碘 Iodine × 橋本氏甲狀腺炎
結論：證據支持但有警示
碘×橋本氏甲狀腺炎屬於典型 U 型風險關係：碘為甲狀腺激素合成必需營養素，但對已具遺傳易感性或已確診橋本氏患者，過量碘攝取（特別是 kelp、海帶錠、高劑量單方碘）已被多源證據（2025 PubMed 系統性回顧 74 篇研究、2003 RCT、Mayo Clinic、Harvard Health、ATA、NIH ODS、TFDA）一致認定為誘發或惡化因子。

L2 證據為系統性回顧級別但無大型 RCT，多數證據屬觀察性或機制性；補充碘對橋本氏並無治療效益，反而具明確風險，故獨立評為 C（弱證據／風險>益處），標準治療仍為左甲狀腺素替代而非補碘。

Iodized salt or iodized table salt is the article of commerce, salt for human food use, to which has been added cuprous iodide or potassium iodide.

Adults need 140 micrograms (μg) of iodine a day. Most people should be able to get all the iodine they need by eating a varied and balanced diet. Taking high doses of iodine for long periods of time could change the way your thyroid gland works. This can lead to a wide range of different symptoms, such as weight gain. Taking 0.5mg or less a day of iodine supplements is unlikely to cause any harm. 來源↗

台灣社群（PTT、Dcard、PIXNET 病友部落格）對橋本氏患者補碘多採「謹慎甚至避免」立場，主流共識為限碘飲食、避吃海帶昆布紫菜海苔；少數受國外功能醫學影響者嘗試補碘，多數回報出現不適反應。
💬社群實感
多數負面
破解迷思 社群最常見的 5 個誤解
✓
事實誤以為橋本氏就是甲狀腺低下，須像缺碘地區一樣補碘
✓
事實把昆布湯、海帶排骨湯當養生湯品天天喝
✓
事實誤把橋本氏與甲狀腺癌術後低碘飲食混為一談
✓
事實聽信國外功能醫學書籍（如《缺碘大危機》）自行高劑量補碘
✓
事實以為只要吃 Eltroxin（昂特欣）就可隨意吃海鮮海藻
🩹 社群通報的副作用
- 自行補碘後心悸、焦慮、失眠
- 皮膚出疹、痘痘惡化（被部落客稱為溴化物排毒反應）
- 吃完海帶火鍋後脖子腫脹感加重
- TSH 不穩、抗體 anti-TPO 升高
- 搭配甲狀腺素藥物時症狀波動更明顯
