This study aims to demonstrate the effect of the chronic consumption of AB-Life probiotic blend on blood LDL cholesterol level in volunteers with moderate hypercholesterolemia.
1 capsule of AB-Life daily during 12 weeks consumed immediately before, after or during the breakfast. The daily dose corresponds to the intake of 1.8E+10 CFU. According to the product's stability and the duration of the experiment, all participants receive at least 1.2E+09 CFU/capsule/day by the end of the study.
1 capsule of placebo daily during 12 weeks consumed immediately before, after or during the breakfast.
