Abstract
Abstract Aims Nutraceuticals are dietary supplements that contain a concentrated form of a presumed bioactive substance originally derived from a food. There is a relationship between the consumption of monacolin K from red yeast rice and maintenance of normal blood low density lipoprotein cholesterol (LDL-C) concentrations recognized by the European Agency on Food Safety. The present study evaluates the effects of a therapeutical association of nutraceuticals (a combination of containing fermented red rice, named Monacolin K and Coenzyme Q10) on lipo-glycaemic profile and on the vascular function evaluated as endothelial function and arterial stiffness (using the non-invasive methods of EndoPAT and SphygmoCOR). Methods The present is a single-centre prospective study enrolling 30 patients with low cardiovascular risk profile (SCORE risk, cardiovascular disease risk <10% at 10 years). Patients were consecutive enrolled from March 2019 to February 2020 (recruitment period). The average follow-up was 14 weeks, from intaking monacolin K 10 mg + Coenzyme Q10 10 mg. The scheduled evaluations of the enrolled population were: before the beginning of the therapy and after a period of 14 weeks. Results After 14 weeks of treatment we demonstrated a statistically significant reduction in total cholesterol (P 0.015) and LDL (P 0.003). An important effect on the inflammatory profile was highlighted, resulting in a decrease in Hs-CRP at 12-weeks (P 0.052), associated with a progressive reduction of arterial stiffness (P 0.063) and an improvement in endothelial function (P 0.048). Conclusions Data obtained suggest that formulations with natural nutraceuticals, especially fermented red rice, have a protective cardiovascular effect, not also through reduction of plasma lipids but in endothelial function and arterial stiffness improvement.
