鋅 Zinc × 傷口癒合

L2 收錄 2020、2025 兩篇正向 MA（Song 2020 壓力性損傷、2025 新版 MA 顯示 MD 1.41, 95% CI 1.04-1.92），加上 2017 糖尿病足 RCT 顯示鋅補充改善癒合與代謝，方向一致支持鋅對潰瘍癒合有幫助；但 GRADE 證據等級僅為中等，受限於樣本小、方法學品質參差，且效益主要集中在『缺鋅或嚴重傷口（壓瘡、糖尿病足、燒傷）』族群，對血鋅正常者效益未顯示。
Harvard、Mayo、WoundSource 皆強調此族群限制，且高劑量（100-300 mg/day）反可能干擾銅鐵代謝、破壞膠原交聯而阻礙癒合。
整體屬中等證據、需限定族群與劑量，給 B 級。

The greatest benefit of zinc appears to be in people who are deficient in the mineral and who have severe wounds such as decubitus ulcers or extensive burns. A benefit of zinc supplementation has not been shown in people with skin ulcers who have normal blood levels of zinc. 來源↗

謹慎
Unless clinical signs of a zinc deficiency are suspected or can be confirmed in clients with wounds, supplementing with high doses of elemental zinc is not recommended. Consuming high levels of supplemental zinc in the range of 100-300mg per day for long periods of time may result in reduced copper and iron status, disruption of collagen cross-linking and may hinder wound healing. 來源↗

TW 社群普遍認為鋅有助於皮膚修復、傷口（嘴破、痘痘、車禍擦傷、疤痕）癒合，常與維他命 C、B 群一同補充；但提醒空腹吃會胃痛、過量易頭痛噁心，仍建議飲食優先。
💬社群實感
多數正面
破解迷思 社群最常見的 5 個誤解
✓
事實以為吃越多鋅傷口好越快（實際過量易噁心、影響銅吸收）
✓
事實把口服鋅與外用氧化鋅藥膏功效混為一談
✓
事實誤以為素食者一定要額外補鋅（飲食均衡多半足夠）
✓
事實認為螯合鋅一定優於一般鋅，且越貴越有效
✓
事實以為鋅可單獨加速疤痕淡化（需搭配維他命 C、防曬等）
🩹 社群通報的副作用
- 空腹服用胃痛、噁心想吐
- 頭痛、頭暈（多於 30 mg 劑量）
- 長期過量導致掉髮
- 與鐵劑、鈣片同服互相干擾吸收
- 便秘或腸胃不適
