How we tier evidence

Every claim gets the same rubric.

We don’t rate supplements — we rate claims about supplements. A single ingredient can earn Strong evidence for one benefit and Insufficient for another. The tier tells you how seriously to take a specific conclusion, not the molecule in general.

Strong
23 studies

At least two concordant RCTs with low-to-moderate risk of bias, or a high-certainty GRADE meta-analysis. This is where we feel confident saying yes.

Moderate
18 studies

One well-designed RCT plus replicated observational data. The signal is real; the effect size isn’t locked down.

Preliminary
174 studies

Early human data, mixed results, or a single trial. We report it, but we don’t bet the farm on it.

Insufficient

Animal-only studies, mechanism-only claims, or anecdote. We index these so you know they exist, not so you swallow them.
