      Product Application  


    (1) In the pharmaceutical field, it can be used to prepare compound amino acid infusions and nutritional preparations, assisting in the treatment of protein deficiency and other conditions.

    (2) In the food industry, it is added as a nutritional fortifier to infant food, health food, etc., to enhance their nutritional value.

    (3) In the feed industry, it is an important additive in livestock and poultry feed. It can promote animal growth, improve feed utilization, and has a significant effect on the growth and development of poultry and pigs in particular.

    (4) In the cosmetics field, it can be added to skin care products as a nutritional ingredient, helping to maintain the normal metabolism and health of the skin, and enhancing the skin's moisturizing and repairing abilities.

    (5) In the field of biological research, it is often used in the preparation of culture media to provide essential nutritional support for the growth and reproduction of microorganisms, cells, etc., facilitating the conduct of related biological experiments and research.


      Product Function  


    (1) Participating in protein synthesis: As an essential amino acid for the human body, it is one of the basic units constituting proteins, providing raw materials for the growth, repair and renewal of body tissues (such as muscles, bones, internal organs, etc.).

    (2) Maintaining normal immune system function: It helps in the synthesis of immune-related proteins such as immunoglobulins, enhancing the body's immune function and improving resistance.

    (3) Promoting nutrient absorption and utilization: It can work synergistically with other amino acids to improve the utilization rate of protein in food and ensure the effective intake of nutrients by the body.

    (4) Supporting nervous system function: It participates in the synthesis and metabolism of certain neurotransmitters in the nervous system, and plays a certain auxiliary role in maintaining the normal operation of the nervous system.
