Calcium is a natural decompression substance. People who lack calcium are always tired and nervous, and the fatigue caused by work cannot be alleviated. Don't forget to add magnesium while eating foods rich in calcium such as milk and yogurt. "Calcium supplementation does not supplement magnesium, and you will regret it if you eat it!" Fresh wheat germ, buckwheat, walnuts, almonds, red wine, bananas, laver, unprocessed honey and soybeans are all rich in magnesium.
