What is Vitamin K?
Vitamin K is a fat-soluble vitamin most commonly found in the diet as Vitamin K1 (plant foods like leafy green vegetables and dark berries) and Vitamin K2 (fermented foods and animal products). The body can only store a limited amount of Vitamin K, so it recycles the vitamin to reuse it several times.
Who should take Vitamin K?
People who don’t consume a lot of green leafy vegetables might not be getting enough vitamin K through their diet. If you take a blood clotting medication like warfarin, it’s important to keep your vitamin K intake consistent, so a supplement may help.
