Can vitamin D prevent acute respiratory infections?
Can vitamin D prevent acute respiratory infections? A systematic review and meta-analysis says Yes, but the dosages used may not be what you'd expect. PRACTICE CHANGER: Reduce acute respiratory tract infections in those with significant vitamin D deficiency (circulating 25-hydroxyvitamin D levels < 10 ng/mL) with daily or weekly vitamin D supplementation--not bolus vitamin D treatment. STRENGTH OF RECOMMENDATION A: Based pm a systematic review and meta-analysis of 25 trials.
