I can say I reversed a Coronary Artery Calcium score of over 80 back to zero, with Vitamin K/K2-MK4 (from the study link above) and taking multiple supplements mentioned in the soft plaque link.
Also, I have recently started taking Arterosil, which has studies on its ability to reverse soft plaques. I recently found it available on Amazon. It’s not cheap, but it shows nice results quickly, in the multiple limited studies it’s had.
The Arterosil website is being revamped this weekend, but you can see the prior one, here:
