"Phenylalanine is an essential amino acid that is necessary for the normal functioning of the central nervous system.
DL-phenylalanine (DLPA) is a 50/50 mixture of the synthetic D- form made in a laboratory and the L- natural form of this amino acid found in proteins. Phenylalanine is one of the few amino acids that can be utilized in its D- form.
Because DL-phenylalanine (DLPA) contains 50% L-phenylalanine and 50% D-phenylalanine, it possesses some of the effects of both forms.
DL-phenylalanine is a dietary supplement that aids in pain management and proper mood balance.
Phenylalanine plays a role in mood, appetite and mental alertness. It functions and acts as a building block for numerous proteins that are produced in the body.
The pain relieving effects of D-phenylalanine are believed to occur from its enhancing levels of endorphins and enkephalins, the body's naturally occurring opiates.
Phenylalanine occurs as a constituent of many proteins and is normally converted to tyrosine in the body.
