How much lemon juice do you get from one lemon?

In this article, we will briefly discuss a commonly asked question, ‘how much lemon juice do you get from one lemon?’ and discuss what determines how much juice is in one lemon as well as the benefits and risks of drinking lemon juice.

How much lemon juice do you get from one lemon?

A study showed that the lemon yields on average 43.8% juice. That is lower than orange (45.2%) and mandarin (51.8%) (1). Another study reported a juice yield of 41.6% and 44.3% for two different Spanish lemon varieties (8).

A lemon weighs in everage 5 ounces (140 g), but varies between 3.5 and 6.3 ounces (100 – 178 g), according to studies. 

In this way, it is possible to obtain 1.5 ounces of lemon juice from a small lemon and 2.7 ounces of lemon juice from a big lemon. On average, you can get 2.15 ounces of lemon juice from a middle-sized lemon.

What determines how much lemon juice you get from one lemon?

The factors that determine how much juice you can get from a lemon are (1,6,8):

  • The lemon variety: different lemon cultivars yield different amounts of juice. The yield depends on the fertilization, irrigation, soil and other environmental factors, that also influences the chemical composition of the lemon and its juice
  • The extraction method: if the juice is hand pressed or extracted by an equipment can determine how much lemon juice you can get from the lemon. A study showed that the highest yield of lemon juice was obtained by screw-press extractor
  • The harvest time: when fruits are harvested in their optimal season, a higher amount of juice can be obtained. Similarly, when the lemons are riper, their skin and tissues are softer and can be pressed easier and yield a higher amount of juice
  • A study reported that fruits with a thinner skin contain greater amounts of juice than fruits with a thicker skin

What are the benefits of consuming lemon juice?

Lemon provides the following health benefits. The main benefits of consuming lemon juice are following:

Immunity booster

Lemon juice contains vitamin C, which is an antioxidant and is able to neutralize reactive oxygen species which cause oxidative stress. Vitamin C improves the immune system by supporting the activities of the leukocytes and lymphocytes (2). The supplementation of vitamin C during infections can reduce the time needed for recovery and restoration of health.

Heart health

The vitamin C in lemon juice can be related to better heart health. The hypothesis that supports the observational studies showing that the intake of vitamin C can reduce the risks of heart disease is based on the hypotensive effect of the ingestion of vitamin C. Supplementation of vitamin C or the intake through diet can reduce blood pressure and consequently improve heart health (3).

Kidney stones

Citrus juices are related to disrupting stone formation in the body. The concentrated urine can lead to the formation of kidney stones, as there is crystallization of salts in the urine. Citrus fruits increase the levels of citrates in the urine, resulting in the lower crystallization of uric acids and therefore lower stone formation (4).

Prevent anemia

Citrus fruits are rich in folic acid which is required for the formation of red blood cells. The lack of folic acid can lead to anemia. The sufficient ingestion of folic from citrus is also recommended to pregnants, as folic acid can reduce neural tube defects in the fetus (4). 

Cancer prevention

The many polyphenols in lemon juice are related to a reduced risk of many types of cancer. Terpenoids, flavonoids and other compounds are reported to inhibit the proliferation of tumor cells in liver and breast cancers (4).

What are the risks of consuming lemon juice?

The risks of consuming lemon juice are related to allergic reactions to the flavonoids present in the fruit, which can trigger slight to moderate histaminic reactions to sensitive individuals (4).

Also, citric acid from lemon juice is reported to wear down the enamel of your tooth causing sensitivity and is a risk factor for the higher erosion of the teeth. The increased consumption of acidic beverages, including lemon juice, is related to higher incidence of dental erosion (5).
