DL-Phenylalanine is a a-amino acid. The biological functions of D-amino acids remain unclear although some, such as DL-phenylalanine shows some pharmacological activity. It is sold as a nutritional supplement because of its analgesic and antidepressant activities. This analgesic activity can be explained by the possible blockage by D-phenylalanine of enkephalin and degradation by the enzyme carboxypeptidase A , and the mechanism of antidepressant activity may be accounted for by the precursor role of L-phenylalanine in the synthesis of the neurotransmitters, norepinephrine and dopamine. High levels of norepinephrine and dopamine are believed to have an anti-depressant effect.

DL-Phenylalanine works with body’s natural ability to ease pain. It assists in increasing the lifespan of brain chemicals that relieves pain. It is particularly effective in reducing pain caused by arthritis and aching muscles. DL-phenylalanine can treat persistent pain by stimulating nerve pathways in the brain responsible for controlling pain. Its effect increases if used with prescribed pain killers. DL-Phenylalanine, which is a combination of essential amino acid L-phenylalanine and D-phenylalanine, blocks an enzyme in the nervous system that enhances pain signals. This disturbance of pain signals causes the body’s healing mechanisms to start working faster. Use of DL-phenylalanine is also reported to have helped people in improving their mood and in treating depression. This is because a higher proportion of production of brain chemicals dopamine and norepinephrine, if went out of balance, cause depression, stress and frustration. Increasing the levels of these chemicals has an anti-depressant impact in the body.
