A patented black pepper extract included to support ingredient absorption.
Bioperine is a standardized black pepper (Piper nigrum) extract, best known for its piperine content and its studied role in enhancing nutrient absorption.
Rather than acting on energy or hormones directly, Bioperine's job in Primordial Vigor X is to help the body absorb the other seven ingredients more effectively.
It's a small-dose addition, common in multi-ingredient formulas that want their active botanicals to actually be absorbed rather than pass through unused.
