@luckypup I'm not sure if you've seen posts from people recommending MK-4 in 15mg doses, taken 3 times a day to total 45mg, because that's the dosage used in the Japanese studies. I read an article that said taking one 45mg dose was okay and I will do more research on that.

It's hard to find MK-4 supplements in 15mg doses, and they are all pretty expensive. One brand is: Klaire Labs SFI Health Ultra K2 Menaquinone - 4 - Vitamin K2 Supplement with 15mg of Vitamin K2 MK4 per Capsule that is $66 on Amazon.
