How Does Lemon Juice Neutralize Stomach Acid

Lemon juice is known for its acidic nature, yet it surprisingly has an alkalizing effect on the body when consumed. This is due to its rich content of citric acid, which gets metabolized and leaves behind alkaline byproducts upon digestion. When stomach acid levels rise, lemon juice can help neutralize the excess acidity by stimulating the production of bicarbonate ions in the stomach.

Bicarbonate ions act as a buffer, reducing the overall acidity and maintaining a proper pH balance. In this way, lemon juice can combat the discomfort caused by excessive stomach acid and promote a healthier digestive system.


To neutralize stomach acid with lemon juice, follow these steps in detail:

1. Choose a fresh lemon:
Select a ripe lemon that feels heavy and has a bright yellow color. Avoid using bottled lemon juice as it may contain additives or preservatives.

2. Squeeze the juice:
Cut the lemon in half and use a citrus juicer or simply squeeze it by hand to extract the juice. Ensure you remove any seeds or pulp.

3. Dilute the lemon juice:
Pour the lemon juice into a glass of water. The ratio of lemon juice to water can vary depending on personal preference. A common ratio is 1 tablespoon of lemon juice to 8 ounces of water. Start with a smaller amount if you are new to using lemon juice for this purpose.

4. Stir well:
Mix the lemon juice and water together using a spoon. Stir until the lemon juice is fully blended with the water.

5. Drink after a meal:
It is recommended to consume lemon juice after eating a meal to help neutralize stomach acid effectively. Drinking it on an empty stomach may cause discomfort for some individuals.

6. Observe the effects:
Pay attention to your body’s response to the lemon juice. Some people may find relief from acid reflux or heartburn symptoms shortly after consuming it, while others may need to repeat the process several times for noticeable results.

7. Adjust as needed:
If you find that a smaller amount of lemon juice is not effective, you can gradually increase the ratio of lemon juice to water, or consult with a healthcare professional for personalized advice. Remember to consult with a healthcare professional if you experience chronic or severe acid reflux symptoms as they may require further medical intervention.

Frequently Asked Questions:

What is the science behind how lemon juice neutralizes stomach acid?

Lemon juice contains citric acid, a weak acid. When consumed, it combines with stomach acid (hydrochloric acid) due to a chemical reaction, forming a neutral substance. This reaction helps in neutralizing excess stomach acid, which may provide relief for individuals experiencing heartburn or acid reflux.

How does the acidic nature of lemon juice help balance the pH levels in the stomach?

The acidic nature of lemon juice helps balance the pH levels in the stomach by stimulating the production of stomach acids. This increased production can help neutralize excess alkalinity in the stomach, promoting proper digestion and preventing issues such as heartburn and indigestion.

Are there any potential risks or side effects of using lemon juice to neutralize stomach acid?

Potential risks or side effects of using lemon juice to neutralize stomach acid include tooth enamel erosion due to its acidic nature, increased risk of acid reflux or heartburn, and worsening of gastritis or stomach ulcers. It’s important to consult a healthcare professional before using any home remedies to treat stomach acid or related conditions.

Can consuming lemon juice provide long-term relief from acid reflux or heartburn symptoms?

Lemon juice may provide temporary relief from acid reflux symptoms due to its alkaline nature, but its long-term effects are unclear. While it can help neutralize stomach acid, excessive consumption may worsen symptoms for some individuals. Consulting a healthcare professional is advised for proper diagnosis and treatment.


In conclusion, lemon juice neutralizes stomach acid due to its high acidity. When consumed, lemon juice stimulates the production of bicarbonate ions in the stomach, which helps to counteract and balance the acidity. Its acidic properties work to reduce the overall pH level, relieving symptoms of heartburn and acid reflux.
