D is for “Don’t Bother”

More than 50 percent of adults—many of them right here in the sun-starved Northeast—take Vitamin D supplements to help keep their bones healthy as they age. But a new study suggests they might as well be popping a placebo.

Researchers at the University of Auckland in New Zealand looked at thousands of healthy adults, who took Vitamin D for a period of two years and found no evidence the practice increased bone density at the hip, forearm, spine or body as a whole.

The study did not look at the common practice of combining Calcium supplements with Vitamin D, but on its own, researchers concluded it doesn’t seem to make much difference in overall bone health.

The study appeared recently in the British medical journal Lancet.
