What Is Glutathione Powder? Glutathione is a naturally occurring antioxidant made from three amino acids (cysteine, glycine, and glutamic acid). It helps protect cells from oxidative stress, supports detoxification, and plays roles in immune function. A glutathione powder supplement is a dietary form typically made from reduced L-glutathione, and can be mixed into water, juice, or smoothies. Some products also include other nutrients like Vitamin C, biotin, or collagen aimed at skin and overall wellness.
