D3-K2 pairs high-dose vitamin D3 (cholecalciferol) with vitamin K2 as menaquinone-7, a highly bioavailable form that works synergistically to support bone density, cardiovascular health, and immune function.

While vitamin D3 promotes calcium absorption, vitamin K2 ensures that calcium is deposited in bones rather than soft tissues like arteries.

This targeted calcium management supports both skeletal strength and vascular health, making it essential for anyone taking higher doses of vitamin D.
