Effect of Totum-070 on Lipid Metabolism in Moderate Hypercholesterolemic Subjects (HEART)

Randomized Placebo-controlled Double-blinded Study of the Effect of TOTUM-070 on Lipid Metabolism in Moderate Hypercholesterolemic Subjects

This clinical study aims to assess the efficacy of TOTUM-070, a mix of 5 plant extracts, on lipid metabolism in moderate hypercholesterolemic subjects. The hypothesis is that TOTUM-070, daily consumed, is superior to placebo for decrease of fasting blood LDL-cholesterol concentration (determined by ultracentrifugation method) after 24 weeks of consumption.
