What It Actually Is
BioPerine® is a standardized black pepper extract, concentrated for piperine, the compound responsible for black pepper's pungency and its studied effects on nutrient absorption.
What Research Generally Shows
Piperine has published research showing it can significantly increase the bioavailability of curcumin when taken together — addressing curcumin's well-known poor absorption on its own.
Why It's Dosed At 5mg
5mg is a standard BioPerine® dose used across many supplement formulas pairing it with curcumin, consistent with amounts used in the underlying absorption research.
