DL-Phenylalanine, or DLPA, is a 50/50 mixture of the D- and L- forms of the amino acid phenylalanine (phenylalanine is one of the few aminos that can be utilized in its D- form). These are proteins that bind to opioid receptor sites in the brain, thereby influencing the perception of minor discomfort associated with normal physiological processes.
