Vitamin D saves lives—so why won’t docs prescribe it?

The amount of research money we throw at investigating things we already know never fails to stupefy me. Neither does the amount of publication space devoted to publishing the conclusions—as if no one had ever thought of them before…

If I sound angry, it’s because I am. Too much money is wasted on unnecessary, repeat research. Especially on vitamin supplementation—because heaven forbid, we actually accept the fact that they might offer your body more than just “expensive urine.”

And I really can’t think of a more frustrating example than vitamin D.

Safe, natural, and lifesaving

I recently came across a new study showing that high-dose vitamin D3 supplementation may benefit patients with metastatic colorectal cancer. This is obviously great news, so let’s take a look at the results.

This study—called the SUNSHINE phase 2 trial—featured 139 patients with metastatic colorectal cancer, all receiving standard chemotherapy. Half of them received 400 IU of vitamin D daily (a “standard” dose), while the other half received 8,000 IU daily (a “very high” dose) for two weeks, followed by 4,000 IU per day after that.

Researchers found that patients who took the “high-dose” vitamin D were 36 percent less likely to die or see their disease progress over the next two years of follow-up. There was also a significant difference in the amount of time before the disease worsened—a 13-month median delay, versus an 11-month median delay.

These are incredible results, with more than a third of patients seeing a pretty dramatic benefit.

Yet instead of giving their wholehearted endorsement to vitamin D, the study authors claim “confirmatory trials are needed, ideally with longer follow-up to obtain better estimates of effects on survival, as well as biological measurements to clarify underlying mechanisms.”

And how many people have to die before all of these “confirmatory studies” are completed? Here’s my answer: Too many.

A “standard dose” simply isn’t enough

The good news is, a phase 3 trial to look at overall survival times is coming. But then and only then will these bozos admit that vitamin D should be part of standard treatment for metastatic colon cancer patients.

Here’s why that’s so infuriating: Nearly all of the trial’s patients were deficient in vitamin D when they enrolled in the study. And not surprisingly, the pathetic “standard dose” did nothing to raise their blood levels.

The average vitamin D level remained deficient at around 18 ng/mL for the duration of the trial. Meanwhile, those taking the “high dose” still needed a whole three months just to break 30 mg/mL—which is sufficient only by the most minimal standards.

That’s why this “very high” dose is actually on the lower end of what I recommend to my patients. In fact, you may recall that I recommend up to 10,000 IU daily—which is what I take myself. In the warm summer months, you might be able to go lower (I personally scale my dose down to 5,000 IU), but only if your blood tests show that you’re absorbing enough vitamin D through the additional sun exposure.

Speaking of blood levels, just about every study out there shows that the sweet spot is a vitamin D level around 80 to 90 ng/mL. And yet, I can’t tell you how many times I’ve been ridiculed by other doctors for keeping my patients’ levels of vitamin D this high. I’ve even been told that I’m making them “toxic.” But as far as I’m concerned, these conventional medicine flunkies with NO training in nutrition or supplements should keep their traps shut

The simple fact is, most people need so-called “very high” doses to reach these optimal blood levels (which, once again, are backed by solid scientific evidence). And despite what these hand-wringing mainstream M.D.s want you to believe, it’s extremely hard to overdose on vitamin D.

Vitamin D is readily available, inexpensive and very safe—so what are you waiting for? If you haven’t already, add this life-saving vitamin to your daily routine TODAY.
