DL-Phenylalanine

Overview:
DLPA is a mixture of two forms of the essential amino acid phenylalanine, the naturally occurring L-phenylalanine and the synthetic D-phenylalanine with nootropic effects. DLPA enhances mood and can increases alertness and improve memory and learning.

Scientific Name:
DL-Phenylalanine

Mechanisms:

  • DL-Phenylalanine crosses the blood-brain barrier easily
  • Increases the production of dopamine and noradrenalin – mood enhancer
  • Decreases chronic pain by blocking the action of enkephalinase[1]
  • Binds to Glutamate AMPA receptors improving synaptic communication –memory and learning enhancement[2]
