Minerals can constitute important tissues of the human body, including bones and teeth. Among them, magnesium, copper, phosphorus, manganese and calcium, if lacking these minerals, can easily loosen bones and teeth.

For example, iodine deficiency in thyroxine and hemoglobin are closely related to iron.
Minerals can also maintain the acid-base balance of human body and the effective osmotic pressure of tissues and cells. In addition, minerals can also maintain the permeability of cell membrane and maintain the exciting function of various muscles.
