What is Vitamin K?
Vitamin K is a fat-soluble vitamin that our body needs to perform various important functions. It is also known as the clotting vitamin. Our body needs this vitamin to make certain proteins (clotting factors like II, VII, IX, and X) in the liver that are responsible for blood clotting. There are two main types of vitamin K. They are:
- Vitamin K1 (Phylloquinone): Found in plant-based foods like green leafy vegetables.
- Vitamin K2 (Menaquinone): Found in animal-based and fermented products.
Both forms of this vitamin help our body in unique ways and ensure that everything functions smoothly.

Vitamin K is vital for processes like blood clotting and bone health. Without enough vitamin K, even a minor scratch can cause excess bleeding. Additionally, it also supports calcium regulation in the bones and reduces the risk of osteoporosis (a condition that weakens bone).
