Food & Cosmetic Grade S-Acetyl-L-Glutathione (SAG) Powder 98% CAS 3054-47-5 For Advanced Skin Brightening

Short Description:

S-Acetyl-L-Glutathione (SAG) is a bioavailable form of glutathione in which an acetyl group is attached to the sulfur atom of the cysteine residue. This structural modification significantly improves stability during digestion, allowing SAG to resist degradation in the gastrointestinal tract and be absorbed more efficiently compared to unmodified glutathione. Once inside cells, the acetyl group is cleaved by intracellular esterases, releasing active glutathione to support the body’s natural antioxidant defense system.
