Evaluation of SODB® in Metabolic Adaptations in Overweight Women (SORESCAL)

Evaluation of SODB®, Associated With a Caloric Restriction, in Metabolic Adaptations in Overweight Women: Randomized Double-blind Study Versus Placebo

The objective of this study is to evaluate the influence of a 3 months SODB® supplementation in adipose tissue modulations of overweight women, in comparison to a placebo.

Study Overview

• Status: Unknown
• Conditions: Overweight
• Intervention / Treatment: Dietary supplement: SODB Dimpless; Other: caloric restriction; Dietary supplement: Placebo

Detailed Description

Beneficial experimental results have already been obtained with SODB®. That is why, the investigators expect several effects of SODB® here. Indeed, this clinical study could show that SODB® is able to induce endogenous antioxidant defence, and then reduce oxidative stress generally observed in overweight adipose tissue.

Moreover, this study could evaluate the impact of a decrease in oxidative stress on the others overweight-induced disorders, such as insulin resistance, inflammation, fibrosis, lipolyse alterations.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: SODB Dimpless-caloric restriction; This arm receives daily two capsules of SODB Dimpless 40mg containing 480 UI of superoxide dismutase (SOD), associated with a moderate caloric restriction.	Dietary supplement: SODB Dimpless; Subjects are supplemented with SODB, daily over 3 Months. Each volunteer was seen for the 4 visits: - visit of pre-inclusion, - visit V1, so-called inclusion visit, - visit V2 at 1,5 months and - visit V3 at 3 months; Other: caloric restriction; Caloric recommendation reduced by 20%
Placebo Comparator: Placebo-caloric restriction; This arm receives daily two capsules Placebo containing excipients only, associated with a moderate caloric restriction.	Other: caloric restriction; Caloric recommendation reduced by 20%; Dietary supplement: Placebo; Subjects are supplemented with placebo, daily over 3 Months. Each volunteer was seen for the 4 visits: - visit of pre-inclusion, - visit V1, so-called inclusion visit, - visit V2 at 1,5 months and - visit V3 at 3 months
