Detailed description:
Compare an over-the-counter dietary supplement (NutraStem Active®) and placebo over a 30-day intervention on aerobic exercise performance and fatigue.

The hypothesis is that supplementation with NutraStem Active® improve aerobic performance and reduce subjective measures of fatigue.

The basic protocol includes baseline assessment of fitness and participation in a vigorous session of exercise immediately before and 30 days after consumption of the experimental supplement or placebo.

The exercise task is intended to be fatiguing and demanding but is not expected to create failure.

The supplement makes claims related to boosting exercise performance and reducing fatigue.

The study design will determine if these outcomes are in fact present in a group of healthy, young, and active adults.

The primary dependent measures are perceived exertion during exercise and levels of fatigue measured on multiple non-exercise days.

Arms:
arm 1: Daily supplementation with NutraStem Active; 2 capsules per day for 28 days arm 2: Daily supplementation with placebo; 2 capsules per day for 28 days

Interventions: intervention 1: NutraStem Active intervention 2: NutraStem Placebo
