Acid reflux and heartburn are extremely common experiences. Research suggests that 18-28% of adults in North America experience GERD symptoms, with approximately 20% of the U.S. population affected. If you’ve ever dealt with that uncomfortable burning sensation in your chest or that unpleasant taste creeping up into your throat, you know how disruptive it can be.
I used to experience these symptoms myself. They seemed to strike at the worst possible moments—before important meetings, during family dinners, at social gatherings. I found myself constantly reaching for antacids, keeping them in my car, desk drawer, and medicine cabinet. I didn’t want to rely on these forever, so I started researching other approaches.
What I discovered challenged some of my assumptions about what might actually be going on. In this article, I’ll share four approaches that some people find supportive for occasional heartburn discomfort—but first, it helps to understand a bit about why heartburn happens in the first place.
Important: If you experience heartburn more than twice a week, have difficulty swallowing, or notice symptoms worsening despite lifestyle changes, please consult your healthcare provider. Persistent symptoms may indicate GERD (gastroesophageal reflux disease) or other conditions that warrant professional evaluation.
Understanding What May Contribute to Heartburn
Before exploring remedies, it’s helpful to understand the conventional view of heartburn and some alternative perspectives.
The Conventional View
According to mainstream medical understanding, heartburn occurs when stomach acid flows backward (refluxes) into the esophagus. The lower esophageal sphincter (LES)—a ring of muscle between your esophagus and stomach—normally stays closed to prevent this backflow. When the LES relaxes inappropriately or weakens, acid can escape upward, causing that familiar burning sensation.
The esophageal lining isn’t designed to handle highly acidic contents the way the stomach lining is, which is why even small amounts of acid in the wrong place can cause significant discomfort.
Common triggers identified in research include fatty or spicy foods, chocolate, caffeine, alcohol, smoking, obesity, and lying down after eating.
An Alternative Perspective: Could Low Stomach Acid Play a Role?
Here’s where things get interesting. While the conventional approach focuses on reducing stomach acid, some practitioners in the integrative and functional medicine community have explored a different theory.
Dr. Steven Sandberg-Lewis, a naturopathic gastroenterologist, has observed in his clinical practice that many patients presenting with reflux symptoms actually test for having lower-than-expected stomach acid levels. Dr. Jonathan Wright, MD, author of “Why Stomach Acid Is Good for You,” has reported similar observations.
The theory goes something like this: when stomach acid levels are insufficient, food may not break down as efficiently. This could potentially lead to fermentation of food in the stomach, producing gases that increase pressure. That increased pressure might push whatever acid is present up through the LES and into the esophagus.
Important context: This theory, while discussed in integrative medicine circles, hasn’t been validated through large-scale clinical trials. If you’re curious about your own stomach acid levels, this is something to explore with a qualified healthcare provider who can recommend appropriate testing.
The remedies below are organized with this alternative perspective in mind—the first three approaches some people try to support digestion, while the fourth offers a more conventional approach for temporary relief.
Remedy #1: Apple Cider Vinegar (ACV)
How Some People Use It
Apple cider vinegar has been a popular folk remedy for various digestive complaints for generations. The idea behind using ACV for heartburn relates to the theory that adding a small amount of acid before or during meals might support the stomach’s digestive process.
Vinegar has a pH of around 2-5, depending on the type. Some people believe that consuming a diluted amount before meals may help support normal digestive function.
What the Research Says
Here’s where I need to be transparent: according to Harvard Health, there is currently no published research in medical journals specifically examining whether apple cider vinegar helps with heartburn. The evidence for this remedy is primarily anecdotal—meaning it comes from personal reports rather than controlled studies.
A 2020 review in PMC noted that while apple cider vinegar has been studied for blood sugar management, its specific effects on heartburn haven’t been systematically investigated.
How to Try It (If You Choose)
If you’d like to experiment with this approach:
- Mix 1-2 teaspoons of raw, unfiltered apple cider vinegar (like Bragg’s) in a full glass of water
- Some people drink this before meals
- If you experience discomfort, this approach may not be right for you
Cautions: Never drink undiluted vinegar—it can damage tooth enamel and irritate the esophagus. If you’re taking medications, check with your healthcare provider first, as vinegar may interact with certain drugs, including insulin and diuretics.
Remedy #2: Lemon Juice
The Idea Behind It
Lemon juice, with a pH of around 2-3, is more acidic than vinegar. Some people try lemon juice based on the same theory as ACV—that adding acidic content before meals might support digestive processes.
