I take a number of supplementa, but recently decided to add Vitamin K. Actually the two forms K or K1, and K2 have different uses and act on different enzymes.
1. Vitamin K1 is required to activate the proteins better involved in blood clotting. It is an important anti-inflamatory. Chronic inflammation leads to bone loss.
2. Vitamin K2 is required to activate the proteins that determine where calcium goes in our bodies, making sure that the calcium we absorb goes into our bones where we want it and not into our arteries or our hearts where we don’t. That’s the job of the proteins activated by K2.
If you’re taking Vit D, you should always take K-2, specifically for reason #2 in your post.

I take 200 mcg/day (150 of MK-7 & 50 of MK-4) and 5,000 IU of Vit D3.
After surgery in March for a broken kneecap, I was researching diet for healing bones .... Vit D & Vit K-2 were on the list, plus lots of protein & I added some other supplements I thought would help. My Ortho commented on what a “speedy healer” I was and I have no doubt what I was eating/supplementing made a huge difference.
Its important to take D3 and K2 together. D3 pushes the calcium into your system and then K2 pushes it into your bones.
