吡咯喹啉醌 (PQQ) Pyrroloquinoline Quinone (PQQ) × 疲勞

結論：證據分歧

獨立判讀為 U（未驗證）而非 D。

獨立判讀為 U（未驗證）而非 D。

Examine D 'No effect' 看似負面，但其底層證據僅為單一 n=17、開放標籤、無安慰劑、Mitsubishi Gas Chemical 相關、非 PubMed 收錄的 Nakano 2012 FFHD 試驗——該設計既無法證實效果也無法證實無效，是『資料極度不足』而非『已證實無效』。

L2 PubMed 確認：迄今**沒有任何以疲勞為主要終點、含安慰劑對照、樣本 ≥30 的人類 RCT**；兩篇雙盲 RCT（Itoh 2016 n=41、2024 MCI n=34）測的是認知不是疲勞，Hwang 2020 n=23 體能 RCT 顯示 PQQ 不改善有氧表現（對能量訴求的負面訊號）。

Mayo/Cleveland/Harvard/NIH ODS/NCCIH/MEAction/CDC/IACFS-ME/AAFP/AGS 全部沉默；FDA GRAS 與 EFSA Novel Food 皆僅為食品安全核可、不背書任何疲勞功效宣稱。

整體屬「機轉合理但人體疲勞 RCT 證據幾乎不存在」的典型 U 級情境。

Effects of Oral Supplementation with Pyrroloquinoline Quinone on Stress, Fatigue, and Sleep (Nakano, Yamamoto, Okamura, Tsuda, Kowatari) — Functional Foods in Health and Disease (not PubMed-indexed)

The effects of pyrroloquinoline quinone disodium salt on brain function and physiological processes (Yamada et al., J Med Invest, Tokushima)
PMID: 38735721 2024 系統性回顧
結論：Authors conclude PQQ supports memory, attention, sleep and mood, with stronger cognitive gains in younger participants and synergy with CoQ10. Fatigue is folded into mood/sleep discussion rather than treated as a primary endpoint; the only direct fatigue evidence cited is the Nakano 2012 open-label trial. Review is written by Mitsubishi Gas Chemical researchers and a Tokushima University collaborator — strong manufacturer perspective.

PMID: 38908296 2024 隨機對照試驗 n = 34
結論：Significant increase in serum BDNF (p=0.01), ADAS-Cog orientation domain (p=0.03), cerebral oxygenation 48.4 to 52.8 percent (p=0.005) and NAA at 7 of 13 brain locations (p<=0.05). Fatigue was NOT a measured endpoint; this trial speaks to cognition/mitochondrial biomarkers in MCI, not subjective fatigue. Relevance to general fatigue is mechanistic only.

結論：PQQ group showed smaller Stroop interference change and improved Touch M in the low-baseline subgroup; NIRS suggested increased prefrontal blood flow. No fatigue, sleep or mood endpoint reported. Industry COI: author M. Nakano is Mitsubishi Gas Chemical (BioPQQ manufacturer).

Effects of Pyrroloquinoline Quinone (PQQ) Supplementation on Aerobic Exercise Performance and Indices of Mitochondrial Biogenesis in Untrained Men (Hwang et al.)
PMID: 31860387 2020 隨機對照試驗 n = 23
結論：No significant between-group differences in aerobic performance or body composition (p>0.05). Both groups improved VO2peak and exercise duration with training (p<0.05). PGC-1alpha protein significantly higher in PQQ group (p<0.05). Authors conclude PQQ does NOT elicit ergogenic effects on aerobic performance — a directly relevant negative signal for the 'energy/anti-fatigue' marketing claim, even though subjective fatigue was not measured.

Pyrroloquinoline quinone protects against exercise-induced fatigue and oxidative damage via improving mitochondrial function in mice (Liu et al., FASEB J)
PMID: 33710654 2021 Other
結論：PQQ extended TTE, reduced serum CK and LDH, increased antioxidant enzyme activity, suppressed ROS and MDA, and preserved mitochondrial complex I (NADH dehydrogenase) function. Strong mechanistic support but mouse model only — does NOT translate to human fatigue without confirmatory human RCT.

📍立場總覽

PQQ 在台灣社群屬冷門小眾成分，PTT/Dcard/Mobile01 幾乎查無真實『PQQ 對疲勞』使用心得；BeautySalon/Mancare 保健品討論串多談魚油、B 群、瑪卡、鎂等而非 PQQ。相關內容幾乎全來自痞客邦業配、品牌行銷與健康媒體（heho/苼莛/SK22 代購）等抗老/線粒體話術，社群真實討論訊號極弱。

💬社群實感

無共識（台灣社群幾乎無真實 PQQ 抗疲勞使用心得，討論量過低無法判斷）

破解迷思 社群最常見的 3 個誤解
✓
事實把細胞/動物實驗的『促進線粒體生成』直接等同於『人吃了就會抗疲勞、變有精神』（人體臨床證據僅 1 篇 17 人小型試驗，極為有限）
✓
事實宣稱抗氧化力是維生素 C 的 7.4 倍即代表抗疲勞效果更強（抗氧化力數據與臨床抗疲勞療效是兩回事）
✓
事實把 PQQ 當『長壽維生素／抗老神藥』（多為品牌與痞客邦業配話術，非實證定位）
