Actually, I can't speak to this specific brand compared to others, but I can speak to Quercetin. The research is incredibly strong about the benefits of Quercetin and flavonoids. A few decades ago, in college I liked to hang out in the medical library to try to figure out what the research was saying. Back then, the research was starting to cover antioxidants, blood sugar and other topics that didn't enter public awareness for another couple of decades. Some studies started covering bioflavonoids, though the only thing I could figure out was that you could get them from the white part of citrus fruits. Now there is a vast literature exploding about the benefits of flavonoids on what seems like every dimension related to health, including telomeres, which predict life expectancy. And my impression is that there seems to be hundreds of journals now dedicated to flavonoids alone. I am saying all this because Quercetin is a flavonoid and I can't think of any other compounds that are actual flavonoids Back when I was hanging out in the medical libraries, I concluded that the basis of health disorders was blood sugar. At this point, the research seems pretty clear, the most obvious basis for health disorders is inflammation. Inflammation has adverse effects on blood sugar levels, hence the original findings. Quercetin and flavonoids are among the products (what do I call these?) that reduce inflammation and associated with a host of benefits in health disorders. But the vast literature that is coming out about Quercetin (among other products) makes it clear that it's an important one.

I can't say enough about this product. A friend who works in the Wellness section of a grocery store told me about Quercetin. She said her relative would get sinus infections from mowing the lawn. I have seasonal allergies, OTC products were not working and although I take Benadryl it doesn't prevent infections. I get sinus congestion and congestion in my ears that reduce my hearing, along with bronchitis and asthma. I began taking Quercetin and I am a committed fan!!! I've been taking it for about a year and a half. I haven't had 1 sinus infection since I began taking it. Also, after the first week taking Quercetin my ears popped! No sinus infections means no respiratory infections! I'm delighted! I have severe food allergies where even 1 bite of pizza crust (wheat) or 1 Hershey's kiss (chocolate) can result in a sinus infection within a couple of weeks. With Quercetin I can eat chocolate again if I'm careful! I can also enjoy a piece of bread once or twice a year. Even if my ears get congested they will pop again. This product has given me a wonderful freedom I didn't have beforel

I ordered this product because University of Arizona School of Integrative Medicine and also Eastern Virginia School of Medicine recommended it as part of a possible prophylactic for Covid, and I recommended it to friends and family. Several have reported that their allergy symptoms have lessened, they were able to cut back on their allergy medication, and in one case even use their inhaler less frequently. Also, my 85-year-old Mom's blood tests came back last week showing a significant decrease an inflammation. When I told her doctor what she's been taking since March she said it was "probably the Quercetin." I am happy with this brand.

I had burning watery eyes, constantly running nose, and sneezing from cat allergy, but of course I have a cat and will always have a cat or two. At first I tried OTC antihistamines which made me sleepy and then went to the doctor for prescription allergy drugs. They did not work at all. Finally I tried this and my problem is over. I take twice per day. I would have to take 3 times per day if I let my cat into the bedroom at night, but I keep the bedroom as a cat free zone. This is an effective economical brand that does not contain bromelain. I found that bromelain makes me more susceptible to bleeding into my forearms and gums, so I avoid it.REVISION: Used this brand for years. Received 2 new bottles and noticed I was sneezing and nose running all day long. This went on for 2 days until I thought, "Is it the quercetin?" I tried capsules from the second bottle. Same problem. My husband was taking Jarrow brand quercetin. I tried it and it stopped the sneezing and nose running within an hour. I have opened both bottles and can't return as it was a gift. Something bad has happened with this brand that used to be good. This revised rating (from 4 to 1) is about capsules received February 2023.

This is one of the variety of supplements my wife and I regularly take.

This is great for seasonal allergies and overall wellness.

It helped us hve an easier time with c-19. My entire family took it while my husband and I were sick in December.

great product from a company I trust
