Hi, I’m Rachel McCowen, a health advisor at Life Extension.
Have you ever considered vitamin D deficiency a worldwide epidemic? Hard to believe but, according to researcher Dr. Michael Holick, it has been estimated that vitamin D deficiency is the most common medical condition in the world.
Even more incredible is the fact that vitamin D is not really a vitamin.
A vitamin is a substance essential to human health that cannot be produced by the body. Well … vitamin D is certainly essential to the metabolism of calcium and phosphorous … but it does not meet the second part of the definition since it is produced by our bodies when we’re exposed to sunlight.
When researchers discovered this fact in 1924, they decided to officially keep the “vitamin” name despite the fact that vitamin D is not truly a vitamin.
So you might be thinking … if it’s not a vitamin … what is it and why does it matter?
Since the late 1990’s, research on vitamin D has exploded and it is fast becoming one of the nutrients of the decade. The most exciting discovery is the fact that vitamin D is actually a pro-hormone! In other words, vitamin D will become an active hormone and communicate directly with the DNA in your cells!
That’s exciting ... but a lot to understand ... so let’s break it down into simple steps to see why this is such an astounding discovery and why it has such a profound impact on our health and longevity:
First ... There are two widely recognized forms of vitamin D:
D2 originates in plants and fungi.
D3 is available either through production in the skin after sun exposure or through vitamin D supplementation.
Both forms of vitamin D are metabolized into 25 hydroxy vitamin D ... a prehormone.
And this is where things begin to get very exciting!
25 hydroxy vitamin D is further metabolized into 1,25 Dihydroxyvitamin D … a powerful steroid hormone. It is fat soluble and can pass through cell membranes and bind to vitamin D receptors … where it has many repair and maintenance functions.
It is this new discovery about the 1,25Di-OHD3 form of vitamin D that has researchers so excited. According to Dr. John Cannell, director of the vitamin D Council, 1,25Di-OH affects more than 200 genes in the body and can be found in most tissues in the body.
Vitamin D is the only substance of its kind in the body … which explains why emerging research has identified its role in proper immune function, bone density, heart health, mood disorders, and more!
Wow … pretty phenomenal isn’t it!
For years most of us have relied on food sources and the sun for our vitamin D. But we now understand that these might not be enough. vitamin D potency in food is small compared to the dose we may need. And our ability to convert sunlight to vitamin D is lost as we age, not to mention the fact that sunscreen over SPF 8 blocks this conversion!
Now that you understand the incredible health benefits of this amazing prohormone I’m sure you’re wondering how you can make sure your vitamin D is within optimal levels!
It’s as simple as having a blood test for the circulating form of vitamin D; known as 25-hydroxy vitamin D! This test is offered by Life Extension at a very low cost compared to commercial laboratories.
Since the early 1980’s, Life Extension has stated that the most important step one can take to prevent disease cannot be found in a bottle of pills. The true cornerstone of any preventive health care program is through blood testing ... the ultimate information. What could be smarter? It really is that easy!
Another bonus is that the test results are sent directly to you and can be reviewed with one of our Health Advisors. They will arm you with the information necessary to understand your results, PLUS, you will know how to have a more meaningful discussion with your own doctor.
We urge you to take advantage of this phenomenal opportunity and order your vitamin D blood test today! Or order a comprehensive Life Extension Male or Female Panel and the vitamin D 25 hydroxy blood test is included!
