Introduction: There is a growing interest in nutraceuticals improving cardiovascular risk factor levels and related organ damage.

Methods: This double-blind, placebo-controlled randomized clinical trial aims to compare the effect of a combined nutraceutical containing red yeast rice (10 mg), phytosterols (800 mg), and L-tyrosol (5 mg) on lipid profile, blood pressure, endothelial function, and arterial stiffness in a group of 60 patients with polygenic hypercholesterolemia resistant to Mediterranean diet.

Results: After 8 weeks of treatment, when compared to the placebo group, the active treated patients experienced a more favorable percentage change in total cholesterol (-16.3% vs 9.9%, P < 0.001 always), LDL-C (-23.4% vs -13.2%, P < 0.001 always), and hepatic steatosis index (-2.8%, P < 0.01 vs -1.8%, P < 0.05). Moreover, ALT (-27.7%, P < 0.001), AST (-13.8%, P = 0.004), and serum uric acid (-12.3%, P = 0.005) were reduced by the tested nutraceutical compound both compared to randomization and to placebo, which did not affect these parameters (P < 0.01 for all). Regarding the hemodynamic parameters, there was a decrease of systolic blood pressure (-5.6%) with the active treatment not observed with placebo (P < 0.05 vs baseline and placebo) and endothelial reactivity improved, too (-13.2%, P < 0.001 vs baseline). Consequently, the estimated 10-year cardiovascular risk score improved by 1.19% (SE 0.4%) (P = 0.01) in the nutraceutical-treated patients.

Conclusion: The tested nutraceutical association is able to improve the positive effects of a Mediterranean diet on a large number of CV risk factors and consequently of the estimated CV risk.
