Glutathione Antioxidant Benefits of Glutathione? Glutathione is a sulfur-based molecule that is made up of three amino acids, cysteine, glycine, and glutamic acid, which plays a crucial role in the liver’s detoxification pathways. Unsurprisingly, glutathione is most concentrated in the liver, as well as in the heart and muscles, but is also present in every cell inside the body. Humans can synthesize glutathione, but not always in sufficient amounts, and our production also decreases as we age. https://www.nationalnutrition.ca/antioxidants/single-antioxidants/glutathione.html #Glutathione
