Cysteine amino acid information page

Cysteine is a sulfur containing non-essential amino acid and is closely related to cystine, as cystine consists of two cysteine molecules joined together. It is an unstable nutrient and easily converts to cystine, but this does not cause a problem, since both can convert into the other – as required by the body.

Cysteine required for

Your skin, as well as detoxification of your body, requires cysteine. It is found in beta-keratin, the main protein in nails, skin as well as hair. It not only is important in collagen production but also assists in skin elasticity and texture.

supplement for skin, hair and nails

Cysteine is also required in the manufacture of the amino acid taurine and is a component of the antioxidant gluthione. It is useful to detoxify the body from harmful toxins and help protect the brain and liver from damage from alcohol, drugs etc.

It has also been found that it may help in strengthening the protective lining of the stomach as well as intestines, which may help prevent damage caused by aspirin and similar drugs.

Cysteine is also critical to the metabolism of a number of essential biochemicals including coenzyme A, heparin, biotin, lipoid acid, and glutathione.

Deficiency of cysteine

No direct deficiencies have been reported as such.

Dosage

The dosage listed is the Recommended Daily Allowance (RDA), but be aware that this dosage is the minimum that you require per day, to ward off serious deficiency of this particular nutrient. In the therapeutic use of this nutrient, the dosage is usually increased considerably, but the toxicity level must be kept in mind.

General dosage is not known but as supplement cysteine is used at 200 mg two to three times per day.

Toxicity and symptoms of high intake

None known, but damage to nerve cells in rats has been reported in very high dosage, and research data is still being waited upon.

People suffering from diabetes and Cystinuria should be careful of cysteine supplements.

Best used with

Best taken with selenium, vitamin B6 and vitamin E.

When more may be required

People suffering from AIDS/HIV may benefit from cysteine in proper amounts, as low levels are normally reported in people with this problem.

Food sources of cysteine

The body can synthesize cysteine from the amino acid methionine but is also found in high protein foods such as poultry, wheat, broccoli, eggs as well as garlic, onions and red peppers.
