B vitamins 'slow mental decline'

Friday, 16 December 2011 11:45 AM

Supplements are an ideal way to bridge the gap of nutrition likes and dislikes to ensure you get a well-rounded healthy diet. New research shows B vitamins slow mental decline in older people with symptoms of mild cognitive impairment.

More than 250 participants were randomly assigned to receive either a daily dose of B vitamins or a placebo and assessed over a two-year period.

B vitamins, such as folic acid, are known to reduce blood levels of homocysteine, a blood protein that may increase the risk of Alzheimer’s disease. The study also found those on B vitamins were better at everyday mental tasks, such as recalling information.

Dr Carrie Ruxton of the Health Supplements Information Service said: “Given that 16% of people over 70 years old have mild cognitive impairment and half of these go on to develop Alzheimer's disease, the findings from these two reports should be of interest to clinicians.

“In addition, with so many people, especially the elderly, failing to meet their daily nutrient needs from diet alone, it is worth recommending the use of a B vitamin supplement or a multivitamin containing B vitamins.”
