real science.
Every ingredient rated against peer-reviewed studies. No influencer claims. No brand bias. Just the evidence.
How we rate evidence
8–10
Strong evidence
Multiple high-quality RCTs or meta-analyses with consistent, replicated findings and meaningful effect sizes.
4–7
Mixed evidence
Some positive findings exist but results are inconsistent, effect sizes vary, or study quality is limited.
0–3
Weak evidence
Little to no quality human trial data. Claims often rely on animal studies, industry funding, or theoretical mechanisms.
Every rating is assigned by our neuroscientist based on the quality, quantity, and consistency of available peer-reviewed research.
