Jarrow Formulas N-A-C Sustain 600 Mg (100 Tablets)

Jarrow NAC SUSTAIN™ is in a bilayer Quick Release / Sustained Release format of N-ACETYL-L-CYSTEINE (NAC), a powerful antioxidant amino acid and a precursor to the critical antioxidant glutathione. Glutathione exerts a variety of protective effects, including detoxification and intracellular defense against oxidative stress. The advanced bilayer technology combines 1/3 Quick Release and 2/3 Sustained Release formats to both immediately raise and to maintain blood levels over a longer period of time. NAC SUSTAIN™ releases in the small intestine over a 4 hour period, compared to the 1.5 hour biological half-life of NAC in the bloodstream. NAC is the pre-acetylized form of the simple amino acid Cysteine. N-acetyl-L-cysteine is a powerful antioxidant and a premier antitoxin and immune support substance. Antioxidants neutralize free radicals, which are produced by normal metabolic activity. When free radicals are left unchecked they cause damage to cells and DNA and are considered by scientists to be a major factor in the aging process. N-acetyl-L-cysteine has been shown to provide protection against free radicals as well as a broad range of toxic hazards such as: acrolein (found in barbecue and cigarette smoke and auto exhaust), bromobenzene, paraquat (a toxic herbicide), overdoses of acetaminophen, and the side-effects of cyclophosphamide and adrimycin (anti-cancer drugs). The key to this protection may be the sulfur and sulfhydryl groups contained in N-Acetyl Cysteine and its derivative, glutathione. Both cysteine and methionine are precursors of glutathione, but N-acetyl-L-cysteine is better. L-cysteine loses approximately 85% of its sulfur group (which becomes the active part of glutathione) in the digestion process, while N-Acetyl-L-cysteine, a more stable compound, loses only 15%. This means that N-Acetyl-L-cysteine has almost six times more effective sulfur groups left after digestion. N-Acetyl-L-cysteine is also a better source of glutathione than taking glutathione itself, because less than half of supplemental glutathione gets out of the digestive system and into the body. This greater efficiency is important since cellular glutathione levels tend to drop 30% to 35% with age. Supplemental N-acetyl-L-cysteine may have an anti-aging effect by increasing glutathione levels in:

• Liver
• Lungs
• Kidneys
• Bone Marrow

NAC is currently the dietary supplement of choice for building up or conserving the body's stores of glutathione, cysteine, and other sulfhydryl antioxidant resources. NAC is well tolerated, is well absorbed, resists enzymatic breakdown, and has been proven to raise internal GSH and cysteine levels when taken orally.
