Detailed Product Description
CBH-Cysteine is an important amino acid making up of proteins in the form of cystine. Cysteine also helps to detoxify harmful toxins, thereby protecting and preserving the cells. It is a powerful antioxidant, especially, combined with Vitamins C and B1. Cysteine is widely used in food and feed industry as an important additive.
