Is lemonade OK to drink with acid reflux?

Acid reflux is a common condition that many people experience occasionally after eating certain trigger foods. The most characteristic symptom is a burning sensation in the chest or throat known as heartburn. Lemonade is a beverage made from lemon juice, water, and sweetener that some people find aggravating for acid reflux symptoms while others can tolerate it without problems. This article will explore whether or not lemonade is OK to drink if you have acid reflux.

What is acid reflux?

Acid reflux occurs when stomach acid flows back up into the esophagus, causing irritation of the esophageal lining. The esophagus is the tube connecting the throat to the stomach. A ring of muscle known as the lower esophageal sphincter normally acts as a barrier to keep stomach contents from coming back up. When this muscle becomes weakened or relaxed, acid can reflux into the esophagus, producing heartburn and other symptoms.

Some common signs and symptoms of acid reflux include:

  • Heartburn – a burning discomfort usually in the center of the chest that sometimes spreads to the throat
  • Regurgitation – the sensation of acid backing up into the throat or mouth
  • Bitter or sour taste in the mouth
  • Excessive burping
  • Chronic sore throat
  • Laryngitis
  • Chronic cough
  • Asthma symptoms
  • Difficulty swallowing

Acid reflux occurs when the lower esophageal sphincter becomes weakened or damaged, allowing stomach acid to flow back into the esophagus. Certain foods, beverages, medications, being overweight and pregnancy can all contribute to a weak esophageal sphincter and acid reflux symptoms. Even physical activity right after eating can promote reflux.

What is in lemonade that matters for acid reflux?

The main ingredients in basic lemonade are lemon juice, water and a sweetener such as sugar or honey. The key component that makes lemonade potentially problematic for acid reflux is the lemon juice. Lemons contain high amounts of citric acid and ascorbic acid, both of which promote acidity and can irritate the esophageal lining.

Here is the acidic profile of one 8 ounce serving of lemon juice:

  • pH: 2.2-2.4 (very acidic)
  • Citric acid: 5-9%
  • Ascorbic acid: 50-60 mg
  • Tartaric acid: 2.4 mg

This acidic profile explains why straight lemon juice can trigger acid reflux symptoms. The citric and ascorbic acids are the main compounds that give lemon juice its sour flavor and low pH.

However, when diluted in water and sweetened with sugar or honey, lemonade has a much less acidic pH that many find more tolerable.

Does lemonade make acid reflux worse?

Whether lemonade exacerbates acid reflux symptoms depends on the individual. Here are some factors to consider:

  • Acidity – The more diluted the lemon juice is, the less acidic the lemonade. A very concentrated, sour lemonade would likely worsen symptoms.
  • Quantity – Drinking a small 4-8oz glass with a meal may be tolerable, while drinking large amounts can increase risk.
  • Other ingredients – Added citrus fruits or juices besides lemon would increase the acid load.
  • Sweetener – The type of sweetener may also play a role. Honey may be more soothing than regular sugar.
  • Timing – Drinking lemonade outside of mealtimes may cause less reflux than drinking it with food.
  • Individual tolerance – Due to differences in triggers and symptom severity, lemonade may bother some people with reflux but not others.

Those with more mild reflux can typically handle diluted lemonade in moderation with no problems. However, people with frequent or severe reflux symptoms may find even small amounts bothersome.

Reasons lemonade could improve reflux

Despite its acidic pH, there are some ways in which lemonade might actually help improve acid reflux in certain cases:

  • Promotes saliva – The tart citrus taste can stimulate saliva production, which helps neutralize acid.
  • Aids digestion – Lemon juice contains citric acid, a mild natural acid that may help support digestion.
  • Calms nausea – The cool, sweet flavor can settle nausea, which is common with reflux.
  • Provides hydration – Staying hydrated is important for controlling acid reflux.

There is some evidence that lemon water may also provide benefits by stimulating movement in the esophagus and stomach, potentially helping clear acid. However, more research is needed.

Tips for drinking lemonade with acid reflux

Here are some tips to follow if you want to drink lemonade but need to minimize acid reflux symptoms:

  • Always dilute lemon juice well in water – use just a tablespoon or two per glass.
  • Moderate your portion sizes – stick to 4-8oz per serving.
  • Avoid adding extra citrus juices or slices.
  • Sweeten with honey rather than regular sugar if possible.
  • Drink lemonade between rather than during meals.
  • Wait at least 2-3 hours after meals before drinking it.
  • Avoid drinking lemonade before bedtime.
  • Sip slowly and avoid gulping it down.
  • Pay attention to your symptoms and avoid lemonade if it consistently worsens reflux.

What drinks are safer alternatives?

For those who find that even diluted lemonade aggravates their reflux, here are some lower acid options to consider instead:

  • Water – plain or infused with fruits/herbs
  • Almond milk or oat milk
  • Chamomile or ginger tea
  • Decaf green tea
  • Low acid fruit juices like apple or aloe vera
  • Vegetable juices like carrot, celery or cucumber
  • Smoothies made with non-citrus fruits and yogurt or milk

Carbonated beverages like soda should be avoided as the bubbles can promote reflux. Coffee, orange juice, and other high acid juices will likely worsen symptoms as well.

The effect of lemonade ingredients on acid reflux

Let’s take a more in-depth look at how the different ingredients in lemonade can impact acid reflux:

Lemon juice

Lemon juice is acidic with a pH around 2-3. The main acids are citric and ascorbic acid. The high acid content can irritate the esophagus. However, when diluted, its effect is diminished. Start with just 1-2 tablespoons lemon juice per 8oz glass.


Water helps dilute the acidity of the lemon juice. Adequate water also helps prevent dehydration, which can worsen reflux. Avoid carbonated water as the bubbles can promote reflux.


Regular table sugar does not directly affect acid reflux. However, excess intake can lead to obesity, a risk factor for reflux. Honey may be a better choice as it can coat and soothe the throat.


Drinking icy cold lemonade can be helpful as the cool temperature helps numb irritation in the esophagus. Don’t chew the ice as it could damage teeth. Sucking on ice chips can also provide relief.

Mint leaves

Mint is sometimes added to lemonade for flavor. Peppermint oil has been shown to relax the lower esophageal sphincter and make reflux worse, so avoid adding mint.

Ingredient Impact on Acid Reflux
Lemon juice Can aggravate if concentrated; dilute well
Water Helps dilute acidity; improves hydration
Sugar No direct impact; honey may be soothing
Ice Can numb irritation; don’t chew ice
Mint leaves Can relax esophageal sphincter; avoid


In conclusion, drinking lemonade can be tolerated by some people with acid reflux, as long as servings are kept small and it is sufficiently diluted with water. It is wise to pay attention to your personal tolerance level. Those with more frequent or severe reflux will likely need to avoid lemonade. For the best results, drink lemonade between rather than during meals and limit other acidic foods at mealtimes. Always dilute the lemon juice well, avoid large amounts, and drink slowly. If lemonade consistently makes your symptoms worse, choose safer, lower acid beverages instead.
