FRS: Liquid Concentrate

FRS's revolutionary blend of nutrients extends your body's natural energy, fueling you up when you need it while supporting your health over the long haul.* There's no jittery feeling or roller-coaster ride - just prolonged energy that helps keep you focused and fully charged.*

That energy comes from our secret weapon, quercetin, an antioxidant found in foods like blueberries, apples and grapes.* Its incredible ability to support your body's energy system is what keeps you feeling energized longer.* Add a host of essential vitamins and you're ready to tackle anything from minor workouts to a major marathon.*

A single 11.5-ounce serving of FRS contains a healthy amount of quercetin, but one you'd have a hard time getting on your own; that is, unless you have a tendency to eat 40 apples in a single sitting.

Endurance and VO2max Study:
Davis, Carlstedt et al. 2009
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.

Sports Performance Study:
MacRae, H. and Mefferd, K. 2006
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.*

Immune System Study:
Neiman, David, Henson, DA, et al. 2007
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:

Work Performance Study:
Durak, E. and Bell, M. May 2005
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.*
