Life Choice DLPA DL-Phenylalanine - DL-Phenylalanine (DLPA) is an essential amino acid, meaning the body produces it naturally from the diet. All proteins in the body are made from amino acids, which is why amino acids are often referred to as the “building blocks” of proteins. DLPA is used as natural pain control by a variety of people, whether they are active or sedentary. It may help relieve pain from whiplash, rheumatoid arthritis, lower back pain, migraines, muscle cramps and soreness, as well as postoperative pain. Moreover, it has been shown to be effective for boosting emotional enthusiasm for life and fighting depression. DLPA is converted into the amino acid L-tyrosine in the body, through complex chemical reactions in the liver; L-tyrosine, in turn, can be converted into dopamine and norepinephrine. Through these conversions, DLPA may be able to help relieve stress and depression and help suppress appetite. Athletes use DLPA for many of its benefits: to improve focus for a workout, to help relieve post-exercise soreness, and to suppress appetite when needed.
