“As a Brain Doctor, I’m Shocked: This Common Vitamin Could Raise Stroke Concerns for Seniors”
This headline is more alarming than the evidence supports. The vitamin most plausibly being referred to is vitamin E, but that doesn’t mean vitamin E routinely causes strokes in older adults.
What is the concern with vitamin E?
Some research has suggested that high-dose vitamin E supplementation may increase the risk of hemorrhagic (bleeding) stroke. An earlier meta-analysis of randomized trials found a 22% relative increase in hemorrhagic stroke, although it also found a small reduction in ischemic stroke. PubMed+1
However, later evidence has been less definitive. A larger systematic review of 18 randomized trials found no statistically significant increase in hemorrhagic stroke, concluding that the evidence was insufficient to establish that vitamin E supplementation causes this type of stroke. PubMed+1
A more recent 2023 meta-analysis likewise concluded that vitamin E supplements should not be used for stroke prevention, but it did not establish that ordinary vitamin E intake causes strokes. PubMed
Who should be particularly cautious?
Extra caution makes sense with high-dose vitamin E supplements, especially if someone:
- Takes anticoagulants or antiplatelet medicines
- Has a bleeding disorder
- Has previously had a hemorrhagic stroke
- Is taking several supplements that may affect bleeding
- Is considering large doses without a documented medical reason
Eating vitamin-E-containing foods such as nuts, seeds, vegetable oils, and leafy greens is very different from taking concentrated supplements.
What about seniors?
Being over 65 or 70 doesn’t mean you need to stop vitamin E. The important distinction is between normal dietary intake and unnecessary high-dose supplementation.
And there’s no good reason to replace proven stroke prevention with vitamins. For older adults, controlling blood pressure, cholesterol, diabetes, smoking, atrial fibrillation, and other cardiovascular risk factors is far more important.
Bottom line: The claim that a common vitamin suddenly “raises stroke risk” is an oversimplification. High-dose vitamin E supplementation has raised legitimate concerns about bleeding stroke, but the overall evidence is mixed and does not show that ordinary dietary vitamin E causes strokes. PubMed+1
If you’re taking a specific vitamin E product, tell me the dose (for example, 100 IU, 400 IU, or 1,000 IU) and any blood-thinning medicines you’re taking, and I can explain the concern more specifically.
