L-Phenylalanine Amino Acid Ingredient

Product Overview

L-Phenylalanine is an essential aromatic amino acid used as a nutritional ingredient in dietary supplements, sports nutrition products, and functional formulations. It is valued by formulators for its role in protein synthesis and amino acid nutrition, making it a widely used raw material for capsules, tablets, powders, and amino acid blends.

L-Phenylalanine belongs to the essential amino acid family, meaning it cannot be synthesized by the human body in sufficient amounts and must be obtained through dietary sources or supplementation. As a high-purity nutritional ingredient, it is commonly produced through fermentation technology for food and supplement applications.

What Is L-Phenylalanine?

L-Phenylalanine is the naturally occurring L-isomer of phenylalanine, an aromatic amino acid involved in normal protein metabolism. It serves as a nutritional building block and is commonly incorporated into amino acid formulas, sports nutrition products, and general wellness supplements.

Due to its stable chemical properties and compatibility with other nutritional compounds, L-Phenylalanine is suitable for various supplement formats, including powder blends, hard capsules, tablets, and customized formulations.
