Data coverage and detailed study classifications

Paper counts are separated by research topic below. One paper may contribute to multiple findings.

Analysis status: Public-ready

Ingredient analysis date:

How the grade was determined: C

The 16.3 evidence score includes 0 independent human studies and 0 clinical studies in the representative benefit area. The C tier remains conservative because of limited repetition across independent human clinical studies, too few clinical findings with an explicit effect direction.

The grade is based mainly on the research area with the most evidence. It does not mean the same result was found in other areas.
