In animals it has been demonstrated that Saccharomyces boulardii decrease low-grade inflammation and fat mass; also Superoxide Dismutase (SOD) decrease low-grade inflammation. Therefore, the aim of this double-blind, placebo-controlled clinical trial was to assess the effect of a 60-days S. boulardii and SOD supplementation on circulating markers of inflammation, body composition, hunger sensation, pro/antioxidant ratio, hormonal, lipid profile, glucose, insulin and HOMA-IR, in obese adults (BMI 30-35 kg/m2).
