The Benefits of Vitamin K2 MK7: A Comprehensive Guide

Vitamin K2 MK7 is gaining significant attention in the health and wellness community for its wide range of benefits, particularly related to cardiovascular and bone health. As a potent form of Vitamin K2, MK7 (menaquinone-7) is a highly bioavailable and longer-lasting variant compared to its counterparts. This article explores the various health benefits of Vitamin K2 MK7, its sources, and how it compares to other forms of Vitamin K.

Understanding Vitamin K2 MK7

Vitamin K2 is part of the Vitamin K family, which includes K1 (phylloquinone) and K2 (menaquinones). While K1 is primarily involved in blood clotting, K2 plays a crucial role in calcium metabolism. MK7, a subtype of K2, is known for its superior absorption and longer half-life in the bloodstream.

Health Benefits of Vitamin K2 MK7

Vitamin K2 MK7 offers numerous health benefits, particularly in the areas of bone and cardiovascular health:

Bone Health

Vitamin K2 MK7 is essential for activating osteocalcin, a protein that binds calcium to bones, enhancing bone mineralization and strength. This reduces the risk of fractures and osteoporosis, especially in postmenopausal women.

Cardiovascular Health

K2 MK7 helps prevent arterial calcification by activating matrix Gla-protein (MGP), which inhibits calcium deposits in arteries. This action supports cardiovascular health by maintaining arterial flexibility and reducing the risk of atherosclerosis.

Other Benefits

Emerging research suggests that Vitamin K2 MK7 may also play a role in improving insulin sensitivity, reducing inflammation, and potentially aiding in cancer prevention.

Sources of Vitamin K2 MK7

Vitamin K2 MK7 is predominantly found in fermented foods. The richest sources include natto (fermented soybeans), cheese, and sauerkraut. Supplements are also available, providing a convenient way to ensure adequate intake.

Incorporating Vitamin K2 MK7 into Your Diet

To enhance your intake of Vitamin K2 MK7, consider adding the following to your diet:

  • Natto
  • Cheese, particularly Gouda and Brie
  • Fermented vegetables like sauerkraut
  • Supplements, especially those combining Vitamin D and K2 for synergistic effects


Vitamin K2 MK7 stands out as a vital nutrient for maintaining bone and cardiovascular health. Its superior bioavailability and longer half-life make it an effective form of Vitamin K2. Incorporating MK7-rich foods or supplements into your diet can provide significant health benefits, supporting overall well-being.
