Cranberry for Crohn's Disease
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests whether a cranberry-based supplement can improve gut health in people with Crohn's disease. Crohn’s disease often causes an imbalance in gut bacteria, and cranberry compounds might help restore this balance. Participants will take either a cranberry supplement or a placebo for 10 weeks and provide samples for researchers to study changes in gut bacteria and inflammation. This trial suits adults with Crohn's disease who experience a moderate to severe impact on daily life and can regularly consume the supplement. As an Early Phase 1 trial, participants will be among the first to help researchers understand how this new treatment works in people.
Will I have to stop taking my current medications?
The trial requires that your current medications be stable before starting. You don't need to stop them, but they should be at a stable dose for a certain period before the trial begins.
Is there any evidence suggesting that this treatment is likely to be safe for humans?
Research shows that cranberry extract powder is generally safe when used in food. One study found it safe at the suggested amounts. Animal studies of colitis, a condition similar to Crohn's disease, have shown that cranberry products can help with inflammation.
Cranberry has long been used to reduce the risk of urinary tract infections, indicating it is well-tolerated. Although cranberry is not specifically approved for Crohn's disease, its use in other areas suggests it is safe. However, since this is an early phase trial, researchers are still learning about its safety for people with Crohn's disease. Participants should consider this when deciding to join the trial.12345Why do researchers think this study treatment might be promising?
Unlike the standard treatments for Crohn's Disease, which often involve medications like corticosteroids or immune system suppressors, cranberry powder is a natural product that may offer a gentler alternative. Researchers are intrigued by cranberry's unique active compounds, such as proanthocyanidins, which are thought to have anti-inflammatory and antioxidant properties. These compounds might help reduce inflammation in the digestive tract without the side effects associated with conventional drugs. This novel approach could pave the way for a more holistic and less invasive treatment option for those with Crohn's Disease.
What evidence suggests that cranberry powder might be an effective treatment for Crohn's disease?
Research suggests that cranberry supplements might improve gut health in people with Crohn's disease. Some studies have shown that cranberry can reduce gut inflammation, a key factor in Crohn's disease. For example, one study found that cranberry extract reduced the severity of gut inflammation in mice. Another study discovered that short-term cranberry use increased the variety of beneficial gut bacteria. In this trial, participants in the intervention arm will receive cranberry whole powder to evaluate its potential in managing Crohn's disease symptoms by promoting a healthier gut environment.13678

What Are the Treatments Tested in This Trial?
Interventions
- Cranberry powder
Trial Overview
The trial is testing if a daily cranberry supplement improves gut health in Crohn's patients over 10 weeks versus a placebo. It measures the effects on gut bacteria balance, inflammation, and overall health through questionnaires and blood, urine, stool samples collected at four times during the study.
