Pure Encapsulations PureDefence with NAC - Immune & Upper Respiratory Support, 120 Capsules

Key Benefits for Immune and Respiratory Health

PureDefence with NAC offers comprehensive support for your body's natural defences. NAC acts as a precursor to glutathione, a master antioxidant that helps neutralise free radicals and supports lung defence mechanisms. Vitamin C and zinc are essential for immune cell activation, while vitamin D helps regulate immune responses. Quercetin and elderberry provide bioflavonoids that further support immune activity and help maintain healthy respiratory function. EpiCor® fermentate has been studied for its ability to enhance natural killer cell activity and support adaptive immune responses. Together, these ingredients work synergistically to maintain a robust immune system and support upper respiratory health.*