How Some People Use It
- Squeeze the juice of half a lemon into 4-6 ounces of water
- Drink before or with meals
- Some people add a small amount of raw honey for taste
Important Considerations
Like apple cider vinegar, there’s limited scientific research specifically examining lemon juice for heartburn relief. This remedy is based primarily on traditional use and anecdotal reports.
Caution: The high acidity can erode tooth enamel over time. Consider drinking through a straw and rinsing your mouth with plain water afterward. If acidic foods typically trigger your symptoms, this approach may not be appropriate for you.
Remedy #3: Betaine HCl Supplementation
What Is Betaine HCl?
Betaine hydrochloride is a supplemental form of hydrochloric acid—the same acid your stomach naturally produces. It’s been used in integrative medicine settings for people who may have insufficient stomach acid production (a condition sometimes called hypochlorhydria).
What Research Shows
A 2013 study published in Molecular Pharmaceutics found that 1500 mg of betaine HCl significantly lowered gastric pH (making it more acidic) in healthy volunteers with drug-induced low stomach acid. The effect was rapid—occurring within about 6 minutes—but temporary, lasting approximately 73 minutes.
A 2020 review in Integrative Medicine explored the evidence for betaine HCl supplementation, noting that while the integrative medicine community has long recommended it for hypochlorhydria, published data specifically examining its effects on digestive outcomes remains limited.
Important Considerations
This is not a remedy for everyone. Betaine HCl is a more serious intervention than kitchen-cabinet remedies:
- Do NOT use if you are taking: PPIs (proton pump inhibitors), H2 blockers, NSAIDs, aspirin, or corticosteroids. Combining betaine HCl with these medications could potentially cause harm.
- Do NOT use if you have: Active ulcers, gastritis, or a history of stomach bleeding
- Work with a qualified practitioner who can help you determine if this approach is appropriate and guide proper dosing
If you’re interested in exploring whether low stomach acid might be a factor for you, consider working with a healthcare provider who can recommend appropriate testing, such as the Heidelberg stomach acid test.
For those who do work with a practitioner on this approach, betaine HCl is typically taken at the beginning of protein-containing meals, not with snacks or low-protein meals.

Remedy #4: Baking Soda (For Temporary Relief)
If you’ve tried the approaches above and are still experiencing discomfort—or if you need more immediate relief—baking soda offers a different approach that aligns more closely with conventional thinking.
How It Works
Baking soda (sodium bicarbonate) is alkaline, meaning it can neutralize stomach acid. The NCBI StatPearls resource confirms that oral sodium bicarbonate is approved for relieving heartburn, acid indigestion, and upset stomach.
When baking soda meets hydrochloric acid in your stomach, a chemical reaction occurs that produces water, salt, and carbon dioxide gas (which is why you might burp after taking it).
How to Use It
- Mix ½ teaspoon of baking soda in ¼ cup (4 oz) of water
- Drink the mixture
- Wait 5-7 minutes
- If discomfort persists, you can repeat
Important Cautions
While baking soda is generally considered safe for occasional use, there are important limitations:
- Not for regular use: The FDA recommends not using baking soda for more than 2 weeks without consulting a doctor
- High sodium content: Each teaspoon contains significant sodium, which may be problematic for people with high blood pressure, heart disease, or kidney issues
- Potential for overuse problems: Excessive use can lead to metabolic alkalosis—a serious condition where the body becomes too alkaline. Case reports have documented this risk.
- Drug interactions: Baking soda can affect the absorption of certain medications
Who should avoid: People on sodium-restricted diets, those with kidney disease, high blood pressure, or heart conditions. Pregnant women should consult their healthcare provider before use.
Conventional Treatment Options
While this article focuses on natural approaches, it’s important to acknowledge that effective conventional treatments exist. If you experience frequent heartburn, your healthcare provider may recommend:
- Over-the-counter antacids (like Tums or Rolaids) for occasional symptoms
- H2 blockers (like famotidine) which reduce acid production
- Proton pump inhibitors (PPIs) for more persistent symptoms
These medications have been extensively studied and can be very effective. However, like any treatment, they come with their own considerations—particularly with long-term use. This is something to discuss with your healthcare provider based on your individual situation.
