Prune juice has long been celebrated as a natural remedy for constipation, but its sugar content often raises questions. This comprehensive guide examines prune juice’s nutritional profile, compares it to whole prunes, explores its health benefits, and provides practical tips for consumption. Whether you’re managing digestive issues or simply monitoring your sugar intake, understanding prune juice’s sugar content is essential for making informed dietary choices.
Prune Juice Nutrition: Sugar Content and Key Facts
Standard Nutritional Values
An 8-ounce (240ml) serving of prune juice typically contains:
| Nutrient | Amount | % Daily Value* |
|---|---|---|
| Calories | 176 | 9% |
| Total Carbohydrates | 43g | 16% |
| Sugars | 41g | 82% |
| Fiber | 3g | 11% |
| Protein | 2g | 4% |
*Based on a 2,000 calorie diet
Types of Sugar in Prune Juice
Prune juice contains three main types of sugars:
- Natural fructose: The primary sugar found in fruits
- Glucose: A simple sugar that provides quick energy
- Sorbitol: A sugar alcohol with laxative properties (about 14.7g per 100g of prunes)
Prune Juice vs. Whole Prunes: Nutritional Comparison
| Nutrient | Prune Juice (8oz) | Whole Prunes (5 pieces, 40g) |
|---|---|---|
| Calories | 176 | 100 |
| Sugar | 41g | 12g |
| Fiber | 3g | 3g |
| Sorbitol Content | Lower (processing reduces levels) | Higher (more effective laxative) |
| Glycemic Index | Higher (juice form absorbs faster) | Lower (fiber slows absorption) |
Key Differences
- Fiber loss: Juicing removes insoluble fiber found in whole prunes
- Concentration: Juice packs more sugar per volume than whole fruit
- Satiety: Whole prunes are more filling due to fiber content
Health Benefits of Prune Juice
Digestive Health
Prune juice’s effectiveness for constipation comes from three components:
- Sorbitol: Draws water into intestines to soften stool
- Pectin: A soluble fiber that feeds gut bacteria
- Polyphenols: Plant compounds with anti-inflammatory effects
Clinical Evidence
A 2022 study of 84 chronic constipation patients found:
- 54g daily prune juice improved bowel movement frequency
- Softer stools without diarrhea or excessive flatulence
- No adverse effects reported over 8 weeks
Additional Health Benefits
- Bone health: Rich in boron and vitamin K for bone density
- Heart health: Potassium helps regulate blood pressure
- Antioxidants: Neutralizes free radicals that damage cells

Frequently Asked Questions
How quickly does prune juice work for constipation?
Effects vary from 2-8 hours depending on individual metabolism and severity of constipation. For best results, consume on an empty stomach in the morning.
Can prune juice help with weight loss?
While it may support digestion, prune juice’s high sugar content makes it calorie-dense. Whole prunes are better for weight management due to higher fiber content.
Is prune juice safe for children?
Yes, in small amounts (1-2oz diluted with water). However, consult a pediatrician first, especially for children under 1 year.
Key Takeaways
- Prune juice contains 41g sugar per 8oz serving – mostly natural but still significant
- Whole prunes offer similar benefits with less sugar impact and more fiber
- Effective constipation relief comes from sorbitol, not just fiber content
- Moderation is key – limit to 4-6oz daily and dilute when possible
- Consider alternatives if monitoring blood sugar or calorie intake
Prune juice can be part of a healthy diet when consumed mindfully. For occasional constipation relief, its benefits often outweigh its sugar content. However, those with frequent digestive issues should consult a healthcare provider to address underlying causes rather than relying solely on prune juice.
