Vitamin D may not protect against memory loss

Past research has suggested that Vitamin D might protect against memory loss and decline in the aging brain.
Syracuse (WSYR-TV) -- Past research has suggested that Vitamin D might protect against memory loss and decline in the aging brain.

A study in The Journal of the American Geriatrics Society looked at 2,000 women whose average age was 71. They took 400 international units of Vitamin D, along with 1,000 milligrams of calcium every day for an average of eight years. The women developed cognitive impairments, everything from memory trouble to serious dementia – at the same rate as a comparison group given placebo pills.

Yet, the authors say they learned how calcium and Vitamin D might have conflicting effects and that points researchers toward a more definitive study, testing higher levels of Vitamin D alone. Many experts already recommend much higher doses of Vitamin D.
