About Endogenous Metabolic Modulators

Endogenous metabolic modulators (EMMs) are a broad family of molecules, including amino acids, which fundamentally impact and regulate human metabolism. Our AXA Candidates are comprised of EMMs that individually have a history of safe use as food. We believe that, unlike conventional targeted interventions currently used to address dysregulated metabolism, EMM compositions have the potential to directly and simultaneously modulate multiple metabolic pathways implicated both in complex diseases and overall health.
