NAC (N-Acetyl Cysteine) is a more useful and more easily-aborbed form of the amino acid L-cysteine. This amino acid doubles as a potent antioxidant to help guard cells from oxidative damage. Many experts believe that it helps to protect the liver through boosting the levels of glutathione in the body.

NAC also helps to detoxify the body from arsenic, lead and mercury. Many believe that it helps support the immune system and other studies indicate that it effectively breaks up unwanted mucus and may improve influenza symptoms.

Vitabase NAC offers 600 mg of N-Acetyl Cysteine with every vegetarian capsule. Also included are molybdenum and selenium, both of which functione synergistically with NAC to offer added antioxidant activity.

N-Acetyl Cysteine widely known is a simple pre-acetylized amino acid Cysteine. Its existence is naturally seen in food and it acts as a premier antioxidant, powerful antitoxin and a substance that supports immunity. It is precursor of Glutathione; a substance protects the human cells from oxidative stress. NAC is said to suppress the replication of Human Immunodeficiency virus in addition to the act of maintaining the intracellular levels of glutathione. NAC also is effective against cell damage that is likely to be caused by radiation therapy and chemotherapy. This antioxidant acts effectively against toxins like mercury, lead, acetametaphen and other such related drugs. In addition to being an anti toxin and antioxidant it also know to be a mucolytic which is quite effective against diseases like asthma, pneumonia, chronic bronchitis and cystic fibrosis.

In general antioxidants are known to neutralize free radicals that are manufactured by metabolic activity. When the production of any free radicals if left unchecked, cells are likely to be damaged along with the DNA. This contributes to the ageing process. NAC has the benefit of being a more stable form of L-Cysteine because of the possession of acetyl group. Though it has all the qualities of L-Cysteine, it is more soluble in water and is better in terms of bio-availability. NAC is famously known as anti-amalgam, its market name as it aids in eliminating mercury from human cells. It neither has a stimulating nor a sedating effect proving to be a safe substance with good tolerance in people who take it.

Vitro studies reveal that NAC helps in rising the GSH levels which are responsive to inflammatory cytokines (tumor necrosis factor alpha). High levels of TNF are effective in activating and increasing virus replication. Hence the presence of NAC in the cells is of prime importance in keeping a check on GSH levels.

It is claimed that mechanisms mediating free radicals have contributed in development of treating certain neurodegenerative diseases such as hereditary ataxias. This is not the only disease but even patients with amyotrophic lateral sclerosis, Alzheimer's, and multiple sclerosis have been benefited by the intake of NAC.

Hence the application of NAC in various fields of medicine has been proved undoubtedly. Its versatility in treating and preventing diseases of various types has made it an important substance whose dependability is becoming increasingly popular.
