High vitamin butter oil is a good source of K2, but to my knowledge, there is no published data on the amount of K2 in it. The best I could find was from the book Vitamin K2 and the Calcium Paradox which lists pastured butter as containing 15 mcg per 3.5 ounces/100 grams.
Emu oil contains significantly more vitamin K2 than pastured butter with each 3.5 ounces/100 grams containing 360 mcg (24X more than pastured butter), so capsules of high vitamin butter oil would contain a fraction of the K2 as compared with capsules of the emu oil based on this data.
I think the bottom line is to get K2 from a wide variety of whole foods particularly given that the amount of K2 in a food can tend to vary. The Australian Emu Oil provides an excellent option, particularly for those who are allergic to dairy or do not have access to pastured products, to ensure that this critical nutrient is being consumed in adequate amounts and in potent form as MK-4.
