Most health authorities agree that for most healthy adults, consuming up to 400 milligrams (mg) of caffeine per day is considered safe. This amount roughly corresponds to about four 8-ounce cups of brewed coffee, though the exact caffeine content can vary widely depending on the coffee type and preparation method

. Key points on coffee consumption limits:

  • Safe upper limit: About 400 mg of caffeine daily, equivalent to roughly 3 to 5 cups of coffee for most adults
  • Variability: Caffeine content per cup varies from about 50 mg to over 300 mg depending on size and brew strength, so cup count is an estimate
  • Health risks: Drinking six or more cups per day may increase the risk of cardiovascular issues by up to 22%, according to some studies
  • Individual tolerance: Sensitivity to caffeine varies based on genetics, health conditions, medications, pregnancy status, and other factors, so some people may need to limit intake further
  • Children and pregnant women: Lower limits apply; pregnant women are advised to limit caffeine to less than 200 mg daily, and children should consume far less caffeine

In summary, drinking around 3 to 5 cups of coffee per day is generally safe for most healthy adults, but exceeding about 6 cups daily may increase health risks, particularly for the heart. Individual tolerance and health status should guide personal consumption levels
