In most cases, children do not need to take calcium supplements all the time because they only need to take extra calcium supplements when they are growing very rapidly, such as during infancy or adolescence, when growth is particularly rapid and weight and height growth are relatively fast. If children are not given calcium supplements in time, they will often suffer from calcium deficiency and it is necessary to give them calcium supplements at this time. Other developmental stages of children, as long as they drink enough milk and eat meat and beans properly, will rarely cause calcium deficiency, and there is no need for additional calcium supplementation, so children do not need to take calcium supplements all the time.
