DL-Methionine Introduction:

H&Z® DL-Methionine is one of the physical forms of methionine. DL-Methionine is not the natural form of methionine.Methionine is one of essential amino acids constituting the human body, involved in protein synthesis. Because it can not be generated in the body itself, it must be obtained from outside.
