About LifeOn NAC N-Acetyl Cysteine: N-Acetyl Cysteine (NAC) is the stable form of the amino acid L-Cysteine, and is an important and powerful antioxidant that studies suggest may aid the body in stabilizing the formation of protein structures that, in-turn, support cellular health. NAC has been shown in studies to act as a free-radical scavenger, inhibiting the production of “superoxides,” and promotes the replenishment of intracellular glutathione, a vital cellular antioxidant. LifeOn NAC with added Zinc is designed to help the body— including the respiratory tract, liver, and all other vital organs—by way of greater antioxidant protection, encouraging mucus relief, and glutathione production, helping organs better perform their functions. With a low molecular weight that is well absorbed -via- oral administration, LifeOn NAC is designed specifically to promote glutathione production. N-Acetyl Cysteine (NAC) Is A Semi-Essential Amino Acid: NAC is considered “semi-essential” because your body can produce it from other amino acids. NAC is the precursor to the antioxidant glutathione. Direct glutathione supplementation is ineffective because it cannot cross the blood-brain barrier. NAC readily crosses the blood-brain barrier, promoting the body’s own glutathione production. Promotes Detoxification Of Kidney And Liver: NAC plays an important role in the body's natural detoxification process. Studies have shown that antioxidants may help vital organs—such as the liver and kidneys—work more effectively at removing toxins from the body. NAC is often used in hospitals to treat toxic conditions , 2 such as acetaminophen overdose, or certain types of radiation exposure, helping to protect the liver and kidneys.
