Calcium, Vitamin D: not too much!

There was a recent news item on research which indicates that excess intake of calcium and vitamin D is linked to dementia in the elderly, due to an increase in brain lesions. This was research done by Dr. Martha Payne, from Duke University.

So if we don't get enough, our bones may break, and if we get too much we may get dementia. (Idle thought: since Ezorb is always boasting that their calcium is more easily absorbed than other forms of calcium, wouldn't that mean their calcium is more likely to cause dementia?)
