However, drinks that are espresso-based such as cappuccinos, lattes, Americanos, and macchiato have about 63 mg to 125 mg of caffeine depending on the size of the drink.
  • Instant Coffee
    This type of coffee is prepared by mixing a teaspoon or two of dried coffee with a cup of boiling water. A cup of instant coffee has roughly 30 to 90 mg of caffeine.
  • Decaf Coffee
    Contrary to popular belief, a cup of decaf coffee is not entirely free of caffeine. In reality, it can contain an average of three mg of caffeine but can sometimes reach up to seven mg. It all depends on the cup size and the method used to turn regular coffee to decaf.

  • Know your dose
