“I learned long ago to take with a grain of salt any comments by the “medical establishment” as to the value of nutritional supplements. You’ll see in this article how they used the results of a ridiculous study to try and discredit Vit D supplements while ignoring tons of research documenting its importance. Take charge of your health, do your own research and don’t let some authority figure flimflam you with bogus information.”  Admin

Last November, researchers at the Kaiser Permanente Center for Health Research1 declared that vitamin supplements are probably useless when it comes to preventing heart disease and/or cancer.

Their seriously flawed analysis (which, sadly, is being used by the US Preventive Services Task Force to update its recommendations on supplement use) was widely reported by the media.2

Now, the attack against vitamin supplements has heated up yet again—this time they’re trying to quell the idea that vitamin D, specifically, has any useful purpose for the average person.

Numerous media sources3, 4 have trumpeted the findings of a recent meta-analysis,5 which claims that vitamin D supplements are not only useless against heart disease, stroke and cancer, but may do more harm than good, and that further investigation into vitamin D would likely be “pointless”! According to the authors of the study:

“Available evidence does not lend support to vitamin D supplementation and it is very unlikely that the results of a future6 single randomized clinical trial will materially alter the results from current meta-analyses.”

What’s more, they also found that people taking vitamin D supplements had an increased risk for hip fracture, which prompted Professor Karl Michaëlsson, a researcher at Uppsala University in Sweden, to publish a call for stricter labeling on vitamin D supplements. In his editorial,7 which accompanied the featured analysis, he writes:

“Without stringent indications — i.e. supplementing those without true vitamin D insufficiency — there is a legitimate fear that vitamin D supplementation might actually cause net harm.”

It should be noted that the dose given to the women in the study with increased fracture rates was 500,000 IU, all in one dose. This is an intake the body cannot absorb and process properly and the toxicity of the dose itself was not a surprise to the vitamin D researchers. The increased fractures were seen shortly after the huge dose but the rate declined in later months.

Research Shows Vitamin D Sufficiency Is Critical for Good Health

Meanwhile, a robust and rapidly growing body of research clearly shows that vitamin D is absolutely critical for good health and disease prevention, in part due to the fact that it influences about 10 percent of all your genes.

Just one example of an important gene that vitamin D up-regulates is your ability to fight infections and chronic inflammation. It also produces over 200 anti-microbial peptides, the most important of which is cathelicidin, a naturally occurring broad-spectrum antibiotic.
