Vitamin D and vitamin K2 work together to help the body manage calcium properly. Vitamin D increases calcium absorption and supports the production of important proteins involved in bone health. However, it does not control where calcium goes. That is where vitamin K2 becomes important. Vitamin K2 activates key proteins that help move calcium into bones and keep it away from arteries and other soft tissues. This teamwork supports strong bones, healthy calcium balance, and cardiovascular health. Vitamin D helps provide the calcium and build the tools needed to use it, while vitamin K2 switches those tools on. Together, they create a more complete system for skeletal support, better calcium use, and long-term health than vitamin D alone, especially for bone strength and vascular support.
