Pure encapsulations PureDefense w/NAC

Natural killer cells, critical white blood cells that science calls NK’s, are part of the body’s innate, or first-line, immune response. NK’s respond more quickly than your adaptive immune system’s 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.‡


We designed this travel supplement with a complex called EpiCor® since it may enhance immune cell production. We also included NAC for antioxidant protection and healthy respiratory function. Additional ingredients like quercetin and elderberry provide flavonoids for immune and respiratory function, while vitamin C, D and zinc play important roles in immune cell activation.‡
