...vitamin D

The science that you thought was "settled" decades ago ...wasn't. It's all wrong. To state it simply: you are vitamin D deficient.

We all are.

Pajamas Media: Sunshine, vitamin D, and death by scientific consensus.

The "scientific consensus" that has held sway for four decades regarding both exposure to the sun and vitamin D has collapsed. What has emerged in place of the old "settled science" is the knowledge that most people in America are seriously vitamin D deficient or insufficient. The same is true for Canada and Europe, and the implications are staggering.

Simply put, unless you are one of the few people with optimal serum D levels, such as lifeguards and roofers in South Florida, you can cut your risks from most major diseases by 50 to 80 percent. All you have to do is get enough D. It also means we can significantly reduce both health care costs and the staggering national deficit by taking a few simple steps.

...If researchers on the cutting edge are right, the benefits of raising your serum D levels to about 40 ng/ml are enormous. If they are wrong, the risks associated with the recommended therapy are trivial, if not nonexistent, especially if done through supplementation. This is simple Bayesian analysis.

...The stakes are huge, as are the benefits of attaining optimal vitamin D levels. The embarrassment for those who must admit past error, however, may be even greater. The reason is that untold millions have suffered and died prematurely because those who challenged the "settled science" regarding sunshine and vitamin D decades ago were treated like crackpots and demonized.

Now we know that very few people have optimal serum levels of 25-hydroxyvitamin D [25(OH)D], the principal form of vitamin D circulating in the blood. Moreover, those with more melanin manufacture less vitamin D in their skins, so they suffer disproportionately from diseases exacerbated by vitamin D deficiencies.

Dr. Michael Holick, the researcher most responsible for this radical change in thinking, has described the current state of widespread vitamin D deficiency as a "silent epidemic." ....

 We're not getting enough D. The risk of over compensation (i.e., getting too much D through supplementation), is trivial. The danger of not getting adequate vitamin D is health-threatening.

Again "...you can cut your risks from most major diseases by 50 to 80 percent. All you have to do is get enough D." Daily supplements. It's the only way.
