Overview

Thorne Zinc Bisglycinate provides 15mg of zinc from zinc bisglycinate — a chelated form where zinc is bound to two glycine molecules. This chelation dramatically improves absorption (up to 43% bioavailability vs 4% for zinc oxide) and virtually eliminates the nausea and stomach upset common with other zinc forms. The 15mg dose is conservative and well-suited for daily maintenance supplementation. Zinc is essential for immune function (required by over 300 enzymes), testosterone production, wound healing, and taste/smell perception.
