WHAT IS IT?

DL-Phenylalanine is the combined left and right isomers of the essential amino acid, phenylalanine. Each capsule contains 500 mg of dl-Phenylalanine (free form,) and Vitamin C (Ascorbyl palmitate) 10 mg. Other ingredient is vegetable capsule.

WHAT DOES IT DO?

Phenylalanine is an amino acid, a component of proteins which is also used by the body to build neurotransmitters, chemicals which conduct electrical impulses in the brain and nervous system. L-phenylalanine, the left handed molecule, is converted to L-tyrosine, then L-dopa, then norepinephrine, the brain's primary upper or feel-good neurotransmitter. D-Phenylalanine, the right handed version is converted primarily to phenylethylamine, made famous as the "feeling in love" chemical found in chocolate (though in very small quantities there.)
