S-Acetyl L-Glutathione, a highly bioavailable form of the potent antioxidant glutathione, plays crucial roles in health and longevity. Natural production of glutathione reduces after age 45, making supplementation beneficial. It supports neuron health, immune system function, and promotes a healthy liver. Unlike most glutathione supplements that degrade rapidly after ingestion, S-Acetyl L-Glutathione’s unique acetyl function group allows it to remain intact in the gut, enabling better absorption and efficacy.
