    About Dr. John Cannell’s New Book: The Athlete’s Edge FASTER QUICKER STRONGER WITH VITAMIN D

    Dr. John Cannell’s new book is about a revolution that should have started decades ago after vitamin D was first identified by Edward Mellanby in 1922. Modern medicine kept vitamin D in a dark closet and instead rolled out man-made drug after man-made drug. There was a day when there was only quinine, wine, opium, digitalis from foxglove and a few other assorted elixirs. That was prior to aspirin which was commercialized in the 1930s, and then penicillin, discovered in 1928 and commercialized in the 1940s.

    Hospitals were treating lung tuberculosis with sunshine, called heliotherapy — a somewhat crude way of obtaining natural vitamin D3. But as Dr. Cannell reveals in his new book, German athletic trainers began using sun lamps in the 1960s to tone up muscles of competitive athletes decades ago and kept it a closely-held secret.

  • The Most Desired Invention Is ………… ?

    August 8, 2011: by Bill Sardi

    What’s the quickest, cheapest, least inconvenient way to improve the lives of Americans? It’s not biodegradable plastic which one MIT survey showed consumers thought would be the most desired invention that would change their lives. Actually it’s already been invented, by nature. It is produced by sunshine and explains the “season of death and depression” in winter months. It is vitamin D.

    Americans are slowly catching onto the Vitamin D story, which is actually a belated development. This hormone/vitamin was discovered in 1922. Sales of vitamin D pills have risen in recent years from $40 million to $450 million a year, but that still only comes to about $1.45 per person per year. If one third of the American population began taking vitamin D pills @$10 per month that would equal roughly $12 billion in annual sales. It would be the first blockbuster vitamin pill.

  • NEW BOOK: ATHLETE’S EDGE: FASTER, QUICKER, STRONGER WITH VITAMIN D (John Cannell MD). Will Vitamin D Become The New Performance-Enhancing “Drug?”

    August 3, 2011: by Bill Sardi

    With release of a report from the annual meeting of the American Orthopaedic Society for Sports Medicine, that low blood levels of vitamin D are more common among NFL football players who suffer muscle injuries, there is no better time to talk about vitamin D and sports with the release of Dr. John Cannell’s newest book, entitled ATHLETE’S EDGE: FASTER, QUICKER, STRONGER WITH VITAMIN D.

    Readers will get the instant impression that this fully-illustrated 318-page book will make an impact, not just on individual athletes but also on entire sports the way performance-enhancing drugs did for baseball, but this time, it’s a natural (and legal) molecule that is involved.
