綠茶萃取 Green Tea Extract × 心血管疾病
Multiple RCT meta-analyses (PMID 36704803, n=4874 across 55 RCTs; PMID 24675010, n=1536) consistently show that green tea supplementation produces small but statistically robust improvements in surrogate markers - total cholesterol falls roughly 7.
Multiple RCT meta-analyses (PMID 36704803, n=4874 across 55 RCTs; PMID 24675010, n=1536) consistently show that green tea supplementation produces small but statistically robust improvements in surrogate markers - total cholesterol falls roughly 7.6 mg/dL, LDL-C roughly 5.8 mg/dL, and diastolic blood pressure roughly 1 mmHg - which justifies a real signal but only on biomarkers. Crucially, there are NO RCTs of green tea EXTRACT against hard cardiovascular outcomes (MI, stroke, CV mortality); the only hard-outcome benefit (CVD mortality RR ~0.86) comes from observational cohorts of green tea DRINKERS and is subject to residual confounding. Examine's own table confirms every B-grade outcome is a surrogate with no primary clinical CVD endpoint, and a small null RCT (PMID 22144918) tempers extrapolation from the surrogate meta-analyses. Every consulted clinic source (Mayo, Cleveland Clinic, Harvard) explicitly states the benefit is in the beverage, not concentrated extract capsules, and warns about hepatotoxicity; the AHA and ACC make no guideline recommendation. Given a genuine but small surrogate effect, absent extract hard-outcome data, the drinking-vs-extract gap, and a documented hepatotoxicity overhang, the honest extract-supplement grade is C rather than Examine's surrogate-driven B.
評分透明度
所有分數由 7 層證據引擎計算,過程公開可查▸查看完整決策路徑(audit trail)
- compute_raw_score — 加權公式: L2×0.30 + L3×0.25 + L5×0.25 + L11×0.10 + L1×0.10 = 0.448
- tier_from_score — 依分數區間映射至 tier letter
- apply_hec_rules — 高品質 SR/MA 顯示 positive (1 篇 > 0 negative)
- tier_strict_requirement_check — Tier 條件達標,未降階
- detect_disputes — 偵測到 0 個 hard + 0 個 soft dispute
- decide_status — 依 tier + dispute 結果決定 status
社群熱議度高但多繞著減脂代謝與降膽固醇,少有真正『為心血管病吃』的第一手心得;副作用反映集中在心悸與傷肝疑慮,業配評比文密集。
無共識(社群討論多集中於減脂/代謝與降膽固醇,極少有直接針對心血管疾病的第一手實測心得,心血管效益多來自部落格/媒體/廠商論述而非鄉民親身經驗)
- 心悸/心跳加快(咖啡因)
- 失眠、精神緊張
- 腸胃不適/刮胃
- 頭痛、噁心
- 肝指數異常(高劑量膠囊、空腹之肝毒性個案疑慮)
