How Much Coffee Can I Drink While Pregnant?
Updated June 2026 · based on NHS and official food-safety guidance
The NHS in the UK and ACOG and the FDA in the US set the same ceiling: no more than 200mg of caffeine per day. That is about two mugs of instant coffee (around 100mg each) or one and a half mugs of filter or brewed coffee (around 140mg each). Regularly going over 200mg is linked to a higher risk of low birth weight and miscarriage, so the safest move is to count caffeine from every source, not just coffee.
Coffee is one of the first things people wonder about once they see a positive test, and the good news is you do not have to give it up. The official advice in both the UK and the US is the same: you can keep enjoying coffee as long as your total caffeine for the day stays under 200mg. The tricky part is that caffeine hides in tea, cola, energy drinks, chocolate and even some cold and flu remedies, so it adds up faster than you might expect. Below you will find how much caffeine is in common drinks, what counts toward your daily 200mg, and how the UK and US guidance lines up, so you can pour your cup without second-guessing every sip. For a specific product, the Muka app gives you a verdict in 3 seconds by barcode scan or photo.
Common caffeine sources and your 200mg daily limit
| Drink or food | Verdict | Caffeine and why |
|---|---|---|
| Instant coffee (1 mug) | Safe | About 100mg of caffeine, so one mug sits comfortably under the 200mg daily limit. Two mugs takes you right to the ceiling, leaving no room for tea or chocolate that day. |
| Filter or brewed coffee (1 mug) | In moderation | Around 140mg in a single mug, more than half your daily allowance. One is fine, but a second would push you over 200mg, so treat it as a one-a-day treat. |
| Espresso or shop latte/cappuccino | In moderation | One shot is roughly 63 to 75mg, but large takeaway drinks can contain two or three shots. Ask for a single shot and check the cup size, as a large can hide 150mg or more. |
| Decaf coffee | Safe | Only about 2 to 15mg per cup, so it barely registers against your 200mg limit. A solid swap if you want the ritual and taste without the caffeine load. |
| Energy drinks | Avoid | A 250ml can holds around 80mg of caffeine plus added sugar and other stimulants. They are best avoided in pregnancy and are a common reason people tip over the 200mg limit, so skip them rather than counting them in. |
| Tea, cola and chocolate | In moderation | A mug of tea is about 75mg, a can of cola 40mg, a 50g dark chocolate bar under 25mg. They are fine in small amounts, but they all eat into the same 200mg total as coffee. |

Is one cup of coffee a day safe during pregnancy?
Yes. One mug of instant coffee is about 100mg of caffeine, well within the 200mg daily limit set by the NHS, ACOG and the FDA. Just remember other drinks and chocolate add to your total, so leave room if you have tea or cola later that day.
How many cups of coffee equal 200mg of caffeine?
Roughly two mugs of instant coffee at about 100mg each, or one and a half mugs of filter or brewed coffee at around 140mg each. Coffee-shop drinks vary widely because large sizes can contain two or three espresso shots, so check the size and shot count.
What happens if I drink too much coffee while pregnant?
Regularly going over 200mg of caffeine a day is linked to a higher risk of low birth weight and miscarriage, according to the NHS. Caffeine also crosses the placenta, and your baby cannot process it as quickly as you can, which is why the limit exists.
I drank a lot of coffee before I knew I was pregnant. Should I worry?
Try not to panic. A short stretch of higher intake before you knew is very unlikely to cause harm, and the guidance is about regular daily amounts over time. Simply cut back to under 200mg a day from now on and mention it to your midwife or doctor if you are anxious.
Can I drink decaf coffee while pregnant?
Yes. Decaf contains only about 2 to 15mg of caffeine per cup, and ACOG considers it safe in moderation during pregnancy. It is an easy way to keep the taste and routine of coffee while staying well under your 200mg daily caffeine limit.
