This product from Natural Factors contains MK-7 which is derived naturally from natto beans and is one of the most bioavailable forms of vitamin K out there . Each dose directs calcium towards the bones and teeth where it is needed most and sends it away from the arteries where it causes damage. This encourages stronger teeth, it increases calcium absorption and it prevents vitamin K deficiency too.
Each vegetarian capsule contains:
Vitamin K2 (menaquinone-7) (MK-7) (natto bean) 100 mcg
Microcrystalline cellulose, vegetarian capsule (carbohydrate gum [cellulose], purified water), vegetable grade magnesium stearate (lubricant).
