Carlson Labs Kid's Super Daily K2 Liquid for Healthy Bones is an enhanced, bioactive form of vitamin K that has superior retention in the body. Without vitamin K2, calcium canŐt adequately be processed in our body to help maintain strong, healthy bones. Vitamin K2 activates certain proteins, including osteocalcin and Matrix GLA Protein (MGP), which play a role in binding calcium to the bone matrix. Without an adequate amount of vitamin K2, a significant amount of osteocalcin will remain inactive and unable to bind calcium. Vitamin K2 as MK-7 also supports cardiovascular system health by promoting healthy blood clotting and directing calcium out of the bloodstream and arteries and into the bones.
