Vitamin D-3 25,000 IU with Vitamin K2 MK-7
High-potency support for bone, cardiovascular, and immune health.*
What It Does
This formula combines a clinically relevant dose of vitamin D3 with vitamin K2 (MK-7) to promote optimal calcium utilization, supporting healthy bones, heart function, and immune balance.* The nutrients work together to help direct calcium to bones and teeth while maintaining vascular integrity and balanced cytokine signaling.*
How It Works
Vitamin D3 (25,000 IU as Cholecalciferol): Supports calcium and phosphorus absorption for bone mineralization, immune modulation, and musculoskeletal strength.* [1,3] Vitamin D is labeled as both activity (25,000 IU) and mass (625 mcg).
Vitamin K2 (as MK-7, 45 mcg): Activates osteocalcin and matrix Gla protein to help guide calcium to bone and away from soft tissues, supporting cardiovascular elasticity and arterial health.* [2,4]
Dual-Action Formula: The combination of D3 and K2 helps maintain the balance between bone density and vascular integrity, optimizing overall calcium homeostasis.* [2,4]
Who It’s For
Ideal for adults seeking high-potency vitamin D3 support under healthcare practitioner supervision, particularly those with limited sun exposure, higher nutrient requirements, or targeted bone and cardiovascular health goals.*
