Answer

Recommended dietary intake of vitamin D for patients at risk of vitamin D deficiency is as follows [2] :

  • In infants and children up to 1 year old, at least 400 IU/day, to maximize bone health

  • In children and adolescents 1-18 years of age, at least 600 IU/day to maximize bone health

  • In adults 19-50 years of age, at least 600 IU/day to maximize bone health and muscle function

  • Raising the serum 25(OH)D level consistently above 30 ng/mL may require vitamin D intake of at least 1000 IU/day

  • Whether recommended levels of vitamin D intake will provide all the potential nonskeletal health benefits associated with vitamin D is currently unknown
