Calcium is one of the important elements needed by the human body.

Calcium supplementation is needed at many stages in a person's life.

Different age groups have different needs for calcium. The daily calcium requirement for adults in my country is 800 mg.

Three meals a day can provide 400-500 mg of calcium. If milk, various dairy products, soy products and other foods are added, the daily calcium requirement can generally be met.

As the saying goes, "medicinal supplements are not as good as dietary supplements." In fact, there are many foods high in calcium around us.

Milk in natural food contains 100-120 mg of calcium per 100 grams. Each bag of commercial milk contains about 240-280 mg of calcium. It is easily absorbed by the body and is the most ideal source of calcium.

If a child drinks 250 ml of milk and a cup of yogurt every day, it can supplement 400-500 mg of calcium, and supplemented with calcium-rich vegetables, soy products, etc., it can basically meet the calcium needs.

Beans, fish and shrimp, hazelnuts, peanuts and other dried fruits, kelp, fungus, mushrooms, sesame paste and many green vegetables are all good sources of calcium.
