How to Increase Your Vitamin K Intake Naturally

Introduction to Vitamin K

Vitamin K is an essential nutrient that plays a crucial role in blood clotting and bone health. It exists in two primary forms: Vitamin K1 (phylloquinone) and Vitamin K2 (menaquinones). While K1 is found abundantly in leafy greens, K2 is synthesized by bacteria and found in fermented foods and animal products.
