PureDefense w/NAC contains a combination of EpiCor®, n-acetyl-l-cysteine (NAC), vitamins, zinc and herbal extracts designed to promote overall immune defense and provide enhanced support for upper respiratory health. EpiCor® is a fermentate of Saccharomyces cerevisiae containing various bioactive metabolites produced in a specialized fermentation process. These nutrient metabolites enhance immune cell production, including natural killer (NK) cells, B cells and T cells. Natural killer cells are part of the body's innate, or first-line, immune response. They respond more quickly than the adaptive immune system comprised of B cells and T cells. Once activated, natural killer cell activity peaks in as quickly as several hours, providing rapid support and wide-range immune defense.*
Uses For PureDefense w/NAC
Immune Defense: In one cellular study, EpiCor® promoted natural killer cell activation, as well as that of B cells and T cells. In two randomized, double blind, placebo-controlled trials, EpiCor provided statistically significant support for upper respiratory tract health and overall immune health. A separate open label, in-house trial indicated a strong potential for EpiCor supplementation to enhance secretory IgA levels after 30 days. These various actions demonstrate the ability of EpiCor® to address both innate and adaptive immune responses. NAC promotes endogenous glutathione production for antioxidant protection and provides lung defense mechanisms for healthy respiratory function. In a randomized double blind trial involving mostly older individuals, NAC supported comfort, nasal function and respiratory health through the winter months. Vitamin C, vitamin D and zinc provide nutritional immune support, enhancing healthy immune cell proliferation, activation and function. Vitamin D receptors have been found on a number of immune cell types, and it is believed to play an important role in seasonal immune health. Vitamin C and the bioflavonoid quercetin also help boost immune defense by supporting healthy antioxidant enzyme function.*
