I would advise taking a K2 MK7 supplement with D3, or get a supplement that contains both. Personally, I take one capsule a day that contains both 3000IU of D3 and 100μg of K2 MK7.
D3 by itself can cause high calcium levels, to the point of toxicity in very high doses. The K2 moves the calcium from the blood to bones.
