Made with USDA Organic ingredients, our TheraZinc Lozenges help you during times of seasonal immune challenge. Quantum's drop lozenge is uniquely designed to eliminate the zinc coating taste accompanying most traditional zinc lozenges. This simple and tasty formula provides 7mg of zinc in a targeted, bioavailable form. Zinc gluconate is the chelated form that has been used in multiple immune health studies. Their lozenge delivery releases the zinc ions in your throat and mouth for effective immune support. Other forms of zinc may not convey consistent effects.
