Formulation Notes

Zinc Defense is a well-studied solution containing clinically-backed ingredients specifically formulated to support innate and adaptive immunity. L-OptiZinc, a mineral-amino acid chelate, boasts over 120% the absorption and retention of other forms of Zinc. TRAACS Copper Bisglycinate Chelate is smartly paired with Zinc to create a powerful antioxidant enzyme for defense against oxidative stress while maintaining the body's delicate Zinc-Copper balance. Quercefit (Phytosomal Quercetin) is proven to enhance quercetin bioavailability by up to 20x and performs the role of an ionophore; transporting Zinc across the membrane and into the cell where it is required most.

Formulated to exclude: Fillers, gluten, wheat, soy, corn, yeast, animal or dairy products, shellfish, fish, peanuts, tree nuts, egg, ingredients derived from genetically modified organisms (GMO's), artificial preservatives, sweeteners or colors.
