An intake of up to 400mg of caffeine appears to be safe for most healthy adults.1 That is approximately 4 cups of brewed coffee or 10 cups of brewed black tea.2 It's important to know your portions because heavy use of caffeine may lead to unpleasant side effects, especially if you're sensitive. Some examples of these side effects are headaches, insomnia, nervousness, irritability, increased heart rate, and frequent urination.1
The main take home message today is to be aware of your daily caffeine consumption and adjust your intake depending on your body's sensitivity to caffeine.
