D is for density as in bone density – a statistic that many women are concerned with. Bone density is a measure of the quantity of bone, not the quality. I like to make a distinction here, because bone quality is an important concern that is being overlooked by many.
Bone quality concerns reduced risk of fracture which should be distinguished from bone quantity as expressed as bone density. The conventional way to deal with osteoporosis is to keep old bone from being torn down by using estrogen and prescription drugs such as Fosamax and Actonel along with calcium and vitamin D supplements. .
The problem with this approach is that bone is living tissue. It is constantly being built up and torn down. The modern approach just works at keeping old bone from being torn down and using just calcium which does not greatly strengthen bone such that it resists mechanical stresses. The result may be increased bone density, but the quality of the bone is poor and tends to be brittle.
Calcium alone does not build strong bone. Read more

Bone Density: Quality over Quantity
When it comes to reducing the risky of fracture, bone quality is more important than bone quantity, says Margaret Durst, and to get quality, you need more than calcium.
