If you liked the first best-selling book about Vitamin D3 by this author (300,000+ copies sold-translated into 10 languages), You are going to LOVE this one! If the first book got us to the 50-yard line- this book is a slam dunk touchdown!The author describes the miraculous new things he has discovered about Vitamin D3 and its 5 cofactors from an additional 8 years of research added to the extensive research he did for his first groundbreaking book.This book has at least twice the vital information contained in his first book and describes in detail how all autoimmune diseases can now be easily defeated without doctors or drugs. How you can virtually bullet proof your health by correcting the 5 deadly deficiencies of the modern age. And the shocking part about this is that doctors in general have no clue as to what is really making us all sick! This book could literally wipe out 90% of the medical industry if everyone adopts its advice.Bold Claims to be sure! Unbelievable? -Yes! But Overwhelming proof is provided for all the claims!Once you read this book, the blindfold will be lifted, and you might laugh and say...."So Simple! Why didn't I think of that?".In this book, cures for every autoimmune disease known to man are described in detail, including a chapter that relates a number of case studies of people who have cured their Multiple Sclerosis with this protocol. And further describes how 100,000+ people from all around the world have cured their MS using this simple information. But it doesn't stop there, cures for many more disease are described, and examples are provided for asthma, psoriasis, COPD, lupus, myasthenia gravis, eczema, Crohn's disease, ulcerative colitis, chronic hives, depression, etc. etc. and even some cases of cancer! The bottom-line premise is simple; virtually all diseases not caused by old age or genetic mutations are caused by an unfocused immune system. Lazy when it comes to bad actors such as viruses, infectious bacteria and fungi, and newly emerged cancer cells, while being hyperactive when confronted with good tissues that should normally not be attacked. The solution? Simply fine tune your immune system to operate correctly, and all these diseases will be a thing of the past. And it is so easy to do. Why don't doctors know about this? Could it be that it is bad for business or were they just taught incorrect information in med school? Hard to say. Most diseases are caused by advice from doctors concerning a hormone that we all make that the author calls the "ultimate biologic". Doctors' advice keeps us all from producing enough of this hormone to remain healthy. Another large segment of diseases is caused by modern farming practices that deplete soils of essential cofactors to this hormone that leave approximately 80%+ of us deficient. Doctors basically never test for this deficiency and know very little about it! Simple neglect and ignorance on the part of health professionals? Or something more sinister?
