Cystine is a crystalline, sulfur-containing amino acid, formed from two molecules of the amino acid cysteine. It can be converted to cysteine by reduction and was discovered in 1810 but was not recognized as a component of proteins until 1899, when it was isolated from animal horn ?it is particularly abundant in skeletal and connective tissues, hair and digestive enzymes.

The steps followed in the formation of cystine and cysteine, is from methionine to cystathionine and then to cysteine to cystine. For more information please see cysteine as well.

Cystine is required for?
Required for proper vitamin B6 utilization and is also helpful in the healing of burns and wounds, breaking down mucus deposits in illnesses such as bronchitis as well as cystic fibrosis.

Cysteine also assists in the supply of insulin to the pancreas, which is needed for the assimilation of sugars and starches.

It increases the level of glutathione in the lungs, liver, kidneys and bone marrow, and this may have an anti-aging effect on the body by reducing age-spots etc.

It has been shown as a detoxification agent to protect the body against damage of alcohol and cigarette smoking, and may be effective in preventing hangovers, as well as preventing liver and brain damage.

Deficiency of cystine?
In chronic diseases it appears that the formation of cysteine from methionine is prevented, resulting in a deficiency.

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.

Toxicity and symptoms of high intake?
People suffering from diabetes should be careful when taking supplementation, as it could inactivate insulin.
