This quercetin is very good for allergies. I can tell the difference between this product and other brands. I take two twice a day in order to get 500mg twice a day. With another brand, 1000mg twice a day was comparable, and with another brand I had to take 500mg three times a day for same effect. Life Extension has not dissapointed me yet.

I have a dog with food sensitivities. I have read that quercetin can alleviate the symptoms by inhibiting histamine release. I have tried several brands, but the improvement was minor. The reviews for the LE brand claim that it is superior to all others. In general, I am sceptical of such reviews, but I took a chance. I am glad I did. Not only is it better than other brands of quercetin, it is a lot more effective than Histame (at least in the case of my dog). Thank you, LEF.
The best quercetin product I have tried

This is fantastic for clearing my stuffy sinuses, it starts working within 20 minutes of taking it. The dose is just right for me, one tablet a day and possibly another in the evening if my allergies are really bad. I have tried lots of other brands but this one just works!

Life Extension is a very good company and I trust their products completely. Helps my allergies and also good for blood pressure if you take enough of it. I take one to two caps a day.
Respiratory Relief, AND A REMARKABLE DISCOVERY!

I used Quercetin to successfully help with a sinus infection. IN ADDITION, and in combination with Nature's Answer Resveratrol, discovered they have a strong anti-proliferate effect on CLL (chronic lymphocytic leukemia) in this body: Every four months, my CBC shows a noteworthy decline in WBC! My hematologist is stunned. He asked for a list of supplements I use. RSV and Quercetin are at the top. Best wishes to everyone for good heath, Ernest - NYC
Helps my allergies

The shipping was very fast. I got relief from my allergies without the side effects of other allergy meds. I have very severe seasonal allergies so some days I still have mild symptoms, but nothing like it would be without the quercetin. Good stuff!
Allergies no more (no symptoms anyway)

Switched from NOW brand (with Bromelain). NOW is a good product, just feel Life Extension is superior. Wanting to simplify my supplements and use only what I need. Testing to see if Bromelain was even/really necessary.
Liking this so far

This seems to help with hay fever symptoms so far but need to take two capsules at a time, maybe twice a day. It is still early days though.
Life Extension, Optimized Quercetin, 250 mg, 60 Capsules

Life Extension needs to put their entire product line in glass bottles instead of cheap plastic containers, include freshness packets, and offer larger count sizes than only sixty measly capsules per bottle.
