Vitamin D need in children

  As we know, severe vitamin D deficiency may cause rickets in infants or children. Although rickets is not common now, it was reported that 96% children with rickets were breastfed, since breast milk contains inadequate vitamin D. The American Academy of Pediatrics 2008 recommended infants who were exclusively or partially breastfed required 400 international units vitamin D daily from the first few days of life.
  Recently doctors paid more attention to subclinical vitamin D deficiency because insufficient vitamin D status may correlate with several extra-skeletal effects, such as pregnancy-related complications and immune dysfunction. It has been known that vitamin D receptors are present all over the body, so the researches regarding system-based vitamin D effects, the possible risk factors leading to vitamin D deficiency, and the recommendations of vitamin D requirements will be discussed.
  Medical advice for vitamin D supplementation should be individualized accordingly. Many pediatricians and physicians recommend appropriate vitamin D supplementation instead of sunlight over-exposure to achieve optimal plasma concentration.
