Jakarta, vitamin E had always been known as an antioxidant that can fight disease, free radicals and helps normal human reproduction. But you should not carelessly take supplements of vitamin E because it can increase the risk of stroke.Researchers at Harvard Medical School, Boston, and INSERM in Paris have found that vitamin E supplements can increase the risk of some types of stroke.
Haemorrhagic stroke (bleeding strokes) is the most rare type of stroke and occurs when the arteries that supply blood to the brain ruptures, causing brain damage. Researchers found that vitamin E increases the risk of this stroke by 22 percent.
But the study also found that vitamin E was able to reduce the risk of ischemic stroke, the most common type of stroke, by 10 percent.
"However, supplements of vitamin E is only slightly reduce the risk of ischemic stroke and the results are generally even greater increased risk of haemorrhagic stroke. So we suggest to be careful and not carelessly take vitamin E," explained Dr Peter Coleman, deputy research director of The Stroke Association, BBC News reported on Saturday (6/11/2010).
Dr. Coleman has warned that people should still maintain a healthy lifestyle and maintain blood pressure and cholesterol. It has a much greater effect in cutting the risk of ischemic stroke than having to take supplements of vitamin E.
"This is a very interesting study, which showed that the risk of haemorrhagic stroke can be slightly increased by high levels of vitamin E supplements taken," explains Dr. Coleman.
Dr. Coleman also said that more research is needed to discover the mechanism of action and the safe limit of vitamin E.
"We urge people to maintain lifestyle with a balanced diet, regular exercise and monitoring their blood pressure to reduce the risk of stroke. But it would be very interesting to see further research in this study. Of course, people also should not be carelessly taking vitamin E supplements," he concluded .
