  • 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.

    Researcher William B Grant PhD of the Sunlight, Nutrition & Health Research Center suggests a doubling of the blood serum vitamin D levels (from 54 to 110 nanomole/liter) would be the most cost effective way to reduce global mortality rates. A recently published study confirms Dr. Grant’s assertion. A study of 7531 US adults showed those with the highest vitamin D levels had the lowest mortality levels. 21266455 While researchers are sorting out scientific squabbles over dosage, most Americans are D-deficient at some time of the year, and low D levels are certainly associated with excess mortality. There is no argument about that. Sunshine cost nothing and vitamin D pills are cheap, so there should be no excuses for Americans to delay in incorporating vitamin D pills into their daily health regimens.

    It’s no time to be left standing on the fence. It’s time to get some vitamin D, called the 10-cent vitamin because it can be economically purchased in doses ranging from 1000 to 5000 international units. Dr. John Cannell’s latest book about vitamin D provides details on how to raise vitamin D levels. – Bill Sardi, August 8, 2011
