麩醯胺酸 Glutamine × 運動後恢復

結論：證據分歧

L1 Examine 在運動恢復相關 primary clinical outcome（Muscle Damage、Muscle Mass、Power Output、Body Fat）一致給出 D（no effect, n=30-40），surrogate Ammonia/Uric Acid 僅 C 級且為 mixed effect；L2 PubMed 顯示 2019 Ahmadi MA（25 RCT 池化）結論 null，僅 Legault 2015（n=16）、basketball 2021（n=12）、triathletes 2023（n=9, 與 whey 併用）等極小樣本 crossover 呈現 CK/痠痛改善，整體屬「機轉合理、生化標記有訊號、功能性表現證據不一致」的 C tier。

The effect of glutamine supplementation on athletic performance, body composition, and immune function: A systematic review and a meta-analysis of clinical trials
PMID: 29784526 2019 統合分析
結論：Glutamine had a significant effect on weight reduction (WMD = -1.36, p=0.02) and neutrophil reduction at >200 mg/kg (p=0.03); glutamine dipeptide raised post-exercise blood glucose (p=0.002). Authors conclude glutamine has NO effect on athletic immune system, aerobic performance, or body composition overall.

The Influence of Oral L-Glutamine Supplementation on Muscle Strength Recovery and Soreness Following Unilateral Knee Extension Eccentric Exercise
PMID: 25811544 2015 RCT (double-blind) n = 16
結論：Glutamine produced greater relative peak torque at 180 deg/sec immediately post (71+/-8% vs 66+/-9%) and at 72h (91+/-8% vs 86+/-7%) post-exercise (all p<0.01); lower soreness at 24, 48, 72h (p<0.01). Effects greater in males. Small crossover (n=16).

Effect of Glutamine Supplementation on Muscular Damage Biomarkers in Professional Basketball Players
PMID: 34204359 2021 RCT (double-blind) n = 12
結論：Glutamine group showed significantly lower CK, AST, and myoglobin vs placebo, suggesting less exercise-induced muscle damage; lower ACTH and stable cortisol. Very small (n=12) crossover in a single team.

Effect of glutamine supplementation combined with resistance training in young adults
PMID: 11822473 2001 RCT (double-blind) n = 31
結論：Both groups increased 1RM squat ~30% and bench ~14%; no significant between-group difference in strength, lean mass, or protein degradation. Glutamine had NO effect on performance, body composition, or muscle protein breakdown in healthy young adults.

Hydrolyzed whey protein enriched with glutamine dipeptide attenuates skeletal muscle damage and improves physical exhaustion test performance in triathletes
PMID: 36685057 2023 RCT (double-blind) n = 9
結論：Combined MGln supplementation decreased plasma LDH and CK (indicating muscle-damage protection) and increased %VO2max, VT2 duration, and total exhaustion distance vs placebo. Confounded by co-supplementation with hydrolyzed whey; glutamine contribution not isolated. Very small (n=9 elite male triathletes).

📍立場總覽

台灣健身社群（PTT MuscleBeach／Fitness 板）對麩醯胺酸用於運動後恢復多持懷疑或無感態度，常被歸類在「食品類補充品近乎無效、吃心安」一群；鄉民公認真正值得買的是肌酸與乳清，麩醯胺酸與 BCAA、左旋肉鹼一起被視為性價比偏低。少數重訓量極大者認為對維持肌肉／恢復「也許有點幫助」，但無人提出明確實測成效，討論深度低。

💬社群實感

多數負面／無感（健身社群普遍認為對一般人運動後恢復無明顯感受，常被列為可省略的補充品；僅極少數高訓練量者認為或許有助維持肌肉）

破解迷思 社群最常見的 4 個誤解
✕
迷思把「防止肌肉分解」誤當成「促進增肌」
✓
事實麩醯胺酸主要是減緩肌肉流失而非增加合成，對想長肌肉的人幫助有限
✓
事實被「條件式必需胺基酸」分類與癌症／術後修復的行銷誤導，以為一般健身者也必須額外補充（飲食正常其實不缺）
✕
迷思誤以為能顯著提升免疫力、減少訓練後感冒、加速恢復
✓
事實運動訓練的整合分析顯示對免疫功能、最大攝氧量、身體組成幾乎無顯著改善
✓
事實以為單獨大量補充很安全、可長期高劑量服用（忽略有肝毒性個案警示）
🩹 社群通報的副作用
  • 高劑量長期單獨補充的肝毒性個案（腹痛、眼睛／皮膚泛黃、噁心）——屬醫療通報，非健身社群普遍反映
  • 健身社群本身對麩醯胺酸副作用回饋極少，多數人反映「無感」而非不適
