Very interesting indeed. I hope it will result in development of a medicine to prevent hardening of the arteries.
Interesting yes, but no explanation for why some people get hardened arteries and others don’t.
Vitamin K2 works to keep calcium in the bones, where it belongs, and out of the soft tissues (like arteries and heart valves). It can also, over time, reduce calcification of the soft tissues - and how quickly is dose dependent. No prescription needed. It is more effective if taken with Vitamin D3 (also no prescription needed, and you can get 5,000 IU gelcaps at Sam’s or Costco for about $0.10 each).
