What to Drink With Acid Reflux: Best and Worst Choices Explained

What you drink has a more direct impact on acid reflux than most people realise — and for a specific reason that goes beyond simply whether a drink is “acidic.” If you have LPR (laryngopharyngeal reflux) or GERD, acidic and carbonated drinks don’t just cause direct irritation — they can reactivate dormant pepsin that has been deposited on your throat and esophageal lining from previous reflux events. That reactivation is why a single cup of coffee or glass of wine can trigger symptoms hours after what you assumed was a safe meal.

In this article I want to go through the best drinks for acid reflux, explain specifically why certain drinks cause problems (so you understand the mechanism rather than just getting a list), and give you practical alternatives that won’t set your symptoms back.

The approach here applies whether you have GERD with classic heartburn symptoms or LPR with throat symptoms — though for LPR specifically, drink choices are particularly critical because the throat is far more sensitive to pepsin reactivation than the esophagus.

Key Takeaways

• Drinks matter for reflux not just because of acidity but because acidic beverages reactivate dormant pepsin already deposited in your throat and esophageal lining.
• Alkaline water at pH 8.8 or above can irreversibly inactivate pepsin and has an acid-buffering capacity significantly greater than regular water — making it the optimal daily drink for LPR and GERD.
• Plain still water is the safest everyday choice for anyone with reflux and is far preferable to any juice, carbonated drink, or flavoured beverage.
• Coffee — at any pH — reduces lower esophageal sphincter (LES) pressure in both healthy people and GERD patients, making it a consistent reflux trigger regardless of whether it tastes acidic.
• Alcohol reduces LES pressure, stimulates gastric acid secretion, and directly damages the esophageal mucosa — making it one of the worst drinks for reflux regardless of type.
• Carbonated drinks cause a 30–50% reduction in LES pressure through gastric distension, which is why fizzy drinks — even seemingly “alkaline” sparkling water — increase reflux risk.
• Chamomile tea and marshmallow root tea are the best herbal tea options — both have anti-inflammatory properties and are non-acidic, with chamomile specifically supporting a calmer digestive response.
• A large prospective study of 48,308 women found that replacing 2 daily servings of coffee, tea, or soda with water was associated with a meaningful reduction in GERD symptom risk.

The Best Drinks for Acid Reflux

Alkaline Water (pH 8.8+) — The Optimal Choice for LPR

For people with LPR specifically, alkaline water is more than just a safe drink — it has a documented therapeutic mechanism. Research has shown that water at pH 8.8 instantly and irreversibly inactivates human pepsin, rendering it permanently inactive [Koufman & Johnston, The Annals of Otology, Rhinology & Laryngology, 2012]. The same study found that alkaline water has an acid-buffering capacity far exceeding regular bottled water at neutral pH — meaning it can help neutralise acid in the upper digestive tract, not just dilute it.

To put this in practical terms: if you’ve had a reflux event and pepsin has been deposited on your throat lining, a sip of alkaline water may help inactivate that pepsin before it gets reactivated by your next meal. Regular water at pH 6.7–7.4 has no effect on pepsin stability and doesn’t offer this benefit.

Look for still alkaline water with a pH of 8.8 or above — this is available in most supermarkets and health food stores. Brands like Evamor, Essentia, or Hallstein are widely available. Sip it throughout the day and especially after meals and before bed. For LPR, it’s one of the most useful daily habits you can build. I go into more detail on this in my article on alkaline water for LPR.

Plain Still Water

If you can’t access alkaline water, plain still water remains the best default choice. It doesn’t trigger reflux, doesn’t reactivate pepsin, and helps dilute and clear stomach contents. A large prospective study of 48,308 women found that replacing 2 servings per day of coffee, tea, or soda with water was associated with a meaningful reduction in GERD symptom risk [Mehta et al., Clinical Gastroenterology and Hepatology, 2020].

The one caveat is sparkling or carbonated water — even if it has a higher pH, the carbonation itself is problematic for reflux (more on this below). Stick to still water as your everyday default.

Chamomile Tea

Chamomile is the herbal tea I’d most confidently recommend for reflux. It’s non-acidic, anti-inflammatory, and has a long tradition of use for digestive complaints. Chamomile contains compounds with well-documented antispasmodic and anti-inflammatory activity that may help calm the digestive tract and reduce gastric irritation. One well-studied herbal preparation containing chamomile extract was shown to reduce stomach acid output and increase the protective mucus lining of the stomach — outperforming a commercial antacid for secondary acid rebound in one comparison.

For LPR specifically, chamomile is a good evening tea choice — it’s soothing, helps reduce the urge to snack late at night (which is important for avoiding nocturnal reflux), and doesn’t carry the pepsin-reactivating risk of anything acidic. I have a full article on chamomile tea and acid reflux if you want to go deeper on this one.

