The Claim
Daily supplementation with 45 μg of menaquinone-7 for 8 weeks increases serum concentrations of MK-7 in healthy prepubertal children and does not alter coagulation parameters or bone turnover markers.
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.
Taking 45 micrograms of menaquinone-7 daily for 8 weeks raises levels of MK-7 in the blood of healthy children who have not yet reached puberty, without changing blood clotting measures or bone metabolism markers.
See the scientific wording
Daily supplementation with 45 μg of menaquinone-7 for 8 weeks significantly increases serum concentrations of MK-7 in healthy prepubertal children, confirming bioavailability and compliance, without affecting coagulation parameters or bone turnover markers.
When a child takes a daily vitamin K2 pill, the vitamin gets absorbed from the gut into the blood, raising its concentration in the bloodstream. This vitamin then helps a liver enzyme activate a bone protein so it can bind to minerals in bone tissue. The activated protein improves bone health, but the vitamin does not change how blood clots or how fast bone breaks down and rebuilds.
What the research says
1 studyKids who took a daily vitamin K2 pill for two months had more K2 in their blood, and their blood clotting and bone growth stayed the same — just like the claim said.
