N-Acetyl Cysteine (“NAC”) is reported to increase Glutithione levels in the blood some 500 fold. Glutithione is perhaps one of the most powerful anti-oxidants in the body, with anti-oxidants being very important to muscular recovery and growth.
Anyone found it useful? Your thoughts?
NAC has been shown to beneficial in clinical research for aiding in protein accretion (muscle) in HIV+ individuals. NAC may increase intracellular glutathione in diseases which alter cellular antioxidant status. NAC is expensive and has not been thoroughly evaluated in healthy people.Two studies that I am aware of have shown whey protein isolate (the Immunotec brand and BiPro made by Davisco Foods) to increase intracellular glutathione (contains gamma-glutamyl-cysteine, a precursor to glutathione)and is cheaper and perhaps more effective than NAC.
