鐵×ADHD 證據呈現「條件式 cautious」格局:2024 Elliott SR/MA(3 RCT, n=124)顯示補鐵組過動效應量大 (d=1.70) 但組間差異未達統計顯著,整體 GRADE 評為 very low;2025 Fiani MA (n=1408) 在非貧血族群顯示鐵可改善焦慮、疲勞、認知 (d=0.34-0.46) 但未改善注意力。
CHADD 與 Mayo 均明確表態「僅對確認缺鐵者補充,不可作為 ADHD 主治療」,Cleveland 與 Harvard 對此題未表態。
鐵本身有兒童過量致死風險(FDA 強制警語)。
整體不足以給 B 但有正面條件式訊號,給 C。

Frequently, the elements zinc, magnesium, and iron are studied in relationship to ADHD. One should treat a deficiency but not depend on these substances to correct ADHD. These elements shouldn't be taken in large doses or by people who don't have a deficiency, as that could lead to other health problems. 來源↗

TW 社群(PTT Child_Psy、BabyHome、Dcard 心理板)普遍認知「鐵是多巴胺合成的輔助因子」,過動兒若血清鐵蛋白偏低可能加重注意力與衝動症狀,多數家長分享傾向先驗血再補鐵,並強調這只是輔助、不能取代正規藥物治療。
💬社群實感
意見分歧
破解迷思 社群最常見的 5 個誤解
✓
事實以為補鐵就能取代 ADHD 藥物(利他能、專思達)
✓
事實把『過動兒一定缺鐵』當成定論,忽略需先驗血確認
✓
事實誤認鐵劑越多越好,忽略過量會便祕、噁心甚至中毒
✓
事實把『鐵蛋白低』直接等同於『缺鐵性貧血』,但兩者判讀不同
✓
事實認為吃保健食品(綜合維他命含微量鐵)就足以矯正缺鐵
