D-Phenylalanine, 500 mg, 60 Veggie Caps

Science-Based Nutrition™Helps Support Healthy MoodDietary SupplementVeganNon-GMO / Gluten Free / Soy FreeDoctor'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 brake down endorphins, the supplement can help support a healthy mood and normal functioning of the nervous system. Helps support healthy moodHelps support endorphin metabolismHelp support neurotransmitter function

DLPA, 750 mg, 60 Tablets

Dietary SupplementDL-PhenylalanineSupports an Alert StateDL-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 utilized in its D- form). Researchers believe that D-phenylalanine (DPA) inhibits the action of an enzyme that breaks down endorphins and enkephalins. These are proteins that bind to opioid receptor sites in the brain, thereby influencing the perception of discomfort. By obstructing the action of this enzyme, DPA may extend the life of endorphins and enkephalins and their positive influence on comfort levels. L-Phenylalanine is the precursor to two neurotransmitters that help support an alert state.
