S-Acetyl Glutathione Synergy (SA-GSH) is a unique form of glutathione, one of the most powerful antioxidants naturally produced by the body. An acetyl group (COCH3) is attached to the sulfur atom of cysteine in the glutathione molecule. SA-GSH is well-suited for oral ingestion because this acetyl group protects glutathione from degradation in the gastrointestinal tract. Once absorbed and inside the cells, it is eliminated, leaving the glutathione molecule intact. SA-GSH helps support immune function and optimize glutathione-dependent liver detoxification pathways. It is the ideal choice when higher doses of glutathione are recommended. This product also contains N-acetyl-L-cysteine (NAC) and vitamin B6, both important for glutathione production.
