Research Overview

Omentin-1

Lower omentin-1 levels are often associated with obesity, insulin resistance, and metabolic syndrome. Research continues on its use as a biomarker and as a mechanistic lead for AMPK-linked metabolic interventions.

Oxyntomodulin

Human studies showed acute reductions in food intake and modest weight loss, helping establish the GLP-1 and glucagon co-agonism concept. It remains a foundational peptide for obesity and satiety research.
