These days, nootropics are beginning to take their rightful place as a particularly powerful tool in the Neurohacker’s toolbox. After all, biochemistry is deeply foundational to neural function. Whether you are trying to fix the damage that is done to your nervous system by a stressful and toxic environment or support and enhance your neural functioning, getting the chemistry right is table-stakes. And we are starting to get good at getting it right. What’s changed?
Woo understands that when selling brain drugs, skepticism comes with the territory. "The typical first reaction is, this is bullshit, you guys are snake-oil salesmen," he says. "We're not medical doctors nor biochemistry experts, but we are experts in building teams and building products. Like how Elon Musk attacks rockets and electric cars from 'first principles,' we see ourselves as applying Silicon Valley aesthetics and operational know-how to the murky world of nootropics."
A week later: Golden Sumatran, 3 spoonfuls, a more yellowish powder. (I combined it with some tea dregs to hopefully cut the flavor a bit.) Had a paper to review that night. No (subjectively noticeable) effect on energy or productivity. I tried 4 spoonfuls at noon the next day; nothing except a little mental tension, for lack of a better word. I think that was just the harbinger of what my runny nose that day and the day before was, a head cold that laid me low during the evening.
Your co-worker in the cubicle next to you could now very likely be achieving his or her hyperfocus via a touch of microdosed LSD, a hit of huperzine or a nicotine-infused arm patch. The fact is, concepts such as microdosing, along with words like “nootropic” and “smart drug” (yes, there’s a difference between the two, as you’re about to discover) are quickly becoming household terms, especially due to all the recent media hype that has disclosed how popular compounds such as smart drugs and psychedelics are among Silicon Valley CEOs and college students, along with the smart drug movies “Limitless” and “Lucy“ and popular TV shows like “Limitless”, “Wormwood” and “Hamilton’s Pharmacopeia”.
There are plenty of brain supplements on the market, but none with the same combinations of potent and promising ingredients. If you want to maximize your ability to excel  – at everything you do – your brain must be firing on all cylinders – all day, every day. You must protect and preserve your brain function, as it will diminish – it’s the reality of being human.

Your brain is essentially a network of billions of neurons connected by synapses. These neurons communicate and work together through chemicals known as neurotransmitters. When neurotransmitters are able to send signals more efficiently, you experience improved concentration, better memory, mood elevation, increased processing ability for mental work, and longer attention spans.

At small effects like d=0.07, a nontrivial chance of negative effects, and an unknown level of placebo effects (this was non-blinded, which could account for any residual effects), this strongly implies that LLLT is not doing anything for me worth bothering with. I was pretty skeptical of LLLT in the first place, and if 167 days can’t turn up anything noticeable, I don’t think I’ll be continuing with LLLT usage and will be giving away my LED set. (Should any experimental studies of LLLT for cognitive enhancement in healthy people surface with large quantitative effects - as opposed to a handful of qualitative case studies about brain-damaged people - and I decide to give LLLT another try, I can always just buy another set of LEDs: it’s only ~$15, after all.)
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.

