something that you may also want to read is the Miracle of Magnesium--by Dr. Carolyn Dean--she is a naturopath/homeopath from here in Canada. I knew her many years ago, and she's *good.*
I still believe it's important that nothing be isolated and viewed as *the* thing...that said, maybe the pendulum can afford to swing -in general- from calcium (in exclusion) toward magnesium...
