印度人參 Ashwagandha × 運動表現
結論：證據支持但有警示
L2 PubMed 三篇 SR/meta-analysis（含 2021 Bayesian meta、2020 VO2max meta、2025 overview）一致顯示印度人參對肌力、VO2max 與恢復有正向效益，JISSN 之 KSM-66 600 mg/日 RCT 亦支持，屬中等強度證據。

L2 PubMed 三篇 SR/meta-analysis（含 2021 Bayesian meta、2020 VO2max meta、2025 overview）一致顯示印度人參對肌力、VO2max 與恢復有正向效益，JISSN 之 KSM-66 600 mg/日 RCT 亦支持，屬中等強度證據。
但 Examine.com 自述「modestly enhance...more research is needed」、NIH NCCIH 與 Cleveland Clinic 明確指出「not enough evidence」、ACSM/ISSN 無官方立場聲明，且有效劑量（600-1000 mg/日）顯著高於台灣 TFDA 法定上限（250 mg/日），故給予 B（moderate）而非 A。

台灣健身社群對南非醉茄的態度偏向「半信半疑、可以一試」：少數人回報睡眠變好、白天情緒穩定，但多數重訓族認為對純粹力量／肌肥大幫助不明顯，常被列為非核心補劑，部分使用者反映晨間嗜睡或勃起反應較強等副作用。
💬社群實感
意見分歧
破解迷思 社群最常見的 5 個誤解
✓
事實誤以為南非醉茄能直接增肌、取代乳清或肌酸
✓
事實誤以為「印度人參」與台灣人參／高麗參同類，吃法可互換
✓
事實誤以為劑量越高越有效，忽略台灣 250mg/day 上限
✓
事實誤以為短期吃幾天就能感受到力量或運動表現提升
✓
事實把「降皮質醇」直接等同於「長肌肉」，忽略訓練與飲食才是主因
🩹 社群通報的副作用
- 白天嗜睡、頭昏
- 晨間勃起反應較明顯（影響日常作息）
- 腸胃不適、輕微噁心
- 與安眠／鎮靜類藥物併用過度放鬆
- 甲狀腺指數變動（少數案例）
