Vitamin D-3 and Reducing The Risk of Heart Disease

Crystals of Vitamin D

Vitamin D3 – which is made by the body naturally when skin is exposed to the sun – can significantly restore the damage to the cardiovascular system caused by several diseases, including hypertension, diabetes and atherosclerosis.


Patients who have a heart attack often will have a deficiency of D3. (It doesn’t mean that the deficiency caused the heart attack, but it increased the risk of heart attack.)

Vitamin D3 is a powerful stimulator of nitric oxide (NO), which is a major signaling molecule in the regulation of blood flow and the prevention of the formation of clots in the cardiovasculature.

Vitamin D3 significantly reduced the level of oxidative stress in the cardiovascular system.

This study is the first to identify the molecular mechanism of vitamin D3-triggered restoration of the function of damaged endothelium in the cardiovasculature.

Dr. Parker’s Commentary 

The research is promising in its ability to measure cell functioning at a micro level.

Note that this is not the same as saying that if you take Vitamin D-3 supplements it will have the same effect; this is material for other research.   A basic review of the research can be found by following the Wikipedia link two paragraphs below. 


In 1922, Elmer McCollum tested modified cod liver oil in which the vitamin A had been destroyed. The modified oil cured the sick dogs, so McCollum concluded the factor in cod liver oil which cured rickets was distinct from vitamin A. He called it vitamin D because it was the fourth vitamin to be named.
