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 talk to your healthcare practitioner to see if vitamin K supplementation is right for you.

Explore expert answers to some of the most frequently asked vitamin K questions.

  • What does vitamin K do?

    Vitamin K2 aids in bone mineralization to help support strong bones when taken with calcium.
  • How much vitamin K should I take daily?

    Take one softgel daily with water and a meal.
  • Where does vitamin K come from?

    Vitamin K1 is derived from plants and is primarily found in the Western diet from green leafy vegetables such as spinach, kale and broccoli. In contrast, vitamin K2 is animal-derived and is found in small amounts from foods such as liver, certain cheeses, and other fermented foods, including natto food, made from fermented soybeans. Vitamin K2 can also be made by intestinal bacteria.
  • Are there any important drug interactions that I need to be aware of?

    Yes, there are certain blood thinning medications (e.g., Coumadin/Warfarin) that work by decreasing the activity of vitamin K-dependent blood clotting pathways in the body, thereby extending the time that is needed for a blood clot to form. Therefore, to help ensure that your prescribed blood thinner medications work effectively, it is important to maintain a consistent vitamin K intake. A sudden, significant decrease or increase in your vitamin K intake from food or supplements could amplify or reduce the efficacy of your blood thinner medication, respectively. This drug nutrient interaction information should be communicated to you by your healthcare professional, with specific guidance on maintaining consistent dietary intake of vitamin K.
