In November 2008, the American Academy of Paediatrics (AAP) doubled the recommended daily intake of vitamin D for infants and children, from 200IU to 400IU. The study revealed that the use of oral vitamin D supplements was low (1-13%) and only 11-25% of American infants met the recommended level of 400IU per day. Both breastfed and formula-fed babies younger than six months of age are at risk of low vitamin D intake.
