Cysteine is another one of the amino acids that are naturally occurring. It is not labeled as an essential amino acid, except for certain groups in the population, such as infants and the elderly. NAC cysteine – short for “N acetyl cysteine” – is the supplement form of cysteine and such available for sale on the Internet and in health food stores.

When checking the ‘Net, n-acetyl cysteine is sold as a cure for a wide variety of conditions. For example n acetyl cysteine and hangovers have been closely associated for a long time, since the premier cysteine chemical property rests on the fact that it helps the body with the process of detoxification. While a hangover is little more than the body’s response to an overdose of alcohol, cysteine is said to reduce these toxins quickly and effectively.

Furthermore, n acetyl cysteine and thyroid functions have been connected in that it is supposed to stimulate weight stabilization and weight loss. N-acetyl cysteine for gall bladder ailments and n acetyl cysteine for asthma sufferers have also been indicated. NAC cysteine for cancer prevention and treatment is indicated because cysteine is said to bind free radicals. To this end, cysteine colon cancer supplementation is supposed to help after surgery to prevent relapses. There have even been suggestions that n acetyl cysteine and cataracts may be beneficially connected.

Yet it is important to note that none of these cysteine related claims has been proven or approved by the FDA. In addition to the foregoing, due to the hydrophobicity of cysteine it is somewhat questionable what an over-supplementation of the substance will do to the body. While it is true that cysteine is found in human milk and hair, the question what does cysteine do when taken in supplementation form has not been satisfactorily answered. While the bold claims of the sites selling the substances have caused many to purchase the supplement, thus far the only benefits were found for those seeking to cure a hangover.

It is noteworthy that this amino acid is not just needed within the human body for its ability to detoxify the bodily system. In the animal kingdom, sheep in particular have been shown to depend on the substance to grow healthy wool that may later on be sheared. Failure to ingest enough of the substance via their diet has been linked directly to a complete stop in the wool production of the animals.
