Supports overall immune defense and provides enhanced support for upper respiratory health‡

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. 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 (n-acetyl-l-cysteine) 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 showed support for respiratory health. 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.‡

    NAC can cause G.I. upset, abdominal pain, vomiting, constipation or diarrhea.

    NAC is contraindicated with nitroglycerin.

    Zinc can cause a metallic taste in some individuals.

    Zinc may be contraindicated with certain antibiotics.

    There have been reports of quercetin causing headache or tingling in extremities.

    Elderberry may be contraindicated for individuals on immunosuppressant medications.

    Preliminary evidence suggests that quercetin may inhibit the metabolism of medications through the cytochrome pathways in the liver.

    Consult your physician for more information.
