How much caffeine is in Diet Coke, Coca‑Cola, Coke Zero and Coca‑Cola Life?

People often think our drinks contain high amounts of caffeine, but in fact there are only 32mg of caffeine in a 330ml can of Coca‑Cola or Coke Zero, 42mg in a can of Diet Coke and 26mg in a can of Coca‑Cola Life. To help put this in context, a mug of tea contains about 75mg of caffeine, and a mug of coffee provides about 100mg of caffeine.

So the levels of caffeine in Coca‑Cola are actually relatively low in comparison to other drinks. However, if you want to avoid caffeine or reduce your intake, try Caffeine-Free Diet Coke or one of our other caffeine-free sparkling brands, such as Fanta, Sprite or Lilt.
