Ginger ale is one of the most common home remedies people reach for when their stomach is upset, but most commercial ginger ale contains almost no real ginger. A standard can of Canada Dry lists “less than 2%” ginger extract alongside high fructose corn syrup, carbonated water, and natural flavors. That tiny amount falls far short of the roughly 1,000 milligrams (1 gram) of ginger per day that clinical trials have found effective for reducing nausea.
So while ginger itself has genuine stomach-settling properties, the drink most people grab from the fridge is essentially sugar water with a hint of ginger flavor.
What Ginger Actually Does for Your Stomach
Real ginger contains active compounds, primarily gingerol and shogaol, that interact with nerve fibers lining the esophagus and stomach. These compounds initially stimulate the nerve endings, then desensitize them, which appears to dampen the signals that trigger nausea. Ginger also influences stomach motility, helping food move through your digestive system more efficiently rather than sitting and causing discomfort.
The evidence is strongest for pregnancy-related nausea. In randomized controlled trials, women who took 250 mg of ginger powder four times daily saw a 63% decrease in nausea compared to 42% with a placebo. Vomiting dropped even more dramatically: one trial found that by day six, only 33% of women taking ginger were still vomiting compared to 80% on placebo. Ginger has also shown benefits for motion sickness and chemotherapy-related nausea, though the quality of evidence varies.
The key detail across these studies is dosage. Effective results came from 500 to 1,000 mg of actual ginger per day, taken in divided doses. That’s a meaningful amount of the real root or a concentrated extract, not the trace flavoring in a soft drink.
Why Most Ginger Ale Falls Short
Canada Dry and Schweppes, the two best-selling ginger ale brands, list ginger extract below the 2% threshold on their ingredient labels. Taste testers consistently describe these drinks as overwhelmingly sweet with only a faint ginger aftertaste. Schweppes adds artificial flavoring to boost its ginger impression. Neither brand discloses how many milligrams of ginger or gingerol a serving contains, but given the labeling, it’s vanishingly small compared to the gram-per-day doses used in research.
A few craft brands do use real ginger in noticeable amounts. Bruce Cost makes unfiltered ginger ale from fresh ginger root, and Reed’s includes a measurable amount of pressed ginger. Boylan uses real ginger and cane sugar. These taste noticeably spicy and pungent, nothing like the mild sweetness of mainstream brands. If you’re set on drinking ginger ale for your stomach, these are the only ones likely to deliver a pharmacologically relevant dose, though even then, you’d need to drink a fair amount.
How Ginger Ale Could Make Things Worse
The two main ingredients in mainstream ginger ale, sugar and carbonation, can each aggravate stomach trouble in their own way.
A 12-ounce can of regular Canada Dry contains high fructose corn syrup as its second ingredient. For people with sensitive digestion, high fructose corn syrup is a known trigger for bloating, cramping, and diarrhea. Johns Hopkins Medicine specifically flags it as a problem for people with irritable bowel syndrome, and even in otherwise healthy people, a large sugar load on an already upset stomach can pull water into the intestines and worsen loose stools.
Carbonation is more nuanced. The bubbles can cause gas and a feeling of fullness, which is the last thing you want if you’re already bloated or nauseous. However, one clinical study found that carbonated water actually improved symptoms in people with functional dyspepsia (chronic indigestion), reducing their symptom scores significantly compared to tap water. The difference may come down to the type of stomach problem: if your issue is trapped gas or bloating, carbonation could make it worse, while if you’re dealing with sluggish digestion, it might help move things along.
What Works Better Than Ginger Ale
If you want ginger’s real benefits for your stomach, skip the soda and go straight to a form that delivers an actual dose of the root.
- Ginger tea. Peel a thumb-sized piece of fresh ginger, slice it thinly, and steep it in hot water for 5 to 10 minutes. Fresh ginger root is inexpensive and widely available. You can also buy pre-made ginger tea bags, though these vary in potency.
- Ginger chews or candies. Look for brands in the natural foods aisle that list ginger as a primary ingredient. Low-sugar versions are better if your stomach is already irritated.
- Powdered ginger capsules. These are the closest to what clinical trials actually tested. A 250 mg capsule taken four times a day matches the most common study protocol.
- Ginger shots. Concentrated ginger juice, sometimes mixed with lemon, available at many grocery stores. These deliver a potent dose in a small volume.
Cleveland Clinic gastroenterologists recommend having ginger in small amounts spread throughout the day rather than one large dose. This matches the clinical trial approach of dividing the daily amount into four servings.
When You’re Dealing With a Stomach Bug
If your nausea comes with vomiting and diarrhea from a stomach virus, hydration matters more than ginger. You’re losing fluids and electrolytes, and a sugary soda replaces neither effectively. An oral rehydration solution or a sports drink will do far more to help you recover.
Pediatric guidelines from Nemours KidsHealth do mention flat ginger ale as one option for children who are vomiting, but it’s listed alongside oral rehydration solutions, ice chips, clear broth, and diluted juice. The emphasis is on getting any tolerable fluid into a child who won’t drink anything else. Flat is the key word: letting the carbonation dissipate removes one potential source of further stomach irritation.
There’s a reason your grandmother gave you ginger ale when you were sick, and it wasn’t wrong exactly. The ritual of sipping something cool and mildly flavored, staying hydrated, and resting does help. But the ginger ale itself was mostly a vehicle for fluids and comfort. If you want the actual anti-nausea effects of ginger, real ginger in a meaningful dose is the way to get them.
