PRODUCT FUNCTION                                                                  

Cystine assists in the formation of skin and is important for detoxification. By reducing the body's ability to absorb copper, cystine protects cells from copper poisoning. When it is metabolized, it will release sulfuric acid, and sulfuric acid will chemically interact with other substances to increase the detoxification function of the entire metabolic system. In addition, it assists in the supply of insulin, which is necessary for the body to utilize sugar and starch. It can also promote cell redox, make the liver function vigorous, promote the proliferation of white blood cells, and prevent the development of pathogenic bacteria.
