Abstract:
Vitamin D and its active metabolite 1,25 - dihydrooxyvitamin
D (1,25(OH) 2D) has been generally recognized as repertoire
of many classical (calcium balance and bone metabolism)
and non-classical effects (non-calcium actions) such as
promotion of insulin secretion and its action,
immunomodulation. Absorption of calcium and phosphorus
depends on sufficient vitamin D levels. Its low level leads
to demineralization of bone both in children and adults.
Vitamin D has also a significant role and has potential to
influence many factors in the developing fetus. Newborns
are at high risk of developing hypocalcaemic tetany as a
consequence of maternal deficiency of vitamin D.
