비타민 C 관련 상기도 감염
B 근거 적어도 하나의 무작위 시험이 이를 지지하며, 대체로 일관된 결과를 보입니다.Research suggests regular vitamin C supplementation may reduce cold duration by approximately 8% in adults and 14% in children. Supplementation at 1g+/day is associated with reduced severity of cold symptoms. Notably, vitamin C started after symptom onset does not appear to be effective.
