How much caffeine should you take?

According to the studies at the U.S Food & Drug Administration (FDA), caffeine can be part of a healthy diet for most people, but too much caffeine may pose dangerous effects to our health. The FDA recommends a maximum intake of 400 milligrams a day (that’s about four or five cups of coffee).

However, the amount of caffeine in beverages vary depending on the type of beans used to how the product was processed. As a general rule of thumb, the FDA compiled a rough list of reference on caffeine content in selected beverages.

  • 12 ounce can of caffeinated soft drink: 30-40mg
  • 8 ounce green or black tea: 30-50mg
  • 8 ounce coffee: 80-100mg
  • Caffeine in energy drinks per 8 ounces: Ranges from 40-250mg

FDA listed common symptoms of overconsuming coffee as :

  • insomnia
  • jitters
  • anxiousness
  • fast heart rate
  • upset stomach
  • nausea
  • headache
  • a feeling of unhappiness (dysphoria)
