Outcome Measures

Primary Outcomes (2)

  • Change in factor nuclear kappaB

    Get blood samples to evaluate the supplementation effects in factor nuclear kappaB by quantitative real-time polymerase chain reaction.

    Baseline and 8 weeks (2 months)

  • Change in intestinal microbiota

    Stool samples will be collected to evaluate the taxa of bacteria colonizing the intestinal microbiota through short-read sequencing of the V4 region of the RNA ribosomal (rRNA) gene on the Illumina platform.

    Baseline and 8 weeks (2 months)

Secondary Outcomes (2)

  • Change in senescence biomarkers

    Baseline and 8 weeks (2 months)

  • Change in uremic toxins

    Baseline and 8 weeks (2 months)

Other Outcomes (2)

  • Change in adhesion molecules

    Baseline and 8 weeks (2 months)

  • Change in blood pressure

    Baseline and 8 weeks (2 months)
