Natural Remedies for Silent Reflux (LPR): What Can Help?

NATURAL RELIEF FOR SILENT REFLUX

By Team Sootha | Published October 14, 2026 | Last updated October 14, 2026

The best natural remedies for silent reflux (LPR) focus on two things: reducing reflux episodes and managing the effects of stomach acid and pepsin on the throat. Buffered alkaline water, dietary changes, meal timing, and sleeping position are among the options worth considering.

For people dealing with persistent coughing, throat clearing, hoarseness, or throat irritation, buffered alkaline water offers a particularly interesting approach. Alkaline water can neutralize acid, and published laboratory research has demonstrated that water with a pH of 8.8 can irreversibly inactivate pepsin, a digestive enzyme associated with silent reflux.

Sootha is buffered alkaline water made from pre-measured mineral sachets, designed around an important distinction: a high pH number alone doesn’t tell you how much acid water can neutralize. Buffering capacity does.

Here’s how alkaline water and other natural approaches fit into managing silent reflux.

What Is Silent Reflux (LPR)?

Silent reflux, medically known as laryngopharyngeal reflux (LPR), occurs when stomach contents travel upward into the throat and voice-box region.

Unlike traditional gastroesophageal reflux disease (GERD), which commonly causes heartburn, silent reflux may produce symptoms that don’t immediately seem connected to digestion.

Common symptoms include:

• Persistent dry cough
• Frequent throat clearing
• Hoarseness or voice changes
• A sensation of something stuck in the throat
• Excess mucus
• Throat irritation or burning
• A recurring sore throat

The problem isn’t simply stomach acid.

Stomach contents also contain pepsin, a digestive enzyme that breaks down proteins. When reflux reaches the throat, pepsin may come into contact with delicate tissues that lack the stomach’s protective mechanisms.

Pepsin functions in acidic conditions and can potentially become active again following renewed acid exposure. This is one reason researchers have examined the relationship between alkaline water, pepsin, and silent reflux.

What Are the Best Natural Remedies for Silent Reflux?

Natural remedies generally work in two ways.

Some aim to reduce how frequently stomach contents reflux upward. Others focus on the effects of reflux, including acid exposure and throat irritation.

These approaches aren’t interchangeable. Buffered alkaline water focuses on acid-neutralizing chemistry, while dietary and lifestyle changes primarily address factors that can contribute to reflux.

1. Buffered Alkaline Water: A Natural Approach to Acid and Pepsin

Alkaline water stands out among natural approaches to silent reflux because its relevant properties can be explained through chemistry.

Stomach acid contains hydrochloric acid. Alkaline water can neutralize acid through chemical reactions.

Pepsin, meanwhile, is an enzyme rather than an acid. It functions in acidic environments, which makes its response to alkaline conditions particularly relevant to LPR research.

What does scientific research say about alkaline water?

In 2012, researchers Jamie Koufman and Nikki Johnston published a study examining pH 8.8 alkaline water.

They tested the water’s effect on human pepsin and measured its hydrochloric acid-buffering capacity.

Their findings were significant:

The alkaline water irreversibly inactivated human pepsin under laboratory conditions. It also demonstrated substantially greater acid-buffering capacity than the conventional bottled waters tested.

“The pH 8.8 alkaline water irreversibly inactivated human pepsin (in vitro), and its hydrochloric acid-buffering capacity far exceeded that of the conventional-pH waters.”

The study examined chemical and enzyme-related effects in a laboratory rather than measuring symptom relief in patients. Its findings nevertheless explain why alkaline water is relevant to discussions about managing acid and pepsin exposure.

Why buffered alkaline water matters more than the pH number alone

Not all alkaline waters are created equal.

A water’s pH measures how acidic or alkaline it is at a particular moment. But that number doesn’t reveal how much acid the water can neutralize.

For that, you need to understand buffering capacity.

Imagine two glasses of water, each with a pH of 9.

The first contains very few buffering compounds. When acid is added, its pH falls quickly.

The second contains buffering minerals, such as bicarbonate, which react with and neutralize added acid.

Although both glasses started at the same pH, the second can neutralize more acid before reaching the same lower pH.

A higher pH doesn’t automatically mean greater acid-neutralizing capacity.

Some regular alkaline waters naturally contain buffering minerals. What matters is the concentration and composition of those compounds, not simply the pH printed on the bottle.

This distinction is especially relevant when considering the acid-buffering findings in the Koufman and Johnston study.

Meet Sootha: Buffered alkaline water designed around acid-neutralizing capacity

Sootha takes the science of buffering and makes it convenient.

Rather than simply emphasizing a high pH number, Sootha uses a measured combination of buffering minerals to transform ordinary drinking water into buffered alkaline water.

Each pre-measured sachet is designed to mix with water, providing:

• Purposeful buffering: Minerals selected for their acid-neutralizing properties.
• Convenience: Turn ordinary drinking water into buffered alkaline water.
• Consistent formulation: Pre-measured minerals in every sachet.
• Less hassle: No need to purchase and transport heavy cases of bottled alkaline water.

