Ginger ale is unlikely to help GERD or acid reflux and may actually make symptoms worse. The drink combines two things that work against you: carbonation, which can weaken the muscular valve that keeps stomach acid out of your esophagus, and sugar, which adds calories without therapeutic benefit. Meanwhile, most commercial ginger ales contain so little actual ginger that the digestive benefits associated with the root are barely relevant. The story is more nuanced than a flat “no,” though, because ginger itself has some genuinely interesting effects on the gut.
What Carbonation Does to the Valve That Guards Your Esophagus
The lower esophageal sphincter (LES) is a ring of muscle at the bottom of your esophagus that opens to let food into the stomach and then closes to keep acid from splashing back up. When that valve weakens or relaxes at the wrong time, you get reflux. Carbonated beverages are a problem because the dissolved carbon dioxide creates gas in the stomach, stretching it. That stretch triggers relaxation of the LES.
Research measuring LES pressure after carbonated drinks found that all carbonated beverages produced a sustained drop of 30 to 50 percent in sphincter strength lasting about 20 minutes. In roughly 62 percent of cases, that drop was large enough to push the sphincter into a range that would normally be considered incompetent, meaning it could not reliably keep acid in the stomach. Tap water, by contrast, caused no change at all.1PubMed Central. Response of the lower esophageal sphincter to gastric distention by carbonated beverages
A systematic review looking at the broader evidence on carbonated beverages and GERD found a more mixed picture. Carbonated drinks do cause a brief dip in esophageal pH and a temporary reduction in sphincter pressure. But the review concluded there was no consistent evidence that carbonated beverages directly cause esophageal damage or reliably trigger GERD symptoms in everyone.2PubMed. Systematic review: the effects of carbonated beverages on gastro-oesophageal reflux disease That does not mean carbonation is harmless for people who already have reflux problems. It means the relationship is not as straightforward as “carbonation equals heartburn,” but if you are prone to reflux, the temporary sphincter weakening is a real and measurable risk.
How Much Ginger Is Actually in Ginger Ale
Most people reach for ginger ale assuming it delivers the benefits of ginger root. The reality is that many commercial brands contain little more than carbonated water, high-fructose corn syrup, and “natural flavors” that may or may not include meaningful amounts of ginger. One proteomics study analyzed a ginger beverage that claimed to be produced with ginger root extract. Researchers found grape and apple proteins easily but could not detect even a trace of ginger root proteins.3Journal of Proteomics. Ginger Rogers? No, Ginger Ale and its invisible proteome The tasters could detect ginger’s characteristic spicy bite, so some ginger extract was present, but it was clearly a minor ingredient compared to the fruit juices.
A broader analysis measuring the active compounds in ginger products, specifically gingerols and shogaols, found that beverages averaged about 1.77 milligrams of these compounds per gram. That is far less than ginger supplements, which averaged around 10 milligrams per gram, and also well below dried ginger spices at about 9 milligrams per gram.4European Journal of Integrative Medicine. Determination of the concentration of major active anti-emetic constituents within commercial ginger food products and dietary supplements A few ginger beverages did contain compound levels comparable to dietary supplements when measured per serving, but those were outliers. The typical can of ginger ale from a grocery store shelf is not one of those outliers.
This matters because the digestive effects people associate with ginger come from its active compounds. If the drink barely contains them, it is essentially a sugary soda with ginger flavoring. You would need to check ingredients carefully or choose craft-style ginger brews that list real ginger root prominently to get anything close to a therapeutic amount.
What Ginger Root Actually Does for Digestion
Ginger itself, not ginger ale but the actual root and its concentrated extracts, does have measurable effects on the gastrointestinal system. The most consistent finding is that ginger speeds up gastric emptying, which is how quickly food moves from the stomach into the small intestine. In one study, the half-emptying time after ginger was about 12 minutes compared to 16 minutes with placebo.5PubMed Central. Effect of ginger on gastric motility and symptoms of functional dyspepsia Another study found an even more dramatic difference, with ginger cutting gastric half-emptying time roughly in half compared to placebo while also increasing the frequency of stomach contractions.6PubMed. Effects of ginger on gastric emptying and motility in healthy humans
Faster gastric emptying is relevant to reflux because a full, distended stomach increases the likelihood that acid will push past the lower esophageal sphincter. If food clears the stomach more quickly, there is less time and less pressure for reflux to happen. That said, the studies demonstrating this used ginger preparations far more concentrated than what you would find in a glass of ginger ale.
