What is DL-Phenylalanine?
Also known as DLPA, DL-Phenylalanine is a form of phenylalanine, an essential amino acid that the body requires but cannot generate on its own. DL-phenylalanine brings together two kinds of phenylalanine, D-phenylalanine and L-phenylalanine, for additional nutritional versatility. In the body, the L-phenylalanine part of DLPA can be converted to L-tyrosine, another crucial amino acid that plays key roles in the nervous and endocrine systems.**
The D-phenylalanine aspect of DLPA has been associated with promoting physical comfort. Research suggests that D-phenylalanine may block certain enzymes that break down endorphins and related peptides, which are compounds responsible for maintaining a state of comfort in the body. The L-phenylalanine component of DLPA benefits production of natural compounds called catecholamines, which includes dopamine, epinephrine and norepinephrine. These compounds act as both hormones and neurotransmitters, enabling DL-phenylalanine to support a positive, stable mood along with sharp cognition and mental clarity.**
L-phenylalanine is found in foods such as red meat, poultry, fish and dairy and soy products, while D-phenylalanine is synthetic. DLPA is the sole nutrient that features both forms and is only available as a supplement.**
DL-phenylalanine supplements feature natural L-phenylalanine and synthetic D-phenylalanine. DLPA supplements are offered as capsules and tablets. DL-phenylalanine supplements will sometimes supply the nutrient as free-form.
DLPA Directions for Use
Discuss DLPA supplements with your physician before adding DL-phenylalanine to your wellness program. Although no standard dosage has been set, DL-phenylalanine capsules and tablets are generally between 500 mg and 1,000 mg.
