Uses
Phenylalanine is an amino acid commonly found as a component of total parenteral nutrition.
L-phenylalanine may be helpful in some with depression. It may also be useful in the treatment of vitiligo. There is some evidence that L-phenylalanine may exacerbate tardive dyskinesia in some schizophrenic patients and in some who have used neuroleptic drugs.
Phenylalanine is also used to associated treatment for these conditions: Amino acid supplementation
How Phenylalanine works
The supposed antidepressant effects of L-phenylalanine may be due to its role as a precursor in the synthesis of the neurotransmitters norepinephrine and dopamine. Elevated brain norepinephrine and dopamine levels are thought to be associated with antidepressant effects.
The mechanism of L-phenylalanine's possible antivitiligo activity is not well understood. It is thought that L-phenylalanine may stimulate the production of melanin in the affected skin
Toxicity
L-phenylalanine will exacerbate symptoms of phenylketonuria if used by phenylketonurics. L-phenylalanine was reported to exacerbate tardive dyskinesia when used by some with schizophrenia.
Elimination Route
Absorbed from the small intestine by a sodium dependent active transport process.
