PhytonadioneVitamin K1

Ingredient Type: Vitamin

Phytonadione, also known as Vitamin K1, is a fat-soluble vitamin that is essential for blood clotting and bone health. It is found naturally in green leafy vegetables such as spinach, kale, and broccoli. In protein powders, phytonadione is often added to provide a source of vitamin K to support bone health and to ensure that the body has adequate levels for proper blood clotting.

Vitamin K plays a critical role in activating the proteins responsible for blood clotting, which helps stop bleeding after an injury. It also helps maintain healthy bones by supporting the production of osteocalcin, a protein needed for bone mineralization.

Phytonadione is considered safe when taken in appropriate amounts.
