DL-Phenylalanine(DL-Phenylalanine Note: free-form)
Ingredient research · DL-Phenylalanine
DL-Phenylalanine combines equal amounts of L-phenylalanine, an essential amino acid and precursor to dopamine and norepinephrine, with its D-form. It is taken mainly for mood and chronic pain, partly because D-phenylalanine may slow the breakdown of natural opioid peptides, but meaningful benefits of the mixture remain uncertain.
