PureDefense with NAC contains EpiCor® that is a fermentate of Saccharomyces cerevisiae containing various bioactive metabolites.

  1. Natural killer cells are part of the body’s innate, or first-line, immune response.
  2. They respond more quickly than the adaptive immune system comprised of B cells and T cells.
  3. Once activated, natural killer cell activity peaks in as quickly as several hours, providing rapid support and wide-range immune defense.
  4. These nutrient metabolites are produced in a specialized fermentation process and support immune cell production.
  5. 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.
  6. NAC (N-Acetyl-L-Cysteine) promotes endogenous glutathione production for antioxidant protection and provides lung defense mechanisms for healthy respiratory function.
  7. In a randomized double-blind trial involving mostly older individuals, NAC showed support for respiratory health.
  8. Quercetin and elderberry provide flavonoids that offer additional support for immune and respiratory function while vitamin C, vitamin D and zinc play important roles in immune cell activation.
