These two get lumped together because they look similar in the glass, both taste tart, and both come with health claims. But they're fundamentally different juices with different strengths.
Neither one is objectively "better." It depends on what you're drinking it for.
The Big Comparison Table

| Heart health | Strong evidence for blood pressure, arterial plaque | Some evidence for cholesterol | Pomegranate |
| Sugar per 250ml | ~32g (100% juice) | ~30g (100% juice) or ~9g (light/diet) | Cranberry (more low-sugar options) |
| Calories per 250ml | ~135 kcal | ~115 kcal (100% juice) | Cranberry (slightly) |
| Taste | Sweet-tart, fruity, rich | Sharp, astringent, sour | Personal preference |
| Price (Canadian) | $0.80–1.40/250ml | $0.30–0.70/250ml | Cranberry (much cheaper) |
UTI Prevention: Cranberry Wins This One
Let's get this out of the way: if you're drinking juice specifically to prevent urinary tract infections, cranberry is the clear choice. Pomegranate juice doesn't have meaningful evidence for UTI prevention.
Cranberry's UTI mechanism involves proanthocyanidins (PACs) — specifically A-type PACs — that prevent E. coli bacteria from adhering to the urinary tract wall. A 2023 Cochrane review (Williams et al., Cochrane Database of Systematic Reviews) analyzed 50 trials and concluded that cranberry products reduce the risk of UTIs by about 25–30%, particularly in women with recurrent infections.
Pomegranate juice has some in-vitro antibacterial activity, but no clinical trials showing UTI prevention in humans. If UTIs are your concern, reach for the cranberry. Our page on pomegranate and kidney health covers the urinary system in more detail.
Antioxidants: Pomegranate Dominates
Pomegranate juice has roughly double the antioxidant capacity of cranberry juice, measured by ORAC (Oxygen Radical Absorbance Capacity), FRAP, and DPPH assays. This was demonstrated by Seeram et al. (2008, Journal of Agricultural and Food Chemistry), who compared the antioxidant activity of 10 common polyphenol-rich beverages.
Pomegranate juice ranked #1, ahead of cranberry, blueberry, grape, and green tea. The gap wasn't close — pomegranate's total antioxidant potency index was nearly double cranberry's.
The key antioxidant compounds are different too. Pomegranate delivers punicalagins and ellagitannins (which convert to urolithin A in the gut). Cranberry delivers anthocyanins, quercetin, and those A-type PACs. Different compounds, different benefits.
Heart Health: Pomegranate Has Stronger Evidence
For cardiovascular benefits, pomegranate juice has substantially more clinical evidence. Multiple trials show reductions in systolic blood pressure (Aviram et al., 2004; Sahebkar et al., 2017 meta-analysis), reduced arterial plaque thickness, and improved cholesterol profiles.
Cranberry juice has some evidence for improving HDL cholesterol and reducing oxidized LDL, but the effect sizes are smaller and the evidence base is thinner. Full details on our heart health page.
Sugar Content: It's Complicated
100% pure pomegranate juice and 100% pure cranberry juice have similar sugar content — around 30–32g per 250ml. But here's the thing: almost nobody drinks 100% cranberry juice straight. It's brutally tart.
Most cranberry juice sold in Canada is cranberry cocktail or cranberry blend, which adds sugar or uses sweeteners. Ocean Spray Cranberry Cocktail has about 28g of added sugar per 250ml on top of the natural sugars. Ocean Spray Light uses sucralose to get the sugar down to ~2g.
Pomegranate juice is typically sold and consumed as 100% juice — no added sugar needed because it's naturally sweet enough. Check our sugar content breakdown for brand-by-brand numbers.
If you compare 100% pure to 100% pure, the sugar is nearly identical. If you compare what people actually buy and drink, cranberry cocktails have more total sugar (natural + added), while light/diet cranberry options have less.
For diabetics or people watching blood sugar: cranberry light is the lower-sugar option. Pure pomegranate juice has ~32g of natural sugars with no light version widely available.
Taste Comparison
Pomegranate juice is sweet with tartness underneath. Most people enjoy it straight — it's rich, fruity, and complex. Even people who don't love tart flavours usually find pomegranate juice palatable.
Pure cranberry juice is aggressively sour. Like, pucker-your-face sour. That's why cranberry cocktail exists — the pure stuff is hard to drink for most people. Cranberry cocktail is milder but heavily sweetened.
In cocktails and mocktails, pomegranate juice adds more complexity. Cranberry juice adds sharp acidity. Both have their place in the bar.
Cost in Canada
| Product | Store | Price | Per 250ml |
|---|---|---|---|
| POM Wonderful 1.4L | Costco | $9.99 | $1.78 |
| POM Wonderful 473ml | Loblaws | $5.49 | $2.90 |
| Ocean Spray 100% Cranberry 1L | Loblaws | $4.99 | $1.25 |
| Ocean Spray Cocktail 1.89L | Costco (2-pack) | $8.99 | $0.59 |
| Patience Fruit Organic Cranberry 1L | Metro | $7.99 | $2.00 |
Cranberry juice is meaningfully cheaper than pomegranate juice across the board. If budget is the primary driver, cranberry wins on cost. More pricing details for pomegranate on our Canadian price guide.
Can You Mix Them?
Absolutely. Pomegranate-cranberry blends exist (Tropicana makes one), and mixing them at home is easy. The cranberry's sharpness cuts the sweetness of the pomegranate, and you get the polyphenol profiles of both.
A 50/50 blend makes a pretty good daily drink. You get the cranberry PACs for urinary health and the pomegranate punicalagins for cardiovascular benefits, at a lower cost than pure pomegranate.
Buy pomegranate juice if: You want the broadest antioxidant coverage, cardiovascular benefits, or enjoy the flavour. You're okay with the higher price.
Buy cranberry juice if: UTI prevention is your primary goal, you want a cheaper daily juice, or you need a low-sugar option (light varieties).
Buy both if: You want the benefits of each. Alternate days or blend them. This is honestly the best approach if your budget allows — they complement each other rather than compete.
How They Compare to Other Juices
We've also compared pomegranate juice head-to-head with grape juice (for heart health and antioxidant rankings), beet juice (for blood pressure and nitric oxide), and tart cherry juice (for inflammation and sleep). Each comparison reveals different strengths.
