The principle of GreFits ULTRA capsules is based on using natural plant-based ingredients that stimulate the body to naturally release inosine.
This activates surrounding healthy brown fat cells, enhances their heat production, accelerates fat burning, and supports weight loss.
This theory is rooted in the research paper "Apoptotic brown adipocytes enhance energy expenditure via extracellular inosine" by Birte Niemann and Alexander Pfeifer, published in the journal Nature. It details how inosine works through the activation of brown adipose tissue to combat obesity.
GreFits ULTRA enhances the activity of brown fat tissue and counteracts diet-induced obesity.
