How much prune juice to drink for detox?


Detoxification, or detox, has become a popular health trend. The goal of a detox is to eliminate toxins from the body. Some people use detoxes with the hope of improving energy, promoting weight loss, or reducing bloating. Prune juice is commonly used as part of detox plans due to its mild laxative effects. But how much prune juice should you drink to get the desired detox benefits without causing unintended side effects?

What is Prune Juice?

Prune juice is a fruit juice made from dried plums, also known as prunes. Prunes contain high amounts of dietary fiber, sorbitol, and phenolic compounds. The combination of fiber, sorbitol, and phenolics give prune juice its laxative effects by drawing water into the intestines, stimulating bowel movements, and promoting elimination (1).

Some key nutrients found in an 8 ounce glass of prune juice include (2):

  • 184 calories
  • 0.5 g fat
  • 45.6 g carbohydrates
  • 3.2 g protein
  • 7.1 g dietary fiber
  • Potassium, vitamin C, vitamin K

Prune juice has been used as a folk remedy for constipation for decades. Research shows that it can be effective for reducing constipation in children and adults when consumed in adequate amounts (3, 4).

Recommended Dosage of Prune Juice

There is no standard recommended dosage for prune juice. General guidelines suggest the following based on your goals:

  • For constipation relief: 2-6 ounces per day (5)
  • As part of a detox: 6-12 ounces per day. Up to 24 ounces may be used for more aggressive colon cleansing.

It’s best to start with a smaller amount, such as 4-6 ounces per day, to assess your tolerance. You can gradually increase the dosage if needed.

Prune juice can produce bowel movements within a few hours of consumption. However, results may vary based on the individual.

How Often Should You Drink Prune Juice When Detoxing?

Most detox programs recommend drinking prune juice 1-3 times per day. Here are some guidelines based on frequency:

  • Once daily: 4-6 ounces
  • Twice daily: 4-8 ounces per serving
  • Three times daily: 2-6 ounces per serving

Spreading out your intake into multiple smaller servings throughout the day can help minimize unintended side effects.

Some detox plans start with more aggressive dosing of 12-24 ounces daily for 2-3 days to prompt a colon cleanse. Then they reduce to a more moderate intake. Keep in mind that dramatic increases in fiber intake can trigger abdominal discomfort, diarrhea or other gastrointestinal issues for some people. Slow ramp-ups are recommended.

Benefits of Prune Juice for Detoxing

Here are some of the ways that prune juice supports the body’s detoxification process:

  • Relieves Constipation. Constipation causes waste and toxins to linger in the intestines. Prune juice stimulates bowel movements to clear out backed up waste.
  • Supports Regularity. Drinking prune juice throughout a detox provides fluid and fiber to keep bowels moving regularly.
  • Improves Gut Health. Prune juice contains prebiotics that feed beneficial probiotic bacteria in the gut. A healthy gut optimizes detoxification.
  • Cleanses the Colon. With higher doses, prune juice prompts bowel movements to wash out the entire colon.
  • Promotes Hydration. The fluid in prune juice helps prevent dehydration during a cleanse.
  • Provides Antioxidants. Prunes contain antioxidants that protect against toxins and oxidative stress.

By stimulating regular bowel movements and cleansing the GI tract, prune juice creates optimal conditions for eliminating toxins from the body.

Side Effects to Watch For

Prune juice is generally safe when consumed according to recommendations. However, there are some potential side effects to be aware of:

  • Abdominal pain or cramps
  • Bloating
  • Excessive gas
  • Diarrhea
  • Electrolyte imbalances
  • Dehydration

Prune juice contains sorbitol, a sugar alcohol that can ferment in the gut causing uncomfortable gas and bloating (6). Starting with small servings can allow your body to adjust. Diarrhea and dehydration are mainly risks with excessive intake.

If you experience any concerning side effects, reduce your dosage or stop drinking prune juice. Make sure to drink plenty of water and consult your healthcare provider if significant issues arise.


Here are some precautions to keep in mind with drinking prune juice:

  • Avoid extremely high doses.
  • Introduce it gradually if new to high fiber intake.
  • Drink plenty of water.
  • Don’t give to children under 1 year old.
  • Monitor electrolytes if consuming for more than 1-2 weeks.
  • Consult your doctor about potential medication interactions.
  • Talk to your doctor before use if you have a chronic condition like diabetes, kidney disease, or irritable bowel disease.

While prune juice can be a helpful detoxification aid, it’s important to incorporate it thoughtfully. Be sure to discuss with your doctor before adding it if you have any concerns.

The Best Time to Drink Prune Juice

The optimal time to drink prune juice depends partially on your goals:

  • For constipation relief: Drink prune juice in the morning on an empty stomach. This allows time to prompt a bowel movement later in the day.
  • For detox/cleanse: Some programs recommend starting the day with a large serving such as 8-12 oz to flush out the system first thing. Then sip smaller servings throughout the day for continued benefits.

Drinking prune juice about 30 minutes before meals can aid digestion. Allow at least 2 hours after taking medications or supplements since prune juice can impact absorption time.

Aim to drink the final serving at least 2-3 hours before bedtime. Prune juice could stimulate middle of the night bowel movements if consumed too close to sleeping. Finding the ideal prune juice schedule may require some trial and error.

Tips for Drinking Prune Juice

Here are some tips for incorporating prune juice into your detox routine:

  • Gradually increase serving sizes to avoid GI distress.
  • Dilute it with water if the taste is too strong.
  • Enjoy chilled or heated based on your preference.
  • Blend it into a fruit smoothie with bananas or apples.
  • Pair with a source of protein like Greek yogurt or nut butter.
  • Don’t give up if you don’t see immediate results.
  • Combine with exercise, hydration, and a healthy diet for optimal detox benefits.

Adding some lemon, cinnamon, ginger or other spices can improve the flavor. Prune juice combines especially well with apple cider, pear nectar, or carrot juice.

Detox Flush With Prune Juice

Some detox programs use prune juice as part of an intensive colon cleanse. This may involve drinking 32-64 ounces of diluted prune juice within a short time span, such as over 2-4 hours (7).

This large volume prompts substantial bowel movements to wash out the entire colon. Always start with a lower amount if attempting this type of detox flush. Stay near a restroom, drink plenty of water, and modify as needed if you experience adverse reactions.

Prune Juice Detox Recipe

If you find the taste of straight prune juice to be unappealing, try diluting it in a fruit smoothie. Here is a prune detox smoothie recipe to get you started:

You can modify this smoothie by using almond milk instead of water or substituting different frozen fruits like mango. Sip this detoxifying prune juice smoothie for breakfast or a midday snack.


Prune juice is an effective, natural laxative that can be used to aid detoxification. A moderate intake of 4-8 ounces taken 1-3 times daily offers the benefits of relieving constipation, supporting gut health, and promoting the elimination of waste and toxins from the body. Larger flush doses may be used periodically in some intensive colon cleanse regimens. However, excessive consumption can produce side effects like diarrhea or abdominal pain. Drinking prune juice as part of a balanced detox program that includes adequate hydration, healthy eating, and exercise habits can optimize results while minimizing risks. Work with your healthcare provider to determine appropriate dosage and schedule based on your health needs and detox goals.
