%X objective: to determine if there is evidence of clinical benefit for vitamin d supplementation in infants. sources: medline data base and evidence based medicine electronic sites. review methods: a search for clinical practice guidelines, meta-analyses, systematic reviews, evidence-based reviews and clinical trials published before january 2010, in english, french, spanish and portuguese was performed using the mesh terms: £¿vitamin d£¿ and £¿dietary supplements£¿. the strength of recommendation taxonomy scale of the american family physician was used to assess the quality of the studies and the strength of the recommendation. results: we identified 340 articles, but only nine met all of our inclusion criteria. these consisted of three clinical practice guidelines, two systematic reviews, an evidence-based review, a consensus statement of two experts and one cohort study. no agreement was found regarding the need for vitamin d supplements or the recommended dose. vitamin d supplementation with 400 iu per day for all infants who are exclusively breastfed or who ingest less than one liter of formula milk per day seems beneficial and safe. conclusion: currently, the most common recommendation for preventing rickets is the provision of 400 iu of vitamin d per day to infants who are exclusively breastfed, or who are fed with at least one liter of milk a day. additional controlled, randomized, long-term high quality studies are necessary to assess the need for vitamin d supplementation in different populations.
