The pH of Apple Cider Vinegar vs Lemon Juice: A Comprehensive Comparison

The pH value of apple cider vinegar typically ranges between 2-3, while lemon juice has a pH closer to 2, making it slightly more acidic. Both substances become alkaline when metabolized in the body, meaning they do not affect the body’s natural pH. This article will delve into the nuances of the pH levels, nutrient profiles, and potential effects of these two popular health-conscious ingredients.

Understanding the pH Levels

The pH scale measures the acidity or basicity of a substance, with a range from 0 to 14. A pH value of 7 is considered neutral, while values below 7 are acidic, and values above 7 are basic or alkaline.

Substance pH Range
Apple Cider Vinegar 2-3
Lemon Juice ~2

As the table shows, apple cider vinegar and lemon juice are both highly acidic, with lemon juice being slightly more so. However, it’s important to note that the pH of these substances can vary depending on factors such as the specific brand, production methods, and even the ripeness of the fruit.

Nutrient Profiles

While both apple cider vinegar and lemon juice offer health benefits, they differ in their nutrient compositions.

Lemon Juice

Lemons are rich in vitamin C, antioxidants, and citric acid. These nutrients may support skin health, immune function, and digestion.

Apple Cider Vinegar

Apple cider vinegar contains acetic acid, which has been associated with weight management and blood sugar control. The best brands of apple cider vinegar also include the “mother,” a collection of enzymes and beneficial bacteria.

Taste and Consumption

In terms of taste, lemon water is zesty and refreshing, with a delightful citrus punch, while apple cider vinegar has a tangy, sour flavor that can be quite intense on its own.

It’s essential to dilute both apple cider vinegar and lemon juice before consuming them, as they can cause digestive discomfort if not diluted. For apple cider vinegar, a common recommendation is to mix 1-2 tablespoons with a glass of water. For lemon juice, squeeze the juice of half a lemon into a glass of warm or room-temperature water.

Effects on Fermentation and Tooth Enamel

When comparing the effects of lemon juice and apple cider vinegar on Saccharomyces cerevisiae fermentation, a study found that apple cider vinegar had a more significant effect on ethanol production than lemon juice.

Regarding potential contaminants, a study examining the erosive effects of acidic beverages and dietary preservatives on extracted teeth found that vinegar showed the maximum weight change post-exposure, while apple cider and lemon juice induced maximum changes in striae of Retzius and dentinal tubules. This suggests that apple cider and lemon juice may have similar effects on tooth enamel.


In conclusion, both apple cider vinegar and lemon juice have their unique benefits and drawbacks. Lemon juice is high in vitamin C and antioxidants, while apple cider vinegar contains acetic acid and beneficial bacteria. Both should be diluted before consumption and may have similar effects on tooth enamel. When choosing between the two, consider your personal preferences and specific health goals.
