found that low doses of methylphenidate improved cognitive performance, including working memory, in healthy adult volunteers, but high doses impaired cognitive performance and a person’s ability to focus. (Since the brains of teens have been found to be more sensitive to the drug’s effect, it’s possible that methylphenidate in lower doses could have adverse effects on working memory and cognitive functions.)
At this point I began to get bored with it and the lack of apparent effects, so I began a pilot trial: I’d use the LED set for 10 minutes every few days before 2PM, record, and in a few months look for a correlation with my daily self-ratings of mood/productivity (for 2.5 years I’ve asked myself at the end of each day whether I did more, the usual, or less work done that day than average, so 2=below-average, 3=average, 4=above-average; it’s ad hoc, but in some factor analyses I’ve been playing with, it seems to load on a lot of other variables I’ve measured, so I think it’s meaningful).
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.

She reveals where she went astray. In a lecture she gave, she lamented the failure of science to offer a cure for Alzheimer’s or even an effective treatment. Someone in the audience asked, “How about olive oil?” She realized she didn’t know anything about the effects of nutrition on Alzheimer’s. She seems to have assumed that diet must be crucially important, and for some reason instead of studying conventional nutrition science, she got a degree in Holistic Nutrition. She bills herself as a certified Integrative Nutritionist and holistic healthcare practitioner. I couldn’t find where she studied, but Stephen Barrett has criticized the Institute for Integrative Nutrition on Quackwatch. Its training is not based on scientific nutrition. It seems most programs in Integrative Nutrition are 6- to 8-month correspondence courses with no prerequisites. I wonder what she was taught.

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.

This calculation - reaping only \frac{7}{9} of the naive expectation - gives one pause. How serious is the sleep rebound? In another article, I point to a mice study that sleep deficits can take 28 days to repay. What if the gain from modafinil is entirely wiped out by repayment and all it did was defer sleep? Would that render modafinil a waste of money? Perhaps. Thinking on it, I believe deferring sleep is of some value, but I cannot decide whether it is a net profit.
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).

Some nootropics users are hopeful that the drugs could be permanently “neuroprotective”—in other words, that the compounds could slow down the neuronal aging process, and help avoid cognitive deterioration later in life. (For what it's worth, most of the users I spoke to said that didn't matter much to them. “I doubt anything I’ve tried has made me smarter in a long-term way,” Baker says. “That’s still science fiction.”)

