Pantethine is an important component of coenzyme A, and coenzyme A is the central link of lipid metabolism and sugar metabolism. Pantethine improves serum lipid levels by promoting fatty acid β oxidation and inhibiting HMG-CoA reductase activity, effectively reducing TG, TC, LDL-C, and increasing HDL-C.
