The Claim

In post-menopausal women with elevated dp-ucMGP, daily supplementation with 180 µg menaquinone-7 for one year significantly reduces brachial and carotid artery blood pressure by approximately 3–4.5% compared to placebo, with the greatest reductions occurring in individuals with the highest baseline arterial stiffness.

Cause and effect
1 study reviewed
In plain English

In post-menopausal women with high levels of dp-ucMGP, taking 180 micrograms of menaquinone-7 daily for one year lowers blood pressure in the arm and neck arteries by 3–4.5% compared to a placebo, with the largest drops seen in those with the stiffest arteries at the start.

See the scientific wording

In post-menopausal women with elevated dp-ucMGP, daily 180 µg menaquinone-7 supplementation for one year significantly lowers brachial and carotid artery blood pressure by approximately 3–4.5% compared to placebo, with the greatest reductions observed in those with the highest baseline arterial stiffness.

Why this might work

Vitamin K2 activates a protein that binds calcium in artery walls, preventing calcium buildup that stiffens arteries; softer arteries allow blood to flow more easily, which lowers blood pressure.

  1. Study: Beneficial effects of one-year menaquinone-7 supplementation on vascular stiffness and blood pressure in post-menopausal women

    In women after menopause with stiff arteries, taking a daily vitamin K2 supplement for a year slightly lowered their blood pressure, especially in those whose arteries were already the stiffest. The study proves it works.
