If you’re pregnant and craving coffee, you’re not alone, mama. For many of us, that morning cup feels less like a treat and more like survival fuel — especially when pregnancy fatigue hits. But then comes the question: Is coffee safe in pregnancy? And what about with gestational diabetes (GD)?
Let’s break it down together.
The good news? According to most major medical guidelines — including ACOG (American College of Obstetricians and Gynecologists) — up to 200mg of caffeine per day is considered safe in pregnancy. That’s about one 12-ounce cup of brewed coffee.
A few important things to know:
Caffeine crosses the placenta. Your baby processes caffeine much more slowly than you do, which is why moderation is important.
Coffee isn’t the only source. Tea, chocolate, sodas, energy drinks, and even some medications contain caffeine — it all adds up.
Everyone’s tolerance is different. Some pregnant women feel jittery or nauseous with even a small amount, while others feel fine.
If you love coffee but want to cut back:
Try half-caf or decaf.
Experiment with cold brew — it’s often smoother and lower in acidity.
Drink slowly, and avoid coffee on an empty stomach.
Now let’s talk about the gestational diabetes side of things — because coffee isn’t just about caffeine, it’s also about how it impacts blood sugar.
Here’s what we know:
Coffee can temporarily increase insulin resistance. This means your body might not handle carbs as well right after drinking coffee. Some GD mamas notice their readings run higher on mornings they have coffee.
Responses vary. For some, coffee doesn’t affect blood sugar at all. For others, it causes unexpected spikes — especially when paired with milk or sugar.
What’s in your cup matters. Sometimes it’s not the coffee, but the add-ons that drive up blood sugar.
Better choices:
Unsweetened almond milk
Unsweetened coconut milk
Heavy cream or half-and-half (higher fat, very low carb)
Trickier options:
Oat milk (often high carb, even unsweetened)
Dairy milk (especially in the morning, when it can spike more easily)
Flavored creamers (usually packed with hidden sugars)
Always check nutrition labels — some “barista” plant milks have 10–15g carbs per cup! You can read more about best milk options for gestational diabetes in our Milk & GD blog post and about choosing the best coffee creamer for gestational diabetes in our Coffee Creamer & GD blog post.
Safer swaps:
Stevia, monk fruit, or allulose (natural, blood-sugar-friendly)
Sugar-free syrups (just watch for sugar alcohols, which can upset the stomach)
Best to avoid:
Regular syrups (vanilla, caramel, pumpkin spice, etc.) — these can pack 15–30g sugar in just a few pumps
Agave or honey (still sugar and often spike-inducing)
Cinnamon
Unsweetened cocoa powder
Nutmeg or pumpkin spice (without sugar)
Vanilla extract (just a drop)

In the short term, caffeine can make your body a bit more resistant to insulin. That means after a cup of coffee (or another caffeinated drink), blood sugar may spike a little higher than usual. This effect shows up more strongly in people with diabetes, though not everyone reacts the same way.
Interestingly, long-term studies show that regular coffee drinkers often have a lower risk of developing type 2 diabetes. That might be because the body builds up a tolerance to caffeine, and also because coffee contains other beneficial compounds — like chlorogenic acid — which can improve insulin sensitivity and help with glucose control.
If you’re sensitive to caffeine or just want to be cautious, decaf is a great option. It still contains antioxidants and chlorogenic acid, but without the stronger impact caffeine can have on blood sugar. For people with gestational diabetes or type 2 diabetes, decaf can sometimes be the safer bet while still letting you enjoy the taste and ritual of coffee.
Coffee isn’t just about caffeine. Its natural compounds — especially chlorogenic acid — can help slow down glucose absorption in the gut, improve how your body responds to insulin, and even reduce inflammation. That’s part of why coffee often shows up in research as being linked to lower diabetes risk over time.
Notice your own patterns. Check your blood sugar and see how caffeine affects you personally — everyone’s different.
Drink with food. Coffee on an empty stomach can cause more noticeable spikes. Pairing it with a balanced meal helps.
Try decaf or half-caf. Especially if you notice caffeine pushes your numbers up.