One practical note: brew it properly. Research on herbal tea preparation shows chamomile should be steeped in near-boiling water for at least 5–10 minutes to extract the beneficial compounds. A 2-minute steep leaves most of the active polyphenols in the bag.

Marshmallow Root Tea

Marshmallow root is probably the most underrated option on this list. It contains high levels of mucilage — a gel-like substance that coats and soothes the mucosal lining of the esophagus and throat. This is why it’s commonly used in cough medicines and throat preparations. For someone with LPR where the throat lining is already irritated and inflamed, the coating effect of marshmallow root tea can provide genuine symptomatic relief while not adding any acidity or reflux risk.

It can be found in most health food stores and is safe to drink daily. Let it steep well to release the mucilage — it should have a slightly thick, slightly slippery quality when brewed correctly. This isn’t just a sensation; it’s the mucilage working as intended.

Low-Fat or Plant-Based Milk

For many people, plant-based milks — particularly oat milk and almond milk — are well tolerated with acid reflux because they tend to have a neutral to slightly alkaline pH and don’t stimulate significant gastric acid production. Oat milk in particular has a mild, soothing effect on the gut and is a reasonable swap for regular dairy in morning drinks or cereal.

Regular cow’s milk is more variable. Some people find it temporarily soothing, but the fat content in full-fat milk can relax the LES and slow gastric emptying — potentially worsening reflux over the following hour or two despite the initial relief. If you use dairy milk, stick to skimmed or low-fat varieties.

Avoid coconut milk in large quantities — while low in acidity, it’s very high in fat and can slow gastric emptying significantly, increasing the window for reflux.

Ginger Tea

Ginger has documented anti-nausea and prokinetic properties — it can help support gastric emptying, which reduces the window during which food remains in the stomach and can reflux upward. For people whose reflux is worsened by slow gastric emptying (a common pattern in GERD), this can be genuinely useful. Ginger tea is non-acidic, non-caffeinated, and generally well tolerated.

The key is to avoid ginger tea products that use citric acid or added flavourings — check the ingredients. Plain ginger root steeped in hot water, or a clean ginger tea bag with no acidic additives, is what you want. I cover ginger in more detail in my article on ginger and acid reflux.

Drinks to Avoid With Acid Reflux

Coffee and Caffeinated Drinks

Coffee is one of the most consistently problematic drinks for reflux, and the mechanism is important to understand. People often assume coffee is a problem purely because of its acidity. But the evidence shows that coffee reduces LES pressure regardless of its pH — meaning even pH-neutral coffee causes the valve above your stomach to weaken. A study measuring LES pressure after coffee consumption found that both acidic (pH 4.5) and pH-neutral coffee produced significant reductions in LES pressure in healthy volunteers, and the effect was even more pronounced in patients with reflux esophagitis [Babka & Castell, Gastroenterology, 1980].

Additionally, both regular coffee and decaffeinated coffee stimulate gastric acid secretion to a comparable degree — suggesting that compounds other than caffeine in coffee (such as certain acids and oils) are responsible for driving acid production [Cohen & Booth, New England Journal of Medicine, 1975]. This is why low-acid or “stomach-friendly” coffee products offer limited real-world benefit for most reflux sufferers.

During active healing, I’d recommend avoiding coffee entirely. Once symptoms have settled and you’re in a maintenance phase, some people tolerate one small cup of a lighter roast early in the day — but it should be treated as a trial, not an assumption.

Alcohol

Alcohol is problematic for reflux through multiple mechanisms simultaneously. It reduces LES pressure (making reflux easier), stimulates gastric acid secretion, delays gastric emptying, and directly damages the esophageal mucosa — making it more vulnerable to acid injury. Research has confirmed that regardless of the type and dose of alcoholic beverage, alcohol facilitates the development of GERD by reducing LES pressure and impairing esophageal motility, while fermented drinks specifically also increase gastric acid production [Bujanda, Journal of Clinical Gastroenterology, 2000].

A separate study found that even short esophageal exposure to ethanol makes the mucosa significantly more vulnerable to acid damage — and this vulnerability persists for at least an hour after the alcohol has cleared, meaning a drink before a meal can set up your esophagus to be more easily damaged by the meal itself [Salo & Kivilaakso, Gastroenterology, 1999].

Some people ask about lower-acid alcohol options like potato-based vodka or gin. While these are less acidic than wine or beer, the LES-relaxing effect of the ethanol itself remains, which means they still increase reflux risk — just without the additional acidity burden. During active recovery from LPR or significant GERD, I recommend avoiding alcohol entirely. After symptoms have stabilised, any alcohol reintroduction should be cautious and rare.

