Caffeine Overdose Calculator

Caffeine Overdose Calculator

Caffeine Overdose Calculator


Some days require a lot more energy than others. On those challenging days, you might find yourself reaching for multiple coffees and energy drinks to keep you going. But how much caffeine is too much in a single day?  

Unfortunately there isn’t a single answer that applies to everyone. That’s why we created an easy to use caffeine overdose calculator that can help give you an understanding of where your limit might be.  

This calculator uses the latest recommendations from the FDA to give its best guess, but we always recommend you consult your doctor if you’re at all concerned about caffeine related health concerns.

What are the symptoms of a caffeine overdose?

Caffeine overdose symptoms can range from unpleasant to downright miserable. That’s why it’s very important to understand how much is too much.

The most common symptoms are dizziness, headache, irritability, and insomnia. These can range from mild to severe and any one of them can ruin your day by itself.  

But if you’ve really gone overboard with the caffeine, you might experience some downright nasty side effects. These might include: trouble breathing, vomiting, hallucinations, chest pain, and convulsions.

It’s very important to seek medical attention if any of these occur.  



If used wisely, caffeine can be a big help for focus and energy throughout a busy day. And if you’re looking to help smooth over one of the most common side effects, the caffeine jitters, we recommend you try an energy drink with a solid dose of L-Theanine.

L-Theanine helps regulate the blood pressure raising effects of caffeine which is the main cause of the jitters. That’s why we put 15x the L-theanine of a cup of green tea into our Proper Wild Clean All Day Energy Shots to deliver you energy and focus without the junk.
