Eating vitamin K foods is quite easy, and important for people with some health conditions or a deficiency in this nutrient.
What is Vitamin K?
Vitamin K is a water-soluble vitamin that comes in two main forms, K1 and K2. The bacteria in our gut are able to convert vitamin K1 into vitamin K2, which can then be used by the body in a variety of ways. Vitamin K1 is found most commonly in green leafy vegetables, although there are plenty of other dietary sources.
Vitamin K has an impressive list of health benefits which include:
- Boosting bone density
- Protecting against osteoporosis
- Maintaining cardiovascular health
