NaturesPlus Immune Zinc Lozenges are a powerful, dual-action formula designed to provide targeted support for overall immune health and the upper respiratory tract. This formula delivers ionic zinc, sourced from zinc citrate, gluconate, and bisglycinate, along with copper, which is included to maintain essential mineral balance and help protect cells from oxidative stress. The lozenge format ensures that ionic zinc is delivered directly to the soft tissues of the mouth, throat, and sinus areas, while the systemically absorbed zinc supports healthy immune-barrier tissues and active defenses. The lozenges are also infused with antioxidant-rich fruits and feature a naturally delicious Berry flavor. This supplement is vegetarian, vegan, and gluten-free.
