Jarrow Formulas Quercetin 500 mg
I was asked to review this product by GNC. My order has been on back order for almost a month and I still haven't received it. So I can't let you know about how it's action has been yet.

Quercetin is like endurance in a bottle
I started using quercetin after seeing Lance Armstrong promote its benefits. I noticed an increase in endurance within one week--I went from dragging butt when running 40 flights of stairs to handling 80 flights easily after 7 days. Quercetin is also a strong anti-oxidant. While the human studies on mitochondrial density increase from quercetin are not definitive, I am convinced that it works.
