Are Poppi Drinks Safe For Pregnancy? | What Experts Say

No, there isn’t enough research to call Poppi drinks safe during pregnancy — experts recommend checking with your obstetrician before drinking them.

Poppi and other prebiotic sodas are marketed as a healthier alternative to regular soda, with low sugar, no artificial sweeteners, and added gut-health ingredients. But when you’re pregnant, “healthier” doesn’t automatically mean “safe.”

Right now, no published studies have looked at Poppi specifically in pregnancy. An ob-gyn and maternal-fetal medicine specialist told BabyCenter the honest truth is that we don’t know if these drinks are safe. The brand itself also directs pregnant customers to consult a physician before consuming their product.

What’s Inside a Poppi Can

Poppi is a carbonated drink that combines prebiotic fiber (inulin), apple cider vinegar, fruit juice, and five grams of sugar or less per 12-ounce can. It contains about 25 to 50 calories and only a few flavors include caffeine.

Inulin is a type of soluble fiber that feeds beneficial gut bacteria. The amount in a single Poppi can is relatively small — maybe two to five grams — which is far less than the daily fiber intake most adults need.

The apple cider vinegar content is also low, typically about one teaspoon per can. For most pregnant people, that amount is not likely to cause issues, but everyone’s tolerance is different.

Why the Safety Question Is Tricky

Pregnancy puts every ingredient under a microscope. The gut microbiome changes during pregnancy, and a new drink that alters gut bacteria could theoretically have effects no one has tested. Here’s what makes the answer complicated:

• No Poppi-specific pregnancy research: The only relevant clinical data comes from general probiotic and prebiotic supplementation studies, which are positive but don’t test this specific product or dose.
• Inulin can cause bloating: Prebiotic fiber ferments in the gut. Many pregnant women already deal with gas and bloating, and inulin can make that worse — especially if you’re not used to high-fiber foods.
• Moderation is key: Even safe ingredients can be problematic in large amounts. One can occasionally is different from drinking several per day.
• The brand itself hedges: Poppi’s website says “because everyone is different, pregnant individuals should reach out to their physician for advice.”

Given these factors, it’s not that Poppi is known to be dangerous — it’s that nobody knows for sure. That uncertainty is enough for many experts to recommend caution.

What Research Says About Prebiotics in Pregnancy

The strongest evidence comes from a 2021 systematic review of probiotic and prebiotic supplementation during and after pregnancy. That review, published in PMC, analyzed data from multiple trials and found that supplementation with these products was not associated with any serious health outcomes in mothers or infants. The full details are available in the probiotic prebiotic pregnancy safety review.

The PMC review gives some reassurance that prebiotic supplements generally aren’t harmful during pregnancy. But it’s important to remember that Poppi is a specific combination of ingredients — not a pure prebiotic supplement — and the review didn’t test this exact product.

How to Decide If Poppi Is Right for You

If you are curious about trying Poppi during pregnancy, here’s a step-by-step approach that many healthcare providers would find reasonable:

1. Ask your obstetrician first. Your OB knows your full health history, including any digestive issues, gestational diabetes risk, or other factors that could make Poppi more or less suitable for you.
2. Start with half a can. If you get the green light, try a small amount to see how your body reacts. Some women find that inulin causes gas or bloating, especially in the second and third trimesters.
3. Read the label for caffeine. Most Poppi flavors are caffeine-free, but a couple contain a small amount (from green tea or coffee fruit). If you are avoiding caffeine entirely, choose a caffeine-free flavor.
4. Consider simpler alternatives. Sparkling water with a splash of lemon or lime, or plain water with fresh fruit, provide similar refreshment without any unknown ingredients.

Ultimately, the decision comes down to your personal comfort level and your doctor’s advice. There is no evidence that Poppi is harmful, but the lack of pregnancy-specific testing means you are the one taking the unknown risk.

Poppi vs. Traditional Soda: Nutrition Comparison

Compared to a standard 12-ounce soda, Poppi is undeniably lower in sugar and calories. The Mayo Clinic notes that prebiotic sodas like Poppi contain five grams of sugar or less and 50 or fewer calories per can, while a typical cola packs about 39 grams of sugar and 140 calories. The full nutrition profile is outlined in the prebiotic soda nutrition facts article from Mayo Clinic Press.

Poppi also avoids artificial colors and preservatives in most flavors. That makes it a cleaner choice than many sodas, but “cleaner” does not automatically equal “pregnancy-safe.” The real question is whether the active ingredients — inulin and apple cider vinegar — pose any hidden risk, and that question remains unanswered for this population.

The Bottom Line

Poppi drinks are low in sugar and free of artificial sweeteners, which makes them a better option than regular soda in many ways. But the lack of pregnancy-specific research means that the safest course is to treat Poppi like any other new food or drink during pregnancy: get your OB’s approval first, start with a small amount, and pay attention to how you feel.

Your obstetrician can weigh your individual health status — including any history of gestational diabetes, digestive sensitivities, or other risk factors — and help you decide whether Poppi fits safely into your prenatal diet.
