Randomized, double-blind, parallel study conducted under medical supervision on a group of 40 patients with known hypertension and/or hypercholesterolemia. Patients receive one of the investigational products or placebo for 6 weeks. Before and after the study, the following parameters are analyzed: extended lipid panel (total cholesterol (TC), triglycerides (TG), low-density lipoprotein (LDL), HDL and lipoprotein A, apolipoprotein Apo A1 and Apo B), levels of glucose, insulin, homocysteine, markers of kidney and liver function (alanine aminotransferase (ALT), aspartate aminotransferase (AST), lactate dehydrogenase (LDH), blood urea nitrogen (BUN), uric acid). Effects on blood pressure and anthropometric parameters are also being evaluated.
