Definitely take the K2 (or get it via diet) if you’re taking D3.
Organ meats, egg yolks and some hard cheeses have K2. You know, all those things we’re told not to eat or we’ll have a heart attack? Turns out that advice may have been misleading.
I take Thorne’s drops for K2 (MK4). And something from Jarrow whose name escapes me right now that’s a bone building supplement that has MK7 and a bunch of minerals besides.
I take 680 mg of strontium and 500 mg chelated magnesium to build bone, or to fight osteoporosis.
