Vitamin D and heart disease

It is increasingly becoming apparent that it is excessive calcium, and not cholesterol, that causes hardening of the arteries and heart attacks. Only about 3% of arterial plaque is cholesterol while 50% is calcium. Vitamin D is an anti-calcifying agent. [Osteoporosis International 18: 251-59, 2007] Kidney disease patients, who are plagued with arterial calcifications, have 10 times the cardiac death rate compared to the general population.

What most doctors and the public have been told is that high-dose vitamin D can induce calcifications of arteries. But Armin Zittermann, PhD, of the Northrhine Westfalia Heart Center in Germany, reports that both extremely high and commonly low intake levels of vitamin D induce calcification of arteries. Calcification from overdose of vitamin D requires many hundreds of thousands of international units and is rare, whereas hundreds of millions of adults are deficient in vitamin D and suffer from calcified arteries as a result of deficiency. Dr. Zitterman points to a study conducted in Japan where adequate vitamin D levels achieved via supplementation reduced the death risk from cardiovascular disease by 70% compared to those who did not use vitamin D supplements.
