I would most likely start with Algonot Plus as I've not been able to find a comprehensive list of ingredients anywhere for any accredited quercetin product (although I may not have looked hard enough). Is there reason to try any accredited quercetin product if Algonot does nothing? If they both contain virtually the same thing, I would assume not.
And finally, are there any risks associated with taking these supplements? I realize everyone is different, but have any side effects been documented? For example, Saw Palemetto can in some cases effect libido and sexual function. Sexual function is absoloutely fine for me right now, and a good sex life with my girlfriend is one of the few things that I can actually enjoy painlessly, I don't want to come across some nasty side-effect which puts a stop to that too
