Ingredient amounts are hidden inside a blend

A blend total may be legal, but it prevents you from knowing whether any individual ingredient reaches a meaningful amount.

Evidence and sources

The panel lists “Resveratrol Elite™™ Proprietary Blend providing 18% trans-re” as a combined amount. A blend total can’t tell you whether any single ingredient reaches a dose used in research.
