New research is focusing on the synergistic relationship between vitamin K2 and vitamin D3, for bone and cardiovascular health.1 A group of naturally occurring and structurally similar, fat-soluble vitamins, vitamin K is essential for the proper utilization of calcium. Through its activation of the protein osteocalcin, vitamin K helps to bind newly absorbed calcium to the mineral matrix in bone. In addition, vitamin K has been found to help maintain bone mineral density by decreasing the activity of osteoclasts, a cell that breaks down the bone matrix.2 Vitamin K also provides critical cardiovascular protection by helping to activate matrix Gla protein (MGP), an inhibitor of circulatory calcification.3, 4 Thus, vitamin K and vitamin D not only share similar qualities but they also act synergistically with one another within the body.5 Liquid Vitamin D3 with K2 utilizes a medium chain triglyceride (MCT) delivery system providing 10 mcg of MenaQ7® PRO, the most widely studied form of vitamin K2 as MK-7, and 1,000 IU of vitamin D3 per serving. Natural medium-chain triglycerides have unique physical properties that allow them to be readily absorbed without additional emulsifying agents. MCTs are a great way to deliver pure, tasteless and odorless liquid vitamin K2 and D3 that combine easily with any beverage.
