N-Acetyl-L-Cysteine
600 mg 60 vegetarian capsules
Item Catalog Number:
01534

L-cysteine is a conditionally essential amino acid, one of only three sulfur-containing amino acids, the others being taurine (which can be produced from L-cysteine) and L-methionine (from which L-cysteine can be produced in the body by a multi-step process). Cysteine plays a role in the sulfation cycle, acting as a sulfur donor in phase II detoxification and as a methyl donor in the conversion of homocysteine to methionine.136-138 Cysteine also helps synthesize glutathione, the body’s most important intracellular antioxidant and a vital detoxifier.139-142

N-acetyl-L-cysteine (NAC) is the acetylated form of L-cysteine that has been used to break up pulmonary and bronchial mucous.143-146 It is very efficiently absorbed and has been shown to protect cells directly and support the immune system.146-155 NAC is an antioxidant and a free radical-scavenging agent that increases intracellular glutathione at the cellular level. NAC can act as a precursor for glutathione synthesis as well as a stimulator of the cytosolic enzymes involved in glutathione regeneration.146 NAC has been shown to protect against oxidative stress-induced neuronal death in cultured granule neurons.156

    Comments about Life Extension N-Acetyl-L-Cysteine, 600 mg 60 vegetarian capsules:

    Many medications leave extra elements. If you are on medication and have breakouts or scabby areas on your skin, it is likely the "garbage" that is left behind in your cells. Take one NAC and one of the same mg of vitamin C. There is not a better anti-toxin.
    PS: If you are taking statins, don't forget your CoQ10 for your heart and other muscles.
