The Women’s Health Initiative reported reduced bone loss with treatment.

But do healthier bones mean older women will become more active?

First, the details.

• 33,067 older women were randomly assigned to take 1,000 mg calcium carbonate plus 400 IU vitamin D3 per day or matching placebo pills.
• Changes in physical functioning was based on responses to a questionnaire 1 year before starting the study and at the end (about 7 years later).
• The participants and researchers were not aware of the treatment given — double blind.

And, the results.

• There was no association between taking calcium/vitamin D and subsequent physical functioning or performance compared to taking placebo.

The bottom line?
So, taking calcium and vitamin D might protect bones, but it doesn’t guarantee that older women will become more active.

What’s that old saying about leading a horse to water?
