Cysteine, one of the 20 natural amino acids, is a non-essential amino acid containing sulfur (like methionine). Animals can be synthesized by methionine and serine. It can alleviate and repair radiation damage to human body. It also has a wide range of detoxification effects in human body, and is a therapeutic drug for acrylonitrile and aromatic acidosis. It helps to break away from alcohol addiction and is necessary for the brain and liver to function; it is necessary for the regeneration of liver cells.

Function
1. Cystine is a crystalline, sulfur-containing amino acid, formed from two molecules of the amino acid cysteine.
2. 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.
3. L- Cystine helps strengthen the immune system, reduce damage from free-radicals, repair RNA-DNA in the cells and assimilation of vitamin B6. L-Cystine is closely related to the amino acid, L-Cysteine.
4. L-Cystine aids in preventing the side effects of chemotherapy and radiation.
5. It increases L-Glutathione levels in the lungs, liver, kidney and bone marrow.
6. L-Cystine also has an anti-aging effect on the body which can reduce the accumulation of age spots.
Application
1. Medicine is to promote the body's cells on the oxidation and reduction function, increase the white blood cells and to prevent pathogenic bacteria growth, and so on. Mainly used for all kinds of alopecia. Also used in acute infectious diseases such as dysentery, typhoid fever, flu, asthma, neuralgia, eczema, as well as a variety of poisoning disease, etc., and maintain the function of protein conformation. Also used as a food flavoring
2. Be feed nutrition enhancer, be helpful for animal growth, increase the weight and liver and kidney function, improve the quality of fur.
3. Can make cosmetic additives, can promote wound healing and prevent skin allergy and treatment effect such as eczema
