Vitamin D is necessary for normal bone growth and development in children.
The recommended daily needs for vitamin D for infants 0 to 6 months are 7.5 micrograms (300 IU) and for children 6 months to 10 years is 10 micrograms (400 IU).
According to experts, adolescent children with risk factors for vitamin D deficiency and who do not obtain 400 IU / day with the intake of one liter of fortified milk or fortified foods or adequate sun exposure, should receive a vitamin D supplement from 400 IU / day.
