Jarrow Formulas Mk-7 is naturally made via fermentation by Bacillus subtilis subsp. natto and is much better absorbed than K from spinach. Mk-7 is a longer-acting form of vitamin K versus K1 and Mk-4, and better support carboxylation of specific proteins needed to build bones and support cardiovascular health.
