May I ask what supplements you used for the CAC reduction?

I had already been taking Vitamin K2, but my supplemental dose was just 50% over the amount given for their “normal” vitamin K group!
What I used was two months of Koncentrated K, at one capsule a day, to get really close to the amount described in the study. Since then, I now take double the normal amount of Vitamin K / K2-MK4 / K2-MK7 that I did to wind up with the calcium.
I will probably take more Koncentrated K if any more calcium shows up.
Do note that calcium on your arteries is effectively from ruptures of soft plaques. Your body uses the hard plaque to fix what it found, but the “calcium patch” has its own issues. That study, and people taking warfarin, can have their arteries coated with calcium, over time, and not even from soft plaque rupturing. I know it prevents blood clotting for such person, but there are now other ways to address it, and it's even possible to take vitamin K/K2 while taking warfarin, it's just that your doctor will need to adjust your warfarin dose to compensate.
So, removing just the calcium without addressing the underlying soft plaque is not necessarily the best approach.
What have I done to address the soft plaque?
I have been more diligent on eliminating all refined sugar and wheat sources. I do eat plenty of veggies and generally are always lower carb to even keto in my diet. I have brought in more avocados and olive oil, too.
For supplements, I have more recently been taking nattokinase and lumbrokinase, on alternate days. I take 300 mg of Pantesin pantethine, twice a day. I take fucoidan, bergamot (or have bergamot tea), and tocotrienols daily. We also occasionally eat kelp, which can have rhamnan sulfate, also shown to rapidly reduce soft plaques.
I explain most of this, with links, in this older post in a different thread.
