Caffeine Calculator

Caffeine has its benefits, but it can also be dangerous and unhealthy. Most adults can safely consume up to 400 mg of caffeine per day, but there is a daily limit to how much caffeine you can intake before it will kill you. While we don’t recommend you experimenting to find out with trial and error, caffeine overdose is real and often the result of consuming too many energy drinks or supplements in a short period of time.

Although it can be hard to ingest a lethal dose of caffeine, kids and people with health conditions can be at-risk. For instance, too much caffeine can kill you by raising your blood pressure, elevating your heart rate, shrinking your blood vessels and ultimately causing a cardiac event, stroke, or other cardio-vascular issue.

To help you avoid death by caffeine, we’ve used the latest research to calculate the amount of caffeine you can drink. This caffeine calculator shows how much of a caffeinated drink is safe for consumption and how much could be deadly based on a person’s body weight. Check out how Red Bulls, 5 Hour Energy Shots, Bangs or Monsters you can drink in a day to maintain your health!
