That's really interesting, Equinox. I wonder, too, if the form of calcium supplement matters--I suspect, yes.

Most calcium supplements come from seashells. Yeah, that's gotta be good for you! The ones I take come from seaweed, so could arguably be considered "food." That's one reason why I cut back, but not out, my supplements. I come from a long line of women who easily became osteoporotic as they aged.
