INTRODUCTION: The scientific community and consumers are increasingly interested in the potential cholesterol-lowering effect of various nutraceuticals and their combinations. The aim of our study was to test the short-term effect of a new lipid-lowering nutraceutical formulation in mildly hypercholesterolemic patients.
MATERIAL AND METHODS: We consecutively enrolled 80 mildly hypercholesterolemic patients with low-density lipoprotein-cholesterol (LDL-C) between 130 and 190 mg/dl with a low-estimated cardiovascular disease risk. After a 8 week-stabilization diet, the enrolled subjects were randomized to take 1 pill/evening of Zeta Colest (including: 400 mg of Berberis aristata dry extract with 340 mg of berberine, 98 mg of red yeast rice extract with 2.9 mg of total monacolins, 87.5 mg of milk thistle dry extract with 70 mg of silymarin, 50 mg of guggul dry extract with 1.3 mg of guggulsterones) or placebo for 8 weeks. Patients were followed up for metabolic and haemodynamic parameters.
RESULTS: After 8 week-supplementation with the tested combined nutraceuticals, we observed a significant reduction in total cholesterol (-15.2 ±1.4%), LDL-C (-18.1 ±1.9%), non-high-density lipoprotein cholesterol (-17.7 ±1.8%), apoB (-16.9 ±1.9%) and high-sensitivity C-reactive protein (-3.7 ±0.7%), versus both baseline (p < 0.05) and the control group (p < 0.05). No other metabolic or liver parameters significantly changed during the observation period. Endothelial reactivity also mildly but significantly improved by 2.96 ±0.23% with the tested product.
CONCLUSIONS: In the short term, the tested combined nutraceutical improved lipid metabolism, systemic inflammation and vascular function in mildly hypercholesterolemic overweight subjects.
