비타민 D 관련 상기도 감염
A 근거 여러 대규모 임상 시험이 일관되게 유의미한 효과를 보여줍니다.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.
