Does drinking cranberry juice really help with UTIs?


You many have heard that cranberry juice can help urinary tract infections (UTIs), but are these berries really that effective?

Cranberries contain many nutrients and fiber. In addition, researchers believe that cranberry juice is also highly effective in the treatment of heart disease, cancer and infections. Thanks to its high concentration of antioxidants and phytochemical nutrients, cranberries are definitely a step towards a healthy lifestyle.

But before you rush out and buy cartons of cranberry juice, let’s understand the pros and cons of consuming cranberry products.

According to WebMd, there may be more cons than pros:

The Pros

  • One study looked at women who had a history of urinary tract infections caused by E. coli bacteria. Women who drank 1.7 ounces of cranberry-lingonberry juice concentrate every day for six months lowered their risk of getting a UTI by 20% compared to women who didn’t use any intervention.
  • In another study, cranberry juice and cranberry tablets were linked to fewer patients who experienced at least one symptomatic UTI. In the study, sexually active women took one tablet of concentrated cranberry twice a day, drank about 8 ounces of pure unsweetened cranberry juice three times a day for 12 months, or were given a placebo.
  • In a third study, older adults who ate cranberry products were about half as likely to have bacteria and white blood cells in their urine in the setting of no UTI symptoms — a sign of urinary tract infections. But other studies in older people showed no difference in symptomatic UTI in people using cranberry and those who didn’t.

The Cons

  • First, cranberries don’t seem to work for everyone. Although they may appear to help prevent symptomatic urinary tract infections in some women who are at risk for them, there’s no real evidence that cranberries offer any benefit to other groups of people, such as children or seniors.
  • Cranberries don’t prevent bacteria from growing in the urinary tract — they just make it harder for the bacteria to take hold. Cranberry juice also doesn’t treat urinary tract infections once they’ve started.
  • Because of their acidity, cranberries can be hard for some people to take. Up to half of people in studies dropped out because of unpleasant side effects like gastroesophageal reflux disease (GERD), upset stomachnausea, and diarrhea. Many people in the studies also balked at the tart-sweet taste day after day. People who don’t like cranberry juice might find cranberry tablets easier to swallow.
  • In addition to its positive effects, cranberry juice can also have a negative effect on the urinary tract. Cranberry juice is high in salts called oxalates. When people drink a lot of cranberry juice, these salts can crystallize into hard urinary oxalate stones, especially in people who already tend to get these types of stones.
  • People who take the blood-thinning medication warfarin should avoid cranberry products because cranberries can interact with warfarin and cause excess bleeding.
  • Drinking cranberry juice or taking cranberry pills isn’t cheap. The cost can add up to $1,400 a year for cranberry juice and $624 a year for pills.
