Study snapshot

DesignAcute dose-ranging animal toxicology study
ModelSwiss mice
SampleMultiple control and dose groups; exact total N was not stated in the PubMed abstract.
InterventionIntraperitoneal apigenin at 25, 50, 100 or 200 mg/kg

What the study showed, in plain terms

This animal toxicology study tested high intraperitoneal doses of apigenin to look for dose-related liver injury signals.

Key findings

At 100 and 200 mg/kg, mice showed increased liver enzymes, oxidative-stress markers and histologic liver damage, with gene-expression changes involving oxidative stress and apoptosis. Lower tested doses showed less severe findings.

What this study can and cannot tell us

Apigenin was injected intraperitoneally at doses far above ordinary oral supplement exposure on a body-weight basis. The study identifies a high-dose animal toxicity signal but cannot define a safe or harmful human oral dose.
