Glutathione is the premiere naturally occurring detoxifying molecule. You can increase your glutathione by taking N-acetyl cysteine (NAC) or your can take glutathione orally but most oral glutathione does not absorb well. Taking glutathione via the IV route is tremendously beneficial but next best route is taking oral glutathione in the acetylated form: acetyl glutathione. If you acetylate it, chemically speaking, then the acetyl glutathione is a very powerful detoxifier.
Acetyl-Glutathione is a novel oral acetyl-glutathione formulation that is stable in the stomach and gastrointestinal tract, well absorbed, and able to enter the cells directly and present to the cytosol for mitochondrial entry.* Acetyl-Glutathione uses pure Emothion® glutathione as the starting material.**
