Helpfulness
Allergies
Dec 29, 2025
This has helped my dog tremendously with allergies. He’s a small dog, 14 lbs and was sneezing his head off. Mucus, and coughing as well. Spent money at the vet to no avail. I got this product and it’s worked wonders. He’s an older dog at 16 with CHF, and I think this helps as well with his overall health. Wasted money at the vet. I would recommend dosing the powder throughout the day as giving at one meal upset his stomach. But great price and great product. Thanks Dr Jones!
Only thing that works!

At 94 lbs, my rottweiler was skin and bones. He was tested for allergies and the list was long, including being allergic to our cat, certain trees and grasses and many foods. The foods we can avoid but the environment was more difficult. He was so itchy, sneezy and just miserable! After many rx pills that were crazy expensive and didn't work, I finally found a high quality food, that was not rx and stopped all his pills. He did much better and put on some healthy weight but was still very itchy. After one bottle of Quercetin, he was completely itch free and no more sneezing! He's now a healthy 126 lbs, 11 yrs old and acts like a puppy! He'll be on Quercetin forever! Of course he's also on the liver support formula and probiotics by Dr. Jones and his bloodwork came back much improved. I really like the holistic approach, with natural, high quality ingredients which is how I treat my own body, so why would I treat my beloved dog any different? Thank you Dr Jones!
Amazing
Sep 8, 2025
I have a Shih Tzu & 2 Shorkies. My Shih Tzu 1 of my Shorkies has allergies very bad. I tried all sorts of things. In other words I was at my wits end. They were scratching all the time unless they were sleeping & some time they wake up a scratch. But it was constant. They also had little source on them from the scratching. I felt so bad for them. So I took the jump & purchase this product. Six bottles. After reading so many reviews I was convinced this it. Well I couldn’t believe the results. It was amazing. Before the first bottle was finished my Shih Tzu hardly scratches & she was the worse of the two. My snorkie she still scratches a little but I think in time it will get a lot less. I wish I done this a lot sooner. I could have save them from the misery of it all. If you’re on the fence or have any doubts, don’t. It WORKS!
Shockingly amazing.

I have 2 Great Pyrenees mix, the larger one shed so much that it filled my two robot vaccum cleaners every day. We would joke that we got enough hair from him to make another dog each week. I tried all kinds of supplements but nothing slowed the shedding and itching. So I ordered a month supply of the quercetin. In 3 weeks there is almost no hair around our house. I am totally amazed how well it worked. He's hardly scratching at all.
Thank you Dr. Jones
Great Product!

I’m so grateful for Dr. Andrew Jones and his team! I purchased Ultimate Bio Active Quercetin for my cat’s top lip ulcer, and by day 3 the swelling has already gone down. I have bought the Ultimate Feline Health Formula before, and he absolutely loves it! Their customer service is fast, helpful, and attentive. Thank you, Dr. Jones, for your amazing content and products that keep our fur babies healthy and happy!
No more constant ear infections
Aug 12, 2025
We rescued an American Bulldog 5 years ago, that had constant ear infections. I had to take her to the vet every time, because they were so painful, she would not let me near her ears. I did the allergy shots a few times, that were expensive, not good for her and didn’t work. I can’t tell you how much I spent in vet bills over the past 5 years, ridiculous amount of time and money, for no results. I have had her on the extra strength Quercetin for 2 months now and her ears are perfect! I am so thankful to Dr. Jones for his holistic approach, that actually works. Luna will be 13 years old this month. I’m so happy that she is finally out of pain, living her best life. Many blessings!
