Jeffrey Bland, Ph.D., world-renowned nutritional biochemist, has called the book a "...very well-written and useful contribution on the history and clinical application of vitamin therapy in health care....Dr. Janson has been a recognized clinical leader in nutritional medicine for nearly 20 years. He is one of those special people who lives what he preaches and is an example of what attention to nutrition and vitamin status can do for health and performance....much of his experience has been incorporated into his book, which makes it accessible to tens of thousands of readers...If the proof of the pudding is how one's health is maintained as they move into their 50's, then Dr. Janson's book should provide a useful guide for most health aspirants."
