If you’re fact
-checking that headline, be very skeptical. The claim that a vitamin suddenly “raises stroke risk overnight” is not supported by good evidence.
There isn’t a vitamin that is known to cause a dramatic stroke-risk increase after taking a normal recommended dose overnight. Stroke risk is influenced much more by factors such as high blood pressure, atrial fibrillation, smoking, diabetes, high cholesterol, and previous vascular disease.
One important nuance: supplements can cause harm when taken in excessive doses or in the wrong circumstances, and some supplements can interact with medications. That doesn’t mean the vitamin itself suddenly causes strokes.
If you tell me which vitamin the headline is referring to (for example, vitamin B12, D, E, or a multivitamin), I can explain what the actual evidence says and whether seniors should be concerned.
