L-Methionine In the shape of white crystalline powder, DL-Methionine can be used as feed additive. As an essential amino acid, DL-Methionine is not synthesized in human, hence we must ingest DL-Methionine or DL-Methionine -containing proteins. As a food additive, DL-Methionine is an essential food ingredient in our food supply. Of our food additives and food ingredients, DL-Methionine has won a high reputation in China and foreign countries.
Functions of DL-Methionine:
DL-Methionine is one of the essential amino acids for human body, and is especially vital to the protection of liver function. The lack of DL-Methionine will cause the dysfunction of liver and kidney. It can accelerate the growth of hair and nail, with functions of detoxification and strengthening the muscle activity ability and so on. It is safe to use it in the food, but not appropriate for infants and young children's food.
