What is Vitamin K?
Vitamin K is a fat-soluble vitamin that plays a central role in the body's natural processes. It exists in two main forms: K1 (phylloquinone), primarily found in green leafy vegetables, and K2 (menaquinone), produced by gut bacteria and found in certain fermented foods. Vitamin K is important for normal bodily function and aids several biological processes. As a supplement, vitamin K is offered to complement a varied diet and ensure adequate intake, especially for those with increased needs or limited dietary variety.
