Calcium, Vitamin D Supplements Won't Prevent Fractures, Study Finds
In a new statement, the U.S. Preventive Services Task Force says there's not enough evidence that vitamin D and calcium supplements help healthy adults avoid fractures.

MONDAY, Feb. 25, 2013 — Adults without a history of bone fractures or osteoporosis should not take calcium and vitamin D supplements to reduce their risk of future fractures, members of the U.S. Preventive Services Task Force write in theAnnals of Internal Medicine.
There's simply not enough evidence to support supplement use — specifically, vitamin D supplements with greater than 400 IU or calcium supplements with greater than 1000 mg of calcium. Plus, calcium supplements can have their own set of risks, such as kidney stones, says Linda Baumann, a professor of nursing at the University of Wisconsin, Madison, who worked on the recommendations.
"After looking at the evidence, there isn't enough that shows that we can prevent fractures from occurring in healthy adults to recommend vitamin D and calcium supplements," Baumann says. "Although kidney stones are not a life-threatening risk, they are a risk or harm associated with a treatment that doesn't have evidence to show it works."
Surveys estimate that 56 percent of women over 60 take supplemental vitamin D, and 60 percent take a supplement containing calcium, the task force writes. But there's no shown benefit from either supplement in healthy pre- and postmenopausal women or men. But Baumann says these supplements might help people with a vitamin D deficiency, osteoporosis, or a history of fractures. She also notes that supplementation can reduce the risk of falling in older people who have previously suffered from falls.
Recent research has also associated calcium supplementation with heart attacks and even a higher all-cause death risk, though none of the studies reviewed for this recommendation found increased heart risks.
The task force based their recommendation on two systematic evidence reviews and a meta-analysis of vitamin D supplement use with or without calcium. More recent data from the Women’s Health Initiative also are consistent with inconclusive findings, except among a small group of long-term supplement users who experienced a lessened risk for hip — but not total — fractures. Instead of supplementation, the task force recommends screening for osteoporosis in women aged 65 years or older and in younger women who have an elevated fracture risk.
Marion Nestle, MPH, PhD, and Malden C. Nesheim, PhD, write in an accompanying editorial that they hope this recommendation will give clinicians pause before they prescribe vitamin D and calcium supplements to their patients. They also call for a recommendation for or against vitamin D and calcium supplements that considers all the potential health risks and benefits.