There is also early laboratory evidence that 6-gingerol, one of ginger’s key active compounds, may directly increase the tone of the lower esophageal sphincter in isolated tissue.7Food Chemistry. Effects of standardized [6]-gingerol extracts and [6]-gingerol on isolated ileum and lower esophageal sphincter contractions in mice A stronger LES would be exactly what someone with reflux wants. But this was tested in mouse tissue, not in living humans drinking ginger ale. It is a promising lead rather than a proven benefit.
For nausea relief, which is why many people grab ginger ale in the first place, a systematic review of clinical trials found that divided daily doses of around 1,500 milligrams of ginger were effective.8PubMed Central. Ginger in gastrointestinal disorders: A systematic review of clinical trials That is a substantial dose of actual ginger, well beyond what a typical ginger ale provides. The nausea-calming reputation of ginger ale likely comes from the root’s real anti-nausea properties, but the drink itself is a very dilute delivery vehicle for them.
When Ginger Can Actually Trigger Heartburn
Here is where things get counterintuitive: ginger itself, especially at higher doses, can cause the very symptom you are trying to avoid. In a clinical trial of ginger supplementation for digestive issues, the most commonly reported side effects were mild bloating at about 15 percent, heartburn at about 13 percent, and diarrhea at around 11 percent. All of these were described as transient and self-limiting, and nobody dropped out of the study because of them.9Current Therapeutic Research. Evaluation of Adverse Effects and Tolerability of Dietary Ginger Supplementation in Patients With Functional Dyspepsia A separate trial noted that high doses of ginger may cause gastrointestinal side effects including heartburn and stomach discomfort.10Advances in Integrative Medicine. Effects of ginger supplementation on quality of life in patients with functional dyspepsia: An open-label, clinical trial
So even concentrated ginger, used in amounts that actually contain therapeutic levels of active compounds, can provoke heartburn in a meaningful fraction of people. If you are someone whose reflux is already acting up, adding ginger on top of carbonation and sugar is a gamble. You might get the gastric-emptying benefit, or you might just add another irritant to an already inflamed situation.
What Clinical Guidelines Say About Carbonated Drinks and GERD
The American College of Gastroenterology’s clinical guidelines for GERD management include carbonated beverages among the foods and drinks that people are commonly advised to avoid. The guidelines note that coffee, tea, and soda at six servings per day were associated with increased reflux symptoms compared to none, and that substituting water for two servings of these beverages was associated with a decrease in GERD symptoms.11PubMed Central. ACG Clinical Guideline: Guidelines for the Diagnosis and Management of Gastroesophageal Reflux Disease However, the same guidelines acknowledge that supporting data for many of these dietary recommendations are limited, often involving only small studies, and rarely used as the only intervention.
The honest takeaway from the guidelines is not that carbonated beverages are guaranteed to worsen reflux in every person, but rather that they are on the list of reasonable things to try cutting back on. Ginger ale falls squarely in the carbonated-and-sugary category that the guidelines flag.
The Sugar Problem
Beyond carbonation and the ginger question, there is the simple issue of sugar. A standard 12-ounce can of ginger ale typically contains around 32 to 36 grams of sugar, comparable to most other sodas. Excess sugar intake contributes to weight gain, and excess body weight is one of the strongest and most consistent risk factors for GERD. The ACG guidelines list weight loss for overweight patients as one of their dietary and lifestyle recommendations for managing reflux.11PubMed Central. ACG Clinical Guideline: Guidelines for the Diagnosis and Management of Gastroesophageal Reflux Disease
Regularly drinking sugary sodas as a reflux remedy is a pattern that can work against you over time even if any single can does not immediately trigger symptoms. Diet ginger ale sidesteps the sugar issue but still delivers the carbonation, so it is not a clean solution either.
