The lack of harmonized global regulatory standards for purity, dosage, and health claims further complicates translational applicability
Interplay between GLP-1 Signaling and Muscle Metabolism GLP-1RAs modulate metabolism through multiple intracellular signaling pathways, including cAMP/PKA, PI3K/Akt, and SIRT1-mediated cascades, influencing glucose uptake, mitochondrial function, and inflammatory responses [82], which may contribute to interactions between GLP-1RA therapy and skeletal muscle metabolism, potentially affecting muscle metabolism and quality
