Be added to animal feeds, L-methionine can help animals grow quickly in a short time and about 40% of their feed can be saved.

As an important component in protein synthesis, L-methionine has a protective effect on the heart muscle. At the same time, L-methionine can be converted into Taurine by sulfur, while Taurine has a very obvious hypotensive effect. L-methionine also has a good function for liver protection and detoxification, so it is commonly used in clinical treatment of liver diseases such as cirrhosis, fatty liver and various acute and chronic viral hepatitis.
