Roughly 4-5 years ago, the local medical imaging facility sent out a flyer advertising February’s heart month special for calcium heart scans. About $179.00. So I bought 2, 1 for both my wife and I. When my wife’s score came back terribly high, and revealing a 85% blockage in her LAD, I started researching calcium scores and treating the build up. That’s when I came across a book titled, “Vitamin K2 and the calcium paradox.” Very good book. But, being the skeptic I am, I researched it and found, especially in European medical journals, that K2 has some significant benefits in most people. I also take D3 5000, small doses of A, and some other basic vitamins. I also follow Dr William Li.
