  Purpose

Nutrasorb is a newly developed food product (see www.nutrasorb.com). This study will use the Nutrasorb soy protein product that is matrixed with polyphenols from blueberries and green tea extract, and test for efficacy as a nutritional countermeasure to exercise-induced physiologic stress (i.e., immune dysfunction, inflammation, and oxidative stress) using both traditional and metabolomics-based outcome measures.

Primary Outcome Measures:
  • Metabolomics; change in metabolites over time [ Time Frame: 18-day period; Blood samples collected pre- and post-14 d supplementation, and immediately and 14 h after the third day of running ] [ Designated as safety issue: No ]
    GC-MS and LC-MS through Metabolon


Secondary Outcome Measures:
  • Change in inflammation [ Time Frame: 18-day period; Blood samples collected pre- and post-14 d supplementation, and immediately and 14 h after the third day of running ] [ Designated as safety issue: No ]
    CRP and a cytokine panel

  • Change in oxidative stress [ Time Frame: 18-day period; Blood samples collected pre- and post-14 d supplementation, and immediately and 14 h after the third day of running ] [ Designated as safety issue: No ]
    F2-isoprostanes, protein carbonyls, FRAP, ORAC

  • Change in immune function [ Time Frame: 18-day period; Blood samples collected pre- and post-14 d supplementation, and immediately and 14 h after the third day of running ] [ Designated as safety issue: No ]
    Anti-viral activity using virus-infected HeLa cells
