Low levels of vitamin D are known to nearly double the risk of cardiovascular disease in patients with diabetes, and researchers now think they know why.
Diabetics deficient in vitamin D can't process cholesterol normally, so it builds up in their blood vessels, increasing the risk of heart attack and stroke. New research has identified a mechanism linking low vitamin D levels to heart disease risk, and may lead to ways to fix the problem, simply by increasing levels of vitamin D.
Vitamin D inhibits the uptake of cholesterol by cells called macrophages. When people are deficient in vitamin D, the macrophage cells absorb more cholesterol, and can't get rid of it. The macrophages get clogged with cholesterol and become what scientists call foam cells, which are one of the earliest markers of atherosclerosis.
Macrophages are dispatched by the immune system in response to inflammation and often are activated by diseases such as diabetes.

There is no way to know if the above recommendations are correct. The ONLY way to know is to test your blood. You might need 4-5 times the amount recommended above. Ideally your blood level of 25 OH D should be 60ng/ml.
