D-Phenylalanine is an essential amino acid found in dietary supplements. Phenylalanine is also found naturally in plants, bacteria and the milk of mammals. It has analgesic properties since it promotes the natural production of endorphins. Hence, D-phenylalanine supplements are often recommended for dogs that have been diagnosed with early stage dog arthritis.
