The Claim

Daily supplementation with 180 µg of menaquinone-7 for one year reduces plasma levels of dephosphorylated-undercarboxylated matrix Gla protein (dp-ucMGP) by 13.4% in post-menopausal women.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

In plain English

Taking 180 micrograms of menaquinone-7 every day for one year lowers the level of dephosphorylated-undercarboxylated matrix Gla protein in the blood by 13.4% in post-menopausal women.

See the scientific wording

Daily 180 µg menaquinone-7 supplementation for one year significantly reduces plasma levels of dephosphorylated-undercarboxylated matrix Gla protein (dp-ucMGP) by 13.4% in post-menopausal women, indicating enhanced activation of this vascular protective protein.

Why this might work

Vitamin K2 from the supplement activates a protein in blood vessel walls that grabs calcium and stops it from building up in the arteries. This keeps the arteries flexible and prevents them from hardening.

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

    Taking a daily vitamin K2 supplement (180 micrograms) for a year lowered a specific blood marker linked to stiff arteries by 13.4% in post-menopausal women, meaning their bodies became better at activating a protein that protects their blood vessels.
