"It doesn't help fractures, which is what it was supposed to be. It's what I used to prescribe it all the time, giving calcium to menopausal women, for example. It doesn't prevent fractures, and there is increasing evidence that it's associated with heart disease."

This contradicts decades of medical advice promoting calcium supplementation for bone strength.
