Formulation Notes

L-Phenylalanine, an essential amino acid, is a precursor of the amino acid tyrosine and a whole series of neurotransmitters and hormones. Because tyrosine is necessary for the synthesis of proteins and the production of the neurotransmitters dopamine and norepinephrine, L-Phenylalanine is also a direct precursor of PEA (phenylethylamine), another important neurotransmitter. Phenylalanine is an extremely important nutrient that must be obtained through the diet or by supplementation. Certain research publications indicate that L-Phenylalanine may help support the following: Supports nervous system Supports positive mood Supports an alert state
