The Letter D Is for Dense Bones

Sep 01, 2005

A recent study in the May 11 issue of The Journal of the American Medical Association suggests that vitamin D in high doses may help sedentary older adults avoid certain types of bone fractures. After comparing study participants who received oral vitamin D supplements (with and without calcium supplementation) with those who were given either calcium alone or a placebo, the study authors reached this conclusion: “Oral vitamin D supplementation between 700 [and] 800 International Units (IU) per day appears to reduce the risk of hip and any nonvertebral fractures in ambulatory or institutionalized elderly persons. An oral vitamin D dose of 400 IU per day is not sufficient for fracture prevention.”
