Glutathione is a small peptide molecule produced naturally by every cell in the human body. It is composed of three amino acids: cysteine, glutamic acid, and glycine. The liver contains particularly high concentrations of glutathione, where it plays a central role in cellular processes. Glutathione exists in two forms: reduced (GSH) and oxidised (GSSG). The reduced form — used in this NOW product — is the biologically active form and functions as an antioxidant compound in the body. Why Milk Thistle and Alpha Lipoic Acid? Milk thistle extract (100mg, standardised to 80mg silymarin flavonoids) is a botanical ingredient with a long history of use as a dietary supplement. Silymarin is the active compound group extracted from the seeds and fruit of Silybum marianum. Alpha lipoic acid (50mg) is a naturally occurring antioxidant compound found in every cell of the body. It is involved in energy metabolism. Both ingredients are included as complementary antioxidant compounds alongside the primary glutathione dose.
