Vitamin D Deficiency Strongly Linked to Increased Risk of Death

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.

    Interesting! Why, the obsession with lowering the cholesterol? We know it is a precursor to vitamin D, inhibiting the synthesis of cholesterol will also inhibit the synthesis of vitamin D.

    • Alfred Winningham says:

      As someone who was recently diagnosed with high cholesterol and low Vitamin D levels with no prior medication, I doubt it’s as simple as you suggest.

      • David Lynn says:

        If it were that simple, you wouldn’t need a P.H.D. to study it.

        I think there is enough evidence currently to support the fact that Vitamin D is probably the most important supplement anyone could take at this time.

        Whereas Cholesterol lowering drugs known as Statins are linked to an increased risk of Diabetes, liver damage, and neurological issues.

        Your best bet is to take the Vitamin D and control your cholesterol with your diet and possibly a Red Rice Yeast supplement.

    So, does this mean some of them will never die?!?
