Zinc is one of the most abundant minerals in the human body, and with good reason, as it plays a critical role in over 300 enzymatic reactions, including the development and function of immune cells. In fact, several studies have shown that zinc supplementation may reduce the length of the common cold by up to 33%, and it can also significantly reduce the risk of infections and promote an immune response in older adults. Additional benefits of zinc include skin health, metabolism function, DNA synthesis, and protein production. HTN combines zinc with vitamin c in its non-GMO, natural flavored lozenge to further improve immune health and boost skin benefits.
