I have written several post of vitamin D and heart disease and there is so much more. There is an exciting article about heart disease and the effect of vitamin D at WebMD.

As we begin our plunge into vitamin D winter then heart disease that has been arrested by getting an adequate amount from the sun will become more active. As you can see from this Harvard news article, it is important to start supplementing with vitamin D. However, here again we find that mainstream medicine is too conservative in the amount of vitamin D. It is better to follow the directions from the home page of the Vitamin D Council to assure that your level of 25(OH)D3 is above 50 ng/ml to have the best effect on heart disease and the upcoming expectation of a serious flu season from the H1N1 virus.
