How Our Research Works

Unlike marketing-driven supplement sites, every grade here is calculated from real clinical data. We extract study results from PubMed papers — including sample sizes, study types, and effect directions — and run them through our grading algorithm. The result is a transparent, reproducible score you can trace back to the original research.
