L-tyrosine (Tyr) is an essential amino acid that plays a vital role in the metabolism, growth, and development of humans and animals, and is widely used in the food, feed, pharmaceutical, and chemical industries. It is commonly used as a nutritional supplement for patients with phenylketonuria (PKU) and as a raw material in the preparation of pharmaceutical and chemical products such as polypeptide hormones, antibiotics, L-DOPA, melanin, p-hydroxycinnamic acid, and p-hydroxystyrene. Furthermore, with the discovery of more high-value-added L-tyrosine derivatives such as tanshinone, resveratrol, and hydroxytyrosol in vivo, L-tyrosine is increasingly developing towards platform-type compounds.

L-Tyrosine plays a crucial role in neurotransmitter synthesis and mood regulation. As a direct precursor to catecholamine neurotransmitters such as dopamine, norepinephrine, and epinephrine, it can increase the levels of these neurotransmitters in the brain, improving attention and stress resistance. By supporting neurotransmission function, it helps alleviate mild depression, anxiety, and chronic fatigue.
Supporting Thyroid Hormone Synthesis: As a structural component of thyroid hormones (T3, T4), an adequate supply of L-tyrosine is essential for maintaining normal metabolism, thermoregulation, and growth and development. Patients with hypothyroidism often need to ensure adequate intake.
Promoting Melanin Production: L-tyrosine is the starting substrate for melanin synthesis, gradually converting into melanin under the catalysis of tyrosinase, affecting the color of skin, hair, and eyes. Deficiency may lead to hypopigmentation or premature graying of hair.
Antioxidant and Stress Protection: Its metabolites, such as dopamine, have a certain free radical scavenging ability, which can reduce oxidative stress damage. Under physiological or psychological stress, the demand for L-tyrosine increases; supplementation helps maintain neuroendocrine balance.
Health supplements for improving mood and cognition: Used as dietary supplements to relieve stress, enhance focus, and improve mood. Often used as an adjunct treatment for mild depression or anxiety, frequently combined with ingredients such as serotonin.
Whitening and hair care products: Used in skincare products as a regulator of whitening ingredients, achieving skin brightening by modulating melanin metabolism. Used in anti-gray hair or hair care products to help maintain normal hair pigmentation.
Sports nutrition and special medical uses: Added to sports nutrition products to enhance athletic performance and anti-fatigue capabilities by supporting catecholamine synthesis.
For some products that require special packaging during transportation, we will carry out more delicate packaging. For example, retinal needs to be stored at -20 °C, so we choose cold chain transportation during transportation; deoxyarbutin will change color during transportation, so we will Vacuum packing of deoxyarbutin
