  • About the Book

    This book covers new ground. After extensive investigation and translation of numerous scientific reports into the English language, author Dr. John Cannell reveals a long-held secret once known only to Eastern European athletic trainers. In the 1960s and 70s, it was called Sunlamp Therapy, and it gives athletes a definitive edge over their competitors, particularly for athletes who train for indoor or winter sports. That vitamin D, the sunshine vitamin, improves muscle tone, muscle strength, balance, reaction time and physical endurance, as well as immunity and general health, is a recent discovery in western medicine. It has application ranging from improved performance of standing armies in the field, to Olympic and every-day athletes, and even seniors who need to avert falls and age-related loss of muscle mass and muscle tone. This ground-breaking book is a welcome addition to our current working knowledge of nutrition and health. Read it from beginning to end.
