Outcome Measures

Primary Outcomes (1)

  • Level of plasma endotoxin (plasma levels of lipopolysaccharides) in the volunteers before and after the 12 week intervention

    Quantitative, kinetic assay for the detection of gram negative bacterial endotoxin (lipopolysaccharide) is used to test whether the probiotic intervention can reduce plasma endotoxin levels (IU/ml) compared to the baseline.

    12 weeks

Secondary Outcomes (8)

  • Volunteer weight before and after the 12 week intervention.

    12 weeks

  • Volunteer waist perimeter before and after the 12 week intervention

    12 weeks

  • Insulin resistance (HOMA-IR index), glycemia, insulinemia and glycated hemoglobin in the volunteers before and after the 12 week intervention

    12 weeks

  • Brachial blood pressure of the volunteers before and after the 12 week intervention.

    12 weeks

  • Blood lipids in the volunteers before and after the 12 week intervention.

    12 weeks

  • +3 more secondary outcomes
