MK-7 is a form of vitamin K2, which is necessary for the activation of osteocalcin, a protein that transports and integrates calcium into bone to ensure a healthy skeleton. Incorporating calcium into the bone matrix means that less calcium is available for harmful deposits in soft body tissues. Recent studies suggest that dietary intakes of vitamin K2 among the general population are inadequate, and that vitamin K2 supplementation may improve bone strength and reduce the healthcare costs associated with osteoporosis.
