비타민 A 관련 급성 설사
D 연구 예비 연구(실험실 연구, 증례 보고)만 존재합니다.비타민 A 결핍 인구에서 일부 근거가 있습니다. WHO는 홍역 관련 설사에 권장합니다. 결핍이 없는 사람에서는 효과가 없습니다.
결론
비타민 A 결핍 인구에서 일부 근거가 있습니다. WHO는 홍역 관련 설사에 권장합니다. 결핍이 없는 사람에서는 효과가 없습니다.

Safety & Side Effects
보고된 부작용
- ⚠ Hepatotoxicity at chronic high doses of preformed vitamin A
- ⚠ Birth defects (teratogenic at high doses during pregnancy — avoid >3,000 mcg RAE/day)
- ⚠ Nausea, headache, and dizziness
- ⚠ Bone density reduction with long-term excess
알려진 상호작용
- ● Retinoid medications (isotretinoin, tretinoin — additive toxicity risk)
- ● Orlistat (reduces absorption of fat-soluble vitamins)
- ● Alcohol (increases hepatotoxicity risk of vitamin A)
- ● Tetracycline antibiotics (increased risk of intracranial pressure)
일일 최대 섭취 허용량: 3,000 mcg RAE/day (preformed vitamin A; beta-carotene has no established UL)
