LifeSource Vitamins Zinc L-OptiZinc® with Copper — 30 mg, 100 Veg Capsules — Optimized Absorption & Immune Support*
LifeSource Vitamins OptiZinc® with Copper provides the most bioavailable form of zinc supplementation through patented zinc monomethionine technology, combined with balanced copper to prevent mineral imbalances and optimize absorption.* OptiZinc® combines zinc with methionine, an amino acid that enhances absorption and retention in the body, making it highly bioavailable and more stable at maintaining zinc levels over longer periods.* This advanced formula includes copper to maintain the proper zinc-to-copper ratio, as high levels of zinc can inhibit copper absorption, potentially leading to deficiency.* This balanced approach ensures comprehensive mineral support for immune function, antioxidant defense, and overall cellular health.* Produced in FDA-registered, GMP-certified facilities and 3rd-party lab tested for purity, potency, and label accuracy.