L-Alpha glycerylphosphorylcholine or choline alfoscerate, also known as Alpha GPC is a natural nootropic which works both on its own and also in combination with other nootropics. It can be found in the human body naturally in small amounts. It’s also present in some dairy products, wheat germ, and in organic meats. However, these dietary sources contain small amounts of GPC, which is why people prefer taking it through supplements.
I almost resigned myself to buying patches to cut (and let the nicotine evaporate) and hope they would still stick on well enough afterwards to be indistinguishable from a fresh patch, when late one sleepless night I realized that a piece of nicotine gum hanging around on my desktop for a week proved useless when I tried it, and that was the answer: if nicotine evaporates from patches, then it must evaporate from gum as well, and if gum does evaporate, then to make a perfect placebo all I had to do was cut some gum into proper sizes and let the pieces sit out for a while. (A while later, I lost a piece of gum overnight and consumed the full 4mg to no subjective effect.) Google searches led to nothing indicating I might be fooling myself, and suggested that evaporation started within minutes in patches and a patch was useless within a day. Just a day is pushing it (who knows how much is left in a useless patch?), so I decided to build in a very large safety factor and let the gum sit for around a month rather than a single day.
Although research linking diet and dementia is still in its infancy, there are a few important relationships between nutrients and brain health that are worth exploring. Having a nourishing, well rounded diet gives our brain the best chance of avoiding disease. If your diet is unbalanced for whatever reason, you may want to consider a multivitamin and mineral complex and an omega-3 fatty acid supplement to help make up a few of the essentials. If you are considering taking a supplement it is best to discuss this with your GP or qualified healthcare professional.
In my last post, I talked about the idea that there is a resource that is necessary for self-control…I want to talk a little bit about the candidate for this resource, glucose. Could willpower fail because the brain is low on sugar? Let’s look at the numbers. A well-known statistic is that the brain, while only 2% of body weight, consumes 20% of the body’s energy. That sounds like the brain consumes a lot of calories, but if we assume a 2,400 calorie/day diet - only to make the division really easy - that’s 100 calories per hour on average, 20 of which, then, are being used by the brain. Every three minutes, then, the brain - which includes memory systems, the visual system, working memory, then emotion systems, and so on - consumes one (1) calorie. One. Yes, the brain is a greedy organ, but it’s important to keep its greediness in perspective… Suppose, for instance, that a brain in a person exerting their willpower - resisting eating brownies or what have you - used twice as many calories as a person not exerting willpower. That person would need an extra one third of a calorie per minute to make up the difference compared to someone not exerting willpower. Does exerting self control burn more calories?
And when it comes to your brain, it’s full of benefits, too. Coconut oil works as a natural anti-inflammatory, suppressing cells responsible for inflammation. It can help with memory loss as you age and destroy bad bacteria that hangs out in your gut. (5) Get your dose of coconut oil in this Baked Grouper with Coconut Cilantro Sauce or Coconut Crust Pizza.
I tried taking whole pills at 1 and 3 AM. I felt kind of bushed at 9 AM after all the reading, and the 50 minute nap didn’t help much - I was sleep only around 10 minutes and spent most of it thinking or meditation. Just as well the 3D driver is still broken; I doubt the scores would be reasonable. Began to perk up again past 10 AM, then felt more bushed at 1 PM, and so on throughout the day; kind of gave up and began watching & finishing anime (Amagami and Voices of a Distant Star) for the rest of the day with occasional reading breaks (eg. to start James C. Scotts Seeing Like A State, which is as described so far). As expected from the low quality of the day, the recovery sleep was bigger than before: a full 10 hours rather than 9:40; the next day, I slept a normal 8:50, and the following day ~8:20 (woken up early); 10:20 (slept in); 8:44; 8:18 (▁▇▁▁). It will be interesting to see whether my excess sleep remains in the hour range for ’good modafinil nights and two hours for bad modafinil nights.
So where did the idea of Blue Monday come from? The concept of Blue Monday was originally coined by Dr Cliff Arnall in 2005 and distributed by the PR company Sky Travel. It has now become an annual event and can fall on either the third or the fourth Monday of January, using Dr Cliff Arnall’s original mathematical equation that measures a combination of factors such as weather, potential debt post-Christmas, the amount of time since Christmas, potential failure of New Year resolutions and motivation levels, that apparently conspire to make the date the gloomiest of the year.
It doesn't take a neuroscientist with a degree in nutrition to get that diet can affect the brain. It does take a neuroscientist with a degree in nutrition to provide such a smart research-driven analysis of how and to what extent. Brain Food is based on the work of literally hundreds of scientists and provides a dietary roadmap to enhanced cognitive power. That Dr. Mosconi's book is also fully accessible to a layperson makes this a true must read. (Bonus: Chapter 16 is a mini-cookbook with "brain boosting" recipes including several that are kid-friendly.)
Celastrus paniculatus, also known as the Intellect Tree, is perhaps one of the more interesting Ayurvedic medicinal plants that has been used for thousands of years, and one that I personally use quite frequently as part of the supplement “Qualia Mind”. In the Ayurvedic tradition, oil derived from C. paniculatus (Malkanguni oil) is used to enhance memory and intellectual capacity, as well as to improve dream recall and induce lucid dreams. In a study performed on healthy rats, the oil was shown to improve 24-hour memory retention after a single dose, an effect accompanied by a reduction in monoamines like norepinephrine, dopamine and serotonin, indicating a decreased turnover of these neurotransmitters which, in turn, may aid in reducing conditions like depression. In another study with rats, C. paniculatus oil administered for 14 days reversed stress-induced spatial learning and memory impairment and restored working memory. In mice with scopolamine-induced memory deficits, the oil has been shown to improve both spatial and fear memory (a type of fear conditioning through which an organism learns to avoid detrimental situations or events). Traditionally, is taken in seed form, starting with 10 seeds and working up to 15 and finally 20 seeds.
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.
This is why it was so refreshing to stumble across Dr. Lisa Mosconi's new book "Brain Food: The Surprising Power of Eating for Cognitive Power" . "Our brains aren't keeping up with the historical change in dietary consumptions", says Dr. Lisa. And it's quite evident in her book when she does a historical overview and draws an important relationship between what our ancestors were eating and the concept of longevity. Her contribution to the fascinating new world of "neuro-nutrition" differs drastically from the diet culture we are all so used to and can help us understand why including (and excluding) certain foods, will actually boost our brain health. 
The U. S. nootropics industry was valued at more than $1.3 billion in 2015 and is projected to reach $6 billion by 2024. This growth is due in part to slick marketing from biohacking “experts” such as Dave Asprey (founder of Bulletproof) and Josiah Zayner, Ph.D. (CEO of the Odin), who’ve built big social-media and podcast followings as well as customer bases. At the grassroots level, there are meetups across the country like the one at Idea Coffee, plus a vibrant online community.
Nootropics That is offered through an email showing Ben Carson and Bill O Reily talking about it and they offer a deal the more you buy the cheaper it is with free bottles is a scam. I ordered 3 bottles with 2 free and free shipping which should have been 120.00. They had a offer for 59.99 for cleansing product and I didn’t order it. My total came out to 189.94. I called them and they removed it and then the 5 bottles was still going to be 189.99. I told them about the offer and they would not honor it. I ended up canceling the order. This is a scam!!
Microdosing involves ingesting small amounts of psychedelics to induce a very subtle physical and mental effect accompanied by a very noticeable, overall positive, health effect. When you take a microdose of a psychedelic, it is typically referred to as a sub-perceptual dose. A sub-perceptual dose will not have a major impact on your ability to function normally, but the effect will definitely be present in your mood and behavior. The microdose of a particular psychedelic is correlated to the lowest dose that will produce a noticeable effect, which is also known as the threshold dose. Since the goal is not to get a hallucinogenic effect, a microdose can be well below the psychedelics threshold dose. By integrating the correct doses of psychedelics into your weekly routine, you can achieve higher creativity levels, more energy, improved mood, increased focus, and better relational skills. There is a growing body of research that shows microdosing to improve depression, anxiety, PTSD, and emotional imbalance, help with alcohol and tobacco addiction, and decrease ADD and ADHD behaviors.

