The Claim
Menaquinone-7 supplementation in post-menopausal women leads to greater improvements in arterial distensibility and compliance coefficients among individuals with a baseline b-stiffness index above the median compared to those with a baseline b-stiffness index at or below the median.
What the research says
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 post-menopausal women, taking menaquinone-7 supplements results in larger improvements in arterial flexibility for those who start with higher arterial stiffness, as measured by the b-stiffness index.
See the scientific wording
The vascular benefits of menaquinone-7 supplementation in post-menopausal women are most pronounced in those with the highest baseline arterial stiffness, as shown by greater improvements in distensibility and compliance coefficients among women with a b-stiffness index above the median.
Menaquinone-7 activates a protein that stops calcium from building up in artery walls. When calcium is blocked from depositing, the arteries stay flexible and can expand and contract normally, especially in people whose arteries were already stiff.
What the research says
1 studyWomen with stiffer arteries at the start of the study saw the biggest improvement in artery flexibility after taking MK-7 for a year, while those with less stiff arteries didn’t improve as much.
