🫀 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.
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.
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.
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.
Dosages
| Goal | Dosage |
|---|---|
| Support | 45–100 mcg/day |
| Prevention | 100–200 mcg/day |
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.
