Effects on oral fat load of a nutraceutical combination of fermented red rice, sterol esters and stanols, curcumin, and olive polyphenols: A randomized, placebo controlled trial

Abstract Background In literature, there are several studies about the effects of nutraceutical combinations at fasting, but data in post-prandial phase are lacking. Purpose We planned a study to evaluate the efficacy and safety of a nutraceutical agent containing fermented red rice, phytosterols and olive polyphenols compared to placebo in a sample of Caucasian patients with low cardiovascular risk, both at fasting and after an oral fat load. Study design Eighty patients were randomized to receive, as addition to diet and physical activity, a nutraceutical combination containing fermented red rice, sterol esters and stanols, curcumin, and olive polyphenols or placebo (control group), once a day. Methods We evaluated at baseline, and after 3 months: body mass index, fasting plasma glucose, lipid profile, soluble intercellular adhesion molecule-1, soluble vascular cell adhesion molecule-1, and soluble endothelial-leukocyte adhesion molecule-1. We evaluated these parameters both at fasting, and after an oral fat load. Results Nutraceutical combination gave a reduction of total cholesterol, triglycerides, and low-density lipoprotein cholesterol, both compared to baseline ( p p p p Conclusions The nutraceutical combination of fermented red rice, sterol esters and stanols, curcumin, and olive polyphenols seems to be effective in improving lipid profile and markers of endothelial damage in dyslipidemic patients in primary prevention at low risk for developing cardiovascular disease. The true novelty of this study, however, is the improvement of endothelial damage after an oral fat load compared to placebo.
