Health Benefits

  • Optimal Bone Health

    Vitamin D3 + K2 promotes proper bone mineralization by directing calcium to where it's needed most. While vitamin D3 enhances calcium absorption, vitamin K2 activates osteocalcin, the protein responsible for binding calcium to the bone matrix. This combination helps maintain bone mineral density and supports overall skeletal strength more effectively than either nutrient alone.

  • Cardiovascular Health

    This powerful combination supports heart and circulatory health by helping prevent calcium deposits in arteries and soft tissues. Vitamin K2 activates matrix Gla protein (MGP), which inhibits arterial calcification, while supporting proper calcium utilization. Studies show that individuals with higher K2 intake demonstrate significantly better cardiovascular health markers compared to those with lower intake.

  • Immune Function

    Vitamin D3 + K2 provides crucial support for balanced immune response and overall immune system strength. Research from the Framingham Offspring Study demonstrates that higher serum levels of both vitamins D and K are associated with stronger immune function and balanced inflammatory responses, making this combination essential for comprehensive immune support.
