What this trial studies

This trial investigates the impact of SugarCut® Unripe Guava Fruit Extract on blood glucose levels in adults with prediabetes. It employs a double-blind, placebo-controlled design, randomly assigning participants to either the guava extract group or a placebo group. Over eight weeks, subjects will undergo fasting blood tests and health evaluations at the start, and at four and eight weeks into the trial. The study aims to determine if the guava extract can effectively regulate blood sugar levels.

Who should consider this trial

Good fit: Ideal candidates are adults aged 20-60 with fasting blood glucose levels between 100 and 126 mg/dL.

Not a fit: Patients with renal insufficiency, cancer, or those on blood sugar regulation medications may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a natural dietary supplement option for managing blood glucose levels in prediabetic patients.

How similar studies have performed: Preliminary research has shown promise for guava extracts in blood sugar regulation, suggesting potential success for this approach.
