One-Minute Book Review
Vitamin K2 And The Calcium Paradox: How a Little-Known Vitamin Could Save Your Life – by Kate Rhéaume-Bleue
The premise of this book is that many people get enough calcium and vitamin D, but then a lot of that calcium doesn’t make it past the arteries.
Thus, the calcium paradox: we want to get (usually: more) calcium, but we want it building our bones, not lining our arteries. How, then, to resolve this problem, and simultaneously fight the dual threats of calcium deficiency (osteoporosis) and calcium excess (atherosclerosis)?
The answer, the author argues, is in vitamin K2, of which most people do not get enough, and which is needed to get calcium to where it’s supposed to be.
You may be wondering whether this is somehow 288 pages to say “take vitamin K2”. And, it somewhat is, but there are a lot of details when it comes to things that have historically raised or lowered the amount of vitamin K2 in our diet, what can be done about it in dietary terms if preferring to go all-natural (hint: nattō is an excellent option, but far from the only one), and what other effects vitamin K2 (or its deficiency) can have on us, in many of the body’s systems, far beyond just bone health (and including things as varied as fertility and avoidance of Alzheimer’s).
The style is very easy-reading pop-science, making this quite a quick read, but no less informative. There’s a fair bibliography at the back.
Bottom line: if you’d like to build/maintain your bone density, then the role of vitamin K2 is an important thing to take into account, and if you’re the sort of person who likes to understand things rather than just take them on faith, this book can explain it all very clearly.
