D-Phenylalanine 60 VegCap

Product Description

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.

  • Helps support healthy mood
  • Helps support endorphin metabolism
  • Help support neurotransmitter function

Suggested Usage: 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.
