L2 PubMed 確有 2023 年正向統合分析（7 RCT, n=325, SMD -0.919），但樣本規模偏小且異質性高；2019 年傘狀回顧明確指出鎂介入研究 36 項 RCT 中僅 12 項達顯著，品質參差。
L5 四大患者面權威（Mayo/Cleveland/Harvard/APA-NIMH）一致採取謹慎或保留立場，Harvard 在憂鬱症補充劑專文中完全未列鎂、APA/NIMH 治療頁面亦未提及。
L4 監管層（FDA QHC 為高血壓而非憂鬱症、EFSA Article 13 涵蓋神經傳導但非憂鬱症療效宣稱、WHO 僅核可子癇前症）均未支持鎂作為憂鬱症治療。
整體呈現「小型 RCT 訊號正向 + 主流臨床機構保留」的弱證據格局。

Magnesium, in any form, might help with anxiety and depression, as it is necessary to make serotonin, a neurotransmitter that affects mental health and mood. While magnesium is often marketed to help with relaxation, sleep and mood, it hasn't been proven in human studies. 來源↗

Unless you have a diagnosed or suspected magnesium deficiency, or a condition with clear evidence of benefit such as preeclampsia or Crohn's disease, there's no compelling reason to routinely take a magnesium supplement. Many studies of the potential benefits of magnesium are quite small, and some have inconsistent results. 來源↗

Research increasingly demonstrates that whole foods and nutrient-dense diets are likely to provide better mental health outcomes than supplementation of isolated nutrients. Dietary supplements should be considered only as adjuncts to conventional care and used cautiously, ensuring no contraindications with prescribed psychotropic medications. 來源↗

TW 社群普遍將鎂視為改善睡眠、放鬆情緒、緩解焦慮的輔助營養素，少數憂鬱症恢復分享文會把鎂與 omega-3、鈣、B 群並列為「營養療法」一環，但鮮少有人把鎂單獨當作憂鬱症的主要治療方式；多數網友仍強調仍須配合身心科藥物、運動與睡眠調整。
💬社群實感
意見分歧
破解迷思 社群最常見的 5 個誤解
✓
事實誤以為鎂可以取代抗憂鬱藥(SSRI/SNRI)，但社群實際經驗多半只把鎂當輔助
✓
事實把包裝上的化合物 mg 數當成元素鎂含量，導致實際補充劑量遠低於有效範圍
✓
事實認為氧化鎂便宜又有效，忽略其吸收率僅約 4% 且主要作用是軟便、通便
✓
事實把『鎂能助眠 → 能治憂鬱症』直接劃等號，忽略憂鬱症需專業診斷與多面向治療
✓
事實認為鎂屬於礦物質就完全沒有副作用、可隨意大量補充
🩹 社群通報的副作用
- 腹瀉、軟便（特別是氧化鎂或劑量過高時）
- 服用鈣鎂鋅後心跳加快、心悸感
- 白天嗜睡、精神不集中
- 腸胃不適、輕微噁心
- 大劑量時可能出現頭暈、意識模糊
