The basic unit of protein is amino acid. If the human body lacks any essential amino acids, it will lead to abnormal physiological functions, affect the normal metabolism of the body and eventually lead to diseases. Even if some non-essential amino acids are lacking, metabolic disorders will occur.
Suggestions for improving immunity:
1, usually eat more fruits and vegetables, and supplement vitamins, protein and amino acids appropriately.
2? do more exercise
3. Have a good sleep
