Cancer, Men's Health, Nutritional Health, Woman's Health
Readers of this blog know that, in general, I'm in favor of healthcare professionals checking vitamin D levels as part of routine exams. I do this on all adolescents and adults. And, I've blogged more on the topic of vitamin D this year than any other topic. So, I'm trying to post less on the topic, but this and the next too blogs were too important not to mention to you.

Vitamin D3, or cholecalciferol, is more…

This is according to research presented at the American College of Cardiology annual meeting. In the past, "researchers have been uncomfortable randomizing people with low vitamin D into a group that ... does not" receive treatment, because deficiency "can contribute to weaker bones and" has "been associated with increased risks of several diseases, including several types of cancer." The Salt Lake Tribune reports that the researchers reported that "patients who increased their vitamin D levels to 43 nanograms…
