Very interesting...

The book I had, which I think was called Secrets of Women's Health... but I'm too tired to go find it and look, said that you had to have magnesium with calcium... and I think that must be why so many calcium products have magnesium in them.

I always take a magnesium now whenever I have a food with calcium in it.

This has been working great, which I judge by the fact that when I had a bone density test, which the administrators appeared to be SURE would show I needed to use their drug, it showed that my bone density was REALLY good. The test administrators voiced surprise and of course congratulated me.

So that's why I always take magnesium with calcium now, and I try to avoid taking any calcium except in food.
