Vitamin E supplementation and cardiovascular events in high-risk patients (HOPE trial)
PMID: 10639540 2000 RCT (double-blind) n = 9,541
結論：In high-risk patients (with vascular disease or diabetes), vitamin E 400 IU/day for a mean 4.5 years had no effect on the primary composite cardiovascular endpoint (16.2% vs 15.5%, RR 1.05, 95% CI 0.95-1.16, P=0.33); no benefit on MI, stroke, or CV death individually.

Effects of long-term vitamin E supplementation on cardiovascular events and cancer: a randomized controlled trial (HOPE-TOO extension)
PMID: 15769967 2005 RCT (double-blind) n = 7,030
結論：Long-term Vitamin E did NOT prevent cancer or major cardiovascular events. HARM SIGNAL: heart failure increased in Vit E group (RR 1.13, 95% CI 1.01-1.26, P=0.03) and hospitalization for heart failure also increased (RR 1.21, 95% CI 1.00-1.47, P=0.045). Authors concluded long-term Vit E may increase heart failure risk in patients with vascular disease or diabetes.

Dietary supplementation with n-3 polyunsaturated fatty acids and vitamin E after myocardial infarction: results of the GISSI-Prevenzione trial
PMID: 10465168 1999 RCT (open-label) n = 11,324
結論：Over 3.5 years in post-MI patients, vitamin E 300 mg/day showed NO significant benefit on the primary endpoint (RR 0.86 by 4-way analysis, NS) — explicitly stated 'vitamin E had no benefit'; the n-3 PUFA arm reduced events but the Vit E arm did not.

The effect of vitamin E and beta carotene on the incidence of lung cancer and other cancers in male smokers (ATBC Cancer Prevention Study)
PMID: 8127329 1994 RCT (double-blind) n = 29,133
結論：Alpha-tocopherol did not reduce lung cancer or major cardiovascular events. HARM SIGNAL: more deaths from hemorrhagic stroke in the Vit E arm; beta-carotene arm showed increased lung cancer and overall mortality. Established the negative landmark for Vit E in smokers.

PMID: 10634823 2000 隨機對照試驗 n = 28,519
結論：Over median 6 years in 28,519 male smokers, alpha-tocopherol modestly reduced cerebral infarction (~14%) but markedly INCREASED fatal subarachnoid hemorrhage by 181% (95% CI 37%-479%, P=0.01) and overall subarachnoid hemorrhage ~50%. Net effect on stroke was unfavorable in this population — landmark hemorrhagic stroke harm signal for Vit E.

Vitamins E and C in the prevention of cardiovascular disease in men: the Physicians' Health Study II randomized controlled trial (Sesso et al.)
PMID: 18997197 2008 RCT (double-blind) n = 14,641
結論：Over mean 8 years, neither Vit E nor Vit C reduced major cardiovascular events, total MI, total stroke, or CV mortality. Vit E was associated with INCREASED hemorrhagic stroke (HR 1.74, 95% CI 1.04-2.91, P=0.04). The U.S. landmark primary-prevention RCT confirming no Vit E benefit.

Antioxidant supplements for prevention of mortality in healthy participants and patients with various diseases (Bjelakovic Cochrane review)
PMID: 22419320 2012 Cochrane SR n = 296,707
結論：Pooled 78 RCTs (n=296,707): in low-risk-of-bias trials, Vit E significantly increased all-cause mortality (RR 1.03, 95% CI 1.00-1.05); 12.0% deaths in Vit E vs 10.3% controls. Authors concluded beta-carotene and Vitamin E 'seem to increase mortality.' No cardiovascular benefit demonstrated; signal of harm.

You should be able to get all the vitamin E you need from your diet. Taking 540mg (800 IU) or less a day of vitamin E supplements is unlikely to cause any harm. If you take vitamin E supplements, do not take too much as this could be harmful. 來源↗

社群對維生素E護心討論稀疏，多作魚油/綜合維他命的搭配配角；主流訊號是警告高劑量出血與中風風險，普遍認為高劑量補充無助預防心臟病。

💬社群實感

無共識（討論稀疏，多視為魚油/綜合維他命配角，少有單獨護心實測心得）

破解迷思 社群最常見的 3 個誤解
✓
事實維生素E能促進血液循環、保護心血管，所以吃越多越好（錯誤，高劑量反增出血性中風風險且無助預防心臟病）
✓
事實維生素E與C搭配可調節血壓、治療心血管疾病（誇大，缺乏臨床證據支持）
✓
事實脂溶性沒差、天天高劑量補沒問題（錯誤，會蓄積體內造成危害）
🩹 社群通報的副作用
