What kind of juice is a diuretic?

Juice can be an excellent way to get nutrients and stay hydrated. However, some juices may have diuretic effects, meaning they can make you urinate more frequently. Certain fruits and vegetables contain compounds that may stimulate urine production.

What is a diuretic?

A diuretic is any substance that increases the production of urine. Diuretics help the body get rid of excess fluid and salt through urination. There are several types of diuretics:

  • Osmotic diuretics – These draw water from the blood into the urine, increasing urine volume. Examples include glucose, mannitol and glycerol.
  • Loop diuretics – These work on the kidneys to prevent the reabsorption of sodium, leading to increased urine output. Furosemide is a common loop diuretic.
  • Thiazide diuretics – These block the kidneys from reabsorbing sodium and chloride, causing more urine production. Hydrochlorothiazide is a thiazide diuretic.
  • Potassium-sparing diuretics – These block sodium reabsorption without causing potassium loss. Spironolactone is a potassium-sparing diuretic.

Certain foods and drinks can have mild diuretic effects similar to osmotic diuretics. They contain compounds that pull fluid into the urine, potentially causing increased urination.

Fruits and vegetables with natural diuretic effects

Some fruits and vegetables have natural diuretic properties. Their high water and/or nutrient contents can increase urine output when consumed in large amounts. Fruits and veggies with potential diuretic effects include:

  • Watermelon: Very high water content at 92%
  • Cranberries: Contain organic acids that increase urine production
  • Lemon: Rich in citric acid, which has diuretic effects
  • Celery: Contains the compound apigenin, which acts as a mild diuretic
  • Lettuce: Has high water content and potassium, which can stimulate urination
  • Fennel: Acts as a diuretic due to compounds like anethole
  • Artichokes: Contains cynarin, which increases bile production and urine output
  • Asparagus: Amino acid asparagine may have mild diuretic effects
  • Onions: Sulfur compounds likely stimulate urination
  • Garlic: Contains allicin and other sulfur compounds that may increase urine production

Keep in mind that eating these fruits and veggies as part of a balanced diet is unlikely to cause major diuretic effects. But consuming large portions in excess may potentially stimulate urination.

Fruit and vegetable juices with diuretic effects

Drinking juices made from fruits and vegetables with natural diuretic properties may also have mild diuretic effects. Some examples include:

  • Cranberry juice: Full of organic acids that can increase urine output.
  • Lemon juice: High in citric acid, which helps stimulate urination.
  • Tomato juice: Contains potassium salts that act as osmotic diuretics.
  • Carrot juice: May have a mild diuretic effect due to mineral content.
  • Garlic juice: Contains sulfur compounds that can increase urine production.
  • Ginger juice: Gingerol may help with kidney filtration and urine output.
  • Onion juice: Sulfur compounds likely stimulate more frequent urination.
  • Celery juice: Apigenin gives it some diuretic activity.

Once again, drinking small-to-moderate amounts of these juices as part of a healthy diet is unlikely to cause major diuretic effects. Drinking large amounts may potentially stimulate increased urination.

Other drinks with diuretic effects

In addition to fruit and vegetable juices, other beverages can have a diuretic effect when consumed in excess. These include:

  • Coffee: Caffeine has a mild diuretic effect.
  • Tea: The caffeine and flavonoids in tea can stimulate kidney function and urine output.
  • Alcohol: Alcohol suppresses an antidiuretic hormone, leading to increased urine production.
  • Seltzer water: The carbonation causes a slight diuretic effect.

Again, having a small-to-moderate intake of these beverages is unlikely to significantly increase urination. But overdoing it, especially with alcohol and caffeine, can act as a diuretic.

Summary of juices and drinks with diuretic effects

Here is a summary of some of the main juices, fruits, vegetables and other drinks that may have a diuretic effect:

Beverage/Food Diuretic Compounds/Factors
Cranberry Juice Organic acids like quinic, malic, citric acids
Lemon Juice Citric acid
Celery Juice Apigenin
Carrot Juice Mineral content
Tomato Juice Potassium salts
Coffee Caffeine
Tea Caffeine, flavonoids
Alcohol Inhibits antidiuretic hormone
Seltzer Water Carbonation
Watermelon High water content
Celery Apigenin
Cranberries Organic acids
Lemon Citric acid
Asparagus Asparagine
Fennel Anethole
Onions Sulfur compounds
Garlic Allicin, sulfur compounds

Should you drink diuretic juices?

There are a few reasons you may want to drink juices with diuretic properties:

  • Reducing fluid retention and bloating: Diuretics can help flush excess water and salt from the body to relieve temporary fluid retention.
  • Lowering blood pressure: Increased urination can lower blood pressure by reducing fluid volume in the blood.
  • Supporting kidney function: Staying hydrated with fluids that stimulate urination can help flush the kidneys.
  • Aiding weight loss: Some people use diuretics to try to temporarily lose excess water weight, although this is not a permanent weight loss solution.

However, there are also some downsides to frequent urination caused by diuretics:

  • Dehydration: Excessive peeing can lead to water and electrolyte imbalance if you aren’t drinking enough fluids.
  • Frequent bathroom trips: Needing to urinate often can disrupt sleep and daily activities.
  • Mineral loss: Increased urine output can mean more nutrient loss, including minerals like potassium.

Overall, incorporating some juices with diuretic effects as part of a hydrating and balanced diet can be safe and healthy for most people. But overdoing diuretic drinks, or using them as a detox or weight loss solution, may cause more harm than good.

Tips for minimizing excessive urination from juices

Here are some tips to help prevent too much diuresis when drinking juices:

  • Avoid drinking large amounts of diuretic juices back-to-back.
  • Balance out juices with regular water to stay hydrated.
  • Avoid excessive intake of celery, cranberry, or lemon juice as these have the strongest effects.
  • Monitor your urine output and color. Dark urine or infrequent urination can signal dehydration.
  • Ensure you’re getting enough potassium, sodium, and other electrolytes from your overall diet.
  • Talk to your doctor before using diuretic juices if you take diuretics or have a medical condition affected by fluid levels.

Moderation is key if you want to incorporate juices with diuretic potential into your routine. Pay attention to your body’s signals to avoid overdoing it.


Some fruit and vegetable juices may have mild diuretic effects due to their water and nutrient contents. Juices with the strongest effects include cranberry, lemon, celery, and carrot juice. Drinks like coffee, tea, and alcohol can also stimulate urine production when consumed in excess.

While using diuretic juices can have benefits like reducing fluid retention, they may lead to dehydration or electrolyte imbalance if overdone. Drink juices in moderation as part of an overall healthy diet and stay well hydrated to avoid unwanted frequent urination.
