Adequate vitamin D in children’s growth to ensure the healthy bone development. The American Medical Institute (IOM) and the British Council for Nutritional Science believe that serum levels of vitamin D <30 nmol / L and <25 nmol / L are indicative of vitamin D deficiency and increased risk of skeletal disease.
