1. What Is Vitamin K And Why Do We Need It?
Vitamin K is a fat-soluble vitamin crucial for blood clotting, bone metabolism, and heart health. According to a study published in the Journal of the American College of Nutrition, vitamin K is not just one compound but a group of compounds, with phylloquinone (K1) and menaquinones (K2) being the most significant. These forms ensure that our blood clots properly and our bones remain strong.
1.1. Understanding the Different Forms of Vitamin K
Vitamin K comes in several forms, each with a unique source and function:
- Vitamin K1 (Phylloquinone): Predominantly found in green leafy vegetables, K1 is essential for blood clotting.
- Vitamin K2 (Menaquinone): Found in animal products and fermented foods, K2 plays a vital role in bone health and cardiovascular function. Menaquinones are also produced by bacteria in the human gut.
- Vitamin K3 (Menadione): A synthetic form of vitamin K, typically used in animal feed.
1.2. Why Is Vitamin K Important for Blood Clotting?
Vitamin K is vital for synthesizing several proteins needed for blood clotting. It modifies these proteins, enabling them to bind calcium ions, essential for the clotting process.
