Not the most effective quercetin by any means

Posted by 5314020378583434866 on May 30, 2013

This product is nowhere near as effective as the Life Extension Optimized Quercetin. I can hardly notice that I've taken anything with these Twinlabs capsules yet the Life Extension quercetin has a noticable effect from the very first capsule.

Excellent product

Posted by Reviewer1876199 on Jan 26, 2012

Best thing to take for allergies and colds, much better than antihistamines, and just as effective for me. Only problem with this is the weight of the glass bottle increases delivery costs.

too big for kids

Posted by Reviewer1848502 on Sep 14, 2011

i was hoping that my daughter could take this to improve her health, but the pills were too large for 7 yrs old to swallow. when i broke up the capsules to mix in a drink for her, it tasted very sour. She just hated it.
