The evidence
We tell you how good the research is. Even when it is thin.
Some supplements are backed by hundreds of trials. Others are popular but barely studied. Every benefit on this site carries one of three grades and a link to the studies behind it.

Many human trials agree, at the amount in this product.
- Moderate evidence
Human trials mostly agree, but they are small, short or mixed.
- Early evidence
A few small human studies or lab work. Promising, not proven.
