Bacopa monnieri

Moderate

the memory herb that needs patience

Marketed
Evidence
Slightly overhyped

Marketing intensity 62 of 100. Evidence strength 52 of 100. Verdict: Slightly overhyped.

One of the better-supported nootropic herbs for memory - but it works slowly over weeks, not as an instant focus hit, and the gut side effects are real.

Marketed
Evidence
Slightly overhyped

Marketing intensity 68 of 100. Evidence strength 50 of 100. Verdict: Slightly overhyped.

Best-supported paired with caffeine for smoother focus. As a standalone anti-anxiety or sleep cure, the evidence is thinner than the nootropic marketing suggests.
