Vitamin k2 shows to regulate calcium by driving into bones where needed when calc is supplemented. If not suppl. And calc is high, can k2 help?

Possibly. If blood calcium is high it is almost always due to hyperparathyroidism though you say that has been ruled out- i would have it rechecked in a year or so and see a good internist to try to find what is causing this. But no matter the cause, i would advise at least 1000 mcg of vit k2 each day to reduce chance of calcium depositing in your arteries- see http://bit.Ly/18qtb7y for more on vit k.