Better Ways to Get Ginger’s Digestive Benefits
If you are interested in ginger for its stomach-settling properties, there are formats that deliver meaningful amounts of the active compounds without the downsides of ginger ale. Ginger tea, made by steeping fresh sliced ginger root in hot water, provides gingerols and shogaols in a non-carbonated, unsweetened form. Ginger supplements and capsules contain far higher concentrations of the active compounds than beverages do.4European Journal of Integrative Medicine. Determination of the concentration of major active anti-emetic constituents within commercial ginger food products and dietary supplements Dried ginger spice is also surprisingly potent compared to commercial ginger drinks.
If you want a carbonated ginger drink specifically, artisanal or craft ginger beers made with real ginger root tend to contain more of the active compounds than mainstream ginger ales. But the carbonation concern still applies. For reflux specifically, the safest route is a non-carbonated ginger preparation at a moderate dose, and keeping an eye on whether it triggers heartburn for you personally.
Individual Triggers Matter More Than General Rules
One of the frustrating aspects of GERD dietary advice is that it is highly individual. A food that reliably triggers one person’s reflux may be completely fine for someone else. Research has found that most patients with GERD can identify at least one food that triggers their symptoms, and that an approach based on avoiding personally identified triggers can be effective in the short term.12PubMed. Elimination of Dietary Triggers Is Successful in Treating Symptoms of Gastroesophageal Reflux Disease This means that while ginger ale checks several boxes for “likely to aggravate reflux,” there are probably people out there who drink it without any trouble.
Structured dietary interventions have shown promise for GERD management. One review found that systematic trigger food elimination protocols improved GERD scores by about 23 percent and enabled nearly half of patients to stop taking acid-suppressing medications.13PubMed. Non-pharmacological approaches in gastroesophageal reflux disease: Evidence-based dietary and lifestyle interventions The key word is “systematic.” Random avoidance of foods you have heard might be bad is less effective than keeping a food diary, identifying your actual triggers, and eliminating those specifically.
If you suspect ginger ale is bothering you, the most productive approach is to cut it out for a few weeks and see what happens. If you feel better, you have your answer. If you miss the ginger flavor, switching to ginger tea or a small piece of candied ginger gives you a test of whether it is the carbonation, the sugar, or the ginger itself that your esophagus objects to.
Flat Ginger Ale and Other Folk Remedies
A common home remedy involves letting ginger ale go flat before drinking it, supposedly capturing ginger’s benefits while avoiding the carbonation issue. On paper, this makes some sense: you eliminate the gas that distends the stomach and weakens the LES. In practice, you are left with a room-temperature sugar solution with trace amounts of ginger compounds, which is a less efficient way to get ginger’s effects than simply making ginger tea. The tradition of flat ginger ale for upset stomachs comes from an era when ginger ales were brewed with real ginger root and contained considerably more of the active compounds than modern mass-produced versions do.
Another common belief is that the alkalinity of ginger can neutralize stomach acid. Ginger root is mildly acidic to neutral in pH, not alkaline. More importantly, commercial ginger ale typically has a pH in the range of 2.5 to 3.5 due to added citric acid, making it quite acidic. Drinking something that acidic while trying to manage acid reflux is counterproductive by design. Even if the ginger component had mild acid-buffering properties, the overall drink is still acidic and carbonated.
When to Move Beyond Kitchen Remedies
Occasional heartburn after a big meal or a trigger food is normal and does not necessarily mean you need medical treatment. But GERD is a chronic condition where reflux happens frequently enough to cause symptoms or damage to the esophageal lining. If you are reaching for ginger ale multiple times a week because of persistent heartburn, that pattern itself suggests you should talk to a doctor rather than self-treating with a beverage that may be making things worse.
The ACG guidelines emphasize several lifestyle changes with better evidence than any single food or drink: losing weight if you carry extra pounds, elevating the head of your bed, avoiding meals close to bedtime, and cutting back on alcohol and tobacco.11PubMed Central. ACG Clinical Guideline: Guidelines for the Diagnosis and Management of Gastroesophageal Reflux Disease These interventions address the mechanical and physiological drivers of reflux rather than trying to manage symptoms one sip at a time. For people whose reflux persists despite lifestyle changes, medications like proton pump inhibitors remain the standard treatment, and no amount of ginger in any form is a substitute for them when they are warranted.
