L-Phenylalanine (LPA) is a free-form amino acid that serves as a building block for various proteins that are produced in the body. It is converted to phenylethylamine, which functions as an anti-depressant and creates a positive, elevated mood. It improves memory and concentration. LPA also creates better fat mobilization and functions as an appetite suppressor.

L-phenylalanine has putative antidepressant activity.

L-phenylalanine is an essential amino acid which can be converted to L-tyrosine by a complex biochemical process which takes place in the liver. L-tyrosine can be converted by neurons in the brain to dopamine and nor epinephrine (noradrenalin), hormones which are depleted by stress, overwork and certain drugs. By replenishing nor-epinephrine in the brain, mental energy levels are enhanced and a feeling of contentment often occurs. Because of the liver conversion necessary for L-phenylalanine to have these effects, L-tyrosine is often faster acting. In addition, the conversion step from L-tyrosine to nor epinephrine may be enhanced if the cofactors (vitamins B6 and C)

L-phenylalanine may be taken in supplement form as a mild anti-depressant, to generally lift the mood and increase mental alertness. L-phenylalanine is able to have this effect by stimulating the production of certain excitatory neurotransmitters

L-Phenylalanine is a precursor to tyrosine, which converts to the neurotransmitters norepinephrine, epinephrine, dopamine, and tyramine. L-phenylalanine has a powerful effect on the nervous system and consequently effects mood and emotional well- being.
