This calculator makes it easy to keep an eye on how much caffeine you are consuming daily, helping you determine when to reduce or increase consumption as per your body weight and tolerance level. Typically, an adult’s upper limit for safe caffeine consumption should not exceed 400 mg daily, equivalent to approximately three or four cups of regular coffee or tea; this may differ depending on their body mass index (BMI) and tolerance level.

Caffeine is a stimulant and excessive consumption may result in adverse side effects, including tremors, anxiety, upset stomach, fast heartbeat and insomnia. Although caffeine has health benefits such as antioxidants and reduced risk of cardiovascular disease, excessive consumption could negate those benefits; the FDA advises limiting daily caffeine consumption to no more than 400mg daily for pregnant women or people with certain medical conditions; pregnant women or other individuals may require reduced amounts of caffeine consumption than other individuals.

Our caffeine calculator can help you stay on top of your caffeine consumption by showing the amounts found in drinks, food and pre-workout supplements. Furthermore, it will show how your consumption compares with recommended daily allowances for adults so you can make adjustments that get the most from coffee without adverse side effects.

Utilizing our caffeine calculator is simple. Just enter all the food and beverages consumed during each day (including pre-workout supplements) into our calculator, select items containing caffeine and enter how many are consumed daily into our calculator, then the calculator will display how much caffeine your daily intake compares with FDA recommendations.

This caffeine calculator will not only assist with your morning cup of joe, but can be used for all of your favorite coffee and tea beverages as well as energy drinks, soft drinks, chocolate drinks and energy bars.
