Can You Have Caffeine When Pregnant?
Written by Jordan Morley · Reviewed against NHS foods-to-avoid guidance · Last updated 28 October 2026
Caffeine is fine during pregnancy in moderation — the NHS says to keep your total caffeine below 200mg a day (about 2 cups of instant coffee).
Why is caffeine a concern in pregnancy?
High caffeine intake in pregnancy has been linked to low birth weight and, at very high levels, miscarriage. The NHS therefore advises limiting caffeine to 200mg per day from all sources combined. As a guide, the NHS gives about 100mg in a cup of instant coffee (filter and coffee-shop coffee can contain more, about 140mg in a mug of filter coffee according to Tommy's), about 75mg in a cup of tea and about 40mg in a can of cola. Caffeine counts towards this daily total.
You can also check the calorie content of caffeine alongside its safety information. Also check medication safety during pregnancy if you're managing any conditions.
The exception
Remember caffeine adds up across coffee, tea, green tea, cola, energy drinks and chocolate — count everything towards the 200mg limit.
