D3+K2 Cofactor Complex provides 10,000 IU of vitamin D3 (as cholecalciferol) and vitamin K2 (as MK-7), along with important cofactors zinc and boron to help support optimal bone and heart health, and to maintain proper immune system balance. D3+K2 Cofactor Complex contains precisely designed ingredients to optimize Vitamin D usage. A genetic mutation (SNP) on the VDR Taq gene may impede vitamin D from fully functioning. Subsequently, this formula includes vitaMK7®, a patented, natural K2 vitamin that works with vitamin D to enhance the body's utilization of calcium in the bloodstream. In clinical studies, vitaMK7® increased osteocalcin (calcium-binding protein) levels, strengthening the body's ability to utilize calcium in the bloodstream and prevent bone loss. Benefits of D3+K2 Cofactor Complex may include: Improved Inflammation Control* Healthy blood circulation* Enhanced bone health and proper calcium storage* Improved cardiovascular health and calcium delivery* Improved immune function* 60 Capsules (formally called Maximum Vitamin D3+K2)
