Want to improve your immune system? Then you need to read this book. I live in a sunny area and have young kids, and thought they would get well more than enough d3 from the sun. Come the beginning of winter, we suffered costant colds and flu’s. Not this winter! Not a single sniffle since we all started D3 and K2. We’d tried heaps of supplements abd probiotics prior to this, but nothing works as well as this combination. One of my sons is at kindy, and all parents know how horrible kindy colds are. But no cols flu’s or anything else since we started these supplements. My Thank you Jeff for such a great book – I really appreciate your work!
