Vitamin K2 MK4 vs MK7: Key Differences

MK-7 (menaquinone-7) is long-acting, remaining active for up to 24 hours. Combining both provides comprehensive coverage.

What is Vitamin K2?

Vitamin K2, also known as menaquinone, is a fat-soluble vitamin essential for activating proteins that regulate calcium deposition. Unlike Vitamin K1 (phylloquinone), which is primarily involved in blood clotting, K2 directs calcium to bones and teeth while preventing arterial calcification. This unique role makes Vitamin K2 critical for long-term skeletal and cardiovascular health.

Health Benefits of Vitamin K2

Bone Health: Vitamin K2 activates osteocalcin, a protein that binds calcium to the bone matrix. Studies show that adequate K2 intake may help maintain bone density as we age. Arterial Health: K2 activates matrix Gla-protein (MGP), which inhibits calcium buildup in arteries, supporting normal arterial flexibility and healthy circulation. Synergy with Vitamin D: Vitamin D enhances calcium absorption, while K2 ensures it is deposited properly—making the pair vital for anyone supplementing calcium or Vitamin D.
