[57] It suppresses appetite through a dual mechanism: it directly stimulates anorexigenic (satiety-inducing) neurons that express proopiomelanocortin (POMC) and cocaine-and amphetamine-regulated transcript (CART), while simultaneously inhibiting orexigenic (appetite-inducing) neurons that express AgRP and NPY
It appears to enhance the expression of growth factors like VEGF (vascular endothelial growth factor) , support nitric oxide pathways for improved circulation, and reduce pro-inflammatory markersall without disrupting normal healing responses
