L-Tyrosine, a common amino acid with a vital role in human physiology, is increasingly recognized for its multifaceted benefits, particularly as a precursor to critical neurotransmitters and thyroid hormones. Understanding the scientific basis for its use is essential for formulators and researchers seeking high-quality ingredients. As a leading L-Tyrosine manufacturer and supplier in China, we provide a premium product that supports these vital biological functions.

At its core, L-Tyrosine (CAS 60-18-4) is an alpha-amino acid that serves as a fundamental building block in protein synthesis. However, its significance extends to being a direct metabolic precursor for the catecholamine family of neurotransmitters: dopamine, norepinephrine, and epinephrine. These compounds are synthesized through a cascade starting with tyrosine hydroxylase, the rate-limiting enzyme, converting L-Tyrosine to L-DOPA, which then leads to the production of dopamine and subsequently norepinephrine and epinephrine. These neurotransmitters are critical for regulating mood, attention, motivation, and the body's response to stress. Adequate L-Tyrosine availability is therefore crucial for optimal neurological function.

Furthermore, L-Tyrosine is an integral component in the synthesis of thyroid hormones, thyroxine (T4) and triiodothyronine (T3). The thyroid gland incorporates tyrosine residues into thyroglobulin, which are then iodinated and coupled to form these hormones, essential for regulating metabolism, growth, and development. This connection highlights L-Tyrosine's broad physiological impact.

The scientific literature underscores the benefits of L-Tyrosine, particularly in scenarios of stress or fatigue. Studies suggest that when the body is under significant pressure, the synthesis of catecholamines can be limited by tyrosine availability. Supplementation can help maintain cognitive and psychomotor performance by ensuring adequate neurotransmitter production. This makes L-Tyrosine a valuable ingredient for products targeting cognitive enhancement, stress resilience, and overall well-being.

For businesses, sourcing high-purity L-Tyrosine is paramount. Our manufacturing facility in China employs advanced fermentation techniques to produce L-Tyrosine with an assay of 99.0%-101.0%, adhering to international USP, EP, and JP standards.
