Barely a month goes by when we don’t see yet one more unfounded attack on a vital vitamin or necessary nutrient. It’s become so predictable you can practically set your watch by it. They won’t be satisfied until supplements are removed from the picture completely—and along with them, your freedom to choose.
This time it’s vitamin D that’s been placed on the chopping block, a nutrient critical to combatting bone loss, cancer, heart disease, depression, weight gain, inflammation and very likely diabetes, autism, dementia, autoimmune diseases, chronic pain, high blood pressure, and more.
In fact, this vitamin is SO critical to our health and wellbeing that frankly this latest review trashing this valuable vitamin—published in the April issue of the British Medical Journal (BMJ)—is downright irresponsible. Even worse, when you consider how many of us have a dangerously low vitamin D deficiency, taking the researcher’s conclusions seriously could be as good as signing your own death warrant.
According to the researchers, “Despite a few hundred systematic reviews and meta-analyses, highly convincing evidence of a clear role of vitamin D does not exist for any outcome…”
Besides, it doesn’t take a genius to figure out that BAD science is going to lead to BAD results. And in the case of this BMJ-published “umbrella review,” they should have seen the bad coming from a mile away. Since the researchers chose to include flawed and poorly executed studies in the mix, it really isn’t surprising that the conclusions they reached are essentially rubbish, too.
Vitamin D deficiency seriously bad for your health
Let’s take a closer look at what research has already proven about vitamin D. But we’ll have to just hit some of the highlights, because we’d literally be here all day if I tried to cover EVERYTHING that D is good for.
To begin with, despite its poor execution, the umbrella review in question still showed around an 11 percent drop in death risk for those taking a D supplement. In fact, study after study has shown us the value of this vitamin, demonstrating what a deficiency of D can lead to... starting with trouble for your ticker.
In a seven-year collaboration, researchers from the University of Colorado and Massachusetts General Hospital uncovered evidence linking heart disease and vitamin D deficiency in men and women 65 or older. Seniors with the lowest levels of D were three times more likely to die from heart disease. And those volunteers who had a vitamin D deficiency at the start of the study were 2.5 times more likely to have died from ANY cause by the end of it.
Now a new study confirms that if your vitamin D blood levels fall below 20 ng/mL (or 50 nmol/l), your risk of heart disease shoots up by a third. Even worse, if your levels dip into the dangerously low 10 ng/mL area, your risk for atherosclerosis (the hardening and narrowing of your arteries) doubles!
But your heart isn’t the only organ that craves D: your brain is a big fan too. In fact, over the years research has linked D deficiencies to Alzheimer’s, Parkinson’s, and even depression. And just last year, an animal study—published in the journal Free Radical Biology and Medicine—showed us just how critical the vitamin is to cognitive performance and memory.
D doesn’t just target organ health either… it’s a whole-body elixir that could help to both keep cancer at bay,and drive down your diabetes risk.
Vitamin D targets whole body health
Studies have shown an association between vitamin D and cancer risk, and many experts agree that the vitamin likely offers some protection against a variety of cancers including breast, colon, prostate and bladder cancers. Even mainstream medicine organizations, like The National Cancer Institute, agree that there’s epidemiological evidence linking adequate D levels to a reduced risk.
Research has also revealed that vitamin D could play an important role in preventing diabetes. For example, a Tufts University study found that higher concentrations of D are associated with a lower diabetes risk.
And then there’s the meta-analysis of more than 100,000 people that sheds some light on how it is that D may be driving down diabetes risk. Blood work from 28 different studies revealed that those men and women with the highest D levels tended to avoid the dreaded collection of pre-diabetes symptoms… including high blood pressure, high fasting blood sugars, low HDL cholesterol, high triglycerides, and a large belly... that are commonly known as metabolic syndrome.
The truth is that a vitamin D deficiency and diabetes link is so promising that even the mainstream medicine drones couldn’t ignore it anymore. Late last year the VERY mainstream National Institutes of Health (NIH) finally decided to fund a large-scale clinical trial to explore the effects of D on the disease.
And those really are just a few of the D highlights. There are literally hundreds of studies linking D to good health. The evidence is so vast that public health guidelines here in the United States, as well as those in many other countries, recognize the critical importance of maintaining healthy D levels.
Unfortunately, their D recommendations are entirely too low. That’s why up to 90 percent of us may be walking… or dragging… around with a vitamin D deficiency.
Besides trying to spend a little bit of time every day outside in the sunshine, I typically recommend taking 2,000 to 4,000 IU of vitamin D3 daily. Your doctor can run a simple blood test to figure out what your current levels are.
