What are minerals?

Minerals are natural compounds or elements in the crust. Also known as inorganic salts, it is the general name of inorganic substances in human body. It is the general name of various elements that constitute human tissues and maintain normal physiological functions, and it is one of the seven essential nutrients for human body.

Minerals, like vitamins, are essential elements for human body. Minerals cannot be produced and synthesized by themselves, and the daily intake of minerals is basically determined, but it varies with age, gender, physical condition, environment, working conditions and other factors.

The total amount of minerals in the human body is less than 5% of the body weight. They can't provide energy, but they can't be synthesized by themselves in the body. They must be supplied by the external environment, which plays an important role in the physiological function of human tissues. Minerals are important raw materials for human tissues. For example, calcium, phosphorus and magnesium are the main raw materials for bones and teeth.

3. There are synergistic or antagonistic effects between mineral elements;

4. The requirement of some minerals is very small, and the range between physiological requirement and toxic dose is very narrow, and excessive intake is easy to cause poisoning.
