D-Phenylalanine by Doctor's Best

D-phenylalanine is an essential 'non-protein' amino acid responsible for various bodily biochemical processes. The amino acid is the precursor of the brain neurotransmitters dopamine, adrenaline and norepinephrine. Phenylalanine can be considered a nootropic.

Phenylalanine explained

Phenylalanine comes in two different forms. The natural form occurs in food and is more specifically called L-phenylalanine. D-phenylalanine is the synthetic form that comes very close to the natural form. Most amino acids come in two enantiomers (mirror image molecules): in an L- (laevo = left) and in a D-structure (dextro = right). Both forms have unique properties and different effects in the body.

  • Necessary for various bodily processes
