Glutathione

Glutathione is a tripeptide of glutamate, cysteine and glycine that every cell produces, and it is often called the master antioxidant because of its central role in neutralizing reactive oxygen species and supporting phase II detoxification in the liver. Its levels fall with age and oxidative load. Interest in supplementing it spans skin brightness (through its effect on melanin pathways), recovery, and general cellular health. A practical note: oral glutathione is poorly absorbed, which is why compounded injectable and specialized preparations are used, and a provider helps match the route to the goal. Injectable forms require refrigeration. A licensed provider reviews your history, including asthma, which warrants caution; compounded by a US-licensed pharmacy.
