Vitamin D için Upper Respiratory Tract Infections

Lancet 2025 meta-analysis shows vitamin D supplementation may help protect against acute respiratory infections, with strongest effects in individuals with baseline 25(OH)D levels below 25 nmol/L. Optimal protective dosing appears to be 400-1,200 IU/day rather than intermittent bolus dosing.
