DL-Phenylalanine is a racemic mixture of phenylalanine, an aromatic amino acid with antidepressant, analgesic and appetite suppressant properties. The antidepressant effect of DL-phenylalanine may be accounted for by its precursor role in the synthesis of the neurotransmitters norepinephrine and dopamine. Elevated brain norepinephrine and dopamine levels are thought to be associated with antidepressant effects. This agent also plays a role in alleviating mood swings of premenstrual syndrome (PMS), increasing energy and mental alertness and heighten the ability to focus in individuals with attention deficit hyperactivity disorder (ADHD).
Amino acids are the building blocks of protein. L-phenylalanine is an essential amino acid. It is the only form of phenylalanine found in proteins. D-phenylalanine is not an essential amino acid, and its role in the body is not currently understood. DL-phenylalanine is made in a lab.
People use phenylalanine for a disorder that causes white patches to develop on the skin (vitiligo). It is also used for attention-deficit hyperactivity disorder (ADHD), chronic pain, aging skin, depression, and many other purposes, but there is no good scientific evidence to support most of these uses.
