Animal studies have shown some unique and potentially remarkable effects of quercetin with as little as 7 days of pre-treatment:

  • Increased number of mitochondrial enzymes (muscle & brain)
  • Increased endurance capacity
  • Decreased muscle inflammation (post-exercise)
  • Potential improvement in immune function

 

Objectives of Research:

Development and validation of quercetin assay in plasma & urine for analysis of samples from following studies:

  • Study 1: Quercetin absorption via three oral carrier systems in human subjects (Q Chews, First Strike Bars, Tang);
  • Study 2: Effect of quercetin on maximal oxygen uptake in human subjects;
  • Study 3: Effect of quercetin on exercise performance of human subjects in heat stress;
  • Study 4: Effect of quercetin on muscle soreness in human subjects.
