FRS: Powdered Drink Mix

An independent, randomized, double-blind, placebo-controlled, cross-over study suggested that when 12 healthy, active (but not highly trained) men and women consumed 500 mg of quercetin (QU995™) in an enriched drink mix twice daily for 7 days, they experienced an increase in endurance and in VO2max (a typical measure of fitness). The study has been published online in the International Journal of Sports Nutrition and Exercise Metabolism.

An independent, double-blind, placebo - controlled crossover study on the effect of FRS on cycling performance in eleven elite cyclists was completed at Pepperdine University and published in the International Journal of Sports Nutrition and Exercise Metabolism. The results were dramatic: an increase in performance - one minute and 31 seconds improvement in time to complete a 30km simulated mountainous time trial.

A clinical study, funded in part by the United States Defense Advanced Research Projects Agency (DARPA) suggested the antioxidant quercetin significantly reduced incidence of upper respiratory tract issues during the two week period following intensified exercise. Researchers also reported enhanced alertness and reaction time in athletes taking the quercetin supplement during high stress. Forty test subjects were subjected to extreme physical stress during a five week period. Half were given 1,000 mg of quercetin daily (the approximate amount in 3 servings of FRS) and half were given a placebo. Results showed:

During a six-week study, university employees were asked to perform their daily jobs, which required physical exertion, lifting, repetitive movements and attention to detail. At the end of the study, subjects experienced improvements in various measures of work performance, as measured in a Work Productivity Assessment Index survey.
