D-Phenylalanine 500 mg

Doctor's Best D-Phenylalanine is a non-protein amino acid that acts as an inhibiting agent to enzymes that degrade enkephalins, naturally occurring peptides in the body that metabolize endorphins. Endorphins are neurotransmitters that play a key role in the function of the nervous system and are associated with feelings of pleasure. By limiting production of enzymes that break down endorphins, the supplement can help support a healthy mood and normal functioning of the nervous system.
