How many coffees a day?

The recommended daily intake of caffeine for healthy adults is up to 400 milligrams. This is equivalent to about four cups of brewed coffee, 10 cans of cola, or two energy drinks. However, individual sensitivity to caffeine can vary, so some people may experience negative effects, such as anxiety or insomnia, with a lower intake. In these cases, it is important to limit or avoid caffeine consumption.

Some factors that can affect your caffeine sensitivity include your age, weight, medical condition, and medications you are taking. People who are pregnant or breastfeeding should also limit their caffeine intake, as high doses of caffeine can increase the risk of developmental problems and miscarriage.

If you are experiencing any negative effects from caffeine, such as anxiety, panic attacks, insomnia, heart palpitations, headaches, stomachaches, nausea, vomiting, diarrhea, muscle tremors, difficulty breathing, chest pain, seizures, irregular heartbeat, or mental confusion, it is important to stop consuming caffeine or limit your intake and talk to your doctor.