Such competitive anxieties are already being felt in the workplace. Recently an advice column in Wired featured a question from a reader worried about "a rising star at the firm" who was "using unprescribed modafinil to work crazy hours. Our boss has started getting on my case for not being as productive." And on internet forums such as ImmInst (Immortality Institute), whose members share a nerdy passion for tweaking their cognitive function through drugs and supplements, people trade advice about dosages and "stacks" - improvised combinations - of neuroenhancers ("Cut a tablet into fourths and took 25mg every four hours, four times today, and had a great and productive day - with no side-effects"). In one recent post a 52-year-old - who was working full time, studying for an advanced degree at night and "married, etc" - wrote that after experimenting with modafinil he had settled on two daily doses of 100mg each. He believed that he was "performing a little better", adding: "I also feel slightly more animated when in discussion."

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.

(On a side note, I think I understand now why modafinil doesn’t lead to a Beggars in Spain scenario; BiS includes massive IQ and motivation boosts as part of the Sleepless modification. Just adding 8 hours a day doesn’t do the world-changing trick, no more than some researchers living to 90 and others to 60 has lead to the former taking over. If everyone were suddenly granted the ability to never need sleep, many of them would have no idea what to do with the extra 8 or 9 hours and might well be destroyed by the gift; it takes a lot of motivation to make good use of the time, and if one cannot, then it is a curse akin to the stories of immortals who yearn for death - they yearn because life is not a blessing to them, though that is a fact more about them than life.)
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:
Nootropics still exist largely in an unregulated gray area, which makes users somewhat hesitant to discuss their regimens. But I did speak to several people who told tales of increased productivity and sharpened focus. Bob Carter, a financial analyst for a start-up called LendingHome, says that nootropics have replaced his other morning stimulant. “I basically think of it as a substitute for coffee,” he says. “I think the problem with a cappuccino from Starbucks is that it gives you the feeling of being jittery. Whereas with this particular supplement, I feel more calm.”
A new all-in-one nootropic mix/company run by some people active on /r/nootropics; they offered me a month’s supply for free to try & review for them. At ~$100 a month (it depends on how many months one buys), it is not cheap (John Backus estimates one could buy the raw ingredients for $25/month) but it provides convenience & is aimed at people uninterested in spending a great deal of time reviewing research papers & anecdotes or capping their own pills (ie. people with lives) and it’s unlikely I could spare the money to subscribe if TruBrain worked well for me - but certainly there was no harm in trying it out.
Growing up, Joe was plagued with a myriad of health issues such as gut problems, autoimmune issues, chronic fatigue, brain fog, insomnia, and general inflammation. Both conventional and alternative doctors weren’t able to help him, so he decided to fix himself. With lots of health questions and few satisfying answers, Joe decided to read every research paper he could get his hands on and conduct thousands of experiments on his own body in order to fix his health issues. Joe started SelfHacked in late 2013 when he successfully fixed all of his issues, and now it gets millions of readers a month looking to educate themselves about how they can improve their health. Joe is now a thriving author, speaker, and serial entrepreneur, founding SelfDecode & LabTestAnalyzer.
Qualia Mind, meanwhile, combines more than two dozen ingredients that may support brain and nervous system function – and even empathy, the company claims – including vitamins B, C and D, artichoke stem and leaf extract, taurine and a concentrated caffeine powder. A 2014 review of research on vitamin C, for one, suggests it may help protect against cognitive decline, while most of the research on artichoke extract seems to point to its benefits to other organs like the liver and heart. A small company-lead pilot study on the product found users experienced improvements in reasoning, memory, verbal ability and concentration five days after beginning Qualia Mind.
