Product insights

  • Thorne Vitamin K provides a comprehensive blend of vitamin K1 and two forms of vitamin K2 (MK-4 and MK-7), ensuring optimal absorption and utilization in the body.
  • Vitamin K1 primarily supports healthy blood clotting by acting as a cofactor for enzymes involved in the synthesis of coagulation factors.
  • Vitamin K2, particularly MK-4, plays a crucial role in bone health by activating osteocalcin, a protein that helps bind calcium to bones, while MK-7 has a longer half-life, providing sustained benefits.
  • The inclusion of MenaQ7, a well-researched form of MK-7, ensures that Thorne Vitamin K delivers consistent and reliable results, as demonstrated in numerous clinical studies.
