Respiratory infections reduced by 63 percent with 4000 IU vitamin D daily - RCT Dec 2012

Highlights of Report in Swedish translated by Google

  • Peter Bergman and his colleagues are fortunate to have 140 patients in daily treatment for one year with either vitamin D (4000 IU) or a placebo.
  • The study was double-blind: neither the patients - all of which were susceptible to infections - nor caregivers knew who belonged to which group before the trial was over.
  • The results show that vitamin D reduced patient discomfort.
  • The probability of requiring treatment with antibiotics during the study period was 63 % lower in the vitamin D group compared with the placebo group, and the incidence of fungal infections, including respiratory, decreased.
