From the Back Cover
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.

It is the best of the current crop of books popularizing K2. The only problem with her work is that she is Canadian so has limited experience with MK-4 in her practice (due to nanny-state potency restrictions there). It is absolutely not correct that MK-4 and MK-7 have the same effect and that dosage is the only difference. Pretty much all independent researchers acknowledge that if you could only take one, MK-4 is superior in most respects.
The primary people who advocate MK-7 exclusively over MK-4 are the Dutch researchers on the payroll, directly or indirectly via sponsored research, of the big MK-7 producers and then the main benefit they point out is the longer half-life (not really a benefit if you know what serum half-life means). Even the Japanese prefer MK-4 for high-dose therapeutic uses. All you have to do is go to PubMed and start reading some of the abstracts or do a web search on mk4 vs mk7 to get a broader and more informed perspective.
The MK-7 manufacturer sponsored research seems always careful to not directly compare with MK-4 (no non-inferiority trials). If they did we would discover that MK-7 is not found in the brain or the saliva, MK-4 is and it is neuroprotective. MK-7 does not cross the placenta and is not at significant amounts in breast milk. MK-4 is carried by HDL (which accounts for its more rapid clearing), whereas MK-7 is carried by VLDL (which causes it to linger in the blood instead of being picked up by the tissues). MK-4 is the body's preferred form from the time of the origin of the human species. Natto with MK-7 has only been a significant part of anyone's diet for maybe a millennium. If it needs to, the human body will transform available K1 into MK-4 (granted, not very effectively) not MK-7.
You wouldn't guess it by the way it is marketed, but even the fermented derived form of MK-7 is about as far from natto as you can get. One of the leading manufacturers, NattoPharma, doesn't even use the same bacteria as is used in natto (bacillus subtilis natto) and they claim there is zero soy in their product. The medium is chickpea (garbanzo bean) flour and dextrin and you can look up on Wikipedia the bacillus licheniformis they use for a culture bacteria. I suppose it does not really matter the source as long as the end product provides the stated potency.
Even more interesting is the fact that their newest product is actually synthetic MK-7 which is much cheaper to produce. Nothing wrong with that. It is a purer product than their naturally derived one. They even named it MenaQ7 PURE. Both of their products strip out the naturally occurring cis-isomer form of MK-7. Nothing wrong with that, either. The isolated trans-isomer form is what is wanted anyway.
The point to take away is that people get a warm fuzzy when they see the word natural associated with MK-7. Commercial naturally derived MK-7 (specifically MenaQ7) is far removed from nature and has nothing to do with natto. The company even says their synthetic version is bio-equivalent and nature-identical to their fermented version (i.e., you can't tell the difference). Soon, if not already, most all MK-7 on the market will be synthetic because it is purer and cheaper to make. [...] (I suspect Amazon will zap this link so I will also put it in the comments.)
Even the lovely Kate couldn't resist the financial lure of becoming a paid spokesperson for an MK-7 marketer (the vitamin company she works for). That only slightly detracts from her excellent book and she would have had to become a smuggler to become personally familiar with MK-4 in her practice anyway. But as always, when it comes to the validity of advice, always follow the money. There are good things to be said for MK-7 (I take it myself) but it is disingenuous to suggest it is somehow superior overall on its own to MK-4. The evidence does not support that view. They both have related and differing effects. It probably does make sense to take both.
The real problem is that well-heeled marketing and patent collection oriented companies that manufacture MK-7 use research funds as a means of marketing their specific products via carefully structured and relentless research programs. The end user requires much diligence to wade through it all and discern actual value. And as always, follow the money...
Edit 1/2021: It is a shame Amazon recently turned off commenting on reviews. Extensive elaboration and further supporting information to this review and others was therefore deleted. It is not like Amazon is short of storage space. Sad.
I thought this book was fascinating at the time I read it and I still find that to be true. I take vitamins D3, K2, and vitamin A. Hopefully this will keep my bones strong my whole life. Since it works on my teeth, I'm hoping it is also working on my bones and arteries.
