What this trial studies

This clinical trial investigates the effectiveness of pumpkin seed extract in managing blood sugar levels among individuals classified as subhealthy. It employs a randomized, double-blind, placebo-controlled design, comparing low and high doses of the extract against a placebo. Participants will be monitored for changes in fasting blood sugar and glycated hemoglobin levels over the course of the study. The aim is to determine if pumpkin seed extract can provide a beneficial effect on blood sugar management.

Who should consider this trial

Good fit: Ideal candidates are individuals with fasting blood sugar levels between 100 to 125 mg/dL and glycated hemoglobin levels from 5.7 to 6.4%.

Not a fit: Patients with diagnosed type I or II diabetes, severe chronic diseases, or those with allergies to pumpkin seeds will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could offer a natural supplement option for improving blood sugar levels in individuals at risk of diabetes.

How similar studies have performed: While the specific use of pumpkin seed extract is novel, similar studies on natural supplements for blood sugar management have shown varying degrees of success.
