For the first time, a study revealed that B vitamins are safe but would not protect those who suffered a stroke, of a heart attack or a stroke back.
Vitamin B doesn’t help to prevent strokes. The study looked at more than 8,000 people who’d already had a stroke, half of whom were given supplements containing vitamin B6, B12, and B9 (also known as folic acid). The other half were given inactive, placebo pills. After around three years, the supplements had made no clear difference to people’s likelihood of having a stroke or a heart attack.
Overall, 16.9 percent of people taking a placebo had a stroke or heart attack. This compared with 15.1 percent of people taking the vitamins. Although slightly fewer people taking the vitamins had a stroke, statistical tests show the difference is small enough to be down to chance, rather than an effect of the treatment. The vitamin pills didn’t cause any side effects, according to the study.
The study was published in The Lancet Neurology, which is owned by a company called Elsevier. Funding came from several organisations, including the Australian National Health and Medical Research Council and the UK Medical Research Council.
