Quercetin is a bioflavonoid that supports cellular health and function. In human cell culture studies, it has been shown to block the manufacture and release of inflammation-causing substances, which can help support a healthy immune response to the seasonally changing environment. It also helps promote a healthy cardiovascular system by preserving endothelial integrity and supporting healthy blood glucose levels for those already within normal range. Optimized Quercetin is a proprietary formulation that sets the "gold standard" for high-quality quercetin derived from a food-source blend.

iHerb Customer Reviews
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.
So Disappointed...not for weight loss

Maybe this is only for allergies. But I read several articles and reports that this product along with Resveratrol (which I also bought) would help with losing weight, since it tricks the body into thinking it is calorie deficient. But nothing...nada. I have taken it for about 4 weeks religiously. About 2,000 mg a day as per the information I read. So if you are wanting it for weight loss - I would forget it.

Additional Respiratory Relief
Posted by Reviewer1548715 on Aug 07, 2015
After a significant sinus infection that was brought under control using IP6 and NAC, I'm using this to help rid my respiratory tract of any lingering sticky mucus that coughing can't dislodge. It takes experience to know what to use when and for how long.

I'll order this item again. This product is very good.
The best quercetin product I have tried
Posted by 5314020378583434866 on May 30, 2013
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!
