Just an additional note: There are two kinds of Vitamin K2: K2-MK4 and K2-MK7. It’s the K2-MK7 that works well with Vitamin D3.

Thanks. I just looked at my bottle of K2 and (fortuitously) have MK7.

We actually make sure we get both the MK4 and MK7 varieties. They are both bioactive and have slightly different modes of action.

FWIW I think it’s the MK7 that’s worked against the cavities.
