2.0 out of 5 stars Out of date!, 21 April 2013
Verified Purchase(What is this?)
This review is from: The Vitamin D Solution: A 3-Step Strategy to Cure Our Most Common Health Problem (Hardcover)
The author is way behind. It's difficult to see how a supposed expert could fail to include the crucial relationship between all aspects of vitamin D and its close connection with vitamin K2. There is not a mention in the book about this which negates a large area of the authors advice regarding maintaining an appropriate intake of vitamin D and this surely places his credibility in question.

After reading this comment, I bought this book somewaht feeling I was rolling the dice, despite all the other positive comments. Now that I've read the book I think this is an unfair rate and comment. Most vitamins and minerals, amino acids and other nutrients have synergistic and complimentary effects. This book is about what it states in the title: vitamin D. Not other vitamins, like K, C, or minerals, like magnesium, boron, calcium, etc. If the author purpose was to talk about other vitamins this book will be superficial in the theme of vitamin D. Sure he could mentioned vitamin K, calcium and others, but he would also had to alert for the dangerous and correct intake of this vitamins/minerals. Beware vitamin k, being a natural blood clotting, has several interactions, like with warfarin, and other harmful side effects. There's a huge global proved deficiency in vitamin D, doesn't so with vitamin K, the recommended intake of vitamin D is mostly safe for everyone, the side effects and interaction on vitamin D are negligible and easily surpassed. To achieve the correct values of vit. D is almost impossible, for most of people, thru food or the regular everyday sun exposure. Vitamin K deficiency is rare, your body only need a small amount of vitamin K (only 80μg micrograms/daily - vitamin D minimum is 1000mg/daily), and is easy to achieve the correct levels, if you drink soy milk or eat prunes, dark leafy greens, broccoli, asparagus, cucumber, cabbage, Spring Onions, etc. A book worth reading if you care about vitamin D. If you're looking info on vitamin K there several choices like this one Vitamin K2 and the Calcium Paradox: How a Little-Known Vitamin Could Save Your Life

Nikos, I'm currently reading the book that you linked to and it says the opposite, that K2 deficiency is widespread, K2 is very important with D3. The reason that K2 has come to peoples attention only more recently is that although it was discovered to be doing what it was doing about 70 years ago it was overlooked because there was a misunderstanding back then. The book goes into greater detail, I'm 18% into the book so far so can only comment this far.
