Threonine is one of the essential amino acids for the human body. It cannot be synthesized by the body and must be obtained from food. Its core functions mainly manifest in maintaining normal physiological functions of the body, promoting growth and development, and ensuring metabolic balance, among other key aspects.

1. Construction and repair of body tissues

Threonine is an important component of proteins and participates in the synthesis of various proteins in the body. It is crucial for the construction and repair of body tissues. It can provide raw materials for the growth of tissues such as muscles, skin, hair, and bones. Especially during injury repair (such as wound healing) and muscle recovery after exercise, threonine can accelerate the regeneration and repair of damaged tissues, helping to maintain muscle mass and body functions.

2. Regulation of protein metabolic balance

Threonine participates in the synthesis and catabolic regulation of proteins in the body and can work in synergy with other amino acids to maintain nitrogen balance. When there is an adequate supply of threonine in the body, it can reduce protein breakdown and promote the effective utilization of proteins, avoiding the use of tissues such as muscles as energy sources. This is of great significance for maintaining metabolic efficiency and preventing malnutrition.

3. Support immune system function

Threonine is a necessary raw material for the synthesis of immunoglobulins (antibodies). Adequate threonine can promote the proliferation of immune cells and the production of antibodies, enhancing the body's resistance to pathogens. At the same time, it can participate in the repair and renewal of intestinal mucosal cells, maintaining the integrity of the intestinal barrier, reducing the occurrence of intestinal diseases, and indirectly improving the overall immune level.

4. Promote fat metabolism and liver function protection

Threonine can promote the metabolism and transport of fat in the liver, reduce fat accumulation in the liver, and lower the risk of fatty liver. In addition, it can participate in the synthesis of certain enzymes in the liver, enhance the liver's detoxification function, protect liver cells from damage, and maintain normal liver physiological functions.

5. Assist in maintaining nervous system health

Threonine can be converted into precursor substances such as glycine for neurotransmitters in the body, participating in the transmission of neural signals, which helps maintain the normal function of nerve cells, improve nerve conduction efficiency, and alleviate nerve fatigue, supporting normal cognitive and reaction abilities of the brain.
