Phenylalanine D - L

The amino acid Phenylalanine exists in two forms, the D- and L- forms. L-Phenylalanine(LPA, C9H12NO2) is a neutral amino acid found in proteins, coded for by DNA. Its mirror image, D-phenylalanine (DPA), can be synthesized artificially. L-phenylalanine is used in the human body, where it is an essential amino acid. L-Phenylalanine can also be converted into tyrosine. Tyrosine is converted into L-dopa, norepinephrine, and epinephrine. D-phenylalanine can only be converted into phenylethylamine. The genetic disorder phenylketonuria is an inability to metabolize phenylalanine. The synthesized mix DL-Phenylalanine (DLPA), which is a combination of the D- and L- forms, is used as a nutritional supplement.

Consult your physician before begining any dietary supplement regimen.

FEDERAL HEALTH ORGANIZATIONS

Food and Drug Administration (FDA)
FDA regulates dietary supplements under a different set of regulations than those covering "conventional" foods and drug products (prescription and Over-the-Counter). Under the Dietary Supplement Health and Education Act of 1994 (DSHEA), the dietary supplement manufacturer is responsible for ensuring that a dietary supplement is safe before it is marketed. FDA is responsible for taking action against any unsafe dietary supplement product after it reaches the market. Generally, manufacturers do not need to register with FDA nor get FDA approval before producing or selling dietary supplements. Manufacturers must make sure that product label information is truthful and not misleading.
