Older adults with deficiencies in vitamin D experience more rapid cognitive decline over time than those with adequate vitamin D levels.
In a study published Sept. 15 in JAMA-Neurology, Joshua Miller, professor of nutritional sciences at the Rutgers School of Environmental and Biological Sciences, found that people with low levels of vitamin D experienced rates of cognitive decline at a much faster pace than people with adequate vitamin D status.

“There were some people in the study who had low vitamin D who didn’t decline at all and some people with adequate vitamin D who declined quickly,” said Miller. “But on average, people with low vitamin D declined two to three times as fast as those with adequate vitamin D.”
