Product Overview

N-Acetyl-L-Tyrosine, CAS 537-55-3, is an acetylated derivative of L-tyrosine, presented as high purity white crystalline powder. It has better solubility than L-tyrosine and is widely used for amino acid fortification. As a precursor of neurotransmitters, this ingredient is commonly incorporated into dietary supplements and functional food formulations. It supports nutrient formulas for cognitive and mental wellness applications. Our N-Acetyl-L-Tyrosine meets food grade specifications, suitable for nutritional product manufacturing.

Key Characteristics

1.Superior Bioavailability & Solubility After acetylation modification, N-Acetyl L-Tyrosine overcomes the poor water solubility defect of ordinary L-Tyrosine. It dissolves rapidly in aqueous solutions and achieves higher absorption efficiency with lower effective dosage, ideal for liquid formulas and solid powder formulations.

2.Professional Neurotransmitter Precursor It is a direct and efficient precursor for synthesizing major catecholamine neurotransmitters, stably supporting human nervous system activity without causing excessive stimulation.

3.Stable Physical & Chemical Properties The modified molecular structure provides excellent temperature resistance and oxidation stability, suitable for high-temperature granulation, tableting, powder blending and various industrial processing technologies.

4.High Purity & Low Impurity Profile Strict industrial purification process ensures low heavy metal and residual content, fully meeting food, cosmetic and pharmaceutical grade safety standards.

5.Universal Global Compliance Consistent factory production specifications and complete international certifications support exports to Europe, America, Southeast Asia and other global markets.

Main Functions

1.Cognitive Function & Mental Focus Support N-Acetyl L-Tyrosine effectively promotes the synthesis of dopamine and norepinephrine, helping improve mental clarity, concentration and reaction speed. It relieves brain fatigue caused by long-term work, study and high-pressure environments, and supports stable mental state.

2.Physical Fatigue Relief & Stress Adaptation It assists the body in regulating stress hormone levels, alleviating physical exhaustion and mental tension caused by long-term exercise, overtime and high-intensity pressure, and improving overall body endurance.

3.Premium Sports Nutrition Enhancement Widely used in professional sports nutrition formulas to enhance exercise tolerance, reduce fatigue accumulation during high-intensity training, and support rapid physical recovery after exercise.

4.Biochemical & Cell Culture Raw Material Serves as an essential component of cell culture media and microbial culture media, applied in biopharmaceutical research, recombinant protein production and monoclonal antibody preparation.

5.Pharmaceutical Intermediate Synthesis Used for the synthesis of neuro-regulation preparations and amino acid health medicines, with high biological safety and formula compatibility.

Main Applications

1.Nootropic & Cognitive Dietary Supplements (Core Application) Applied in focus-improving capsules, brain health tablets, anti-fatigue nutritional powders and daily cognitive health functional foods, targeting office workers, students and high-pressure groups.

2.Professional Sports Nutrition Industry Added in pre-workout supplements, endurance enhancement powders, post-exercise recovery formulas and fitness nutrition tablets to support athletic performance and physical recovery.

3.Pharmaceutical Industry Used as a high-purity amino acid intermediate for neuroprotective preparations, nutritional injection formulas and biochemical pharmaceutical synthesis.

4.Biotechnology & Laboratory Research Widely used in cell culture medium, microbial fermentation medium and biochemical research experiments for biopharmaceutical and life science fields.

5.High-end Functional Food Fortification Applied in customized functional formula foods for anti-fatigue, energy supplement and mental state regulation.

ECHEMI Editorial Reference

N-Acetyl-L-tyrosine originates from tyrosine through an AA acetylase, is associated with aromatic L-amino acid decarboxylase deficiency and tyrosinemia I.
Solid
N-acetyl-L-tyrosine is an N-acetyltyrosine in which the chiral centre has L configuration. It has a role as an EC 2.1.1.4 (acetylserotonin O-methyltransferase) inhibitor, a biomarker and a human urinary metabolite. It is a N-acyl-L-tyrosine and a N-acetyltyrosine. It is a conjugate acid of a N-acetyl-L-tyrosinate.|N-acetyltyrosine, also referred to as N-acetyl-L-tyrosine, is used in place of as a tyrosine precursor. [DB00135] is a non-essential amino acid with a polar side group. N-acetyltyrosine is administered as parenteral nutrition or intravenous infusion due to its enhanced solubility compared to tyrosine. It is typically administered as a source of nutritional support where oral nutrition is inadequate or cannot be tolerated.

Our Quality

As a professional ingredient supplier, we do not operate manufacturing facilities. Instead, we build robust quality‑assurance workflows across our whole supply chain to safeguard consistent product performance for every shipment

Strict Supplier Due‑Diligence

Before entering any partnership, we carry out on-site factory visits and assess industry reputation, followed by multi-stage qualification reviews. We validate production qualifications, export track records, quality management systems and complete certification packages. New suppliers must pass sample evaluation, and only fully vetted top-tier factories are admitted to our approved supplier pool

Batch‑by‑batch Document Verification

For every order, we cross‑check factory‑issued test documents against agreed specifications including FCC, USP, EP, AJI, CP or your customized requirements. We will not forward documents to customers until key indicators are fully aligned with specifications. This step avoids inconsistent or mismatched documentation common in raw‑material trade.

Independent Third‑party Testing Coordination

Upon client request, we can arrange independent laboratory inspections from recognized third‑party institutions. We manage sample delivery, test protocol communication and report follow‑up to support your market compliance needs.

Quality Closure & Continuous Improvement

We keep traceable records for all delivered batches. If any quality concern arises, we act as your single point‑of‑contact to trace root causes with source factories, drive corrective actions and deliver practical resolution plans. Client feedback is systematically collected to optimize our supplier management and document‑review procedures.

We provide a comprehensive set of compliance documents to support your import and registration work. Our available documentation includes but is not limited to:
