  • Phenylalanine



Phenylalanine is one such essential amino acid. It is closely related to another amino acid, tyrosine, which just has an additional hydroxyl (OH) group. Liver cells contain an enzyme called phenylalanine hydroxylase, which can add this group and convert phenylalanine to tyrosine. Thus as long as this enzyme is functional and there is a reasonable supply of phenylalanine, tyrosine can be synthesized in your body and does not have to be included in the food that you eat.DL-Phenylalanine is a mixture of both the D and L forms of the amino acid phenylalanine.

DLPA may have the unique ability to block the enzyme enkephalinase in the central nervous system, thereby sparing feel good hormones such as endorphins and enkephalins. This formulation provides Free Form DLPA to promote optimal absorption and assimilation.
