Brief Summary
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.
