DL Phenylalanine
DL-Phenylalanine is aracemic mixture of phenylalanine, an aromatic amino acid with antide pressant, 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. This agent also playsa 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).
