Here's how much coffee you can drink for your health
Recent research suggests that moderate coffee consumption, capped at 400mg of caffeine daily, may offer cardiovascular and liver health benefits. Experts warn that high-caffeine energy drinks should be avoided due to potential heart risks.
Why it matters
Understanding the health impacts of common dietary habits like coffee consumption helps individuals make informed lifestyle choices.
Reduced risks of various diseases, better liver health, and perhaps even a longer life: The potential health benefits of coffee have been highlighted by a growing body of research in recent years.
According to the American Heart Association (AHA), up to five cups of coffee a day is safe for most people, citing new research recommending a cap of 400mg of caffeine.
Exceeding the limit increases the risk of high blood pressure and heart failure.
Sticking to that upper limit, which equates to around two double-shot and one single-shot espressos, is not only a safe choice, but could also boost heart health.
Moderate coffee intake appears to be not only “generally safe for most adults”, but also “linked to a lower risk of several cardiovascular conditions, including heart failure, heart disease and stroke in some individuals”, the AHA said in July (2026).
