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.

1. Used in biochemical research. Preparation of biological medium. Used in biochemical and nutritional research, medicine has the body to promote the cell oxidation and reduction function, increase white blood cell and prevent pathogens such as development role. Mainly used for all kinds of hair loss syndrome. Also used for dysentery, typhoid, influenza and acute infectious disease, asthma, neuralgia, eczema, and various poisoning disease, etc., and maintain the function of protein configuration. They are also used as food additive agent.
2. Biochemical reagent, used for biological preparation of media. Is amino acid infusion and compound amino acid preparation of important component.
3. Be feed nutrition enhancer, be helpful for animal growth, increase the weight and liver and kidney function, improve the quality of fur.
4. Can make cosmetic additives, can promote wound healing and prevent skin allergy and treatment effect such as eczema.
