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.
