Nutrition that people who exercise often lack:

1. Magnesium. Magnesium can promote the release of insulin, promote muscle growth, relieve blood vessel tension, protect cardiovascular systems, and reduce headaches after exercise.

2. Iron. It helps form hemoglobin and provides the blood with its ability to carry oxygen.

3. Calcium. Muscle contraction during exercise will increase calcium consumption, so calcium deficiency is more common among bodybuilders.

4.VC. Exercise aggravates oxidative reactions in the body. Pay attention to your own nutrition after exercise.
