Maca root has been used by indigenous people groups in South America for thousands of years. It’s part of the mustard family found primarily in Andean regions and some of its primary uses include improving sexual function, memory and learning as well as reducing the effects of osteoporosis. The standard effective dose ranges from 1,500 to 3,000 mg.
l-Theanine – A 2014 systematic review and meta-analysis found that concurrent caffeine and l-theanine use had synergistic psychoactive effects that promoted alertness, attention, and task switching;[29] these effects were most pronounced during the first hour post-dose.[29] However, the European Food Safety Authority reported that, when L-theanine is used by itself (i.e. without caffeine), there is insufficient information to determine if these effects exist.[34]
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.
Since coffee drinking may lead to a worsening of calcium balance in humans, we studied the serial changes of serum calcium, PTH, 1,25-dihydroxyvitamin D (1,25(OH)2D) vitamin D and calcium balance in young and adult rats after daily administration of caffeine for 4 weeks. In the young rats, there was an increase in urinary calcium and endogenous fecal calcium excretion after four days of caffeine administration that persisted for the duration of the experiment. Serum calcium decreased on the fourth day of caffeine administration and then returned to control levels. In contrast, the serum PTH and 1,25(OH)2D remained unchanged initially, but increased after 2 weeks of caffeine administration…In the adult rat group, an increase in the urinary calcium and endogenous fecal calcium excretion and serum levels of PTH was found after caffeine administration. However, the serum 1,25(OH)2D levels and intestinal absorption coefficient of calcium remained the same as in the adult control group.
Caveats aside, if you do want to try a nootropic, consider starting with something simple and pretty much risk-free, like aromatherapy with lemon essential oil or frankincense, which can help activate your brain, Barbour says. You could also sip on "golden milk," a sweet and anti-inflammatory beverage made with turmeric, or rosemary-infused water, she adds.
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)

I can test fish oil for mood, since the other claimed benefits like anti-schizophrenia are too hard to test. The medical student trial (Kiecolt-Glaser et al 2011) did not see changes until visit 3, after 3 weeks of supplementation. (Visit 1, 3 weeks, visit 2, supplementation started for 3 weeks, visit 3, supplementation continued 3 weeks, visit 4 etc.) There were no tests in between the test starting week 1 and starting week 3, so I can’t pin it down any further. This suggests randomizing in 2 or 3 week blocks. (For an explanation of blocking, see the footnote in the Zeo page.)
Back home, I contacted Aubrey Marcus, whose company Onnit Labs produces Alpha Brain. He attributed my lucid dreaming to increased levels of the neurotransmitter acetylcholine, which enhances REM dreaming. Alpha Brain has two ingredients that boost acetylcholine levels: GPC choline, which the body converts to acetylcholine, and Huperzine A, an alkaloid derived from Chinese club moss, also known as Huperzia serrata. "Huperzine A disarms the enzyme that naturally breaks down acetylcholine," Marcus said. "So while the GPC choline is being converted to acetylcholine, the Huperzine A is keeping it from disappearing. It's like plugging the drain and turning on the faucet."
When Giurgea coined the word nootropic (combining the Greek words for mind and bending) in the 1970s, he was focused on a drug he had synthesized called piracetam. Although it is approved in many countries, it isn’t categorized as a prescription drug in the United States. That means it can be purchased online, along with a number of newer formulations in the same drug family (including aniracetam, phenylpiracetam, and oxiracetam). Some studies have shown beneficial effects, including one in the 1990s that indicated possible improvement in the hippocampal membranes in Alzheimer’s patients. But long-term studies haven’t yet borne out the hype.
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.

We felt that True Focus offered a good product but the price was slightly high compared to others. Their website doesn’t show a clear money-back guarantee though, which definitely reduced their rating. We found that their customer reviews were mixed and saw that some consumers did not mind paying a little more for a product that is more consumer friendly.
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.
A constituent of the turmeric spice, curcumin was first discovered for its brain health benefits when epidemiological studies revealed those in regions with a high consumption of the curry spice turmeric had fewer reported cases of cognitive diseases. It is theorized that the unmatched anti-inflammatory power of curcumin, in combination with its unique antioxidant make-up, inhibits the formation of amyloid build up in the brain.
Finding a usable product on Amazon caused me some difficulties. I wanted a 500mg magnesium-citrate-only product at <$20 for 120 doses, but I discovered most of the selection for magnesium citrate had sub-500mg doses, involved calcium citrate or other substances like zinc (not necessarily a bad thing, but would confound an experiment), were mostly magnesium oxide rather than citrate, or some still other problem. Ultimately I settled on Solgar’s $13 120x400mg magnesium citrate as acceptable. (To compare with the bulkiness of the LEF vitamin D+l-threonate powder, the Office of Dietary Supplements says magnesium citrate is 16% magnesium, so to get 400mg of magnesium as claimed, would take 2.5g of material, rather than 7g for 200mg; even if l-threonate is absorbed 100% and citrate 50%, the citrate is ahead. The pills turn out to be wider and longer than my 00 pills; if I want to get them into my gel capsules, I have to crush them into fine powder. The powder from one pill turns out to take up 2 00 pills.)
Eugeroics (armodafinil and modafinil) – are classified as "wakefulness promoting" agents; modafinil increased alertness, particularly in sleep deprived individuals, and was noted to facilitate reasoning and problem solving in non-ADHD youth.[23] In a systematic review of small, preliminary studies where the effects of modafinil were examined, when simple psychometric assessments were considered, modafinil intake appeared to enhance executive function.[27] Modafinil does not produce improvements in mood or motivation in sleep deprived or non-sleep deprived individuals.[28]
