L-Threonine is an essential amino acid for the human body and plays multiple important roles in the nutritional supplementation for the elderly, as follows:
I. Maintaining normal physiological functions of the body
Protein synthesis: L-Threonine is one of the basic units that make up proteins, which is crucial for the elderly to maintain muscle mass and enhance physical resistance. With the increase of age, the protein synthesis ability of the elderly's body declines. Supplementing L-threonine helps promote protein synthesis and maintain the normal physiological structure and functions of the body.
Tissue repair: The body tissue repair ability of the elderly weakens, and the recovery after surgery, trauma or illness is relatively slow. L-Threonine is involved in the repair and regeneration process of body tissues, which can help the elderly accelerate wound healing and promote physical recovery.
II. Enhancing immune function
Antibody synthesis: L-Threonine plays an important role in the immune system and is an important raw material for synthesizing antibodies such as immunoglobulins. Supplementing it can help the elderly maintain normal immune function, enhance the body's resistance to pathogens such as bacteria and viruses, reduce the risk of infectious diseases, and decrease the incidence frequency of diseases like colds and pneumonia.
Immune cell function: It helps maintain the normal metabolism and functions of immune cells, promotes the proliferation and differentiation of immune cells, enabling the immune system to better recognize and eliminate pathogens, thus improving the overall immune level of the elderly.
III. Improving cardiovascular health
Lowering blood lipid levels: L-Threonine can promote fat metabolism, help reduce the levels of cholesterol and triglycerides in the blood, and decrease the deposition of lipids on the vascular wall, thus contributing to the prevention of cardiovascular diseases such as atherosclerosis, which is beneficial to the cardiovascular health of the elderly.
Protecting the vascular endothelium: It helps maintain the integrity and normal functions of vascular endothelial cells, prevents damage to vascular endothelial cells, reduces the risks of inflammatory reactions and thrombosis, and thereby lowers the incidence of cardiovascular diseases.
IV. Regulating nervous system functions
Neurotransmitter synthesis: L-Threonine is a precursor substance of certain neurotransmitters, such as glycine. Glycine acts as an inhibitory neurotransmitter in the nervous system and is involved in regulating nerve signal transmission, which is essential for maintaining the normal functions of the nervous system. Supplementing L-threonine helps ensure the normal synthesis and release of neurotransmitters, maintain the stability of the nervous system, improve the nervous functions of the elderly, and prevent nervous system diseases.
Cognitive function: An appropriate amount of L-Threonine helps improve the cognitive function of the brain, enhance memory and attention, and plays a certain positive role in preventing the decline of cognitive ability in the elderly and diseases such as Alzheimer's disease.
V. Promoting digestion and absorption
Intestinal mucosa repair: L-Threonine is very important for maintaining the integrity and normal functions of the intestinal mucosa. It can promote the growth and repair of intestinal mucosal cells, enhance the barrier function of the intestine, prevent intestinal bacteria and toxins from entering the bloodstream, reduce the occurrence of intestinal infections and inflammation, and improve the digestion and absorption ability of the elderly.
Digestive enzyme secretion: It can also participate in regulating the secretion of digestive enzymes, promote the digestion and absorption of food, help the elderly better absorb nutrients from food, and improve the body's nutritional status.
