This is the D-Phenylalanine form, not DL, or L form.
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 brake down endorphins, the supplement can help support a healthy mood and normal functioning of the nervous system.
Adult use: Take 1 capsule daily on an empty stomach at least 20 minutes before meals, or as recommended by a nutritionally-informed physician. To ensure optimal phenylalanine absorption, avoid taking other amino acid supplements within 2-3 hours of intake.
Hypromellose (vegetarian capsule), microcrystalline cellulose, magnesium stearate (vegetable source).
Phenylalanine supplements should not be taken by children, pregnant, nursing, individual with phenylketonuria (PKU), high blood pressure, taking anti-psychotic medications or MAO inhibitors. Consult your physician before use.
Store in a cool dry place.
