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.

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. Used in biochemistry and nutrition research, and has the function of promoting cell oxidation and reduction of the body in pharm, increase the white blood cells and preventing the development of pathogenic bacteria and so on. Mainly used for all kinds of hair loss. It is also used in acute infectious diseases, such as dysentery, typhoid fever, influenza, asthma, neuralgia, eczema, and various kinds of toxic diseases, etc., and has the function of maintaining the structure of protein.
