D3 10,000 + K by OTS is packed with 10,000 IU of vitamin D3 (cholecalciferol) and contains the most bioavailable and bioactive form of supplemental vitamin K2 available. The D3 in this supplement is identical to vitamin D derived in the body and synthesized by sunlight on the skin. D3 10,000 + K also may support bone health, cardiovascular health, and healthy blood clotting.
New research is focusing on bone and cardiovascular health benefits from the synergistic relationship between vitamin K2 and vitamin D3. Vitamin K is a group of structurally similar, naturally occurring fat-soluble vitamins essential to proper calcium utilization. Vitamin K activates the protein osteocalcin to help bind recently absorbed calcium to the bone's mineral matrix. Vitamin K has been found to help maintain bone mineral density by decreasing the activity of cells that break down the bone matrix. While vitamin D and vitamin K share similar qualities, they also act synergistically to support healthy blood circulation, boost immune function, and promote bone health and proper storage of calcium.
While most people consume adequate dietary vitamin K to maintain sufficient blood clotting, many do not consume enough to meet cardiovascular and bone health needs. Because of this, many people find supplementation to be very beneficial. Poor intestinal absorption and drug induced nutrient depletions can also lead to insufficient K2 levels. This leaves calcium available to be exported out of bone and into other tissues. A few medications that can cause depletion and deficiency of vitamin K are antibiotics, cholesterol-lowering medications, and laxatives.
