Procysteine is a stable prodrug of cysteine, used to boost the body’s glutathione levels, acting as a powerful antioxidant to fight oxidative stress, particularly in skincare for anti-aging, and studied for conditions like alcoholic myopathy and HIV, though it’s mainly for research and not approved for human/veterinary use. It works by releasing cysteine inside cells, that is vital for glutathione synthesis, protecting against damage from free radicals, and supporting skin, hair, and overall cellular health. The directory classifies it as a discontinued API with a synthetic source/manufacturing origin. Other names for this substance include Oxothiazolidinecarboxylic acid and Koprosteine. Its PubChem CID is 72390.
