Vitamin D plays a crucial role in maintaining blood calcium levels and bone mineralization. Active vitamin D enhances the absorption of calcium in the body. Most of the calcium ions help maintain normal blood concentrations and promote bone mineralization, thereby increasing bone strength. In children, this supports proper growth and development.
