Is this trial a fit for you?

Likely a good fit

Adults aged 18–65 with prediabetes (impaired fasting glucose, impaired glucose tolerance, or HbA1c 5.7–6.4%), BMI 20–35 kg/m², stable weight, and not taking antidiabetic medications are the intended participants.

Probably not a fit

People taking medications that affect glucose metabolism, those with liver or kidney disease, heavy alcohol use, known allergy to product components, recent trial participation, or who fall outside the age/BMI limits are unlikely to benefit from this intervention.

What this trial studies

This randomized, double-blind, placebo-controlled trial will compare a liquid nutritional product containing carob extract to a matching placebo over 90 days in adults with glucose intolerance. Eligible participants are 18–65 years old with impaired fasting glucose, impaired glucose tolerance, or HbA1c 5.7–6.4% and BMI 20–35 kg/m², and are not taking antidiabetic medications. Primary outcomes include glucose response during an oral glucose tolerance test (AUC and peak), changes in fasting glucose, HbA1c, basal insulin, and insulin resistance indices (HOMA-IR, QUICKI); body composition and safety/tolerability will also be recorded. The single-center study is conducted at UCAM HiTech in Murcia, Spain with scheduled metabolic testing and follow-up visits.

Why it matters

Potential benefit: If successful, this could offer a safe, non-drug option to help lower blood sugar and reduce insulin resistance in people with prediabetes.

How similar studies have gone: Small human and animal studies of carob extracts or fiber-rich carob products have suggested modest improvements in postprandial glucose, but large randomized trials in prediabetes are limited.
