Verifiable Science

Provides a blend of vitamin K1 , vitamin K2 (MK-4), vitamin K2 (MK-7), and vitamin D to 
This specific nutrient stack—combining Vitamin D3 with all three main forms of Vitamin K (K1, K2 MK-4, and K2 MK-7)—is designed to create a synergistic system for bone strength, cardiovascular protection, and calcium management.

By providing both standard and long-acting forms of Vitamin K alongside Vitamin D3, this blend ensures calcium is directed into bones and teeth rather than accumulating in arteries or soft tissues.

Key Benefits of This Synergy

1. Bone Density and Skeletal Strength

  • Vitamin D3 (25 mcg / 1,000 IU): Increases intestinal absorption of calcium into the bloodstream.
  • Vitamin K2 (MK-4 & MK-7): Activates osteocalcin, a key protein that binds calcium directly into the bone matrix, reinforcing bone mineral density.
  • The Synergy: D3 brings the calcium into the body, while K2 makes sure that calcium is actually deposited into the bones.
2. Cardiovascular and Arterial Protection ("The Calcium Steering Wheel")

  • Preventing Soft Tissue Calcification: Without sufficient Vitamin K, absorbed calcium can collect in arterial walls, leading to stiffness or plaque buildup.
  • Activating Matrix Gla Protein (MGP): Both MK-4 and MK-7 activate MGP, an enzyme that inhibits vascular calcification, preserving elasticity in blood vessels and supporting healthy arterial function.
3. Liver, Blood Clotting, and Tissue Distribution

  • Vitamin K1 (500 mcg): Primarily targets the liver, where it activates proteins essential for healthy, normal blood clotting.
  • Vitamin K2 MK-4 (1,000 mcg): Quickly absorbed and distributed to peripheral tissues outside the liver, including the brain, pancreas, and reproductive organs.
  • Vitamin K2 MK-7 (45 mcg): Features a long biological half-life, staying active in the bloodstream for days to provide continuous activation of K-dependent proteins between doses.
4. Immune and Cellular Support

  • Vitamin D3: Regulates immune cell function, supporting both innate and adaptive immune defenses.
