Hight dose K2 had no effect on my CAC score. I'm almost mid-way through a chelation protocol (eventually 40 infusions) and we'll see. Clearly, as I've said before, there does NOT seem to be any sort of linear relationship from low to VERY high CAC scores. Too many have these shockingly high scores with wide open vessels. I suspect this is calcification (without, or with minimal actual atheroma) from endothelial inflammatory disease - possibly stealth infection (ie Bartonella). But, who tf knows??
