From the Back Cover

Are you taking calcium or vitamin D? This book could save your life!

Learn the secret to avoiding osteoporosis and heart disease.

Millions of people take vitamin D and calcium supplements for bone health. New research shows that this actually increases the risk of heart attack and stroke because the added calcium builds up in arteries—the calcium paradox. The secret to keeping bones strong and arteries clear is vitamin K2, a little-known supernutrient that humans once thrived on and that has been ignored by scientists for almost 70 years.

Inside this book, you'll find:

  • How consumption of grass-fed animals traditionally provided us with ample quantities of vitamin K2—while grain-based animal feed contributed to the eradication of vitamin K2 in our modern diet

  • How K2 is the most important anti-aging nutrient for fighting wrinkles, Alzheimer's, heart disease, osteoporosis and more

  • The health benefits K2 promotes for straight, cavity-free teeth and strong bones in children

  • Which delicious "sinful" foods are brimming with heart-healthy K2

  • Ways you can safely get the most benefit from your calcium and vitamin D supplements

Also available as an e-book through online retailers.

I want to emphasize that this book is fantastic -- for the most part. Everyone needs to know about vitamin K2. This book is eye opening for many, many reasons. Please get it and read it.

However, if you go beyond food souces, her advice on supplement choices seems to gloss over, and perhaps even mislead, with some of the facts in regard to her recommendation for the MK-7 version of vitamin K2 instead of the MK-4 version.

Her main criticism of MK-4 is the that it is `synthetic.' That `synthetic' word is a red flag for many, myself included. However, all the supplements are made in a factory/laboratory. The MK-4 is still made with natural occurring ingredients, just like the MK-7.

But even more important, which one is really going to work for you!

My personal experience:
I have yet to hear from anyone that the MK-7 supplements will dissolve the calcified plaque that forms behind the lower front teeth. In 2 days, the Thorne MK-4 supplement completely removed the krud behind my teeth. I was amazed by this. Ever since, I don't need a teeth cleaning at the dentist. I had been taking the Jarrow MK-7 for more than a year without this dramatic effect.

This proves to me that this supplement is taking calcium away from someplace it's not supposed to be and, hopefully, putting it someplace that it IS supposed to be. Which is the major idea presented in this book.

I switched to the MK-4 as an experiment after reading Richard Nikolay's post on Free the Animal blog where he was surprised to notice this same teeth cleaning effect. And I had read about it along time ago in the Track Your Plaque blog of Dr. William Davis.

Why does this author emphasize that MK-7 is better than MK-4?

Please read the studies directly.

Beware: taking calcium and/or vitamin D can kill you if you don't also supplement with K2!

This excellent book explained why more than 6 months of taking 10,000iu daily of vitamin D3 did nothing for me, even though I live way north of the 40th parallel (most people above that are deficient and, the further north, the more deficient we are). Calcium needs vitamin D3 and both need vitamin K2 (the author recommends K2 in the form of menaquinone-7 or MK-7 but apparently there is research indicating MK-4 is better)!
[later note: I did have problems with MK7. Thanks to warnings from two kind Amazon readers in the comments section about MK7 affecting the heart I switched to MK4. I had been wondering why my atrial fibrillations had worsened again recently - there are several kinds of af, mine feels like heart shivers, essentially the top half of the heart sometimes shudders like a jelly because it is not pumping in time with the lower half. I was despairing about the worsening because the af had finally started to get better - within a month of starting the combined treatment of my adrenal fatigue and low thyroid (undiagnosed for 20 years! PLEASE read Stop The Thyroid Madness if you suspect problems with either or both yourself). I just hadn't realized that the MK4 - which I had only started taking just a few weeks ago - was the reason! I stopped the MK4 as well, and my af reduced substantially within 24 hours of stopping the MK4. Perhaps anyone with heart issues should avoid K2 - or perhaps it's because I don't need to supplement with K2 because I eat mainly organic ("grass-fed") meat products, which provide K2, unlike commercially farmed meats?]

I read eight (yes 8) books on vitamin D3, most of them well researched, yet none of them explained this.

This book is very well written. It is clear, well organized, and referenced throughly in the back of the book for each chapter. It is written at about the level of Scientific American, easy enough for the intelligent layman to understand. It has particular relevance to anyone on a vegan diet, since most vegans do not eat the only vegan source of Vitamin K2, namely natto (fermented soybeans). For meat eaters, it explains very well the benefits of eating grass fed beef, because vitamin K2 is made in the steer's stomach from the grass.

The blood test for K2 deficiency is indirect, in that it measures the amount of osteocalcin (a protein activated by Vit. K2) that has not be carboxylated (activated). It is called the ucOC test (undercarboxylated osteocalcin) test is not readily available. When it does become available it is very likely that vegans and many meat eaters will be found to be deficient in this vitamin and will suffer the long term consequences, if they do not supplement. One possible consequence of insufficient K2 is stenosis of the aortic valve with calcium. Jack LaLanne had an operation for correction of a stenosed aortic valve (he was a vegan most of his life), and he died shortly thereafter from pneumonia in his weakened condition. Vitamin K2 supplementation might have allowed him to live well past 100.

After being diagnosed with severe osteoporosis at the tender age of 32, I started popping all forms of supplements and supplement formulas with Ca, Mg, Zn, Boron, Vitamin D galore, special clays, herbal formulas--supposedly the best of the best, spending THOUSANDS of dollars on supplements over the past 7 years, and my last bone scan showed ZERO improvement, and in fact that they were even a bit WORSE! After hearing a radio interview with the author, Dr. Kate Reaume-Bleue, I decided to buy her book and it is probably the best investment I've made in all of the past 7 years! THIS is what I am lacking! Without Vitamin K2, you CAN'T build new bone. It's physiologically and biochemically impossible, and Dr. Kate explains why in very easy-to-understand language, yet gives you the science and biochemistry to back it all up. She also goes into the OTHER fat-soluble vitamins (A,D, and E) and why THEY are essential co-factors as well! The book is just packed with incredible, life-saving information for not only people suffering from osteoporosis, but heart disease, arthritis, diabetes, kidney stones, and a whole lot more! Because of the decimation of our food supply by big Agra and factory farming, we no longer get the K2 in our diet, and it is probably the most important nutrient that no one is talking about! PLEASE! Read this book, and then pass it on!
