🫀 Vitamin K2 (MK-7) in the Prevention of Vascular Calcification: Rotterdam Study

How vitamin K2 supports vessel health

Vitamin K2 (MK-7) is studied for protecting vessels from calcification. Rotterdam Study data link it to better heart health. Let's look at it in detail.

🔬 What is vitamin K2

Vitamin K2 (menaquinone) supports blood clotting and directs calcium into bones, not vessels. There are several forms, including MK-7.

  • Menaquinone.
  • Blood clotting.
  • Directs calcium to bones.
  • Forms MK-4, MK-7.
Why it matters: K2 affects heart and bone health.

🧬 The MK-7 form

MK-7 is a vitamin K2 form with a long chain that stays longer in the blood. It is considered most effective for vessel support.

  • Long chain.
  • Stays longer in blood.
  • Effective for vessels.
  • Source — natto.
Data: MK-7 is often studied for heart and bones.

🫀 Vascular calcification

Vascular calcification is calcium deposition in artery walls, raising cardiovascular risk. Vitamin K2 may reduce this process.

  • Calcium deposition.
  • Raises disease risk.
  • K2 reduces the process.
  • Linked to atherosclerosis.

📊 Rotterdam Study

Rotterdam Study is a large population study. It showed a link between high vitamin K2 intake and lower risk of calcification and heart disease.

  • Large study.
  • K2 intake.
  • Lower calcification.
  • Less heart disease.
Important: the link is promising, but clinical confirmation is needed.

⚙️ Mechanism

Vitamin K2 activates proteins (MGP, osteocalcin) that direct calcium into bones and prevent its deposition in vessels.

  • Activates MGP.
  • Directs calcium.
  • Protects vessels.
  • Supports bones.
Data: K2 works through calcium-regulating proteins.

📊 Dosages

GoalDosage
Support45–100 mcg/day
Prevention100–200 mcg/day
Important: often combined with vitamin D3.

💡 Practice

  • MK-7 100 mcg/day for support.
  • Combine with vitamin D3.
  • Eat natto and fermented foods.
  • Control blood pressure and cholesterol.
  • Diet and movement.
  • Consult a doctor.
Tip: with anticoagulants, check with a doctor.
