Nootropic drinks and pills

Big promises, little testing.

TruBrain calls its drink “Nature’s Adderall” and BrainZen promises sharper focus today and a healthier brain tomorrow. Short answer: TruBrain’s own site says its formula contains noopept; we found rat studies of noopept but no placebo-controlled trial for thinking in healthy people, and under its drug name it is not approved for human use in the US. We found no study of either product.

We found no study of TruBrain. Its own site says its formula contains noopept, along with magnesium, tyrosine, carnitine and citicoline, and some drinks add caffeine with L-theanine (graded on /amanita-focus-tonic). Nothing here is comparable to Adderall, a prescription stimulant.
