Verified by IngredientMDThe panel on the left is the one we evaluated, line by line.
All 2 actives checked against the clinical evidence: dose, form, and what the research actually shows.
Doses, ratios, and how the ingredients work together. That assessment is the verdict above: "Backed by human trials".
The verdict is public and identical whether or not a brand pays. A formula that does not clear the bar gets nothing.
Read by the engine against 2.1 million data points from clinical trials, PubMed and more than a hundred vetted sources. No individual reviewer is named or implied.
