inadequate and outdated,
This review is from: Health Benefits of Vitamin K-2: A Revolutionary Treatment for Heart Disease and Bone Loss (Paperback)Another reviewer has already expressed concerns about the authors' credentials as well as the lack of research details to back up many of the claims in this thin book (less than half of which is actually about K2), concerns that I echo.
It's actually worse than this as it's peppered with errors: the book states in more than one place that we all get enough vitamin D, for instance.(Vitamin D works synergistically with K2.) That's just not true. There's been a huge amount of research over the last 20 years (and more) showing worsening levels of health the further north we live. It is also now well-known that very few people living north of parallel 40 get enough vitamin D (this includes England).
A far better book is "Vitamin K2 and the Calcium Paradox"by Kate Rheaume-Bleue; better researched and well-written in a friendly, clear and organised way. It explains how taking calcium and/or vitamin D can kill you if you don't also supplement with K2 and much more.
