The present application relates to an anti-aging composition for improving cardiovascular function and a preparation method and application thereof, and the composition comprises L-
ergothioneine,
honokiol,
quercetin and coenzyme Q10. The present application creatively designs an anti-aging composition for improving cardiovascular aging, which improves cardiovascular aging from four dimensions of "myocardial
energy supply + anti-hypertrophy + endothelial protection + anti-oxidation". Coenzyme Q10 can restore myocardial mitochondrial
ATP production,
honokiol can reverse
myocardial hypertrophy through NAD+ deacetylase,
quercetin can improve endothelial function and reduce
blood pressure, and L-
ergothioneine can protect vascular endothelial cells from
oxidative damage and inhibit the formation of ox-LDL. Through research, it is found that the four can cooperate and synergize with each other, and can jointly play an excellent role in improving cardiovascular aging, and achieve multiple protection for cardiovascular aging.
