The LD50 (median lethal dose) of caffeine is generally estimated to be between 150 and 200 mg per kilogram of body weight. However, some case reports have indicated lethal effects at doses as low as 57 mg/kg. A toxic dose of caffeine, leading to adverse effects like tachycardia, arrhythmia, and seizures, is estimated to be around 1.2 grams. Lethal doses of caffeine, reported in some studies, have been found at blood concentrations of 80 to 100 g/mL, which can result from ingesting approximately 10 grams or more of caffeine.
