葡萄籽萃取 Grape Seed Extract × 高血壓
Grape seed proanthocyanidins show a small meta-analytic blood-pressure reduction, but the evidence base is genuinely inconsistent rather than merely modest.
Grape seed proanthocyanidins show a small meta-analytic blood-pressure reduction, but the evidence base is genuinely inconsistent rather than merely modest. The pivotal 2022 dose-response meta-analysis found systolic BP non-significant (WMD -3.55 mmHg, 95% CI crossing zero) with extreme heterogeneity (SBP I-squared 97.4%), directly conflicting with the older 2016 meta-analysis, and the proanthocyanidin meta-analysis rests on only 6 RCTs / 376 participants. Effects concentrate in younger, obese, and metabolic-syndrome subgroups rather than the general hypertensive population, and the underlying RCTs are small (n=29-36 completers) with notable attrition and largely undisclosed funding. EFSA rejected the MegaNatural-BP blood-pressure claim in 2021 for insufficient cause-and-effect substantiation, and no clinical institution (Mayo, Cleveland, Harvard) or society (AHA) addresses grape seed extract for hypertension at all. The outcome is also a surrogate (blood pressure) with no hard cardiovascular endpoint data, so the honest grade is C: weak, inconsistent evidence concentrated in subgroups, below Examine's B.

- apply_hec_rules — 高品質 SR/MA 顯示 positive (3 篇 > 0 negative)
- tier_strict_requirement_check — Tier 條件達標，未降階
- detect_disputes — 偵測到 0 個 hard + 1 個 soft dispute
- decide_status — 依 tier + dispute 結果決定 status
台灣社群（PTT regimen/美容版、Dcard 女孩/美妝版、Mobile01）對葡萄籽萃取討論量大，但幾乎全集中在美白護膚、抗氧化、經痛/婦科用途；針對「高血壓/降血壓」的真實鄉民實測心得近乎不存在。regimen 版相關文僅在問 Costco/iHerb 品牌與 OPC 劑量，未提血壓。
無共識（台灣社群幾無針對高血壓的真實使用心得；現有討論集中於美白/抗氧化/經痛）
- Dcard 女孩版有人反映吃 Swisse 葡萄籽錠後下體不正常出血，停用後改善
