Verifiable Science

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. EpiCor^® is a fermentate of Saccharomyces cerevisiae containing various bioactive metabolites. These nutrient metabolites are produced in a specialized fermentation process and enhance immune cell production. Research suggests that EpiCor^® enhances natural killer cell activation, B cell and T cell function, and secretory IgA levels.¹ In two randomized, double-blind, placebo-controlled trials, EpiCor^® provided statistically significant support for upper respiratory tract health and overall immune health.^2,3 A separate open label, in-house trial indicated a strong potential for EpiCor^® supplementation to enhance secretory IgA levels after 30 days. In another trial, EpiCor^® helped maintain a healthy immune response to environmental factors.⁴ Elderberry extract provides anthocyanins, flavonoids, and other polyphenols that support immune function. Studies have shown statistically significant immune support in both children and adults.^5,6 Preliminary research suggests quercetin helps to moderate the release of immune mediators, including cytokines and histamine.^7,8 Zinc and vitamin C help to promote immune defense by supporting immune cell proliferation, activation and function, as well as healthy antioxidant enzyme function.^9‡
