Cranberry juice typically contains about 14 mg of vitamin C per 100 ml, making it a good source, but daily intake should complement other vitamin C sources.
Cranberry juice packs a powerful vitamin C punch, offering about 24 mg per 8-ounce serving – that’s 30% of your daily value. But this tart red beverage provides far more than just immune support. From urinary tract health to antioxidant benefits, cranberry juice delivers unique advantages that make it worth incorporating into your diet.
How Much Vitamin C Does Cranberry Juice Contain?
An 8-ounce glass of pure cranberry juice provides approximately 24 mg of vitamin C, meeting about 30% of the recommended daily intake for most adults. This makes it a significant source of this essential nutrient, though slightly less concentrated than orange juice.
| Juice Type | Vitamin C per 8 oz | % Daily Value |
|---|---|---|
| Cranberry Juice | 24 mg | 30% |
| Orange Juice | 124 mg | 138% |
| Apple Juice | 2 mg | 2% |
Factors Affecting Vitamin C Content
The actual vitamin C content can vary based on:
- Processing methods (fresh vs. concentrate)
- Storage conditions and duration
- Added ingredients like sweeteners
For maximum vitamin C retention, choose cold-pressed cranberry juice and store it properly. Cold-pressed juices typically retain more nutrients than heat-processed alternatives.
Beyond Vitamin C: Cranberry Juice’s Nutritional Profile
While vitamin C gets much attention, cranberry juice contains other valuable nutrients:
Key Nutrients in 8 oz Cranberry Juice
- Vitamin E: 20% DV
- Vitamin K: 18% DV
- Manganese: 17% DV
- Copper: 7% DV
Powerful Antioxidants
Cranberries are rich in unique antioxidants including:
- Anthocyanins (give the red color)
- Proanthocyanidins (particularly A-type)
- Quercetin
- Myricetin
These compounds work synergistically with vitamin C to protect cells from oxidative damage. Research suggests they may be particularly beneficial for vegetable and fruit juice blends that combine multiple antioxidant sources.
Health Benefits of Cranberry Juice
1. Urinary Tract Health
The A-type proanthocyanidins in cranberries may prevent bacteria from adhering to bladder walls. While studies show mixed results, a 2025 meta-analysis of 23 trials found cranberry products reduced UTI frequency in susceptible individuals by 30-40%.
2. Heart Health Support
Cranberry juice’s antioxidants may help:
- Reduce LDL cholesterol oxidation
- Improve blood vessel function
- Lower blood pressure
3. Digestive Benefits
The juice’s compounds may promote gut health by:
- Supporting beneficial bacteria
- Inhibiting H. pylori growth
- Reducing gut inflammation
Choosing the Best Cranberry Juice
To maximize benefits:
What to Look For
- 100% pure cranberry juice (not cocktail)
- No added sugars
- Cold-pressed when possible
- Organic options to reduce pesticide exposure
What to Avoid
- “Cranberry juice cocktail” (high in added sugar)
- Artificially sweetened varieties
- Overly processed or from concentrate
For those watching sugar intake, consider making your own juice using a quality juicer and adding small amounts of other fruits for natural sweetness.

Vitamin C Synergy With Other Nutrients
Cranberry juice’s vitamin C works particularly well with:
