Master antioxidant for detox and skin health

What is Glutathione

Glutathione (GSH) is a tripeptide composed of glutamate, cysteine, and glycine, considered the master intracellular antioxidant and a central cofactor in hepatic detoxification reactions (phase II). It neutralizes reactive oxygen species, regenerates other antioxidants (vitamins C and E), and conjugates toxins and heavy metals for excretion. Clinical studies investigate supplementation and IV administration for oxidative stress, hepatic function, and skin lightening, with tyrosinase inhibition being the basis of its dermatological effects.

Estou satisfeito até agora. Recomendo ler as contraindicações antes, como o site orienta.
