B 🟡 B 初步證據 證據分歧 ⚠️ medium — moderate promotional content
證據強度極為一致且高品質:Cochrane 系統性回顧(10 RCTs)顯示「remarkably effective」,2021 統合分析量化效果(SMD -0.66 至 -0.76);AASM 以最高證據等級 Standard 推薦;EFSA 核可健康宣稱(0.5 mg 出發日睡前);NIH/NCCIH 與四大 patient-facing 機構(Mayo、Cleveland、Harvard、Sleep Foundation)一致給予 supportive 立場。
劑量與時機(低劑量 0.5–3 mg、目的地就寢前)跨來源高度收斂。
唯一保留是台灣法規層面(處方藥),但與療效證據強度無關。

short-term use of melatonin supplements appears to be safe 來源↗
L5b Mayo Clinic
支持
Evidence shows that melatonin can improve jet lag symptoms, such as alertness and daytime sleepiness. Taking a relatively low dose of melatonin (0.5 milligrams) — one of the strengths available over the counter — also has been shown to be effective. 來源↗
L5c Cleveland Clinic
支持
If you experience any of these disorders, or if you've got jet lag, melatonin can be a good supplement to get you back on track. 來源↗
L5d Harvard Health
謹慎
Some small studies have suggested that melatonin is helpful for jet lag if taken a few days before and after travel. Melatonin has been more effective at treating eastward jet lag, and so might be more helpful to you on the outbound trip—when taken close to the target bedtime. 來源↗
L5e Specialty Society (condition-mapped)
支持
Melatonin administered at the appropriate time is indicated to reduce symptoms of jet lag and improve sleep following travel across multiple time zones. 來源↗

📍立場總覽
TW 社群(PTT、Dcard、Mobile01)對褪黑激素用於調整時差普遍持正面態度,多數使用者表示效果不錯,但提醒應從 1-3mg 低劑量開始嘗試;台灣屬處方藥不易取得,社群多分享自 iHerb 海外購買管道。
💬社群實感
多數正面
破解迷思 社群最常見的 5 個誤解
✓
事實誤以為劑量越高越有效(其實 1-3mg 已足夠,10mg 反而易爆睡與隔日疲倦)
✓
事實誤以為可當長期失眠用藥(社群與醫師均建議僅用於短期時差調整)
✓
事實誤以為和安眠藥一樣強效(褪黑激素僅是助眠訊號,對重度失眠效果有限)
✓
事實誤以為在台灣是保健食品(實際上是處方藥,iHerb 因海關政策不一定能寄達)
✓
事實誤以為吃了立即想睡(其實需睡前 30 分鐘服用並關燈才有效)
🩹 社群通報的副作用
- 白天嗜睡、睡不醒
- 多夢、做惡夢或鮮明夢境
- 睡醒缺乏睡飽感、仍覺疲累
- 高劑量導致長時間爆睡(如半顆 10mg 睡四小時)
- 停用後可能依賴心理感
