Impact of two oral doses of 100000 IU of vitamin D3 in preschoolers with viral-induced asthma: a pilot randomised controlled trial

摘要

BackgroundNew evidence supports the use of supplemental vitamin D in the prevention of exacerbation of asthma; however, the optimal posology to sufficiently raise serum levels while maximising adherence is unclear. The objective was to ascertain the efficacy of high-dose vitamin D3 in increasing serum vitamin D in preschoolers with asthma and provide preliminary data on safety and efficacy outcomes.
