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.

High levels of caffeine during pregnancy can result in low birth weight babies, which can increase the risk of health problems in later life. Too much caffeine has also been linked to miscarriage.

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.

      12 weeks and past three days I wake up with this hunger feeling combined with sickness. It’s horrible to bear. I try eating biscuits still I need to vomit a bit after. How do I control this.

      If I add them here I am just above at 240mg... but I think if i drink less quantity... it should be lower

      What about Chicory Essence coffee like Camp Coffee? How much caffeine is in that? The company told me it has "0.15% caffeine in the entire bottle" but that doesn't mean much when I don't know the density to calculate how many mg that is in a teaspoon full!
      Thanks in advance