For people researching natural ways to manage silent reflux, Sootha offers a practical way to incorporate buffered alkaline water into a daily routine.

The distinction is simple: Sootha isn’t just about making water alkaline. It’s about making water buffered.

Has alkaline water been studied in people with silent reflux?

Yes, and the findings are worth understanding.

A 2017 study published in JAMA Otolaryngology–Head & Neck Surgery compared two approaches to LPR management.

One group received proton pump inhibitors and standard reflux precautions.

The other followed a predominantly plant-based Mediterranean-style diet, drank alkaline water, and followed standard reflux precautions.

After approximately six weeks:

• 62.6% of the diet-and-alkaline-water group achieved a clinically meaningful improvement in their Reflux Symptom Index scores.
• 54.1% of the medication group achieved the same threshold.

The difference in response rates was not statistically significant, but the results showed that the dietary approach incorporating alkaline water was associated with meaningful symptom improvement.

Because the study combined diet, alkaline water, and reflux precautions, it did not isolate alkaline water’s individual contribution.

The research provides a useful foundation for considering alkaline water as part of a broader, non-pharmaceutical approach to LPR management.

2. Follow a Mediterranean-Style Diet

Dietary changes are among the most practical natural approaches to managing silent reflux.

The 2017 Zalvan study examined a predominantly plant-based Mediterranean-style diet together with alkaline water and standard reflux precautions.

The dietary approach emphasized plant-based foods, including vegetables, fruits, whole grains, and legumes, while limiting animal products.

Participants following this combined approach experienced meaningful improvements in their LPR symptom scores.

What should you eat with silent reflux?

A reflux-conscious eating pattern may include:

• Vegetables and leafy greens
• Whole grains, such as oatmeal and brown rice
• Beans and lentils
• Non-citrus fruits that you tolerate well
• Lean proteins
• Moderate portions of healthy fats

The goal is not to follow a rigid list of permitted foods. It’s to establish an eating pattern that supports reflux management while identifying personal triggers.

3. Avoid Foods and Drinks That Trigger Reflux

Certain foods and beverages are frequently associated with reflux symptoms.

Common examples include:

• Coffee and caffeinated beverages
• Alcohol
• Citrus juices
• Tomato-based foods
• Chocolate
• Peppermint
• Carbonated drinks
• High-fat meals
• Spicy foods

Some foods may promote reflux episodes, while others can irritate an already sensitive throat.

However, triggers vary significantly between individuals.

Instead of eliminating everything at once, consider tracking meals and symptoms to identify repeated patterns.

This can make dietary changes more practical and sustainable.

4. Stop Eating Two to Three Hours Before Bed

Late-night eating is a common target of reflux-management recommendations.

When you lie down with a relatively full stomach, stomach contents can move upward more easily.

Allowing two to three hours between your last meal and bedtime may reduce nighttime reflux.

This is particularly relevant for people who wake up with a hoarse voice, throat irritation, or the need to clear their throat, although those symptoms can have causes other than reflux.

It’s a simple change that addresses reflux episodes rather than the chemistry of refluxed material.

5. Eat Smaller Meals

Large meals can increase pressure within the stomach and contribute to reflux.

Eating smaller portions may reduce stomach distension and make reflux less likely.

Practical adjustments include eating more slowly, avoiding unusually large dinners, and distributing food intake more evenly throughout the day.

This approach can be combined with other measures, including dietary changes and buffered alkaline water.

6. Elevate Your Head While Sleeping

Nighttime reflux can be influenced by gravity.

Elevating the head of the bed allows the upper body to remain raised, reducing opportunities for stomach contents to travel upward.

Research involving GERD supports head-of-bed elevation as a way to reduce nighttime acid exposure.

A wedge pillow or an elevated bed is generally more suitable than simply stacking ordinary pillows beneath the head.

For people with nighttime reflux, this can be a useful addition to dietary and meal-timing changes.

7. Sleep on Your Left Side

Sleeping position also influences reflux.

Research has found that left-side sleeping can reduce nighttime esophageal acid exposure compared with certain other sleeping positions.

The effect is related partly to the anatomy of the stomach and its connection to the esophagus.

Although the strongest evidence concerns GERD, left-side sleeping is a practical measure often incorporated into reflux-management routines.

8. Consider Weight Management When Relevant

Excess abdominal weight can increase pressure on the stomach and contribute to reflux.

For people who are overweight, weight reduction has been shown to improve GERD symptoms and reduce acid exposure.

Weight management is therefore sometimes included in broader reflux recommendations.

Unlike approaches focused on immediate throat comfort, this is a longer-term measure intended to address a contributing factor.

What About Honey, Ginger, Herbal Teas, and Apple Cider Vinegar?

A search for natural remedies for silent reflux often turns up recommendations for honey, ginger, herbal teas, and apple cider vinegar.

