The Active Ingredient Is: Zinc (Bisglycinate Form)

Zinc is an essential mineral involved in several normal biological processes including hormonal health and enzymatic activity.

This formula uses zinc in a bisglycinate form for superior bioavailability, a common approach for minerals to support consistent absorption.

What Does Zinc Do?

Zinc participates in the maintenance of normal testosterone levels in the blood and supports normal hormonal activity, in line with EFSA guidance.

Dr. Prasad of the University of Nebraska found that zinc helps maintain normal testosterone levels in the blood, contributing to overall vitality and energy balance. This supports normal muscular and metabolic function in adults.
