What is the pH of Lemon Juice?

Many people wonder about the pH of lemon juice, particularly if they have problems with acidity in their gastrointestinal system. While lemon is quite acidic, it behaves in some very interesting ways within the body.

What is the ph of Lemon Juice?

The pH value of lemon juice is 2.0, making this juice extremely acidic. On the pH scale, anything below 7 is considered an acid, while anything above 7 is considered a base – an alkaline substance. Something with a similar acidity level is vinegar, while apples are slightly less acidic, and sulfuric acid is more acidic. Although this might make most people think that drinking lemon juice will create an acidic setting in your body, there is more to the story than that.

What Are the Acids Present in Lemon Juice?

There are a number of acids present in lemon juice that provide such an acidic characteristic, including citric acid, ascorbic acid, and malic acid.

Citric Acid

Lemons have more citric acid by weight than any other citrus fruit – roughly 8% of their dry weight, in fact. This citric acid is not known for having many effects on the body, but it does have protective effects on the fruit itself, helping to prevent browning and maintaining the sharp, citrusy bite in this fruit juice.

Ascorbic Acid

Ascorbic acid is better known by its common name, vitamin C. The juice from a single lemon would provide roughly 30% of your recommended daily intake of that nutrient, which can act as a major boost to your immune system since vitamin C stimulates the production of white blood cells. Ascorbic acid is also an integral part of the creation of bodily tissues and collagen, which is required for all the repair and growth processes in the body.

Malic Acid

Found in the smallest amount of lemon juice, malic acid is not a well-known acid for human health, although research has found it to help people with certain muscle disorders. Patients who are unable to produce malic acid in their body can benefit from lemon juice, which helps to reduce inflammation and pain in their soft muscle tissue.

Lemon Juice and the ph of Your Body

As mentioned, the low pH of lemon juice leads many to believe that it will have an acidic effect on the body, but that simply isn’t the case. Based on how the body metabolized lemon juice and its active components, drinking this juice actually has an alkalizing effect on the body. That being said, the body works very hard to maintain an even pH of between 7.35 and 7.45, and there is little that you can do to affect that.

Lemon juice is known to increase the acidity of the urine because the body expels excess acid through the urine. The alkalizing effect will happen in the blood. In terms of measurable effects on the body, lemon juice may have a slightly alkalizing effect, which can help to settle stomach disorders and other symptoms of excess acidity.
