As a vital and essential nutrient, Zinc is used in the body for numerous processes including DNA and protein synthesis, growth and development, and immune system function. Since the body cannot naturally make Zinc, many people rely on supplements to meet their daily required amount. We strive to offer the most advanced forms of zinc including lozenges, chelated zinc, and proprietary L-OptiZinc® so you can get the best, most highly bioavailable zinc possible.
