If you’re referring to the viral headline, the vitamin most likely being discussed is vitamin E—but “raises stroke risk overnight” is an exaggeration.
High-dose vitamin E supplements can increase bleeding risk, and clinical trials have found an increased risk of hemorrhagic (bleeding) stroke in some groups taking supplemental vitamin E. The concern is mainly with supplements and higher doses, not vitamin E naturally present in foods. Office of Dietary Supplements+1
A few important points:
-
Vitamin E is an essential nutrient and is found in foods such as nuts, seeds, vegetable oils, and leafy greens.
-
The recommended intake for adults is about 15 mg/day.
-
High-dose supplements can interfere with blood clotting and may interact with warfarin and other anticoagulant or antiplatelet medicines. Office of Dietary Supplements
-
There is no evidence that taking a normal dietary amount suddenly causes a stroke overnight.
-
Don’t stop a prescribed supplement or medication solely because of this headline.
If you tell me which vitamin and dose the post claims is dangerous, I can check the specific claim and explain the actual risk.
