Vitamin K2 the new Vitamin D?

Currently am reading a very interesting and important book (it seems) called 'Vitamin K2 and the Calcium Paradox.' It is one of those books that you can summarize in a few sentences but takes a book to adequately explain. This is the message that I have gotten out of the book so far: taking Calcium supplements can actually be dangerous if you do not also get enough vitamin K2 in your diet. Without sufficient K2 the calcium you are taking not only does NOT get deposited in your bones, but rather it ends up as plaque in your arteries and causes heart disease and possibly early death. If it's all true it should be a wakeup call for the millions (mainly women) who take calcium supplements. It could explain the increased prevalence of heart disease in women. I will blog more about this book later.
