In addition, carnitine supplementation increased contracture of the heart shortly after reperfusion
It is studied in research into body weight regulation, fat metabolism, appetite regulation and glucose metabolism, thanks to its activity at the GLP-1, GIP and glucagon receptor
Polymorphisms in the GLP1R gene affect receptor function and have been associated with differences in glucose metabolism, body weight, and response to GLP-1 medications
Studies indicate no harmful interactions between these medications once they enter the bloodstream

Mel is a pineal hormone with lipophilic properties, allowing it to easily cross cell membranes and exert antioxidant effects through both direct and indirect mechanisms.39 Previous studies have reported that melatonin not only scavenges ROS directly but also enhances the expression of antioxidant enzymes such as SOD, CAT, and GSH-Px, thereby providing indirect antioxidant defense.17,40 Melatonin is an indoleamine with notable antioxidant properties, making it a promising agent to counteract inflammatory and neoplastic processes and to manage transplantation outcomes.18,41 However, despite strong evidence from animal studies supporting its antioxidant mechanisms, the clinical applications of melatonin in reproductive medicine are still quite limited in the literature.18,19 Similarly, GSH is an endogenous antioxidant capable of neutralizing free radicals and supporting the GSH-dependent peroxidase system
