The research that has come out in recent years concerning Vitamin D has been nothing short of scientifically mind-blowing. Back in the 1960's the sum total of this nutrient was that its deficiency caused rickets, it was fat-soluble, more than 400 iu (International Units) was unnecessary, and 800 iu was toxic, for Pete's sake!
For sure, Vitamin D is important for the absorption of ingested calcium - if you don't get enough of it, you don't appropriately absorb calcium. So, clearly it's important for the health of our bones. If you are low in Vitamin D, you're at risk for osteoporosis.
But then, after a long history of 'nothing new in that area', Vitamin D exploded onto the scene as a multi-faceted nutrient of unbelievable versatility.
Information came to light concerning how important it is for our muscles, too. The tightening and relaxation of all our muscles is highly calcium (and magnesium) dependent. You can develop cramping, muscle aches and even pains that can get misdiagnosed as Fibromyalgia or Chronic Fatigue Syndrome.
And we're just gettin' started. The ultra-biggie came with the discovery of how important Vitamin D is concerning normal functioning of our immune system. At about the same time, it was discovered that the fears concerning toxicity from this fat-soluble nutrient were not only over-blown, but that nearly all of us were getting way, wa-a-a-y too little of the stuff...
Wouldn't it be nice to have a simple, natural agent that stimulates our immune system?! Well, Vitamin D is pretty much IT! In fact, it was found that, when taken in thousands of iu (instead of the standard hundreds), all sorts of immune stimulating benefits were seen (however, since this 'vitamin' is actually a hormone, check with your doc concerning what dose might be right for you). People with long histories of all sorts of illnesses, allergies, and complaints were finding clear benefit just from adding extra Vitamin D.
But, when using proper doses, the list goes on:
● Vitamin D also has anti-cancer properties and may prevent various cancers.
● Vitamin D may prevent heart disease.
● And, though it seems completely unrelated to the 'bone-building vitamin', vitamin D may even prevent diabetes.
It's true. A recent article in Diabetes Forecast magazine states,
"It turns out that there are vitamin D receptors almost everywhere in the human body-even in the islets of Langerhans, the structures in the pancreas that produce insulin. For people with type 2 diabetes or pre-diabetes, it seems that Vitamin D allows the body to secrete more insulin. At the same time, there's evidence that vitamin D may increase insulin sensitivity."
Other articles, both at that source and elsewhere, have picked up on the same finding, noting particularly that current recommended levels are inadequate to take advantage of the benefits possible from the remarkable substance.
Though the ideal source of Vitamin D should come from proper sun exposure, today's lifestyles, combined with media fears of 'too much sun', and the current use of nearly constant sunblock 'protection' make it even more likely than ever that most people don't get enough.
But there's another issue: the cheapest form of Vitamin D (D2, or ergocalciferol) is synthetic. So, being a form that's not exactly the molecule the body prefers, it's poorly absorbed. It is, however, cheaper than 'the good stuff', and therefore has been used most everywhere as the agent-of-choice for Vitamin D supplementation. That's not how we do it at MRC. Our Vitamin D is 100% natural vitamin D (D3, or cholecalciferol).
