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.

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.
