錳 Manganese × 骨折
結論：證據不足
錳對「骨折」此一臨床終點的人類證據為實質空白：L2 PubMed 全庫無任何以單方錳介入、以骨折發生率或骨折癒合為主要終點的 RCT，最常被引用的 Strause 1994 (n≈59) 為鈣＋鋅＋錳＋銅組合配方且僅測量腰椎 BMD（surrogate, 非骨折），錳獨立貢獻無法分離且為產業資助、小樣本。

L5 主流學會（Mayo 僅承認用於 manganese deficiency；Cleveland 僅 indirect 提到骨密度；Harvard 僅功能性 "helps form bones"；AAOS/BHOF/ACR 完全未提及錳作為骨折介入）一致無背書；L4 監管（FDA、EFSA、NHS、TFDA、WHO）僅以營養素 / 食品添加物身分核可，並無任何骨折相關 authorized claim，且 EFSA 2023 將成人 UL 下修至 3 mg/日反映安全餘裕極窄。
判 U（未驗證 / 證據空白）而非 D（反證據）—— 是「無證據」而非「證據顯示無效」。

Spinal bone loss in postmenopausal women supplemented with calcium and trace minerals
結論：Only the Ca + trace minerals combination arm significantly attenuated spinal bone loss vs placebo; the Ca-alone arm did not reach significance, and the trace-mineral-alone arm (Zn+Mn+Cu) showed numeric but non-significant attenuation. The trial cannot isolate the manganese contribution from zinc and copper, and fractures were not an endpoint. Frequently cited as the basis for adding manganese to bone formulas despite no isolated-manganese effect being demonstrated.

Trace elements in human nutrition: manganese
結論：Documented manganese deficiency in humans is extremely rare; experimental short-term depletion in metabolic-ward studies produced biochemical changes but no documented fractures. Animal data show manganese is required for proteoglycan and chondroitin sulfate synthesis in bone matrix, but no human RCT has tested isolated manganese supplementation on fracture outcomes.

The Role of Trace Elements and Minerals in Osteoporosis: A Review of Epidemiological and Laboratory Findings
結論：Authors conclude evidence for manganese as an isolated intervention for bone outcomes is sparse and limited to combination trials (notably Strause 1994) and observational serum/intake correlations. No included study used manganese alone, and no fracture-endpoint RCT for manganese was identified. Authors caution against extrapolating combination-arm benefits to single-mineral supplementation.

Relationship between blood manganese and bone mineral density and bone mineral content in adults: A population-based cross-sectional study
結論：Cross-sectional inverse U-shaped association reported between serum manganese and BMD in some subgroups, with both very low and very high serum manganese associated with lower BMD. The design cannot establish causality or supplementation effect, and fractures were not assessed.

You should be able to get all the manganese you need from your daily diet. Taking high doses of manganese for long periods of time might cause muscle pain, nerve damage and other symptoms, such as fatigue and depression. For most people, taking 4mg or less of manganese supplements a day is unlikely to cause any harm. For older people, who may be more sensitive to manganese, taking 0.5mg or less… 來源↗

Manganese is an essential trace element that is naturally present in many foods and available as a dietary supplement. Manganese is a cofactor for many enzymes, including manganese superoxide dismutase, arginase, and pyruvate carboxylase. Through the action of these enzymes, manganese is involved in amino acid, cholesterol, glucose, and carbohydrate metabolism; reactive oxygen species scavengin… 來源↗

PTT（e-shopping、MuscleBeach、Doctor-Info、regimen）、Dcard、Mobile01 幾乎沒有把「錳」單獨當作骨折癒合補充品的在地討論。骨折相關熱門文（如 e-shopping「骨折開刀後的營養品挑選」）社群焦點全集中在蛋白質、鈣、膠原蛋白與維生素D，整篇未提及錳。錳僅在「綜合礦物質」評比文與「海藻鈣含鎂鋅錳等70餘種微量元素」的行銷描述中被動列名，並非鄉民主動推薦或實測的補骨成分。屬冷門題目，無真實社群聲量，無相關品牌、劑量或副作用回饋。
💬社群實感
無共識（社群幾乎無人將錳作為骨折癒合或補骨補充品討論；骨折營養話題集中在蛋白質、鈣、膠原蛋白、維生素D）
