Product insights

  • PureDefense w/NAC combines several ingredients to support both innate and adaptive immune responses.
  • EpiCor is a fermentate of Saccharomyces cerevisiae that enhances immune cell production, including natural killer cells, B cells, and T cells, while also supporting secretory IgA levels.
  • NAC (n-acetyl-l-cysteine) promotes glutathione production for antioxidant protection and supports healthy respiratory function.
  • Quercetin and elderberry provide flavonoids for additional immune and respiratory support, while vitamin C, vitamin D, and zinc play crucial roles in immune cell activation.
