Two studies show that one particular vitamin is crucial to keep your brainpower from dimming as you grow older. Without this nutrient, your risk of Alzheimer’s climbs and your thinking abilities are more liable to slip.
Research in France demonstrates that consuming very little vitamin D is associated with a greater risk of developing Alzheimer’s disease. At the same time, scientists in Minneapolis have found that low vitamin D levels among older women are associated with higher odds of global cognitive impairment and a higher risk of global cognitive decline.
In the Minneapolis research, scientists found that very low levels of vitamin D (less than 10 nanograms per milliliter of blood serum) among older women were associated with higher odds of global cognitive impairment at the beginning of the study.
