DL-Phenylalanine (DLPA) from Source Naturals: Focus and
DL-Phenylalanine, or DLPA, is a 50/50 mixture of the D- and L-forms of the amino acid phenylalanine (phenylalanine is one of the few amino acids that can be used in its form D).
D-phenylalanine (DPA) inhibits the action of an enzyme that destroys endorphins and enkephalins. These are proteins that bind to opiate receptors in the brain, which influence the perception of discomfort associated with normal physiological processes. By interfering with the action of this enzyme, DPA can prolong the life of endorphins and enkephalins and their positive influence on the level of comfort. L-phenylalanine is the precursor to two neurotransmitters that help support an alert state.
DL-phenylalanine is therefore a natural support for the
