Effects of a Combination of Berberis aristata, Silybum marianum and Monacolin on Lipid Profile in Subjects at Low Cardiovascular Risk; A Double-Blind, Randomized, Placebo-Controlled Trial

Research output: Contribution to journalArticle

Abstract

The aim of this study was to evaluate the efficacy and safety of an anti-hypercholesterolemic agent containing Berberis aristata, Silybum marianum and monacolin K and KA in a sample of Caucasian patients at low cardiovascular risk according to Framingham score. The primary outcome was to evaluate the effects of this nutraceutical combination on lipid profile; the secondary outcome was to evaluate the effect on some inflammatory markers, in particular high sensitivity C-reactive protein and tumor necrosis factor-α interleukin-6. One hundred and forty-three patients were randomized to placebo or Berberol® K, once a day, during the dinner, for 3 months, in a randomized, double-blind, placebo-controlled trial. We recorded a significant reduction of fasting plasma glucose with Berberol® K compared to placebo (-12.2%, p < 0.05). Moreover, we recorded an increase of fasting plasma insulin with Berberol® K both compared to baseline and to placebo (+9.9%, p < 0.05). Accordingly, the homeostasis model assessment (HOMA) index obtained after treatment with Berberol® K was lower than the one in the placebo group (-2.8%, p < 0.05). No variations of lipid profile were observed with placebo, while there was a significant decrease of total cholesterol (-20.5%, p < 0.05), triglycerides (-17.7%, p < 0.05), and low density lipoprotein (LDL) cholestero (-27.8%, p < 0.05) with Berberol® K, compared to placebo. There was a decrease of high sensitivity C-reactive protein (-30.8%, p < 0.05), and interleukin-6 (-25.0%, p < 0.05), with Berberol® K compared to placebo. In conclusion, combining different hypocholesterolemic nutraceutical agents such as Berberis aristata, Silybum marianum and monacolin K and KA could be effective and safe to obtain a reduction of lipid profile and an improvement of inflammatory parameters.
