Vitamin D and Calcium for Better Blood Sugar
By Jack Challem
You probably know about the vitamin D-calcium connection and that these nutrients are essential for building strong bones and preventing osteoporosis, the age-related thinning of the bones. But new research strongly suggests that vitamin D and calcium also play important roles in maintaining normal insulin function and glucose control — the keys to diabetes.
The federal government's "recommended" daily intake of vitamin D ranges from 200 to 400 IU, depending on age, and doctors and dietitians for years cautioned against taking large amounts of vitamin D supplements. This was because a couple of studies from the 1980s suggested that large doses could be toxic.
But that caution has largely evaporated over the past several years, mainly because those old studies have been rejected due to poor-quality science. Since then vitamin D has entered a nutritional and medical renaissance of sorts.
Now experts like Michael Holick, M.D., of the Boston University School of Medicine, and Walter C. Willett, M.D., of the Harvard School of Public Health, stress vitamin D's safety — and recommend much larger amounts.
An article in Archives of Internal Medicine (2009) reports that vitamin D levels among Americans have decreased over the past 10 or so years. Researchers note that three of every four people do not have adequate vitamin D levels. The numbers may be even worse during the winter months when the sun is low and people spend more time indoors, which interferes with vitamin D production.
The growing consensus is that every man, women, child, and infant should take 1,000 IU of vitamin D daily or 2,000 IU if they have a dark complexion. That may sound like a lot compared to the current 200 IU, but you would have to take 50,000 IU daily — practically a whole bottle a day — for months before you would develop any symptoms of toxicity.

Lows are really nothing new to me. In the past (almost) 22 years, I've experienced every variety of low blood sugar. Two seizures, multiple black outs, the "I'm fine" at 32, the nauseating 85, and everything in between. That certainly doesn't mean that I'm used to them or that each low doesn't feel like a new and treacherous journey. They still scare me. They still annoy me. And they still overrun my life at times. Since I've hit the gym and the calorie counting on an aggressive...
