Which juice has no acid?

Juice is a popular beverage choice for many people looking for a refreshing and nutritious drink. While most juices contain beneficial vitamins and minerals, some may also have high acid content. For those with reflux or acid sensitivity, knowing which juices are low acid or acid-free can help guide healthier choices.

What Causes Acidity in Juice?

The acidity of juice is primarily determined by its ingredients and preparation method. Citrus fruits like oranges, grapefruits, lemons, and limes contain high amounts of citric acid, malic acid, and ascorbic acid (vitamin C) which impart a tart, sour taste. Apple, grape, and cranberry juices also have moderately high acid levels. Fermented juices like apple cider vinegar contain acetic acid from the fermentation process.

Acids are also produced when juice sits out and oxidizes or is processed and bottled. Extended storage times, exposure to air, higher temperatures, copper and iron levels, and other factors can cause juices to lose base minerals over time and become more acidic.

Health Impacts of High Acid Juices

While acids naturally occur in fruits and vegetables, excessive consumption, especially on an empty stomach, may trigger reflux symptoms like heartburn, indigestion, and irritation of the esophagus. Highly acidic juices can also erode tooth enamel over time when sipped frequently. For those with chronic acid reflux or GERD, acidic juices may aggravate the lower esophageal sphincter, allowing stomach contents to leak up into the esophagus.

However, not all acids have the same effect. Citric and malic acid in moderation are generally fine for most people. Some acidic juices like apple cider vinegar are also touted for health benefits when diluted with water. But for those sensitive to acids, lowering dietary acid intake from drinks can provide relief.

Choosing Low Acid Juices

So which juices tend to be less acidic? Here are some better options if watching your acid intake:

  • Coconut water – Neutral pH
  • Aloe vera juice – Alkaline pH
  • Cucumber juice – Neutral pH
  • Watermelon juice – Neutral pH
  • Honeydew melon juice – Neutral pH
  • Banana juice – Mildly acidic
  • Papaya juice – Mildly acidic
  • Mango juice – Mildly acidic
  • Blueberry juice – Mildly acidic
  • Pomegranate juice – Mildly acidic

While melons, bananas, papaya, and other fruits have lower acidity, their juice may be difficult to find commercially. Making your own fresh juices at home gives you control over the ingredients.

Tips for Reducing Acidity of Juice

There are also simple tricks to reduce the acidity of homemade or store-bought juice:

  • Dilute with water – Add ice and/or still or sparkling water.
  • Mix with non-acidic juice – Combine with aloe, coconut water, cucumber, etc.
  • Balance acidity – Add a squeeze of lemon to mellow acidity of fruits like pineapple or grapefruit.
  • Consume with meals – Drink with food to minimize acid effects on an empty stomach.
  • Limit serving size – Drink 4-8 oz per serving and avoid large amounts.
  • Avoid sugar – Added sugars increase acidity and fermentation.
  • Control storage time – Refrigerate after opening and finish within a few days.

The Least Acidic Fruit and Vegetable Juices

Looking specifically at produce, here is a table comparing the pH of common fruit and vegetable juices from lowest acidity to highest:

Juice pH Level
Coconut water 7.4 (neutral)
Aloe vera juice 7.0 (neutral)
Cucumber juice 6.7 (neutral)
Watermelon juice 6.2 (neutral)
Honeydew juice 6.1 (neutral)
Banana juice 5.6 (mildly acidic)
Papaya juice 5.2 (mildly acidic)
Mango juice 4.9 (mildly acidic)
Blueberry juice 4.5 (mildly acidic)
Pomegranate juice 3.6 (mildly acidic)
Pineapple juice 3.5 (mildly acidic)
Orange juice 3.3 (moderately acidic)
Grape juice 3.2 (moderately acidic)
Apple juice 3.1 (moderately acidic)
Tomato juice 4.1 (moderately acidic)
Cranberry juice 2.5 (highly acidic)
Grapefruit juice 2.5 (highly acidic)
Lemon juice 2.0 (highly acidic)
Lime juice 2.0 (highly acidic)

As shown, coconut water, aloe vera, cucumber, watermelon, and honeydew juices are the least acidic options with neutral pH levels around 7. Papaya, mango, banana, blueberry, and pomegranate juices are mildly acidic choices. Pineapple, orange, grape, apple, and tomato juices have moderate acidity, while cranberry, grapefruit, lemon, and lime juices are very highly acidic with pH less than 3.

Benefits of Non-Acidic Fruit Juices

Choosing low acid juices still provides key nutrients and health benefits. Here are some of the positives of juices with neutral pH levels:

  • Coconut Water – Rich in electrolytes like potassium and magnesium for hydration.
  • Aloe Vera Juice – Contains antioxidants, vitamins, and enzymes that support digestion.
  • Cucumber Juice – High water content keeps the body hydrated.
  • Watermelon Juice – Packed with amino acids, electrolytes, and antioxidants like lycopene.
  • Honeydew Juice – Good source of vitamin C, potassium, folate, and vitamin B6.

Even mildly acidic juices like banana, papaya, mango, and pomegranate provide antioxidants, minerals like potassium, and unique compounds like papain and lycopene with health and anti-inflammatory benefits.

Choosing the Best Juices for You

Those with reflux, GERD, sensitive stomachs, or ulcer issues may benefit from limiting acidic juices. But the optimal juice choices really depend on your nutritional needs and tolerance. Here are some tips:

  • Monitor symptoms and avoid juices that trigger discomfort.
  • Dilute or limit serving sizes of acidic juices instead of avoiding them completely.
  • Get nutrients like vitamin C from less acidic whole fruits and veggies too.
  • Consider mixing alkaline aloe or coconut water with acidic juices to help neutralize them.
  • Rinse mouth with plain water after consuming acidic juices to protect teeth.
  • Look for low-sugar, pulp-free, or freshly made juices for less oxidation.
  • Focus on getting a rainbow of different fruit and vegetable juices for balanced nutrition.

While acidic juices can be fine for most in moderation, being mindful of pH and how different juices affect you individually can help guide healthier and more comfortable choices.


Finding low acid juices is made easier by knowing which fruits and vegetables are naturally less acidic. Coconut water, aloe, cucumber, watermelon, and honeydew juices have a neutral pH and are least likely to cause discomfort. Mildly acidic options like banana, mango, and pomegranate can provide nutrients while limiting acid intake. Diluting, limiting serving sizes, and drinking alongside meals can further reduce the acid impact of juice. Consider your own tolerance levels and aim for balance and variety when incorporating juice into a healthy diet.