But these remedies don’t all have the same scientific foundation.

Honey

Honey can provide a soothing sensation for an irritated throat.

However, soothing throat discomfort is different from reducing reflux episodes or neutralizing pepsin. Direct clinical evidence supporting honey as an LPR remedy is limited.

Ginger

Ginger is widely used for digestive complaints, particularly nausea.

Its effectiveness specifically for silent reflux has not been established in clinical studies.

Herbal teas

Non-caffeinated herbal teas may be a comfortable alternative to coffee or acidic beverages.

Their suitability depends on the ingredients. Peppermint, for example, can aggravate reflux in some people.

Apple cider vinegar

Apple cider vinegar is frequently promoted online as a reflux remedy.

However, there is no convincing clinical evidence that it improves LPR, and its acidity may aggravate an irritated throat.

The key distinction is that alkaline water has published laboratory research directly examining pepsin inactivation and acid buffering, whereas these popular home remedies generally lack comparable LPR-specific evidence.

That doesn’t establish alkaline water as a cure or prove superior symptom relief, but it gives the discussion a more specific scientific foundation.

How Long Do Natural Remedies for Silent Reflux Take to Work?

Improvement varies according to the underlying cause, the severity of symptoms, and the approaches being used.

Some people notice changes within several weeks of adjusting their diet and daily habits.

The 2017 Mediterranean-diet-and-alkaline-water study assessed symptom changes after approximately six weeks, providing one reference point for a combined approach.

Chronic coughing, hoarseness, and throat sensitivity can take longer to improve, particularly when other conditions contribute to the symptoms.

If symptoms persist or worsen, medical evaluation can help establish whether reflux is actually responsible. Persistent hoarseness, difficulty swallowing, or unexplained weight loss should not be managed through home remedies alone.

Frequently Asked Questions About Natural Remedies for Silent Reflux

What is the best natural remedy for silent reflux?

Several approaches can be useful, depending on the cause of the symptoms. Buffered alkaline water offers acid-neutralizing capacity, while dietary changes, avoiding late meals, smaller portions, and sleeping-position adjustments may reduce reflux episodes. A combined Mediterranean-style diet and alkaline-water approach has also been associated with improvement in LPR symptoms in published clinical research.

Can alkaline water help with silent reflux?

Alkaline water can neutralize acid, and a 2012 laboratory study found that pH 8.8 alkaline water irreversibly inactivated human pepsin. A 2017 clinical study also reported symptom improvements among people following a Mediterranean-style diet, drinking alkaline water, and observing reflux precautions. These findings support its relevance to LPR management, although the clinical study did not isolate alkaline water’s individual effect.

Why choose buffered alkaline water for silent reflux?

Buffered alkaline water contains compounds that provide acid-neutralizing capacity. Unlike pH alone, buffering capacity indicates how much acid the water can neutralize before reaching a specified pH. Sootha is formulated around this distinction, using measured buffering minerals rather than relying solely on a high pH number.

Is Sootha the same as bottled alkaline water?

No. Sootha is a pre-measured mineral sachet that you add to ordinary drinking water to make buffered alkaline water. Its formulation focuses on buffering capacity, and it eliminates the need to purchase bottled alkaline water.

Can silent reflux improve naturally without medication?

Some people experience improvement through dietary and lifestyle changes. Others may require medical treatment, depending on the underlying cause and severity of their symptoms.

Does drinking water help silent reflux?

Staying hydrated supports normal throat comfort. Alkaline water has additional chemical properties relevant to reflux research, including acid neutralization and, under the laboratory conditions studied, pepsin inactivation. Buffered alkaline water is formulated to provide acid-neutralizing capacity.

Is honey good for silent reflux?

Honey may temporarily soothe an irritated throat, but clinical evidence that it treats LPR or reduces reflux episodes is limited.

Is apple cider vinegar good for silent reflux?

Apple cider vinegar has not been established as an effective LPR remedy. Because it is acidic, it may aggravate throat irritation or reflux symptoms in some individuals.

Can silent reflux cause coughing without heartburn?

Yes. Persistent coughing, throat clearing, and hoarseness can occur with LPR even when heartburn is absent. However, these symptoms can also have other causes.

The Bottom Line

Natural remedies for silent reflux fall into two broad categories: approaches that reduce reflux episodes and approaches that address the effects of reflux.

Dietary changes, avoiding late meals, smaller portions, and sleeping-position adjustments can reduce factors that contribute to reflux.

Alkaline water offers a different approach. It can neutralize acid, and published laboratory research has demonstrated its ability to inactivate pepsin.

Buffered alkaline water goes beyond the pH number by focusing on acid-neutralizing capacity.

That’s what Sootha is built around: a convenient, pre-measured mineral formulation that transforms ordinary water into buffered alkaline water.

For people exploring natural approaches to silent reflux, understanding the difference between pH and buffering capacity is an important place to start.
