If you organized a vitamin popularity contest, commonly known nutrients like vitamin C would easily sweep the competition. But once you move beyond the initial letters in the alphabet (think: vitamin A, vitamin B, vitamin D3), you’ll discover there are other letter vitamins worth knowing.
What Is Vitamin K?
When you see the term “vitamin K” it actually covers a family of compounds that include phylloquinone (vitamin K1) and a series of menaquinones (vitamin K2). According to the National Institutes of Health, vitamin K “functions as a coenzyme for vitamin K-dependent carboxylase, an enzyme required for the synthesis of proteins involved in hemostasis (blood clotting) and bone metabolism, and other diverse physiological functions.”
Here are some of the foods that contain the most amounts of vitamin K:
- Collards
- Turnip greens
- Spinach
- Kale
- Carrot juice
- Canned pumpkin
- Okra
- Pine nuts
- Chicken
