L-phenylalanine: Information

L-phenylalanine is an essential amino acid. The body cannot synthesize independently, so the amino acid must be obtained from foods containing animal or plant source proteins.

Health Benefits of L-Phenylalanine

L-phenylalanine helps the body build proteins and manufacture the amino acid L-tyrosine, among other important substances. Tyrosine is an important precursor in the production of the neurotransmitters norepinephrine and dopamine, low levels of which are linked to depression.

Using Phenylalanine

Use as directed.

Side-effects and Cautions:

May exacerbate symptoms of tardive dyskinesia in some schizophrenics. May cause hypertension when used in conjunction with MAO inhibitor antidepressants. Pregnant/nursing women, individuals with tardive dyskinesia, schizophrenia, or hypertension should not use L-phenylalanine.
