SAN FRANCISCO: Over 60s should take vitamin D supplements to ward off cognitive decline and dementia, scientists have advised, after a study showed those with deficiencies suffered rapid mental deterioration.
Known as the sunshine vitamin because the body produces it when in contact with sunlight, vitamin D is essential for promoting calcium absorption and bone health and some studies suggest it may protect against cancer, diabetes and multiple sclerosis.
But new research suggests it also plays an important role in mental health in later life.
Scientists found that over-60s with vitamin D deficiency declined mentally at a rate three times faster than those with adequate levels.
The researchers suggest that low vitamin D levels should now be considered a risk factor for dementia, particularly among people with darker skin tones.
