Important Disclaimer

This calculator is for educational purposes only. The lethal dose calculations are based on scientific estimates (LD50 of 150 mg/kg body weight) but individual tolerance varies significantly.

The FDA recommends healthy adults limit caffeine intake to 400mg per day. Excessive caffeine consumption can cause serious health issues including rapid heartbeat, anxiety, insomnia, and in extreme cases, death.

Always consume caffeine responsibly and consult a healthcare provider if you have concerns about your caffeine intake.
