“In this long-needed book, Pacholok and Stuart expose a major health-care scandal . . . . [and] provide an invaluable service for medical consumers who want to protect their families and for all medical care providers who truly care about their patients. An important, highly recommended contribution.” —Bernard Rimland, PhD, director, Autism Research Institute “Sally Pacholok and Jeffrey Stuart are to be congratulated for calling attention to this common disorder that affects a significant proportion of the population, particularly among the elderly. . . . I recommend this book to professionals and patients alike.” —Kilmer McCully, MD, author, The Homocysteine Revolution and The Heart Revolution “This is the definitive book on B12 deficiency, diagnosis, and treatment for the lay reader and for the interested physician. As a result of reading this book, I now routinely test serum B12 and Urinary MMA on ALL patients, and have been surprised to find many symptomatic B12-deficient patients completely missed by the medical system.” —Jeffrey Dach, MD “I defy you to read this book then not get yourself or a loved one tested for B12 deficiency.” —Eric Norman, PhD, developer, the UMMA test for B12 deficiency, and founder, the first commercial laboratory to provide UMMA testing
