Description
Zinc Bisglycinate — zinc chelated to glycine for superior absorption and minimal gastrointestinal side effects.
Zinc is an essential trace mineral involved in over 300 enzymatic reactions in the body. The form matters enormously. Zinc oxide — the form used in most mass-market supplements — achieves approximately 50% of the absorption of chelated zinc forms. Zinc bisglycinate and zinc picolinate consistently outperform oxide in absorption studies.*
Zinc’s primary roles: immune function (required for T-cell development and neutrophil activity), testosterone and hormone synthesis (zinc-dependent enzyme aromatase regulation), wound repair-pathway research (collagen cross-linking and skin barrier function), protein synthesis (zinc finger proteins regulate gene expression), and antioxidant defense (cofactor for superoxide dismutase).*
Zinc deficiency is more common than recognized — particularly in vegetarians, older adults, and individuals with digestive conditions that impair mineral absorption.*
