DL-Phenylalanine Background and Benefits

Phenylalanine is an amino acid generally abbreviated as F or Phe. C6H5CH2CH(NH2)COOH  is the chemical formula for the phenylalanine molecule. although their exact structure may vary. Phenylalanine occurs in two different forms called D-phenylalanine and L-phenylalanine. These forms are referred to as enantiomers of phenylalanine, which structurally mirror images of each other. The structures of phenylalanine were established in the late 19th century, beginning in 1879.
L-phenylalanine is an essential amino acid, meaning that it is vital to humans but cannot be synthesized by the body.  L-phenylalanine is used primarily for the synthesis of proteins, although it also serves many direct biochemical functions. It is found in many foods, especially meat and dairy products. Other sources of L-phenylalanine include green leafy vegetables.
D-phenylalanine isn't an essential nutrient, although it's one of the few D-enantiomers of amino acids that's pharmacologically active. This activity is generally due to inhibition of the action of enzymes. D-phenylalanine is generally not found in nature and is only produced in the laboratory.
 
A mixture of more than one enantiomer of the same chemical is called a racemic mixture. Phenylalanine is commercially available in racemic form, commonly referred to as DL-phenylalanine. Each enantiomer of phenylalanine offers different health benefits.
 

Uses of DL-Phenylalanine

Health uses of DL-phenylalanine generally relate to its neurotransmitter effects. Typical uses include relieving discomfort, supporting healthy energy levels, and stress management.

Signs that you need DL-phenylalanine

Chronic discomfort is one of the main signs that you need DL -phenylalanine supplements, especially if it's due to infection or injury. Low energy levels and sleep disturbances are also indications that you may benefit from DL-phenylalanine. Conditions that deplete the body's natural supply of neurotransmitters may mean you need DL-phenylalanine. These include stress and the use of drugs such as caffeine and nicotine.
