Free, embeddable tools and data references for understanding grayanotoxin (GTX) levels in mad honey. Educational only: not medical or safety advice.
Grayanotoxin Dose Calculator
Enter a concentration and serving size to calculate the total GTX dose, see which risk band it falls in, and compare it to the EFSA reference point.
- Inputs: concentration (mg/kg), serving size (g), body weight (kg)
- Outputs: total dose in mg, risk band, and % of EFSA reference point
- Live marker on a color-coded Trace / Low / Moderate / High scale
Reported Grayanotoxin Concentrations
Laboratory-measured GTX I and III ranges from real mad honey samples, plotted against the risk bands. Shows how unpredictably potency varies batch to batch.
- GTX I: 0.75 to 64.86 mg/kg; GTX III: 0.25 to 63.99 mg/kg (Ahn et al., 2022, Nepal)
- Close to 90-fold spread between the weakest and strongest positive samples
- Bar chart, data table, and EFSA context all on one page
Both tools are freely embeddable via iframe. Each page includes copy-paste embed code. Educational use only: the EFSA found no grayanotoxin intake level to be safe for all individuals.
