Factory Supply 99% L-Tyrosine CAS 60-18-4
What is L-Tyrosine?
L-Tyrosine (Tyr) is an essential amino acid that plays a crucial role in the metabolism, growth, and development of humans and animals. It is widely used in the food, feed, pharmaceutical, and chemical industries. It is often used as a nutritional supplement for patients with phenylketonuria and as a raw material for the preparation of various pharmaceutical and chemical products. With the discovery of more high-value-added L-Tyrosine derivatives such as danshensu, resveratrol, and hydroxytyrosol in vivo, L-Tyrosine is increasingly becoming a platform compound.

What are the benefits of L-tyrosine?
Neurotransmitter synthesis
L-tyrosine is a precursor to neurotransmitters such as dopamine, norepinephrine, and epinephrine. These neurotransmitters are crucial for mood regulation, attention, cognitive function, and the ability to cope with stress.
Thyroid hormone synthesis
L-tyrosine participates in the synthesis of thyroid hormones, helping maintain normal metabolic function, body temperature regulation, and energy levels.
Melanin synthesis
L-tyrosine is a building block for melanin synthesis, helping maintain healthy pigmentation in the skin, hair, and eyes.
Supporting athletic performance and recovery
In sports nutrition, L-tyrosine is believed to help reduce fatigue, improve endurance, and accelerate recovery, especially during high-intensity or prolonged exercise.
Potential anxiolytic and antidepressant effects: By supporting the synthesis of neurotransmitters, L-tyrosine may help alleviate symptoms of anxiety, depression, and chronic fatigue.
What are the uses of L-tyrosine?
Nutritional Supplements
It is commonly used in health supplements to improve mental well-being, relieve fatigue, and boost immunity.
Sports Nutrition: It is added to products such as protein powders and energy bars to help athletes improve performance, reduce fatigue, and accelerate recovery.
Functional Foods: It is added to energy drinks and nutritional supplements to enhance overall health.
Skin Care
Anti-Aging and Whitening: L-tyrosine, due to its antioxidant properties, is added to anti-wrinkle creams and whitening products to help reduce wrinkles and brighten skin.
Food Additives
Food Flavor Enhancer: L-tyrosine has umami properties and can be used to enhance the taste and flavor of foods such as meat products and condiments.
Medical Fields
Treatment of Neurological Disorders: As a precursor to neurotransmitters such as dopamine and norepinephrine, L-tyrosine is used to improve cognitive function, combat stress, and treat certain neurodegenerative diseases.
Thyroid Function Support: It participates in thyroid hormone synthesis and is used as an adjunct to the treatment of thyroid dysfunction.
Is L-tyrosine effective for treating gray hair?
Modern research indicates that insufficient tyrosinase activity is a major cause of melanin loss in hair. Tyrosinase requires L-tyrosine as a raw material to synthesize melanin. Therefore, supplementing with L-tyrosine is believed to help restore hair pigmentation. L-tyrosine is an essential amino acid involved in the synthesis of melanin and neurotransmitters such as dopamine and norepinephrine.
When tyrosinase activity decreases, lack of sufficient L-tyrosine as a substrate disrupts the melanin synthesis chain, resulting in gray hair. Moderate L-tyrosine supplementation can provide sufficient raw material for tyrosinase and support hair pigmentation.
Nutritional supplements based on L-tyrosine are also available, typically as dietary supplements. Compared to food, capsules or powders offer the advantage of a more concentrated dose and are easier to take. However, it's important to note that they are not a panacea for darker hair and should only be used as part of a comprehensive nutritional regimen.