There are many studies that suggest that Creatine helps in treating cognitive decline in individuals when combined with other therapies. It also helps people suffering from Parkinsons and Huntingtons disease. Though there are minimal side effects associated with creatine, pretty much like any nootropic, it is not  absolutely free of side-effects. An overdose of creatine can lead to gastrointestinal issues, weight gain, stress and anxiety.
Colorful vegetables and fruits—such as leafy greens, peppers, beets, and berries—are high in carotenoids and anthocyanins, antioxidant pigments that provide their bright hues. “Antioxidants protect brain cell linings from the damage caused by free radicals, which are harmful molecules that cause inflammation and result from factors like a poor diet or smoking,” explains Janis Jibrin, RD, adjunct professor of nutrition at American University in Washington, D.C.
The amphetamine mix branded Adderall is terribly expensive to obtain even compared to modafinil, due to its tight regulation (a lower schedule than modafinil), popularity in college as a study drug, and reportedly moves by its manufacture to exploit its privileged position as a licensed amphetamine maker to extract more consumer surplus. I paid roughly $4 a pill but could have paid up to $10. Good stimulant hygiene involves recovery periods to avoid one’s body adapting to eliminate the stimulating effects, so even if Adderall was the answer to all my woes, I would not be using it more than 2 or 3 times a week. Assuming 50 uses a year (for specific projects, let’s say, and not ordinary aimless usage), that’s a cool $200 a year. My general belief was that Adderall would be too much of a stimulant for me, as I am amphetamine-naive and Adderall has a bad reputation for letting one waste time on unimportant things. We could say my prediction was 50% that Adderall would be useful and worth investigating further. The experiment was pretty simple: blind randomized pills, 10 placebo & 10 active. I took notes on how productive I was and the next day guessed whether it was placebo or Adderall before breaking the seal and finding out. I didn’t do any formal statistics for it, much less a power calculation, so let’s try to be conservative by penalizing the information quality heavily and assume it had 25%. So \frac{200 - 0}{\ln 1.05} \times 0.50 \times 0.25 = 512! The experiment probably used up no more than an hour or two total.
A Romanian psychologist and chemist named Corneliu Giurgea started using the word nootropic in the 1970s to refer to substances that improve brain function, but humans have always gravitated toward foods and chemicals that make us feel sharper, quicker, happier, and more content. Our brains use about 20 percent of our energy when our bodies are at rest (compared with 8 percent for apes), according to National Geographic, so our thinking ability is directly affected by the calories we’re taking in as well as by the nutrients in the foods we eat. Here are the nootropics we don’t even realize we’re using, and an expert take on how they work.
Either prescription or illegal, daily use of testosterone would not be cheap. On the other hand, if I am one of the people for whom testosterone works very well, it would be even more valuable than modafinil, in which case it is well worth even arduous experimenting. Since I am on the fence on whether it would help, this suggests the value of information is high.
One reason I like modafinil is that it enhances dopamine release, but it binds to your dopamine receptors differently than addictive substances like cocaine and amphetamines do, which may be part of the reason modafinil shares many of the benefits of other stimulants but doesn’t cause addiction or withdrawal symptoms. [3] [4] It does increase focus, problem-solving abilities, and wakefulness, but it is not in the same class of drugs as Adderall, and it is not a classical stimulant. Modafinil is off of patent, so you can get it generically, or order it from India. It’s a prescription drug, so you need to talk to a physician.
Apart from the risks that accompany drugs with dopaminergic effects, amphetamines, even when used to treat neurological disorders like ADHD, have been known to frequently and predictably cause anorexia, weight loss and insomnia. High doses can cause psychotic behavior, and even normal doses have been known to produce psychosis that ranged from the loss of short-term memory to horrific visual and auditory hallucinations. Are you getting the impression that using synthetic stimulants to flood your brain short-term with excessive or unnaturally high levels of hormones and neurotransmitters may not be a good idea, especially when done frequently or in excess?
At this point, I discovered I had run out of magnesium pills and had forgotten to order the magnesium citrate powder I’d intended to. I still had a lot of Noopept pills for the concurrently running second Noopept self-experiment, but since I wanted to wrap up some other experiments with a big analysis at the end of the year, I decided to halt and resume in January 2014.
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.
A study published in the Journal of Environmental Healths Perspective stated that "researchers, physicians, and others poked around in the dark crevices of the gene, (are) trying to untangle the clues that suggested gene function could be altered by more than just changes in sequence." This ties in perfectly with what Dr. Lisa mentions about how our lifestyles play a crucial role in how/if we manifest a certain cognitive disfunction. Which brings us to our next question: What kind of "brain diet" can help support this lifestyle?
Tomatoes - does that include tinned? And what about passata? And while we are at it, are frozen veg as good [or very nearly] as fresh? I'm particularly thinking of green veg like peas, broad beans, green beans. Fresh peas are a seasonal rarity, so are broad beans and green beans in supermarkets are often rather tired after their long trip from Kenya.

Thanks to the many years of research in the field, we know now that what we eat can have a strong impact on our mental health. Not only can it protect us from developing Alzheimer's, but it's an act of self-care on its own. "Biology is all about harmony, about finding equilibrium and homeostasis," says Dr. Lisa, which is why her approach differs from food restrictions and focuses on minimizing intake of those foods that don't help us feel better. 

Adderall is composed of a mixture of amphetamine salts – chemical compounds that have numerous potentially positive effects, including increased concentration, awareness and alertness. Amphetamines work, in part, by causing the release of dopamine, a neurotransmitter associated with pleasurable activities like eating. However, an amphetamine-induced release of dopamine occurs automatically – no pleasurable activity needs to occur – but a come-down feeling will likely be experienced eventually, which is associated with feelings of lethargy and mental dullness. Due to this side effect, Adderall cannot be said to be a nootropic.[12]

-Caviar contains a unique blend of nutrients that are perfect for the brain, including omega-3 fats (a brain-must), choline (a B vitamin needed to make memories), vitamin B6 and B12 (needed to support the nervous system), minerals like iron and magnesium (needed for healthy blood and tissues) and a good amount of protein combined with potent antioxidants like vitamin A, vitamin C, and selenium. [Because] caviar [can be] expensive, fatty fish would be my recommended alternative, especially Alaskan salmon [and] mackerel, bluefish, sardines [and] anchovies [to get the] omega-3’s your brain needs.

