Elderberry Zinc Lozenge, with Vitamin C & Immune Blend, is a combination of herbal cofactors along with an essential mineral that plays a major role in antioxidant defenses and healthy immune function. Elderberry contains several compounds that help support healthy immune function. These active compounds have been researched for their benefit of defense against viruses. The mineral zinc is also a critical nutrient for the support of a healthy immune system. The optimal development of immune cells, particularly T-lymphocytes, depends upon normal zinc levels within the body. In regard to immune response, zinc deficiency has been shown to reduce the physical size of the thymus gland which is crucial to the maturation of T-lymphocytes. Our Elderberry Zinc Lozenge was developed to help support the body's natural defenses and overall wellbeing. Additionally, the Elderberry Zinc Lozenge contains other commonly recognized immune-supporting nutrients like Vitamin C and Echinacea.
