The Claim

Supplementation with 45 μg of menaquinone-7 for 8 weeks has no effect on bone turnover markers (bone alkaline phosphatase or NTX) or coagulation parameters (thrombin peak height or endogenous thrombin potential) in healthy prepubertal children.

Description
1 study reviewed
In plain English

Giving 45 micrograms of menaquinone-7 daily for 8 weeks does not change levels of bone turnover markers or blood clotting parameters in healthy children who have not yet reached puberty.

See the scientific wording

Supplementation with 45 μg of menaquinone-7 for 8 weeks does not alter bone turnover markers (bone alkaline phosphatase or NTX) or coagulation parameters (thrombin peak height or endogenous thrombin potential) in healthy prepubertal children, indicating no detectable effect on bone remodeling or hemostasis.

Why this might work

A daily vitamin K2 supplement gets absorbed into the blood and helps change a bone protein so it can bind to minerals in bone, but this change does not speed up or slow down bone building or breakdown, and it does not affect how blood clots.

  1. Study: The effect of menaquinone-7 (vitamin K2) supplementation on osteocalcin carboxylation in healthy prepubertal children

    Kids who took a daily vitamin K2 pill for two months didn't show any change in how fast their bones grew or how their blood clotted — even though their bodies used the vitamin better. So the pill didn't hurt or help those processes.
