A five year study of people with chronic heart failure has indicated that vitamin D3 significantly helps their condition. Per the article:
In the 80 patients who took Vitamin D3, the heart's pumping function improved from 26% to 34%. In the others, who took placebo, there was no change in cardiac function….The findings from the VINDICATE study will be presented at the American College of Cardiology 65th Annual Scientific Session & Expo in Chicago on April 4.
Right. There are a lot of articles online about it. There are also a lot of articles online to the effect that it lowers the risk and aggressiveness of prostate cancer. I take it in a multivitamin pill for men over 50. (I'm 69.)
Thanks, I'd just found this too. Luckily I've known about the benefits of vitamin D for years. My ventricle is stiff too, not nearly as seriously as the patients in the study. Perhaps it would have been worse, had I not been taking 5,000 IU a day.