Watch the add-ins. Sugary syrups, flavored creamers, and sweeteners can raise blood sugar far more than the coffee itself.
Stay hydrated. Balance your coffee with water throughout the day.
Not every mama feels good drinking coffee with GD, and that’s okay. A few alternatives you can try:
Decaf coffee (small caffeine, but often tolerated better).
Chicory coffee — naturally caffeine-free, similar roasted flavor. Stick to moderate amounts and avoid chicory supplements during pregnancy.
Herbal teas — just make sure they’re pregnancy-safe (peppermint and rooibos are usually safe, but always double-check).
Coffee doesn’t have to be “off-limits” during pregnancy or with gestational diabetes. It’s all about moderation, testing, and finding what works for your body.
If you love your morning cup, chances are you can still enjoy it — maybe with a few tweaks. And if coffee just doesn’t sit well for you right now? That’s okay too. This season is temporary, and your comfort (and energy) matter just as much as the numbers.
You’re doing an amazing job, mama — coffee or no coffee. 💛
1. How much coffee is safe during pregnancy?
Most guidelines suggest up to 200mg of caffeine per day — roughly one 12-oz cup of brewed coffee. Staying within this caffeine intake limit is considered safe for most healthy adults, including pregnant mamas.
2. Can coffee spike blood sugar with gestational diabetes?
Sometimes, yes — caffeine affects blood sugar by temporarily increasing insulin resistance and causing blood sugar spikes, especially in people with gestational diabetes mellitus or other types of diabetes. However, blood sugar levels can also be influenced by add-ons like sugary syrups, flavored creamers, or too much milk. The best approach is testing your own blood glucose response to see how your body reacts to coffee consumption.
3. Is decaffeinated coffee safe in pregnancy?
Yes! Decaffeinated coffee has a much lower caffeine content and is generally safe during pregnancy. It also tends to have less impact on blood sugar control, making it a good alternative for those sensitive to caffeine.
4. What's the best milk for coffee if I have gestational diabetes?
Low-carb options like unsweetened almond milk, unsweetened coconut milk, or heavy cream are usually easier on blood glucose levels. Traditional dairy milk, oat milk, or flavored creamers can sometimes cause higher postprandial responses and blood sugar spikes, especially in the morning. Read more about the best and worst milks for gestational diabetes in our Milk & GD blog post.
5. Can I have flavored lattes or mochas with gestational diabetes?
Generally yes — but choose sugar-free syrups or natural flavorings like cinnamon, unsweetened cocoa powder, or vanilla extract. Regular syrups and pre-made drinks often contain hidden sugars that can negatively affect glucose metabolism. Opt for low-carb milk alternatives to maintain better blood sugar control.
6. Can I have iced coffee or cold brew?
Generally yes — just watch for sweeteners, flavored syrups, and milk choices. Cold brew often has a smoother taste and lower acidity, which some find easier to tolerate without causing blood sugar fluctuations.
7. What about creamers or non-dairy creamers?
Always check labels for caffeine content and added sugars. Many “fat-free” or flavored creamers contain hidden sugar that can raise blood glucose levels. Stick to unsweetened versions or add a splash of heavy cream to your coffee.
8. Is timing important for coffee during gestational diabetes?
Yes — some mamas find blood sugar spikes are more noticeable if coffee is consumed before breakfast. Pairing your morning coffee with protein or healthy fats can help buffer postprandial blood sugar increases and improve glucose tolerance.
9. Can coffee affect insulin or medication?
Caffeine in caffeinated beverages can temporarily affect insulin sensitivity and insulin response. If you're on insulin or other diabetes care medications, monitor your blood sugar closely and adjust as needed under your healthcare provider's guidance.
10. Are there other tips for enjoying coffee safely?
Keep portion sizes moderate to avoid too much caffeine intake.
Avoid sugar bombs like sweetened syrups and whipped cream.
Drink water alongside coffee to stay hydrated and support blood glucose control.
Test your blood sugar response after trying new drinks to understand your body's reaction.
Remember — coffee isn't the enemy; it's all about balance, mindful caffeine consumption, and healthy add-ons.
