You started Ozempic or another GLP-1 and now you're second-guessing every part of your routine — including your morning coffee. Fair. When a medication is reshaping your appetite, your digestion, and your relationship with food, you should question what goes in alongside it.
Here's the honest answer: we are not the right source for that decision. Coffee is generally compatible with most eating patterns, but anyone taking a prescription medication should ask their prescriber what fits their situation. Nothing below is medical advice or a statement about how coffee interacts with your medication.
The GI Reality on GLP-1s
The most common side effects of Ozempic, Wegovy, and other GLP-1 agonists are gastrointestinal: nausea, bloating, acid reflux, and slowed gastric emptying. These hit hardest in the first 4-8 weeks as your body adjusts to the medication. Your prescriber is the person to talk to about managing them.
Coffee — especially on an empty stomach — stimulates gastric acid production. If you're already dealing with GLP-1-related nausea and reflux, that is worth raising with your doctor, including whether coffee of any kind belongs in your routine right now.
Why Cold Brew Is the Smarter Play
Cold brew extracts coffee through time (12-24 hours of cold steeping) instead of heat. Cold brewing extracts fewer of the acids that hot brewing pulls from the same beans — research published in Scientific Reports found cold brew has a lower total titratable acidity than hot brew, though pH is comparable. Same caffeine, different acid profile.
That is a property of the brewing method, not a claim about your medication or your symptoms. If you are looking at coffee that is simpler to evaluate, cold brew is at least easy to read on the label.
And if your cold brew is clean — no added sugar, no artificial sweeteners, no "natural flavors" — there is less to account for. Many people on these medications are watching their caloric intake carefully. A cold brew with two ingredients, zero sugar, and 20 calories per can is straightforward to track.
The Sugar Trap on GLP-1s
Here's a detail a lot of GLP-1 users overlook. They cut their food intake dramatically — the medication handles that — but they're still drinking sweetened coffee drinks that can carry 30 grams of sugar or more per serving. Flavored lattes. Sweetened cold brews. Canned coffees with six ingredients including sucralose.
If you are tracking sugar and calories, a sweetened coffee is worth counting the same way food is. Published research on caffeine and blood glucose is about coffee and caffeine generally, not about any one brand, and it is not a reason to change anything about your medication. Talk to your prescriber about that. If you simply want coffee with nothing added, choose an unsweetened cold brew with zero sugar.
Bare Brew is Honduran Arabica cold brew and filtered water. Zero sugar. 20 calories. 320mg of caffeine. Two ingredients and nothing else to look up.
Timing Your Coffee Around Your Shot
If you are wondering whether to space coffee out from your weekly injection, that is a question for your prescriber — there is limited clinical data on the interaction, and we are not going to invent a rule for you.
For daily coffee drinkers on weekly injections, scheduling is easy either way: take your shot the night before, or first thing in the morning before your coffee routine starts.
The Caffeine Limit Still Applies
GLP-1 or not, the FDA guideline is 400mg of caffeine per day for most adults. At 320mg per can, one Bare Brew puts you within that limit with room for a small tea or chocolate later. You're not stacking three weak coffees and wondering where you stand. One can, one number, done.
Bottom Line
Whether coffee belongs in your routine on a GLP-1 is between you and your prescriber. If you do drink it, you can at least pick a coffee you can read the label of: zero sugar, no additives, two ingredients in a gold can.
Always consult your prescribing physician about your specific situation. This isn't medical advice — it's information about coffee.
