Glutathione is a small peptide molecule composed of three amino acids: glutamic acid, cysteine, and glycine. It is synthesized by every cell of the body for the proper detoxification of metabolic waste products and is essential for healthy immune system function.* Glutathione also plays a critical role in the body’s defense system against oxidative stress by acting directly to neutralize free radicals, as well as by maintaining the activity of vitamins C and E.* This product has Glutathione in its reduced, active form for optimum bioavailability and includes Milk Thistle Extract and Alpha-Lipoic Acid as complementary ingredients.* Our Glutathione is a high quality material manufactured to rigorous standards.
