What Foods are High in Vitamin K?

If you're looking to maintain bone health and support healthy blood clotting, vitamin K is an essential nutrient to consider. This fat-soluble vitamin plays a vital role in various bodily functions, and it's important to consume enough of it in your diet. Fortunately, it's easy to boost your intake, as there are plenty of delicious foods that are high in vitamin K! In this article we'll share some of the top food sources and ways you can easily incorporate them into your diet.

What is vitamin K2?

Vitamin K2 is a nutrient that plays a vital role in bone health by regulating calcium metabolism. Vitamin K2 is mainly found in animal-based products like grass-fed whey and dairy, as well as in fermented foods.

On the other hand, vitamin K1 is primarily found in leafy green vegetables, and is used to activate blood clotting factors. Additionally, vitamin K2 has a longer half-life in the body than vitamin K1, meaning it stays in the bloodstream for longer periods, allowing it to exert its beneficial effects.

What are the health benefits of vitamin K2?

Vitamin K2 is essential for regulating our intake of calcium by ensuring it’s directed to the bones, where it is needed, rather than accumulating in soft tissues and arteries, which can cause harm. By maintaining calcium balance, K2 can help promote cardiovascular health, as well as promoting bone health.

Therefore, it’s essential to consume vitamin K2 directly from food sources or supplements. Vitamin K2 supplements are available alone or combined with other synergistic nutrients, such as calcium in certain multivitamins, or in some prenatal supplements.

The recommendations for vitamin K intake are outlined below:

• Adult men: 120 mcg/day
• Adult women: 90 mcg/day
• Pregnant women: 90 mcg/day
• Breastfeeding women: 90 mcg/day
