Dr. James L Vacek and colleagues from the University of Kansas Medical Center recently released an amazing paper. Last decade, they studied over 10,000 patients for up to 5 years, looking at both their vitamin D levels and if they were taking vitamin D.
First, they found that vitamin D deficient patients [25(OH)D<30 ng/ml] were much more likely to have coronary artery disease, diabetes, swollen heart muscle (cardiomyopathy), hypertension and death. And the difference was not little in most cases, such as 99% of the people with 25(OH)D level > 30 ng/ml lived throughout the study but only 96% of the vitamin D deficient group did, a four-fold difference.
They also found significant difference (p<0.0001) for good cholesterol levels, bad cholesterol levels, and triglycerides. The one thing they did not do is see who was taking D2 and who was taking D3. Remember, do not take D2. If your doctor gives you a prescription for Drisdol or D2, tear it up and get a bottle of 5,000 IU D3 capsules of D3.
The authors end the paper by reminding doctors they can follow the Endocrine Society’s protocol. My only problem with the Endocrine Society’s protocol is that they do not mind recommending D2, when I think studies show that D3 is the one proven to extend life.
