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.^‡

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.^‡
