Vitamin B may reduce risk of stroke
Posted by Neill Abayon
Researchers have uncovered evidence that suggests vitamin B supplements could help to reduce the risk of stroke, according to a study published in the journal Neurology.
Vitamin B supplements are said to be beneficial for many health issues, including stress, anxiety, depression, dementia, Alzheimer's disease and heart disease.
However, according to Xu Yuming of Zhengzhou University in Zhengzhou, China, previous studies have conflicting findings regarding the use of vitamin B supplements and stroke or heart attack.
"Some studies have even suggested that the supplements may increase the risk of these events," he adds.
In order to determine the role of vitamin B supplements in the risk of stroke, Prof. Yuming and colleagues analyzed 14 randomized clinical trials involving a total of 54,913 participants.
All studies compared use of vitamin B supplements with a placebo, or a very low dosage of the vitamin. All participants were then followed for a period of 6 months.
During this time, there were 2,471 reported strokes over all of the studies.
