Dementia study questions advice on taking supplements
Taking vitamin B12 and folic acid supplements does not seem to cut the risk of developing dementia, say Dutch researchers.
This contradicts what has previously been suggested, they say.
In one of the largest studies to date, there was no difference in memory test scores between those who had taken the supplements for two years and those who were given a placebo.
The research was published in the journal Neurology.
B vitamins have been linked to Alzheimer's for some years, and scientists know that higher levels of a body chemical called homocysteine can raise the risk of both strokes and dementia.
Vitamin B12 and folic acid are both known to lower levels of homocysteine.
