Study
Cranberry Capsules Show No Impact on Urinary Health in Older Women in Nursing Homes
A study found that cranberry capsules did not significantly reduce urinary tract issues in older women living in nursing homes.
Summary
In plain language
A recent study explored whether taking cranberry capsules could improve urinary health in older women residing in nursing homes. The researchers found that there was no significant difference in urinary health between those who took cranberry capsules and those who took a placebo over a year. This means that, for older women living in nursing homes, cranberry capsules may not offer the benefits many hope for in terms of preventing urinary issues. It's always a good idea to discuss with your healthcare provider about the best ways to maintain urinary health.
Details
Use the full description to understand the study design, methods, and the limits of the findings.
This study was a double-blind, randomized trial that involved 185 women aged 65 and older, living in nursing homes. Participants were given either cranberry capsules or placebo capsules daily for a year.
The study found no significant difference in the presence of urinary issues between the two groups.
Specific findings included similar rates of urinary tract infections, hospitalizations, and antibiotic use between the groups.
While cranberry capsules are often considered for urinary health, this study suggests they may not be effective in this setting.
It's important to consult with your healthcare provider about the most effective measures for your urinary health needs.
