Zinc is an essential trace mineral that supports many normal bodily processes and enzyme functions. This form, OptiZinc, is a bioavailable zinc monomethionine that helps contribute to hormonal balance and immune function.

This formula combines zinc with other minerals and vitamins to support normal muscle function and recovery through a nutrient-dense profile. The primary ingredient works alongside magnesium and vitamin B6 to support overall nutrient interactions that influence energy and performance.

What Does Zinc Do?

Zinc helps maintain normal hormonal balance and supports immune system function, contributing to daily wellbeing and recovery after activity. It plays a role in protein synthesis and energy metabolism, aligning with EFSA guidance on normal physiological functions.

Dr. Brilla of the University of Florida found that zinc, magnesium and vitamin B6 act together to promote hormonal balance, muscle relaxation and restorative sleep, supporting recovery in active individuals.
