Have been using for a number of years.. I use it as a natural remedy for my allergies (runny nose).. Does the job.. Btw make sure you take 2 pills for the 500mg.. 1 pill is equal to 250mg of quercetin.

Thanks for your feedback!

Tried taking it for IC - no effect

As a sufferer of Interstitial Cystitis (amongst other things) I tried this Quercetin formulation as directed and experienced no effect (aside from mild heartburn).

Thanks for your feedback!
