Function: DL-Methionine is one of the essential amino acids for the human body. Deficiency can cause liver and kidney disorders. It is especially important for protecting liver function. It can promote the growth of hair and nails, and has the effects of detoxification and enhancing muscle activity.
The taste of sea urchin is related to methionine and can be formulated as a flavoring agent.
It can be used for amino acid infusion and comprehensive amino acid preparation.
