Effects of 10 mg Monacolins on Vascular Health: a Clinical Trial


This will be a double-blind randomized clinical trial carried out on subjects with suboptimal control of LDL-cholesterolemia, following a Mediterranean diet, and treated with a red yeast rice extract (containing 10 mg monacolin K per daily dose) or placebo, in order to evaluate the middle-term effects on vascular health evaluated by non invasive methods (Vicorder(R) apparatus)
