4. L-Cystine aids in preventing the side effects of chemotherapy and radiation.

Cystine Application

1. For biochemical research.Preparation of biological medium.

Used in biochemical and nutritional research, it has the function of promoting cell oxidation and reduction, increasing white blood cells and preventing the development of pathogenic bacteria.Mainly used for alopecia.Also used for dysentery, typhoid fever, influenza and other acute infectious diseases, asthma, neuralgia, eczema and a variety of poisoning disorders, and maintain the role of protein configuration.Also used as a food flavoring agent.
