Glutathione
Glutathione (GSH) is a tripeptide composed of glutamic acid, cysteine, and glycine. As a small-molecule peptide, it works synergistically with vitamins C and E and is widely used in beauty and skincare formulations.
According to the Taiwan Food and Drug Administration (TFDA), the daily intake limit for glutathione derived from torula yeast fermentation is 250mg. Products containing this compound must display the warning wording: “Individuals allergic to glutathione, pregnant women, breastfeeding women, and infants and young children should avoid consumption.”
