Cranberry Extract May Promote Urinary Tract Health
A urinary tract infection (UTI) is an infection in the urinary system, which includes the bladder and the kidneys. When a person has a urinary catheter, germs can travel along the catheter and cause an infection in the bladder or kidney. A recent study suggests that supplementation with a standardized cranberry extract may help reduce the occurrence of UTIs associated with urinary catheterization.
Participants in the study included 64 adults who received post-surgical urinary catheterizations. They were given 120 mg or 240 mg of the standardized cranberry extract, the antibiotic nitrofurantoin or received standard management (SM) care daily for 4 weeks. The researchers evaluated the occurrence of UTIs during the supplementation period.
Participants in the cranberry groups experienced fewer UTIs and UTI symptoms compared to the antibiotic and SM groups. They also saw less presence of bacterial contamination in the urine compared to the antibiotic and SM groups. In addition, participants in the cranberry groups did not experience a UTI in the 3 months following supplementation, compared to an 18% recurrence of UTIs in the antibiotic and SM groups.
The study was conducted by researchers from G D’Annunzio University. It was published online ahead of print on October 10, 2021 in the Journal of Dietary Supplements.
