Amino acids are needed for the metabolism and synthesis of the human body. They can provide raw materials for the synthesis of proteins including enzymes and antibodies and many immune-functional cytokines. They can also be converted into carbohydrates and fats, or consumed by metabolism to produce energy.
For healthy people, we have normal digestion and absorption functions. Many of the foods we eat contain protein or amino acids. Protein can be digested into amino acids and then absorbed. Non-essential amino acids can also be synthesized in the human body. Most of us healthy people There are abundant amino acids in the body to maintain physiological functions including immune function.
For people who have obvious protein malnutrition and cannot eat normally, injecting amino acids to supplement the amino acids needed in the body can provide raw materials for maintaining normal physiological functions, including the functioning of the immune system, and may help immunity.
But for healthy people with a balanced diet, the body already has enough amino acids needed to maintain physiological functions, and then injecting amino acids is similar to continuing to refuel a car that has been filled with fuel, which will not make the car run more smoothly. Or running faster will increase the burden and risk of driving.
Therefore, for people who are severely malnourished and unable to eat normally for a long time due to various reasons, doctors can infuse nutrients including amino acids to supplement or maintain nutrition after assessing the condition to maintain physiological functions including immunity.
For those who can eat and drink without nutritional problems, it is not necessary. It will not make the immune system better if it is given. On the contrary, it may increase the nutritional burden and may also cause adverse reactions such as infusion reactions.
