The problem I have with an announcement like this is that it is generally recognized that most folks are actually deficient in calcium.

We used to drimk well water and water flowing in streams, in most places in the country, positively loaded with calcium.
Now, in a lot of areas, we are drinking water that has far less than it used to.

Remember, if you fractionalize the body into elements, besides for carbon and water, calcium is by far the most prevalent element.

I wonder who funded the study and what form of vitamin D they were using.

Supported by the National Heart, Lung, and Blood Institute and the General Clinical Research Center program of the National Center for Research Resources, Department of Health and Human Services. The active study drug and placebo were supplied by GlaxoSmithKline Consumer Healthcare (Pittsburgh).

Methods We recruited 36,282 postmenopausal women, 50 to 79 years of age, who were already enrolled in a Women's Health Initiative (WHI) clinical trial. We randomly assigned participants to receive 1000 mg of elemental calcium as calcium carbonate with 400 IU of vitamin D3 daily or placebo. Fractures were ascertained for an average follow-up period of 7.0 years. Bone density was measured at three WHI centers.

Good Q and also, what form of calcium was used for the study. Many common forms used in supplements is anot al that easily assimilated, and thats what counts, by the body. Cal carbonate is most common - and is very hard for the body to assimilate. D helps with its use by the body, but still only a small % is actually going into the bloodstream.
Calcium citrate is probably the best form for humans. It should be accompanied by Vit D, and some Zinc for best use by the human system...;-)!
