The Synergy of Vitamin D3 and K2 Benefits 

How Vitamin D3 and K2 Work Together 

• Vitamin D3 enhances calcium absorption in the gut, ensuring your body has enough of this essential mineral.

• Vitamin K2 activates proteins like osteocalcin and matrix Gla-protein, which direct calcium to bones and teeth while preventing it from settling in arteries.

• Together, they create a balanced system that promotes bone health and cardiovascular wellness. 

Studies have shown that combining vitamin D3 and K2 improves calcium metabolism more effectively than taking either nutrient alone.
