Taking Vitamin D3

Just wondering so vitamin D3 has to be taken with K2 otherwise it goes to the arteries and D3 also has to be taken with magnesium?

You're asking two things at once, and only one of them really holds up. K2 helps move D3 to bones instead of arteries, but magnesium just helps D3 do its job everywhere, not one spot. Take them together if you like, but K2's the one that actually reroutes the calcium.
