Ginger ale is one of the most common home remedies people reach for when their stomach is off, but most commercial ginger ale does very little to help. The drink contains so little real ginger that it falls far short of the amounts shown to relieve nausea in clinical research. At the same time, its sugar content and carbonation can actually make certain stomach symptoms worse.
Why Ginger Works but Ginger Ale Mostly Doesn’t
Real ginger contains active compounds that block several chemical pathways involved in nausea and vomiting. These compounds reduce levels of serotonin in the gut and block the receptors that trigger the vomiting reflex. They also slow the release of substance P, another signaling molecule that contributes to nausea, and they help normalize delayed stomach emptying, which is a common cause of that heavy, queasy feeling after eating.
Clinical trials consistently show these effects require a meaningful dose. Studies on motion sickness found that 1 to 2 grams of powdered ginger root effectively reduced nausea and stomach contractions. Even a smaller extract of 250 milligrams prevented seasickness in about 78% of volunteers. For children, 1.25 grams daily outperformed a standard anti-nausea medication at preventing vomiting.
The problem is that most commercial ginger ales contain only “natural flavors” or trace amounts of ginger extract. Even brands that list real ginger as an ingredient, like Reed’s, don’t disclose milligram amounts on the label. The ginger in a typical can of Canada Dry or Schweppes is a flavoring, not a therapeutic dose. You would likely need to drink an unrealistic quantity to approach even the lowest effective dose studied in trials.
How Sugar and Carbonation Can Backfire
A standard 12-ounce can of ginger ale contains around 32 to 36 grams of sugar, often from high fructose corn syrup. That much fructose can pull water into the intestines through an osmotic effect, increasing the liquidity of what’s moving through your digestive tract and speeding up gut motility. In plain terms, it can make diarrhea worse. Research has shown that roughly half of people with sensitive stomachs experience worsened symptoms after consuming 40 grams of fructose, an amount found in just two cans of regular soda.
Carbonation adds another layer. When you’re already dealing with gas, bloating, or indigestion, the carbon dioxide in fizzy drinks introduces more gas into your stomach, which can increase pressure and discomfort. That’s why some people are told to let ginger ale go flat before drinking it. But once you remove the fizz and account for the negligible ginger content, you’re essentially left with sugar water.
What the Mayo Clinic Actually Says
The Mayo Clinic does list ginger ale among options for nausea, recommending small sips of “cold, clear, carbonated or sour drinks, such as ginger ale, lemonade and water.” The key detail here is “small sips.” The recommendation is about gentle hydration and the soothing effect of cold, clear liquids on a churning stomach, not about ginger ale’s medicinal properties specifically. When you’re vomiting or struggling to keep anything down, tiny sips of almost any tolerable clear liquid help prevent dehydration, and if ginger ale is all you can tolerate, that matters more than what’s in it.
Better Ways to Get Ginger’s Benefits
If you want the actual anti-nausea effects that ginger provides, you need to get closer to the doses used in research. Several options deliver far more ginger than a can of soda:
- Ginger capsules or supplements: These typically contain 250 to 500 milligrams of ginger extract per capsule, putting you in the range that clinical studies have found effective. Two to four capsules gets you to the 1-gram threshold.
- Fresh ginger tea: Steeping a one-inch piece of peeled, sliced fresh ginger in hot water for 10 minutes creates a tea with a meaningful concentration of the active compounds. You can add honey if the taste is too sharp.
- Ginger chews or candies made with real ginger: Some brands use enough real ginger that a few pieces deliver a noticeable dose. Check the label for actual ginger content rather than just ginger flavoring.
- Crystallized ginger: Small pieces of dried, sugar-coated ginger root. A few pieces contain more ginger than an entire can of ginger ale, though they do come with added sugar.
For straight hydration during a stomach bug, plain water, diluted broth, or an oral rehydration solution will rehydrate you without the sugar load. If plain water feels harsh on your stomach, keeping it cold and taking small, frequent sips is more helpful than switching to soda.
When Ginger Ale Still Makes Sense
None of this means ginger ale is forbidden when you feel sick. If it’s the only thing that sounds tolerable and you’re struggling to drink anything at all, sipping a small amount is better than drinking nothing. The ritual of it, something your parent or grandparent probably handed you as a kid, can provide genuine comfort, and comfort has real value when you’re miserable. Just know that the benefit is coming from hydration and familiarity, not from the ginger itself. For actual nausea relief, real ginger in a concentrated form is a different experience entirely.
