4 Best Vitamin K Supplements

Do you know what vitamin K is? It is a fat soluble vitamin that is best known for its role in blood clotting.

However, it also plays an important role in bone health and has been shown to reduce the risk of cancer.

Foods that contain vitamin K include green leafy vegetables, meat and eggs. If you don’t eat many of these foods you may be deficient.

Deficiencies in various nutrients can contribute to out of control cravings for food, worse bone health and problems with blood clotting.

If you are looking for a good vitamin K supplement, then you have come to the right place!

In this blog post, we will discuss the best vitamin K supplements on the market and how they can benefit your health.

How We Rank and Review – 8 Criteria

  • At Eating Enlightenment we value quality over price. However, all else being equal, then price comes into consideration. 

2 – Reviews: How many reviews for each product? What’s the average rating? How many third party reviews?

  • We strongly believe in third party reviews. Many supplement companies list positive reviews on their website, but third party reviews include negative comments. We always go with third party reviews.

Are vitamin K1 and K2 the same?

Vitamin K are compounds. The most essential are vitamins K1 and K2.

  • Vitamin K1 is a vegetable derived from leafy greens which are great sources of iron.
  • Vitamin K2 is mainly produced from meat, cheese or eggs and can be synthesized through bacteria.

Vitamins K1 and K2 are similar because  they are both essential for blood clotting.

However, they have different functions. Vitamin K1 is different than K2 because it is mainly used for clotting, while secondary K proteins are responsible for calcium metabolism.

If you have low calcium, please see our calcium supplements list.

If you are concerned about Vitamin K, you may want to determine via quick blood test if you are deficient in Vitamin K levels.