Carbonated Drinks (Including Sparkling Water)

The gas in carbonated beverages causes gastric distension — essentially over-inflating the stomach — which triggers transient LES relaxations and significantly increases reflux risk. A study measuring LES pressure after consumption of various carbonated beverages found that all carbonated drinks produced a sustained 30–50% reduction in LES pressure lasting 20 minutes, and in 62% of subjects the reduction was enough to bring sphincter pressure to levels normally diagnostic of incompetence [Shay et al., Digestive Diseases and Sciences, 2006].

This is important for LPR in particular. The forceful belching that carbonated drinks produce is itself a mechanism for reflux reaching the throat. Even sparkling mineral water with a higher pH is still carbonated, and the gas effect on LES pressure outweighs any benefit from the pH. Stick to still water.

Soda is doubly problematic — it combines the LES-relaxing effect of carbonation with a very low pH (most colas are pH 2.5–3.5), which means it both promotes reflux and, for anyone with LPR, aggressively reactivates any pepsin in the throat the moment it makes contact.

Fruit Juice and Citrus Drinks

Orange juice, grapefruit juice, lemon water, and most commercial fruit juices are highly acidic — typically pH 3–4. For someone with LPR, drinking these is one of the fastest ways to reactivate dormant throat pepsin. Even juices that seem “healthy” — like pomegranate juice or cranberry juice — tend to be very acidic and should be avoided during active symptom management.

If you want a fruit-based drink, diluting a small amount of lower-acid juice (such as pear or melon juice) with a large amount of water is a safer approach than drinking full-strength juice, and even then it’s best kept occasional rather than daily.

Regular Tea (Caffeinated)

Caffeinated tea — black, green, and most commercial teas — has a similar LES-relaxing effect to coffee. A blinded crossover study found that both regular coffee and regular tea significantly reduced LES pressure compared to water, while decaffeinated coffee did not produce the same effect, confirming that caffeine (rather than other tea compounds) is the main driver of reflux risk in standard teas [Thomas et al., Digestive Diseases and Sciences, 2010].

Peppermint tea deserves a specific mention even though it’s caffeine-free — it relaxes smooth muscle throughout the gastrointestinal tract including the LES, and frequent peppermint tea consumption has been associated with a two-fold increased risk of GERD symptoms. It should be avoided if you have reflux, despite being commonly marketed as a “digestive” tea.

Energy Drinks

Energy drinks combine multiple reflux triggers in one can: high caffeine content, acidic pH (typically 3–4), carbonation, and often added citric acid. They’re among the worst possible choices for anyone with GERD or LPR and should be avoided entirely during symptom management.

Practical Drinking Habits That Help

Beyond choosing the right drinks, how and when you drink also matters for reflux.

Drinking large amounts of any liquid with meals can increase gastric volume and pressure, promoting reflux — particularly in the immediate post-meal period. Sipping water throughout a meal is fine, but avoiding large glasses of liquid right at the end of a meal can help. Similarly, stopping liquids (other than a small amount of water) at least 30 minutes before lying down reduces the amount of content available to reflux during sleep.

Drinking a small amount of alkaline water after meals — particularly after anything that may have contained some acidity — helps wash residual food acids out of the throat and esophagus while potentially inactivating any pepsin that arrived via reflux during the meal.

The overall drinking pattern matters too. A diet heavy in coffee, juice, and alcohol provides a near-constant stream of pepsin-reactivating stimuli throughout the day, making it essentially impossible for LPR throat damage to heal even if you’re doing everything else right. Shifting your drink choices as a whole — not just cutting one item — tends to produce the most meaningful improvement. For a complete framework that covers both drink and food choices, the Wipeout Diet Plan maps this out in practical, structured detail.

Conclusion

The best drinks for acid reflux are alkaline water (pH 8.8+), plain still water, chamomile tea, marshmallow root tea, and ginger tea. The drinks to avoid are coffee, alcohol, all carbonated drinks, fruit juice, and regular caffeinated tea — not just because they’re acidic, but because most of them also weaken the LES, increase acid production, or directly reactivate the pepsin that’s driving throat and esophageal damage.

Getting your drink choices right is one of the highest-leverage changes you can make for reflux, particularly for LPR where the throat is the target of pepsin-mediated damage. It doesn’t require giving up everything enjoyable forever — but during active recovery especially, the drinks you choose daily have a direct and measurable effect on how quickly (or slowly) your symptoms improve.

If you want to combine the right drink choices with a full dietary and lifestyle approach to reflux recovery, the Wipeout Diet Plan is built around the same pepsin and LES mechanisms described in this article — giving you a structured, practical framework for getting symptoms under control for the long term. And if you’d like personalised guidance on your specific situation, I also offer one-to-one consultations.

Frequently Asked Questions

What is the best drink for acid reflux?

