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.
Kisspeptin-52
Human and animal studies show kisspeptin-52 can acutely increase gonadotropin secretion and activate the hypothalamic-pituitary-gonadal axis. It has been explored in fertility research and assisted-reproduction settings as a way to trigger endogenous reproductive hormone release.
