Is prune juice a good way to detox?

In today’s world, many people are concerned about toxins building up in their bodies. Detoxification, or detox, diets and cleanses have become popular ways to flush out toxins and rejuvenate. But do detoxes really work, and are they safe? Let’s take a closer look at whether drinking prune juice is an effective way to detox the body.

What is Detoxification?

Detoxification, or detox, refers to the process of removing toxins from the body. A detox diet or cleanse typically involves restricting calories, eliminating certain foods, and consuming specific juices, supplements, or other ingredients thought to accelerate toxin elimination.

There are many different types of detoxes, but some of the most common include:

  • Juice cleanses – Consume only fresh vegetable and fruit juices for 3-7 days
  • Smoothie cleanses – Blend and drink only fresh fruit and vegetable smoothies
  • Water fasts – Drink only water for 12-72 hours
  • Teatoxes – Drink specific “detox teas” over a period of time
  • Cleanse supplements – Take OTC supplements or powders that claim to remove toxins

Detoxes promise to deliver a number of health benefits, from rapid weight loss, to improved digestion, clearer skin, and higher energy levels. However, there is little scientific evidence to support these outcomes.

Common Reasons People Detox

There are several reasons why someone might consider doing a detox cleanse:

  • Lose weight quickly
  • Reset eating habits or break bad habits
  • Remove environmental toxins
  • Clear skin or resolve other skin issues
  • Resolve digestive problems
  • Reduce bloating
  • Increase energy levels
  • Improve mental clarity and focus
  • Strengthen immune system
  • Reduce inflammation

However, there is little scientific evidence that detoxes can deliver most of these benefits consistently. At best, any positive effects are usually short-term.

Do Our Bodies Need Help Detoxifying?

Our bodies are highly capable of removing toxins on their own through the liver, kidneys, lungs, skin, and gastrointestinal tract. We don’t need juice cleanses, supplements, or other gimmicks.

In reality, these natural detox organs do their job 24/7 with no need for fasting, cleansing, or special diets. The liver filters blood from the digestive tract before passing it to the rest of the body. It neutralizes and decomposes waste products, drugs, and toxic substances.

The kidneys filter the blood to remove excess water, salts, and waste products, producing urine. Lungs exhale carbon dioxide and other gaseous waste. Skin sweats out fluids and salts. The GI tract moves food through the intestines and colon, eliminating solid waste matter.

So our organs already have the detox process covered. Promoters of cleanses and detoxes often exaggerate the amount of toxins we accumulate from our diets and environments. The truth is our bodies are well-designed detoxification machines.

Potential Risks of Detoxes

While detoxes are usually harmless for most healthy people in the short term, they can be problematic in some cases. Potential risks and side effects include:

  • Hunger, fatigue – from calorie restriction
  • Headaches, irritability – from caffeine withdrawal
  • Diarrhea – from laxative supplements
  • Dehydration, electrolyte imbalance
  • Low blood sugar
  • Nutritional deficits
  • Disordered eating patterns

People with certain medical conditions like diabetes, eating disorders, gastrointestinal issues, heart disease, or those who are pregnant/nursing should not do detox cleanses unless approved by their doctor.

What is Prune Juice?

Now that we’ve reviewed some basics about detoxes, let’s focus our attention on prune juice.

Prune juice is a fruit juice made from dried plums, aka prunes. It contains many nutrients and antioxidants, including:

  • Vitamin A
  • Vitamin K
  • Potassium
  • Copper
  • Boron
  • Phenolic compounds

It also contains a compound called dihydrophenylisatin, which provides its laxative effect. Prune juice has long been used as a remedy for constipation due to its high fiber content and natural laxative properties.

