I won't say what everyone else traditionally considers nootropics, but I've used a lot of things that improve brain health and function as a response to brain health issues at various points -- Brain Evolve product line (developed locally in Vancouver by Matthew Bennet, under Bennet's Choice brand before being sold to "havn life") -- R-Alpha Lipoic Acid + ALCAR stack (works specially when you mix them; usually up to 2000 mg / day of ALCAR, building up to it over a few days) -- Bulletproof coffees -- Phosphotidyl Serine -- Alpha Brain by Onnit (a while back) -- Bulletproof company's Brain Octane MCT Oil (very superior to brain function compared to standard MCT) -- Turmeric -- Caffeine -- Theacrine as opposed to only caffeine (not to be confused with L-Theanine ------ I have no idea why searching for one gives results of the other, they're completely different things; and to be honest, L-theanine has never really helped me very much) -- Theobromine -- Green tea -- Methylene Blue -- pharmaceutical forms of dexadrine-based compounds (prescriptions for ADHD) ... "biohacks" such as ketogenic diet & carnivore diet herbals: -- adaptogenic herbs such as ashwagandha, holy basil, gotu kola -- pro-brain mushrooms such as lion's mane, turkey tail, reishi, cordyceps I can say that if you've never tried a lot of the more obscure things on that list most people haven't heard of... something is likely to give you an interesting experience _______ ... some people will argue that entheogens can also improve brain function, as well as cannabis but arguably, there is a LOT of nuance to this topic... persue at your own risk particularly with regard to the legal and health ramifications --- which is why I will not be endorsing them on the internet. Rather than say too much personally about this, I'll just pass it off to writers such as Tim Ferris who have discussed the topic in books such as Tools of Titans and various podcasts, and you can feel free to digest such opinions as claimed by men such as the allegedly existent "Jim Blerris".
