Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 to 65 with chronic kidney disease stages G3a-G4 who have been under nutritional monitoring for at least six months.

Probably not a fit

Patients with unstable health conditions, those unable to exercise, or those with certain comorbidities may not benefit from this study.

What this trial studies

This clinical trial investigates the effects of beetroot extract supplementation combined with an exercise protocol on patients with chronic kidney disease (CKD). The study employs a randomized, double-blind, placebo-controlled design to assess both acute and chronic impacts of beetroot juice on inflammation and oxidative stress in CKD patients. Participants will undergo nutritional monitoring and exercise familiarization, followed by data collection on various health metrics. The goal is to determine if beetroot can improve health outcomes for CKD patients through its bioactive compounds.

Why it matters

Potential benefit: If successful, this approach could enhance the management of chronic kidney disease by reducing inflammation and oxidative stress, potentially improving patient outcomes.

How similar studies have gone: While the specific combination of beetroot supplementation and exercise in CKD patients is novel, previous studies have shown positive effects of dietary interventions and exercise on kidney health.
