You’ve probably heard it before. Cranberry juice stops urinary tract infections. Your mum told you. Your doctor mentioned it. But is it actually true?
The short answer? Not really. The science is more complicated than the myth.
What Does the Research Say?
Scientists have studied cranberry juice for years. They wanted to know if it truly prevents UTIs. The results were surprising.
Most studies found little evidence that cranberry juice prevents infections. A major review looked at multiple studies together. It found no clear benefit for most people.
However, some research showed a small benefit for certain groups. Women with repeat infections might see a slight improvement. But the effect was modest. It was not a cure.
Why Do People Believe in Cranberries?
Cranberries contain a compound called proanthocyanidin. This substance stops bacteria from sticking to the bladder wall. In theory, this sounds perfect. In practice, it doesn’t work well enough for most people.
The problem is simple. You need a lot of cranberry juice to get enough of this compound. Most people won’t drink that much. And shop-bought juice often has added sugar. Too much sugar can actually make infections worse.
What Actually Prevents UTIs?
Drinking plenty of water is far more effective. When you drink enough water, you pass more urine. This flushes bacteria out of your system. It’s straightforward and it works.
Other prevention methods are proven to help. Urinating after sex reduces infection risk. Wiping from front to back matters too. These simple habits make a real difference.
Some people are at higher risk for UTIs. Post-menopausal women experience more infections. Elderly people face special challenges. These groups need extra attention to prevention.
Dehydration is a known risk factor. Drinking enough fluids is essential for bladder health. It’s one of the best things you can do.
Other Foods and Drinks to Consider
What you eat matters for bladder health. Certain foods and drinks should be avoided. Caffeine, alcohol and spicy foods can irritate your bladder. These might make infections more likely.
A healthy diet supports overall bladder function. But no single food will prevent infections on its own.
Do You Have a UTI Right Now?
If you think you have a UTI, don’t delay. Recognising the symptoms early is important. Pain when urinating is the main sign. You might also feel an urgent need to go. Cloudy urine is another common symptom.

You can get a home test for UTIs. Testing at home is convenient. A professional urine test confirms infection.
Prevention Works Best
The bottom line is this. Cranberry juice alone won’t prevent UTIs. But prevention methods do work. Drinking water, good hygiene and bladder awareness all help.
Pelvic floor health is also important. Strong pelvic floor muscles support bladder function. Simple tips keep your bladder healthy as you age.
Science matters. It shows us what actually works. Cranberry juice sounds nice. But water, hygiene and healthy habits work better. Focus on proven prevention methods. Your bladder will thank you.
