I'm afraid it won't be approved by June but your cardiologist should certainly know about it and can explain how it works and keep an eye out for when it finally comes to market. I'm a nurse and when I know anything more, I will post. I just hope it's this year! Also, I read a lot of research and mega doses of vitamin D might add more calcium to the cardiac arteries while a lower dose might help! I take only 1,000 IU now (25 mcg) I used to take 5,000 IU ! Vitamin D is important but not that high a dose!
