In mouse models of insulin resistance, it significantly inhibits NNMT activity in liver and muscle, reduces NAM methylation, increases intracellular NAD+, activates the SIRT1 pathway, promotes phosphorylation of insulin receptor substrate 1 (IRS1), enhances insulin signaling, improves insulin sensitivity, and increases glucose uptake and utilization

Peptides like Epitalon may offer a targeted immune recalibration, especially for aging or immunocompromised individuals

The study showed both time-dependent and dose-dependent increases at mRNA and protein levels

The peptide mobilizes fatty acids from storage, and exercise provides the metabolic demand to oxidize those fatty acids for energy, potentially creating a synergistic effect