Lifestyle Approaches That May Help
Beyond specific remedies, research supports several lifestyle modifications for managing occasional heartburn:
- Avoid lying down for 2-3 hours after eating — This gives your stomach time to empty and reduces the likelihood of reflux
- Elevate the head of your bed — A 6-8 inch elevation can help gravity keep stomach contents where they belong
- Identify your personal triggers — Common culprits include fatty foods, spicy foods, chocolate, caffeine, alcohol, and citrus, but triggers vary by individual
- Eat smaller, more frequent meals — Large meals increase stomach pressure
- Maintain a healthy weight — Excess abdominal weight can put pressure on the stomach
- Don’t smoke — Smoking weakens the lower esophageal sphincter
When to See a Doctor
Please consult a healthcare provider if you experience:
- Heartburn more than twice a week
- Symptoms that persist despite over-the-counter treatments or lifestyle changes
- Difficulty swallowing or pain when swallowing
- Unintentional weight loss
- Nausea or vomiting (especially if vomit appears like coffee grounds)
- Black or bloody stools
- Chest pain (especially if accompanied by arm pain, jaw pain, or shortness of breath—seek emergency care)
Persistent acid reflux can lead to complications, including esophagitis, strictures, and Barrett’s esophagus, which increases the risk of esophageal cancer. Early evaluation and appropriate treatment are important.
Supporting Your Digestive Health Long-Term
Quick remedies can be helpful for occasional discomfort, but if you’re dealing with recurring symptoms, it may be worth exploring what’s happening at a deeper level.
Some people find that working on overall digestive health—through approaches like dietary changes, stress management, addressing potential gut infections, and supporting healthy stomach acid levels—can make a meaningful difference over time.
If you’re interested in learning more about the potential connection between low stomach acid and reflux symptoms, our article Hypochlorhydria: 3 Common Signs of Low Stomach Acid explores this topic in depth.
Some people also choose to support their digestive function with supplements like digestive enzymes or betaine HCl (under appropriate guidance). These aren’t quick fixes, but rather part of a broader approach to supporting healthy digestion.
Frequently Asked Questions
Is apple cider vinegar scientifically proven to help heartburn?
Currently, there is no published clinical research specifically examining apple cider vinegar for heartburn relief. The evidence is primarily anecdotal. While many people report it helps them, others find it worsens their symptoms. If you try it, dilute it well (1-2 teaspoons in a full glass of water) and discontinue if it causes discomfort.
How quickly does baking soda work for heartburn?
Baking soda typically provides relief within 5-15 minutes as it neutralizes stomach acid. However, it’s intended only for occasional use. If you need frequent relief, consult your healthcare provider about appropriate treatment options.
Can low stomach acid really cause heartburn?
This is a theory explored in integrative medicine, though it hasn’t been validated through large-scale clinical trials. The idea is that insufficient stomach acid may lead to incomplete digestion and increased pressure in the stomach, potentially contributing to reflux. If you’re curious, work with a qualified practitioner who can recommend appropriate testing.
Is betaine HCl safe to take?
Betaine HCl can be appropriate for some individuals but is contraindicated for others—particularly those taking PPIs, H2 blockers, NSAIDs, or those with active ulcers or gastritis. It’s best used under the guidance of a qualified healthcare practitioner who can help determine if it’s appropriate for your situation.
What’s the difference between occasional heartburn and GERD?
Occasional heartburn—happening once or twice a month—is common and usually manageable with lifestyle changes or occasional remedies. GERD (gastroesophageal reflux disease) is diagnosed when reflux symptoms occur more than twice weekly and/or cause complications. GERD typically requires more comprehensive treatment and medical supervision.
Should I take antacids or try natural remedies?
This depends on your individual situation. Over-the-counter antacids are generally effective and well-studied for occasional heartburn. Natural approaches may appeal to those who prefer to try alternatives first or who are curious about addressing underlying factors. There’s no one-size-fits-all answer—what matters is finding an approach that works for you and seeking medical evaluation if symptoms persist.
Key Takeaways
- Occasional heartburn is extremely common, affecting approximately 20% of the U.S. adult population
- Natural approaches like apple cider vinegar and lemon juice are based primarily on traditional use and anecdotal reports rather than clinical research
- Betaine HCl supplementation has some research support, but should only be used under practitioner guidance and is contraindicated for people taking certain medications
- Baking soda offers effective temporary relief, but should be used only occasionally and avoided by those with certain health conditions
- Lifestyle modifications—including avoiding late meals, elevating the head of the bed, and identifying personal triggers—have research support
- Persistent symptoms (more than twice weekly) warrant medical evaluation to rule out GERD or other conditions
