What is known

Each outcome with its grade (how strong the evidence is, A to D), the size of the effect where the entry records one, and how often studies agree.

Outcome	Grade	Effect size	Agreement
Bacopa MonnieriThe nootropic that actually improves memory — but slowly, over 8–12 weeks, not on the day you take it.	Evidence grade B	Unclear	mixed
Ginkgo BilobaA circulation-and-memory classic that failed the big dementia-prevention trials — modest, niche, and a bleeding risk.	Evidence grade C	Unclear	mixed
Citicoline (CDP-Choline)A choline source with modest attention and memory data — the more evidence-backed of the popular cholinergics.	Evidence grade C	Unclear	mixed
PhosphatidylserineA membrane phospholipid with old age-related-memory data and a cortisol-blunting angle for stressed athletes.	Evidence grade C	Unclear	mixed
Huperzine AA potent acetylcholinesterase inhibitor with some dementia data — effectively a drug, not a casual nootropic.	Evidence grade C	Unclear	mixed
SageA culinary herb with small but repeatable acute-memory-and-attention signals.	Evidence grade C	Unclear	mixed
VinpocetineA cerebral-blood-flow nootropic used as a drug abroad, unproven for healthy cognition and unsafe in pregnancy.	Evidence grade D	Unclear	mixed
PramiracetamA potent racetam with intriguing older memory data but thin, dated human evidence.	Evidence grade D	Unclear	mixed
