@singingbones I just started yesterday. Taking AOR Peak K2, which is 15mg each pill. I am taking 2 to start and 1 K2 MK7 200 mg for this week and going to 3 of the 15mg pills starting Monday.

@singingbones For a couple months, I've been taking: 180mcg Menaquinone-7 (MK7) - TrueVantage brand and 45,000 mcg (45 mg) of vitamin K2 (menaquinone-4) - Life Extension K2 High Potency brand.

I am considering switching to a MK4 supplement that comes in three 15mg doses, but they are a lot more expensive than those that come in one 45mg dose. I know that's what was used in the Japanese studies. However, I read this article: https://threearrowsnutra.com/blogs/ironwarrior/mk4-vs-mk7
It says: "MK4's serum half-life is roughly two hours — and that rapid disappearance from blood isn't a weakness. It's the opposite. Your body pulls MK4 straight into the brain, bone, kidney, pancreas, and reproductive organs. What leaves the bloodstream fastest may be doing the most work. If a nutrient's invisible in a blood draw, it's often because it already reached where it needs to be."
