Vitamin E supplements have been linked to an increased risk of hemorrhagic stroke in a new meta-analysis. Taking vitamin E long-term in doses of 300-800 IU daily - including either natural or synthetic forms - does not affect total stroke risk. However, it significantly increases the risk of cerebral hemorrhage by 22%. In contrast, the analysis also found that vitamin E reduces the risk of ischemic stroke by 10%, i.e. a stroke due to a blood clot in the brain. This means that taking vitamin E could prevent 21 ischemic strokes for every 10,000 patients treated for at least one year...but could cause 8 hemorrhagic strokes. Because vitamin E supplements, while preventing one kind of stroke, increases the risk of another kind of stroke, you are advised not to take high-dose vitamin E long-term. Most people get adequate intake from their diet. By consuming nuts, seeds and vegetables, you will get adequate vitamin E. According to Ayurveda, Vitamin E rich foods such as almonds and sunflower oil should be consumed on a regular basis.
