When everything is in balance and the body can exist in perfect rhythm with the environment (the way it was supposed to run) then there wouldn't be a need for any supplement except food.

But my guess is that you don't live in a unlit, uninsulated grass hut in African and hunt for food everyday and therefore could use a little supplemental help. :)

Your diet is definitely high in K2 which is great but I would err on the side of caution and suggest to keep taking your supplement until goals are reached 100%. So many small things like touching plastics, breathing car fumes, checking your phone at 10:30p, brushing your teeth, not eating dirt covered food...etc etc put extra stress on the body.

I would recommend this article on vit k by Chris Masterjon, it's pretty awesome. I personally eat a diet similarly high in k2 but still supplement rather aggressively. I take around 5mg a day most days, with my D and A. Note that this is an attempt to correct a D deficiency identified in my most recent labs, so YMMV.
