With the overwhelming amount of information and misinformation being thrown at us on a daily basis, especially in regards to our health, how do we figure out what we really need to pay attention to?  One expert will sound the alarm and then the next will cry BS.  We’re left confused and frustrated… plus if everything is so important, then nothing is, right?


My goal is to wade thru the clutter and highlight topics and research that matter to your optimal health.  With that said, science is showing that VITAMIN D is one thing we all need to pay attention to for 2 reasons… it’s critical to our health and about half of us are deficient.


Below are 5 critical points on vitamin D and 1 outstanding non-profit project we can all participate in to battle the problem.


  1. Our bodies are designed to produce vitamin D from sun exposure.  Most of us are spending more and more time indoors and when we are outside, we’re either covered up or covered with sunscreen.  What you may not know is that it can take up to 48 hours to absorb most of the vitamin D into your blood, so the sooner you shower off, the less you get.

  2. On average, the body uses about 4,000 IU/day of vitamin D.  With limited sun exposure and an RDA of 400 IU/day… we obviously have a problem.

  3. Before the Human Genome Project, it was estimated that we had up to 2,000,000 genes.  Now we know it’s just north of 20,000 and vitamin D is needed for the regulation of over 2,000 of them… that’s 10%!

  4. If I had a nickel for everytime I’ve heard “there’s not enough research to support it”, I’d have lots of nickels.  The truth is that there are thousands of studies to backup the importance of vitamin D… Greenmedinfo.com currently catalogs 238 of them.  One of my favorite studies looked at 3 million incidence of cancer in relation to the amount of UV-B exposure by location and factored out other known risk factors.  New research in the last couple months shows a direct link between vitamin D levels and insulin resistance.

  5. Science is not just saying “Take more vitamin D”, the research is piecing together specific serum vitamin D levels with reduced incidence of diseases ranging from cancer to heart attacks to bone fractures.  This might change as more research is done, but the sweet spot seems to be about 60 ng/ml, with a minimum of 40 ng/ml.


All of us need to get tested, take action, and then get retested.  Here’s a great chart to talk to your doctor about as you work toward the sweet spot.


Of course you can get this done on your own, but why not be a part of something pretty cool?  The Vitamin D*action by GrassrootsHealth is a non-profit project dedicated to understanding how vitamin D impacts our health.  Some of the leading experts on the subject are involved in this project.  Currently over 7,000 individuals are participating and about 50% of them were under 40 ng/ml when they started.  Click here for more information and/or to get tested.


Listen, you might as well just do it, cause I’m going to keep bugging you until you’re at least 40 ng/ml.
