Neohesperidin is a flavonoid found in citrus fruit peel that has diverse biological activities. In vitro, it inhibits osteoclast differentiation, bone resorption, calcium oscillations, and activation of NF-κB and nuclear factor of activated T cells (NFAT) by receptor activator of NF-κB ligand (RANKL). In vivo, neohesperidin administration protects ovariectomized mice from bone loss. Neohesperidin acts as a hypolipidemic agent, reducing lipid accumulation in HepG2 cells and reversing hyperlipidemia in a mouse model of diet-induced obesity. In a mouse model of diabetes, neohesperidin increases glucose tolerance and decreases insulin resistance while simultaneously decreasing serum triglycerides and total cholesterol and inhibiting lipid accumulation in livers in vivo.
