What Is Vitamin K?
First discovered in 1929, vitamin K is an important substance needed for bone health, heart health, and blood clotting. It is divided into two main types:
– Vitamin K1, also known as phylloquinone: Can be found in plant-based foods, such as leafy green vegetables
– Vitamin K2, also known as menaquinone: Can be found in fermented foods and animal-based foods
There are some different subtypes of vitamin K2. The most important forms include MK-7 and MK-4. [1]
