I take 5000 IU D3 a day, in a pill that combines 180 mcg of K2. K2 is important for calcium transport. My most recent tested level was 38 ng/ml. I'd like it to be above 40. I also make sure to get a lot of sun, because I think the measured benefits of D3 blood levels might be partly a proxy for sun exposure.

I do similarly. The k2 because I read it can be extra important if you have a history of kidney stones.

  Well and K2 is involved in transporting calcium into bone. So it helps if you are worried about your D3 supplementation altering your blood calcium levels.
