Tonic water may provide mild relief for upset stomachs due to its quinine content, but it’s not a proven remedy and should be consumed in moderation.
An upset stomach can strike at any time, leaving you searching for quick relief. While many reach for tonic water as a home remedy, does it actually work? This article explores the science behind tonic water and stomach discomfort, plus better alternatives for digestive relief.
Why People Use Tonic Water for Stomach Issues
Tonic water contains quinine, a compound historically used to treat malaria. Some believe its bitter properties may help digestive problems. The carbonation in tonic water might also provide temporary relief by:
- Encouraging burping to release gas pressure
- Creating a soothing sensation in the stomach
- Potentially helping neutralize stomach acid (though evidence is limited)
The Quinine Factor
Quinine gives tonic water its distinctive bitter taste. While used medicinally in higher doses, the small amount in commercial tonic water (83 mg per liter max per FDA regulations) likely provides minimal therapeutic benefit. Some people report it helps with:
- Mild nausea
- Stomach cramps
- Digestive discomfort
However, a 2015 study found no significant evidence supporting quinine’s effectiveness for digestive issues at tonic water concentrations.
Potential Downsides of Using Tonic Water
While generally safe in moderation, tonic water has some drawbacks:
| Concern | Details |
|---|---|
| High Sugar Content | Regular tonic water contains about 32g sugar per 12oz – more than soda |
| Artificial Sweeteners | Diet versions often contain aspartame or other sugar substitutes |
| Quinine Sensitivity | Some people experience nausea or headaches from quinine |
| Carbonation Issues | Can worsen bloating in some individuals |
Better Alternatives for Stomach Relief
For more effective upset stomach remedies, consider these options:
1. Ginger-Based Solutions
Ginger has strong scientific backing for nausea relief. Try:
- Fresh ginger tea (steep sliced ginger in hot water)
- Ginger chews or candies
- Ginger ale made with real ginger (check labels)
Our best blender for soups and smoothies can help make fresh ginger remedies easily.
2. Peppermint Tea
Peppermint relaxes digestive tract muscles. A 2019 study showed peppermint oil capsules significantly reduced IBS symptoms.
3. The BRAT Diet
When recovering from stomach issues, try bland foods:
- Bananas
- Rice
- Applesauce
- Toast
4. Chamomile Tea
Chamomile’s anti-inflammatory properties can soothe stomach muscles. It’s particularly helpful for stress-related digestive issues.
When to See a Doctor
While tonic water and home remedies can help mild cases, seek medical attention if you experience:
- Severe or persistent pain
- Blood in vomit or stool
- High fever with stomach issues
- Signs of dehydration
- Symptoms lasting more than 48 hours

The Bottom Line on Tonic Water
Tonic water might provide temporary relief due to its carbonation, but there’s little evidence quinine helps at beverage concentrations. The high sugar content may actually worsen some stomach issues. For better results, try proven remedies like ginger, peppermint, or chamomile, and stick to clear, non-carbonated fluids if nausea is severe.
