Gut Microbiome and Metabolic Health Study

Recruiting now · Phase 2 · Has a placebo group

Conditions studied: Healthy Volunteers

In brief

The goal of this clinical trial is to assess whether TRPTI (oleoylethanolamide) can reduce plasma imidazole propionate levels and improve insulin sensitivity and metabolic health in healthy adults aged 18 years and above with BMI 18.5-29.9 kg/m². The main question it aims to answer is does TRPTI reduce plasma imidazole propionate (a gut microbiota-derived metabolite linked to insulin resistance)? Researchers will compare TRPTI 300 mg to placebo in a parallel design to see if TRPTI reduces imidazole propionate levels and improves metabolic health markers compared to placebo. Participants will: * Take 2 capsules of their assigned study product daily for 8 consecutive weeks * Attend 3 clinic visits (at baseline, week 4 and week 8)
