What does it do?

L-phenylalanine is an essential amino acid that the human body cannot synthesize on its own. It is primarily required for protein synthesis and the production of neurotransmitters. In pharmaceuticals, it is used for nutritional supplementation, especially to provide essential amino acids to patients in need of nutritional support.

L-phenylalanine is used in the body for protein synthesis and acts as a precursor to the neurotransmitters dopamine and norepinephrine. This helps maintain and restore bodily functions. By supplementing essential amino acids in the state of nutritional deficiency, it supports normal metabolic processes.

Approved uses differ by product. Check each product's information for its actual use.
