Vitamin K is a fat-soluble vitamin that plays a critical role in blood clotting and bone health. There are two primary forms of vitamin K: vitamin K1 (phylloquinone) and vitamin K2 (menaquinone).
- Vitamin K1 (Phylloquinone): Found primarily in leafy green vegetables, such as kale, spinach, and broccoli, as well as in some plant oils.
- Vitamin K2 (Menaquinone): Produced by bacteria in the human gut and is also found in certain animal-based foods, including meat, cheese, and fermented foods like natto (a Japanese soybean dish).
Vitamin K2 is further divided into several subtypes (MK-4 through MK-13), with MK-7 and MK-4 being the most well-studied. Vitamin K is an essential nutrient that plays a crucial role in bone health.
