We know, we know—your grandma swore by it. But a 2026 Cochrane Review (fancy science speak for “we looked at all the studies”) found that while cranberry juice might reduce UTIs for some folks, the evidence is surprisingly weak. In pregnancy specifically, the data is mixed. Some studies show a mild benefit; others show zero difference. Don’t rely on it as your only defense. Pee after sex, stay hydrated, and listen to your body. And if you think you have a UTI—burning, urgency, weird smells—call your doctor, not your juice bottle.
The real risk isn’t the cranberries themselves—it’s how much you drink. Downing a quart a day can mess with your stomach (hello, acid reflux) or even cause kidney stones in rare cases. Moderation, people. One to two glasses (8 ounces each) per day is the sweet spot. Any more and you’ll turn into a walking, talking cranberry marshmallow.

Can it help with that other pregnancy problem… constipation?
Oh, you mean the fact that you haven’t pooped in three days despite eating a whole bag of prunes? Cranberry juice has a little fiber, but it’s not a miracle worker. It’s not a laxative, so don’t chug it hoping for a colon blowout. Instead, eat the whole berries (canned or fresh) for fiber. Or, you know, call your pharmacy for a gentle stool softener. No shame in the pregnancy game.
Now, let’s talk about flavor. Pure, unsweetened cranberry juice is the most aggressive, puckeringly sour liquid on the planet. It’s like drinking battery acid that’s been filtered through a lemon’s revenge fantasy. So dilute it with water or seltzer. Add a splash of apple juice. Or blend it with a banana. You’re not a martyr—you deserve palatable hydration.
