Source Naturals L-Phenylalanine Powder - A Free Form Essential Amino Acid - 100 Grams

L-Phenylalanine, an essential amino acid, is a precursor of the amino acid tyrosine and a whole series of neurotransmitters and hormones. Phenylalanine is first converted to tyrosine, which becomes L-dopa, which converts to norepinephrine, a key neurotransmitter and an adrenal hormone. L-Phenylalanine is also a direct precursor of PEA (phenylethylamine), another important neurotransmitter. The suggested use is 1/4 teaspoon daily with juice or water between meals, preferably in the morning. Please contact our in-house customer support if you have any questions.
