Add what you actually had
Tap a drink below, or type the figure from your own label or menu. Nothing is uploaded. Today's list is kept on this device so you can add to it through the day.
ACOG advises keeping daily caffeine intake below 200 mg during pregnancy.
Add a common drink
NHS estimates. Use the figure on the label or menu instead when you have one, since coffee-shop drinks in particular vary.
Add a named drink
From each brand's own published figures. Where Starbucks gives a range, the top of it is used.
Daily total
0 mg logged
Add the caffeine amount from each label, menu, or manufacturer listing.

The reference point depends on your country
The U.S., UK, Australia, Ireland, and Canada do not all use the same wording or number. Select where you live in the calculator and open the linked authority if you need the full guidance. Advice from your own doctor, midwife, or dietitian takes priority when it is more specific.
| Country | Daily reference | Authority |
|---|---|---|
| United States | 200 mg | American College of Obstetricians and Gynecologists |
| United Kingdom | 200 mg | NHS |
| Canada | 300 mg | Health Canada |
| Australia | 200 mg | Pregnancy, Birth and Baby |
| Ireland | 200 mg | Health Service Executive |
Caffeine can hide outside coffee
Tea, cola, energy drinks, chocolate, guarana, yerba mate, pre-workout products, supplements, and some cold, flu, or pain medicines may add to the day. Read the whole label. Ask a doctor or pharmacist before using a medicine or supplement during pregnancy.
Check the wording on a product labelHow much caffeine is actually in things
If the label does not give a number, these are the NHS estimates for common foods and drinks. They are a starting point for the calculator above, not a measurement of the specific cup in your hand.
| Food or drink | Estimated caffeine | What changes it |
|---|---|---|
| Instant coffee | 100 mg per cup | NHS notes filter coffee and coffee bought from coffee shops can contain more. |
| Tea, black or green | 75 mg per cup | Brewing time changes the result, so a strong long-brewed cup sits higher. |
| Energy drink | 80 mg per 250 ml can | Larger cans and pre-workout products can be far higher. Check the label. |
| Cola | 40 mg per can | Diet and regular versions can differ, and some colas carry more. |
| Plain dark chocolate | Less than 25 mg per 50 g bar | Counts toward the day, though it is rarely what pushes a total over. |
| Plain milk chocolate | Less than 10 mg per 50 g bar | The smallest common source on this list. |
Estimates from NHS pregnancy guidance on foods to avoid.
Against a 200 mg reference, two cups of instant coffee will use most of the day on their own. That is the practical reason people are surprised: the total goes not from one big drink but from a coffee, a tea in the afternoon, and a cola with dinner.
Caffeine in Starbucks, Costa, Celsius and other named drinks
The NHS figure of 100 mg is for a cup of instant coffee, and the NHS says coffee from coffee shops can contain more. Starbucks lists a grande Pike Place Roast at 315 to 390 mg, which is over the 200 mg daily limit on its own.
| Drink | Size | Caffeine | Share of 200 mg | Source |
|---|---|---|---|---|
| Starbucks Pike Place Roast | Grande, 16 fl oz | 315–390 mg | 195% | Starbucks |
| Starbucks Cold Brew | Grande, 16 fl oz | 205 mg | 102% | Starbucks |
| Starbucks Caffè Latte | Grande, 16 fl oz | 150 mg | 75% | Starbucks |
| Celsius | 1 can | 200 mg | 100% | Celsius |
| Monster Energy | 16 fl oz can | 160 mg | 80% | Monster Energy |
| Red Bull | 250 ml / 8.4 fl oz can | 80 mg | 40% | Red Bull |
| Diet Coke | 12 fl oz can | 46 mg | 23% | Coca-Cola |
| Coca-Cola | 12 fl oz can | 34 mg | 17% | Coca-Cola |
| Costa cappuccino | Medium | 325 mg in a Which? test | 163% | Which?, via RTÉ |
| Costa flat white | Regular | 241 mg in a Which? test | 121% | Which?, via RTÉ |
| Greggs cappuccino | Medium | 235 mg in a Which? test | 118% | Which?, via RTÉ |
| Caffè Nero cappuccino | Medium | 221 mg in a Which? test | 111% | Which?, via RTÉ |
| Starbucks UK cappuccino | Medium | 89 mg in a Which? test | 45% | Which?, via RTÉ |
U.S. figures read from each brand's own page on 28 September 2026. Where a range is published, the share uses the top of it.
Costa, Caffè Nero and Greggs do not publish caffeine. When Which? tested medium cappuccinos in August 2026, Costa's had 325 mg and Starbucks's had 89 mg, more than a threefold gap for the same order. Which? pointed to pregnancy as a reason to pay attention to the difference. These are single lab samples, so treat them as a guide to which chains run high rather than an exact figure for your cup.
Herbal tea is a separate question
Herbal teas are usually caffeine free, so they do not add to the total above. That does not make them unlimited. NHS guidance is to drink no more than 4 cups of herbal tea a day during pregnancy, and to avoid teas containing liquorice root.
The reason given is honest uncertainty rather than a known harm: there is not much research on the effects of drinking herbal teas in pregnancy, so the advice is to limit rather than to rely on them as a free swap for coffee.
If you went over or feel unwell
A daily total is not an exposure assessment or diagnosis. It cannot tell you whether a pregnancy was affected. Contact your doctor, midwife, pharmacist, poison service, or urgent service as appropriate if you are worried about the amount, a concentrated caffeine product, a medicine, or symptoms.
Pregnancy caffeine questions
How much caffeine can I have during pregnancy?
Current guidance differs by country. ACOG advises less than 200 mg a day in the United States. The NHS, Australia's Pregnancy, Birth and Baby service, and Ireland's HSE use a 200 mg daily limit. Health Canada recommends a maximum of 300 mg a day.
What should I count toward my caffeine total?
Count every source you consume that day. This can include coffee, black or green tea, cola, energy drinks, chocolate, guarana, yerba mate, supplements, and some medicines. Check medicine use with a doctor or pharmacist during pregnancy.
Is one Starbucks coffee OK while pregnant?
It depends on the drink. Starbucks lists a grande Pike Place Roast at 315 to 390 mg, which is over the 200 mg daily limit used in the U.S. and U.K. on its own. A grande Caffè Latte is 150 mg and a grande Cold Brew is 205 mg. A tall or short drip coffee, or a decaf, leaves more room. Check the size before the drink.
Can I drink Celsius while pregnant?
Celsius says each can holds 200 mg of caffeine. That is the whole daily limit ACOG and the NHS use, in one can, before any coffee, tea or chocolate. It also contains other added ingredients, so ask your midwife or doctor before relying on energy drinks during pregnancy.
Can this calculator know the caffeine in my coffee?
Only roughly. It carries published figures for common Starbucks, Celsius, Monster, Red Bull and Coca-Cola drinks, and Which? lab results for Costa, Caffè Nero and Greggs. Caffeine still varies with the beans, size and brew, so use the figure on your own label or menu when you have one.
What if I logged more than the reference point?
The total cannot estimate risk or tell you whether a pregnancy was affected. Follow your clinician's advice and contact them if you are worried about your intake, symptoms, a medicine, or a concentrated caffeine product.
Keep the drink with the rest of your day
Ask Nouri about the exact drink or log it with your meals. The app keeps the product, serving, pregnancy week, and daily context together instead of reducing the question to coffee alone.
