Cranberry juice can be low in calories, especially if unsweetened, typically containing about 45-60 calories per 8 oz serving, making it a healthier choice.
Cranberry juice is often marketed as a healthy, low-calorie drink, but the truth depends on the type you choose. While pure, unsweetened cranberry juice contains just 45-50 calories per 8-ounce serving, many commercial varieties pack added sugars that significantly increase calorie content. Understanding these differences helps you make smarter beverage choices.
Cranberry Juice Calorie Breakdown
The calorie content of cranberry juice varies dramatically based on preparation methods:
| Type | Calories (per 8oz) | Sugar Content |
|---|---|---|
| Unsweetened 100% juice | 45-50 | 12g natural sugars |
| Juice cocktail | 110-150 | 30-40g (added sugars) |
| Diet/low-calorie versions | 10-25 | Artificial sweeteners |
Why Unsweetened Cranberry Juice is Naturally Low-Calorie
Cranberries themselves are low in natural sugars compared to other fruits. According to Ocean Spray, their unsweetened juice contains only the natural fruit sugars from cranberries. The tart flavor comes from high concentrations of organic acids like quinic, malic, and citric acids.
Health Benefits Beyond Low Calories
Research shows cranberry juice offers significant health advantages when consumed in its pure form:
- Antioxidant powerhouse: Contains polyphenols that combat oxidative stress
- Urinary tract health: Proanthocyanidins prevent bacterial adhesion
- Heart health: May improve HDL cholesterol levels (NIH study)
- Vitamin C source: Provides 25% DV per serving
Making Smart Cranberry Juice Choices
For maximum health benefits with minimal calories:
- Look for “100% juice” with no added sugars
- Check labels – ingredients should list only cranberry juice
- Consider diluting with water or sparkling water
- Make your own using a quality juicer
Cranberry Juice in Weight Management
While not a magic weight loss solution, unsweetened cranberry juice can support calorie-controlled diets when used properly:
- Provides flavor without excessive calories

Potential Downsides to Consider
Despite benefits, be aware of these factors:
- Tart flavor often leads manufacturers to add sugars

As research from the National Institutes of Health confirms, “low-calorie cranberry juice significantly reduces lipid oxidation and increases plasma antioxidant capacity.”
