Premium Supplements Dietary Supplement Soy Free Dr. Mercola Has Been Providing Quality Products Since 2001 One of the best natural sources of vitamin K2 comes from an ancient Japanese food called natto. That's why my Vitamin K2 is formulated using chickpeas fermented with Bacillus subtilis natto. Unfortunately, as much as 99% of the population is deficient in this vitamin. That's especially unfortunate when you consider vitamin K2's benefits… Helps you maintain strong bones and keep them healthy Helps support your vascular (arteries and veins) system Supports your healthy heart Supports your memory function Supports your overall immune system Provides you powerful antioxidant benefits But keep in mind, without stable and pure production of this nutrient built into this Vitamin K2 formula, your benefits could be reduced. Don't just settle for any vitamin K or K2 supplement. Do like I do... demand the absolute best you can find.
