N-Acetyl L-Tyrosine has emerged as a key ingredient in the nootropic and sports nutrition segments, driven by consumer demand for cognitive enhancers and stress-management solutions. Formulators favor it over plain L-tyrosine for its superior water solubility and stability, making it easier to incorporate into capsules, tablets, and functional beverages. As the market for mental performance products expands, this acetylated amino acid continues to gain traction among brands targeting focus, alertness, and resilience under stress.
N-Acetyl L-Tyrosine is the acetylated form of the essential amino acid L-tyrosine, which serves as a direct precursor to the catecholamines dopamine, norepinephrine, and epinephrine. While L-tyrosine itself is poorly soluble, acetylation yields a derivative that dissolves readily in water and resists degradation during processing and storage. This makes it a practical choice for manufacturers seeking a reliable, bioavailable tyrosine source for their formulations.
Our N-Acetyl L-Tyrosine is produced via enzymatic acetylation of L-tyrosine, followed by purification and crystallization. We offer a consistent, high-purity grade (≥98% by HPLC) with low heavy metals and tight particle size control. Each batch is tested for identity, assay, and residual solvents to meet the stringent requirements of dietary supplement and pharmaceutical applications.
N-Acetyl L-Tyrosine is a white crystalline powder with a molecular weight of 223.23 g/mol. It is chemically stable under normal storage conditions, though it should be protected from moisture and direct light. The compound is freely soluble in water (approximately 10 mg/mL at 25°C), which facilitates uniform dispersion in aqueous systems.
As a derivative of L-tyrosine, it retains the phenolic side chain essential for neurotransmitter synthesis. Upon ingestion, it is rapidly deacetylated to L-tyrosine, ensuring a steady supply of the precursor without the solubility limitations of the parent amino acid.
