Bioidentical, essential L-form of phenylalanine

Phenylalanine is an amino acid, a building block of the protein. There are three forms of phenylalanine: D-phenylalanine, L-phenylalanine, and the mixture produced in the laboratory called DL-phenylalanine. D-phenylalanine is not an essential amino acid. Its role in the human organism has so far only been sparsely researched. L-Phenylalanine is a highly bioavailable essential amino acid. It is the only form of phenylalanine found in proteins.

Functions of L-phenylalanine in the body

The body naturally converts L-phenylalanine in the liver into the amino acid L-tyrosine. Once L-tyrosine has passed the blood-brain barrier, it is converted into L-DOPA. The decarboxylation of L-DOPA leads to the synthesis of the neurotransmitter dopamine.
The enzyme dopamine-beta-hydroxylase transforms dopamine into the neurotransmitters noradrenalin and adrenalin. This triad of neurotransmitters is called catecholamines.

L-phenylalanine stimulates the production of the thyroid hormones T3 (triiodothyronine) and T4 (thyroxine), which are essential for maintaining overall physical and cognitive health.

L-phenylalanine sources in food

Phenylalanine is found in protein-rich foods such as soybeans, cheese, nuts, seeds, beef, lamb, chicken, pork, fish, eggs, dairy products, beans and whole grains. The artificial sweetener aspartame also contains phenylalanine.
