How much coffee is too much? The answer may depend on your individual tolerances, but most experts agree that 400 milligrams of caffeine per day is the safe limit for healthy adults. That’s about four cups of brewed coffee. If you’re pregnant, breastfeeding, or have any pre-existing medical conditions, you should speak to your doctor before increasing your caffeine intake.

Signs you’re drinking too much coffee.

If you’re drinking more than four cups of coffee a day, or if you’re experiencing any of the following side effects, it’s possible that you’re consuming too much caffeine:

Anxiety or jitters


Insomnia or trouble sleeping


Upset stomach or diarrhea

Rapid heartbeat or palpitations

These side effects are usually mild and go away once you reduce your caffeine intake. If you’re experiencing more severe side effects, such as chest pain or difficulty breathing, it’s important to seek medical attention immediately.

How much coffee can you drink in a day? This is a question with no easy answer. Coffee has both benefits and risks that need to be considered.

On the one hand, coffee can improve memory and concentration, physical performance, and mental health. On the other hand, coffee can cause anxiety and sleep problems, stomach discomfort, and an increased heart rate. So how much is too much?

The safe limit for coffee consumption appears to be around 400mg per day – that’s about 4 cups of coffee. However, everyone responds differently to caffeine, so some people may need to drink less than this to avoid side effects. Signs that you’re drinking too much coffee include jitters, headaches, irritability, and difficulty sleeping.

If you’re wondering how much coffee you should drink in a day, the best answer is to listen to your body. Pay attention to how you feel after drinking coffee and adjust your intake accordingly. And remember – moderation is key!
