The correct calcium supplement methods are medicine supplement and food supplement. According to the severity of calcium deficiency, choose the appropriate supplement method under the guidance of doctors.

1. If the calcium deficiency is serious, it is recommended to supplement it with drugs. Appropriate calcium agents, such as calcium carbonate or calcium gluconate, can be used under the guidance of a doctor.

2. If the calcium deficiency is not particularly serious, it is recommended to supplement it with food. You can eat more calcium-containing foods, such as milk or soy products. You can also eat more fresh fruits and vegetables in your diet, such as shrimp, kelp, dried fish and other foods with high calcium content. These are all calcium supplements.

It is also important to supplement calcium correctly, that is, often going outdoors to bask in the sun can promote the formation of vitamin D, which in turn can promote the absorption of calcium, thus effectively supplementing calcium.
