Studies on vitamin D continue to be published and to prove a myriad of health benefits of the compound.
The most recent report comes out of Kentucky University and has been published in the American Journal of Cardiology.
This was a large retrospective study of a cohort of over 10,000 patients followed in an out-patient clinic system.
The patients were adults over age 18 and had a mean age of 60 years, 71% were female. The researchers looked at data over 5 years.
Using 30 mg/dL as a cutoff, it was found that a remarkable 70.3% of patients were deficient in vitamin D.
It was also found that deficiency in vitamin D was strongly associated with several serious cardiovascular diseases including hypertension, coronary artery disease, cardiomyopathy, and diabetes.
Most importantly those persons deficient in vitamin D were more than two and a half times more likely to die than those patients with normal vitamin D levels ( OR 2.64).
The researchers concluded “vitamin D deficiency was associated with a significant risk of cardiovascular disease and reduced survival.”
They point out that since vitamin D plays an intrinsic role in the expression of over 3000 genes, a deficiency could affect numerous diseases processes.
The current USRDA for vitamin D is 800 iu per day, though 1000 iu or more may be ideal. There is potential for toxicity if too much is consumed.
