I take vit D2 every Saturday as medication, not a supplement. Would I still have to worry about my arteries getting clogged if I don’t take anything to metabolize it?
I’m 35 if it matters, but am on cholesterol medication because bad diet.
Arterial calcification is a very bad deal. When in the heart, it leads to things like valve replacement surgery. So there is a very real incentive to err on the side of caution.
Give this article a read and you'll find that vitamin K2 supplements generally improve bone and heart health :

Personally I would not supplement long term with a D vitamin without also supplementing long term with a K2 vitamin (specifically K2). Every body is different and you have to find what works for you. At thirty-five you have plenty of time to fix that diet and recover. (Look into red yeast rice as well for that cholesterol.) Make a ten-year plan! Good luck, FRiend!