Alkaline water at pH 8.8 or above is the best drink specifically for LPR and reflux, because research has shown it irreversibly inactivates pepsin and has strong acid-buffering capacity. For everyday hydration where alkaline water isn’t available, plain still water is the safest and most reliable choice. Chamomile tea is the best warm drink option, being non-acidic with anti-inflammatory properties that support the digestive tract.

Can I drink coffee if I have acid reflux?

Coffee consistently reduces LES pressure regardless of its pH, which is why it triggers reflux even at neutral pH levels. Both caffeinated and decaffeinated coffee also stimulate gastric acid secretion. During active recovery from LPR or significant GERD, I’d recommend avoiding it entirely. Once symptoms have fully settled, some people can tolerate a small amount — but it should be treated as a cautious trial rather than a resumption of normal habit.

Is sparkling water okay for acid reflux?

No — even alkaline sparkling water should be avoided. The carbonation itself causes gastric distension which triggers LES relaxation and reflux, and carbonated drinks have been shown to reduce LES pressure by 30–50% for up to 20 minutes after consumption. The gas that enters the stomach is the problem, not just the pH of the water. Always choose still water over sparkling.

What herbal teas are safe for acid reflux?

Chamomile, marshmallow root, and ginger teas are the best options. Chamomile is anti-inflammatory and soothing; marshmallow root forms a protective mucilaginous coating on the throat and esophageal lining; and ginger has prokinetic properties that support gastric emptying. Avoid peppermint tea — despite its reputation as a “digestive” tea, it relaxes the LES and significantly increases GERD symptom risk.

Is milk good for acid reflux?

Skimmed or low-fat plant-based milks — particularly oat milk and almond milk — are generally well tolerated with reflux due to their neutral to slightly alkaline pH and low fat content. Full-fat dairy milk can temporarily feel soothing but may worsen reflux in the following hour or two due to its fat content relaxing the LES and slowing gastric emptying. If you use milk, low-fat or plant-based varieties are preferable.

Is alcohol ever okay with acid reflux?

During active recovery from LPR or significant GERD, I’d recommend avoiding alcohol entirely. It reduces LES pressure, stimulates acid secretion, delays gastric emptying, and directly damages the esophageal mucosa — all at once. Once symptoms have fully resolved and you’re in a stable maintenance phase, some people can tolerate occasional moderate alcohol. Less acidic options like gin or a good vodka with still water are lower-risk than wine or beer, but the LES-relaxing effect of the ethanol itself remains regardless of what you drink.

What can I drink in the morning with acid reflux?

Start with a glass of still water or alkaline water before anything else — this helps clear the throat and esophagus of any overnight reflux. Follow with chamomile tea, ginger tea, or oat milk if you want something warm. Avoid coffee and fruit juice in the morning, which are two of the most common morning triggers. If you need something hot with caffeine, some people tolerate small amounts of low-acid, light-roast coffee after symptoms have settled — but this should be a later experiment, not an immediate first step.

Alkaline water at pH 8.8 irreversibly inactivated human pepsin in vitro and demonstrated acid-buffering capacity far exceeding conventional drinking water, supporting its use as a therapeutic adjunct for reflux [Koufman & Johnston, The Annals of Otology, Rhinology & Laryngology, 2012]. In a prospective study of 48,308 women, replacing 2 daily servings of coffee, tea, or soda with water was associated with significantly reduced GERD symptom risk [Mehta et al., Clinical Gastroenterology and Hepatology, 2020].

Caffeinated coffee at both acidic and neutral pH reduced LES pressure significantly in healthy volunteers and reflux patients, confirming its refluxogenic effect is independent of its acidity [Babka & Castell, Gastroenterology, 1980]. Both regular and decaffeinated coffee stimulated gastric acid secretion to a similar degree, suggesting non-caffeine compounds drive coffee’s acid-promoting effects [Cohen & Booth, New England Journal of Medicine, 1975].

Regular caffeinated coffee and tea both significantly reduced LES pressure compared to water and decaffeinated coffee in a blinded crossover study, with caffeine identified as the primary driver [Thomas et al., Digestive Diseases and Sciences, 2010]. Alcohol reduces LES pressure and esophageal motility regardless of beverage type and dose, while fermented beverages additionally stimulate gastric acid secretion [Bujanda, Journal of Clinical Gastroenterology, 2000].

Ethanol directly damages esophageal epithelium and substantially increases its vulnerability to acid injury for at least 1 hour after alcohol clearance [Salo & Kivilaakso, Gastroenterology, 1999]. All carbonated beverages tested produced a sustained 30–50% reduction in LES pressure lasting 20 minutes, with 62% of subjects reaching sphincter pressures diagnostic of incompetence [Shay et al., Digestive Diseases and Sciences, 2006].