Some key facts about prune juice:

  • Made from dried plums (prunes) and water
  • Contains sorbitol, which has a laxative effect
  • More effective than psyllium for constipation relief
  • Dose of 4-8 ounces recommended for constipation
  • Provides antioxidants, vitamin K, potassium
  • Slightly higher in calories than other fruit juices

Prune Juice Nutrition Facts

Here is the typical nutrition profile of an 8 ounce glass of prune juice made from dried plums:

Nutrient Amount
Calories 182
Total Carbohydrate 45 g
Dietary Fiber 3 g
Total Sugars 38 g
Added Sugars 0 g
Protein 1 g
Vitamin A 10% DV
Vitamin C 3% DV
Calcium 3% DV
Iron 8% DV
Potassium 15% DV

*DV = Daily Value

Prune juice is high in carbohydrates from natural fruit sugars. It provides antioxidants, vitamin K, potassium, and some fiber. It’s lower in protein, calcium, and other vitamins and minerals than whole plums.

Using Prune Juice for Constipation Relief

Drinking prune juice can be an effective remedy for constipation in both the short and long term. Here’s how it helps:

  • Sorbitol: Sorbitol is a sugar alcohol with laxative effects. Prune juice contains approximately 6-8 grams per 4 oz serving.
  • Fiber: Prune juice contains some dietary fiber (3 grams per 8 oz), which adds bulk to stool and helps move it through the intestines.
  • Fluids: Like any juice, prune juice adds fluids to the digestive tract and softens stool.
  • Potassium: Prune juice is high in potassium, an electrolyte that helps regulate fluids in the GI tract.

Studies show prune juice is more effective than fiber supplements like psyllium for chronic constipation relief in adults and children. It provides both immediate and long-term results.

Most experts recommend 4-8 ounces (1/2-1 cup) daily to relieve constipation. It’s best to start with a smaller dose like 4 oz and increase if needed. Results are usually seen in 12-24 hours. Drink plenty of water as well.

Is Prune Juice Effective for Detoxing?

Now that we’ve covered the basics about prune juice, let’s get back to our original question: can drinking prune juice help detoxify the body?

There isn’t any evidence that prune juice can “detox” the body or remove toxins. However, as a natural laxative, it can help promote regular bowel movements and eliminate waste matter from the digestive tract.

During a juice cleanse, prune juice may be consumed to try and increase bowel movements. However, its effects are limited to the GI tract. It cannot improve kidney, liver, or other organ function as some detox claims suggest.

Here is a quick summary of the realistic effects prune juice can (and cannot) have during a detox:

Prune Juice Can: Prune Juice Cannot:
  • Act as a laxative
  • Soften stool
  • Add fluid to the intestines
  • Provide potassium
  • Relieve constipation
  • Detoxify the liver
  • Filter the blood
  • Remove heavy metals
  • Cleanse the kidneys
  • Flush out environmental toxins

So in summary, while prune juice can promote bowel movements as a natural laxative, it does not detoxify the body or remove toxins. Any benefits are limited to the digestive tract.

Healthier Alternatives to Detoxing

Instead of doing juice or detox cleanses, there are much healthier ways to support your body’s detox organs and feel rejuvenated.

Here are some positive steps you can take instead of detoxing:

  • Eat more fruits and vegetables – Get antioxidants, fiber, vitamins, and minerals.
  • Stay hydrated – Drink plenty of water and herbal tea.
  • Exercise regularly – Light activity supports circulation and detox organs.
  • Reduce alcohol – Limit alcoholic drinks to ease the burden on your liver.
  • Quit smoking – Avoid cigarettes to support lung health.
  • Take probiotics – Probiotic foods and supplements aid digestion.
  • Manage stress – Stress hormones can impair detox pathways.
  • Get enough sleep – Quality rest supports all body processes.

Focusing on overall healthy lifestyle choices is the safest and most effective way to support natural detoxification. Be wary of quick fix juice or detox cleanses with little scientific merit.


In summary, there is limited evidence that detox cleanses can remove toxins or provide the benefits often claimed. The body already has its own sophisticated detoxification systems. However, drinking prune juice in moderation can provide constipation relief due to its natural laxative effects.

Rather than doing potentially risky cleanses, focus on healthy diet, lifestyle habits, and supporting natural detoxification pathways. Talk to your doctor before attempting a detox, especially if you have any underlying health conditions.
