About this study

Prospective, parallel, randomized and double-blind clinical-nutritional study of 8 weeks of duration and 2 study groups (1) Food supplement with extracts of the fungus Shiitake; 2) Placebo supplement with maltodextrin) to evaluate the effect of a food supplement derived from the Shiitake mushroom (Lentinula edodes) on the lipid profile, other cardiovascular risk factors and the intestinal microbiota in subjects with hyperlipidemia moderate without pharmacological treatment.
