Best ways to consume adequate to plenty Vitamin K2 for health & longevity? Cofactors?

Vitamin K2 ((Activator X) from Dr. Weston A. Price's work) seems very potentially crucial to overall health and longevity.

There are studies linking healing of calcification in arteries via K2. It activates vitamines A & D. There are suspicions tying it to all manner of Paleolithic peoples' diet, and resultant health. Paleolithic-type peoples Weston A. Price studied were supposedly replete in an abundance of K2 in their diets, at least as compared to modern-day diets.

Were Paleolithic peoples in general replete with K2?


There seems to be very little research as to an optimal intake, and even less into the amounts of K2 contained in various whole foods.

There is also some debate as to the MK-7 and MK-4 forms differing in effectiveness.


What are whole food sources for K2? The fats and organ meats of grass-fed cows (and presumably some other grass-fed animals)? Wild game? Fermented foods?

Many supplement their diets with raw dairy. Is there more K2/g in dairy than the other fats of the cow?

Can it be consumed adequately in a Paleo diet today, or is supplementation wise?

If supplementation, are there concerns as to the deriving processes, impurities, differences in form from K2 in whole foods, or anything else?


And, save for sunlight (vitamin D), and organ meats/meats (vitamin A/retinol), and calcium(bones/bone meal...?), how does one generally obtain the proper cofactors for vitamin K2 (magnesium/soil depletion, zinc, ...?)?

Or, does a discussion of proper cofactors sort of spiral out into all micronutrient deficiencies, because they are all interrelatable?

If you are focusing on K2 alone, natto is off scale. For zinc, by far the best common source is beef. It is not nearly as high as oysters, but when you compare daily eating of beef with once a year oyster platter, beef dominates. You want to make sure your cattle had mineral supplements, for example here in the Midwest soils are zinc-deficient. For magnesium, I am lucky the soil of my garden has above optimum Mg. I just get a lot of it from my veggies, whether I want it or not, but typically compost will have a lot of Mg, so just eat organic vegetables, specially greens.