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.
Spaced repetition at midnight: 3.68. (Graphing preceding and following days: ▅▄▆▆▁▅▆▃▆▄█ ▄ ▂▄▄▅) DNB starting 12:55 AM: 30/34/41. Transcribed Sawaragi 2005, then took a walk. DNB starting 6:45 AM: 45/44/33. Decided to take a nap and then take half the armodafinil on awakening, before breakfast. I wound up oversleeping until noon (4:28); since it was so late, I took only half the armodafinil sublingually. I spent the afternoon learning how to do value of information calculations, and then carefully working through 8 or 9 examples for my various pages, which I published on Lesswrong. That was a useful little project. DNB starting 12:09 AM: 30/38/48. (To graph the preceding day and this night: ▇▂█▆▅▃▃▇▇▇▁▂▄ ▅▅▁▁▃▆) Nights: 9:13; 7:24; 9:13; 8:20; 8:31.
When it comes to brain power, greens should be on your plate (and cover a lot of that plate) every meal. “Leafy greens are a great base. You swap out a lot of the empty carbohydrates you get from things like pastas or breads, and you can use some leafy greens,” says Psychiatrist Drew Ramsey, MD, author of The Happiness Diet and Eat Complete: The 21 Nutrients That Fuel Brainpower, Boost Weight Loss, and Transform Your Health. “Again, just lots of nutrient density.”
Apkarian and colleagues imaged the brains of 68 participants and gave them personality tests. The researchers then randomly assigned the participants to groups that either received no treatment, sugar pills or a pain-killing drug. Those given pills were not told if they received a placebo or an active drug. Participants took the treatment for two weeks, stopped for one week and then repeated this cycle.

(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.)

This is a small water plant native to India. Bacopa is an adaptogen – it helps your body adapt to stress. It also improves memory in healthy adults[12] and enhances attention and mood in people over 65. [13] Scientists still don’t fully understand how Bacopa works, but they do know it takes time to work; study participants didn’t feel its memory-enhancing effects until they’d been supplementing with it daily for 4 weeks, so if you try Bacopa, stick with it for a month before you give up on it.
Cost-wise, the gum itself (~$5) is an irrelevant sunk cost and the DNB something I ought to be doing anyway. If the results are negative (which I’ll define as d<0.2), I may well drop nicotine entirely since I have no reason to expect other forms (patches) or higher doses (2mg+) to create new benefits. This would save me an annual expense of ~$40 with a net present value of <820 ($); even if we count the time-value of the 20 minutes for the 5 DNB rounds over 48 days (0.2 \times 48 \times 7.25 = 70), it’s still a clear profit to run a convincing experiment.
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.”)
The final question is: since I was taking an overdose, how did I mess up? I thought I was making sure I got at least the right RDA of elemental magnesium by aiming for 800mg of elemental magnesium and carefully converting from raw powder weight. So I went back to the original references, and scrutinizing them closely, they really were talking about elemental magnesium and indicating I should be getting 400mg elemental a day, but I did notice something: I got the dose wrong for the Solgar pills, it wasn’t 800mg elemental, it was 800mg of citrate - I misread the label. So I went from taking ~130mg of elemental magnesium in the first period to ~800mg in the second; I don’t think it is an accident that the second period seems to have been much worse (between the plot and the time trend).

It all comes down to my personal investigation and exploration into how one can use a variety of compounds to enhance the mind, all while combining ancestral wisdom and herbs such as bacopa and gingko with modern science and tactics such as LSD and racetams. The fact is, I’ve taken a deep dive in the wonderful world of smart drugs, nootropics and psychedelics, and have had the opportunity to interview some of the brightest minds in this unique field of brain enhancement on my podcast. So in this article, I’ll spill the beans on it all, including how to navigate the oft-confusing world of smart drugs and nootropics, the best brain supplement stacks I’ve discovered and experimented with, how to procure and microdose psychedelics and much more.
The problems with our mental functions begin if the blood flow to the brain cells is disrupted regardless of the reasons. There are countless capillaries in the head, which supply the brain with essential nutrients and oxygen. If the blood doesn’t get to these capillaries, your optimal mental performance is compromised. Here’s a term worth remembering – hypoperfusion. If you’re suffering from hypoperfusion, then this means you are having problems with the blood flow to your brain. Here’s a quick overview of the factors that most commonly cause hypoperfusion:
These little chemicals prompt the immune system to kick in and fight back against the stress through inflammation, as though stress is an infection. While inflammation helps protect us against illnesses and repairs the body when you do something like cut yourself, chronic inflammation is a different animal. It’s been linked to autoimmune diseases like multiple sclerosis, anxiety, high blood pressure and more. (2)

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..

Our #5 pick is BriteSmart which has a long list of ingredients, which look good on the bottle, but when we actually visited each one, we were left wondering about why some of them had been included. We did like the fact that it contained Vinpocetine and Huperzine A. We felt that this was a good product, but missing some key ingredients such as a supportive vitamin blend.
