A meta-analysis found vitamin K intake linked to a 17% lower fracture risk — but the confidence interval crossed 1.0, meaning the result wasn't statistically significant.

This early meta-analysis doesn't confirm the popular belief that vitamin K protects bones; the null result and lack of effect on hip fractures mean the picture is still contested, not settled.

Researchers pooled data on dietary vitamin K and fracture risk and saw a trend toward fewer fractures (risk ratio 0.83), but the 95% confidence interval (0.68–1.01) includes 1.0, so the finding could be due to chance. The same analysis found no significant effect on hip fractures, and because this is among the first large-scale studies on the topic, the evidence remains too weak to support a bone-protective claim.

Where this fits in the evidence

This is among the first studies we've indexed on Vitamin K for Reduced Fracture Risk — treat it as an early signal until more research accumulates.
