N-Acetyl-L-Cysteine (NAC) is a biologically active precursor for glutathione (GSH), a potent multifunctional anti-oxidant cell protecting nutrient. NAC works via the replenishment of GSH and is perhaps medically best known given for acute liver poisoning with acetaminophen (Tylenol) drugs. According to Stanford University’s Dr. Kondala Atkuri, “NAC has been used successfully ... in a wide range of infections, genetic defects and metabolic disorders, including HIV infection and COPD. Over two-thirds of 46 placebo-controlled clinical trials with oral NAC have indicated beneficial effects.” The most well documented benefits are in flu prevention and treatment, and it may be helpful in COPD, diabetes, and cancer prevention (but NOT cancer treatment).
WARNING: although NAC and GSH may prevent cancer initiation as strong anti-oxidants and cytoprotectants. Patients should supplement NAC or GSH with caution if cancer has already developed, as GSH can also protect and prevent cancers from chemo and radiation therapy and generally enhance their survival.Dose: 500mg taken three times a day. One bottle provides 90 capsules.
