Osteo-MK4 by NBI combines menaquinone-4 (MK-4), the bioactive form of vitamin K2, with vitamin D3 to support bone mineral density, calcium utilization, and skeletal integrity. MK-4 specifically activates osteocalcin, a protein that helps direct calcium into bone tissue rather than soft tissues. This formulation is designed for adults seeking targeted bone health support, particularly those with concerns about long-term skeletal maintenance.Why It's Worth Considering: MK-4 is the form most studied in bone metabolism research and is used here alongside D3, which works synergistically to support calcium absorption and proper bone remodeling.
