Essential amino acid combo promotes healthy mood.
DL-phenylalanine contains the amino acids L-phenylalanine and D-phenylalanine.
L-phenylalanine, found naturally in protein-rich foods such as beef, poultry,
pork, milk, eggs and soy, is changed by the body into another amino acid,
L-tyrosine. L-tyrosine is responsible for the creation of definite proteins,
thyroid hormones, and brain chemicals including dopamine, epinephrine, and
norepinephrine. Low levels of these neurotransmitters have been associated with
poor mood and poor memory.
D-phenylalanine, not found naturally in any food source, inhibits metabolic
enzymes, such as Carboxypeptidase A, from preventing endorphin manufacture.
Endorphins are naturally-occurring opiate-like peptides that produce an
