189: MK-4 vs MK-7: Vitamin K2 Showdown

Introduction

Question: MK-4 vs MK-7: Vitamin K2 Showdown

My default here is that a healthy diet would always have a mix of all of them. And although it's hard to justify a reason for having K1 specifically if you also have MK-7, the justification for having MK-4 is somewhat speculative. I wouldn't say speculative, but it's at kind of the theoretical level. So basically, MK-4 is not very good at supporting blood clotting, but MK-7 and K1 are. And we know that from human trials. And so we can at least say, you shouldn't only get MK-4, because it's not very good at supporting blood clotting.

As default, get your K1 from veggies and then try to get a mix of MK-4 and MK-7, that totals up to 2-400 micrograms per day for the people who are just talking about one to 200 micrograms for general people, that can come from food if you eat those foods and supplement if you don't.
