Phenylalanine

L phenylalanine is an amino acid that occurs naturally, as opposed to D Phenylalanine, which is artificially made. L phenylalanine is a neurotransmitter that is thought to have marked medical benefits. However, there are also some risks and considerations associated with this amino acid.

L phenylalanine is useful in the treatment of vitiligo. In this condition, L phenylalanine in a topical form is applied to the skin and used in conjunction with UVA radiation. L phenylalanine may also be effective as part of treatment plan for depression.*
