Vitamin K is just as important as other vitamins, even though it may not always get as much attention. It is necessary for bone health, proper blood clotting, and more. If you are not getting enough from the foods you eat, or you are having trouble absorbing it, a supplement, such as the Vitamin D3 with K2 Patch by PatchAid, can provide additional amounts of vitamin K.* Be sure to talk to your healthcare provider before taking any nutritional supplement.
