Function and application:

L-Cysteine is a nonessential amino acid that assists in the synthesis of proteins. L-Cysteine HCl (hydrochloride) is Cysteine that is bound to Hydrochloride to assist in absorption.

L-Cysteine hydrochloride is soluble in water and can be quickly absorbed by human body when it is made into injection or tablet. It is the main raw material for the production of carboxymethyl cysteine and acetylcysteine;

Bread improver; nutritional supplement, antioxidant, color protection agent. It has the function of detoxification, prevention of radiation injury, treatment of tracheitis and phlegm.

L-Cysteine HCl is a nonessential amino acid that may help support digestion, lung health, and immune function.† It has natural anti-inflammatory properties and may aid in maintaining healthy glucose levels in already healthy individual when used in conjunction with a healthy diet & exercise. L-Cysteine HCl may also work to promote a calm mood and an overall feeling of well-being.
