Caffeine is found in tea and coffee, cola, other soft drinks and chocolate. In pregnancy you should have no more than 200mg a day.

  • A can of cola has around 40mg of caffeine
  • A mug of tea has around 75mg
  • A bar of plain chocolate has around 50mg
  • A cup of instant coffee has around 100mg
  • A mug of filter coffee has around 140mg
  • Energy drinks: a 250ml can has around 80mg.

If you drink sports drinks, check the amount of caffeine in these too. Some now have caffeine added.

It can add up quickly! You will be reaching your limit with, for example:

  • one bar of plain chocolate and one mug of filter coffee
  • two mugs of tea and one can of cola.

Cutting down on caffeine

Decaffeinated tea and coffee, fruit juice or water are all good choices if you are used to drinking a lot of caffeinated drinks. Limit the amount of energy drinks you have, as they can be high in caffeine. Don’t worry if you have in the past gone over the 200mg limit. The risks are quite small.
