Vitamin D has recently been at the forefront as one of the go-to vitamins to supplement with.
If you’ve ever heard from a doctor or a friend you should be taking Vitamin D, then those claims aren’t baseless and should be taken quite seriously.
Vitamin D has proven in study after study to be one of the most important vitamins for human health.
In fact, Vitamin D deficiency has been linked to a myriad of chronic health conditions.
Just a handful of these conditions are:
- Hearling Loss
- Heart Disease
- Cystic Fibrosis
- Diabetes 1&2
And many, many more.
Most Americans are severely deficient in Vitamin D for a number of reasons, the leading of which is a lack of exposure to the sun.
As Vitamin D can be produced in your body through exposure to natural sunlight, far too many people never receive the proper amount of sunlight. The optimum amount of sunlight is roughly 10 to 15 minutes a day, in direct sunlight, with at least 40 percent of your skin exposed.
These numbers need to be higher in the winter as the power of the suns rays are diminished in the winter months. Unfortunately, not many people are able to make it outside in winter months with 40% of their skin exposed for an hour.
Another reason Vitamin D levels are lower is many people have followed the popular recommendation of wearing sunscreen when being exposed to the sun. While many people believe they’re helping their skin out by following this protocol, the opposite is true.
Sunscreen blocks out important UVB rays which are essential in the body’s production of D3.
As this is the case, one of the oft recommended courses of action is to supplement with Vitamin D. And this is absolutely one of the soundest methods for reversing any deficiency in Vitamin D your body might experience.
The only problem is most people aren’t aware there are two forms of Vitamin D and one is not only better than the other, one can actually be dangerous.
There are two forms of Vitamin D: Vitamin D2 and Vitamin D3.
Vitamin D2 is known as Drisdol and is a synthetic form of Vitamin D. It’s produced through the irradiation of fungal and plant matter and is the usual Vitamin D prescribed by Docs.
Unfortunately, the mortality rates of those who supplement with Vitamin D2 is actually higher than those who supplement with D3.
The analysis of 50 randomized controlled trials, which included a total of 94,000 participants, showed:
- A six percent relative risk reduction among those who used vitamin D3, but
- A two percent relative risk increase among those who used D2
According to the Vitamin D Council:
You would think a paper that took a look at tens of thousands of subjects and analyzed the efficacy of prescription vitamin D (D2) and over-the-counter vitamin D (D3) would warrant a news story or two.
To my knowledge, these papers are the first to paint such a clear picture about the efficacy between D3 and D2.
While there may be explanations for D3’s superiority other than improved efficacy, for the time being, these papers send doctors a message: use D3, not D2.
And yet MDs across the nation still aren’t keen to these facts.
As Mercola notes:
- According to the latest research, D3 is approximately 87 percent more potent in raising and maintaining vitamin D concentrations and produces 2- to 3-fold greater storage of vitamin D than does D2.
- Regardless of which form you use, your body must convert it into a more active form, and vitamin D3 is converted 500 percent faster than vitamin D2.
- Vitamin D2 also has a shorter shelf life, and its metabolites bind poorly with proteins, further hampering its effectiveness.
These reasons alone should be enough to switch to D3.
And if you need one more reason to supplement, just remember, if you can’t make it out in the sun, it can potentially safe your life.
