Customers say

Customers find the quercetin supplement effective for allergies and histamine regulation, praising its quality and superior brand reputation. The supplement is easy to take and has no bad reactions, with ingredients that are naturally found in onions. While some customers report no side effects and consider it good value for money, others experience bad stomach pain and find it too expensive.

Love the brand and product ♥️

EmilySeptember 20, 2025

I love and appreciate this brand. Some products have a lot of others ingredients in their pills, but Pure keeps it minimal! Quality is great compared to others I’ve had. My stomach has done well with it. I feel like my immune system is stronger when taking it 💪 Pills are easy to take and I feel like it’s good value for the money! Read more

Solid supplement, but the effects are hard to measure

Michael CollinsNovember 29, 2025

These quercetin capsules are easy to take and the ingredients look clean. Pure Encapsulations usually makes good quality products, and this feels no different. The only thing is that quercetin is one of those supplements where the effects are hard to notice day to day. It is simple to add to a routine if you want extra immune support, but do not expect anything dramatic Read more

Works well, maybe too well

Chris BellJune 30, 2024

I took another brand of quercetin for years, but it doesn't look like that company makes it anymore, so I tried this brand for the first time. It seems to work well, but maybe a little too well when taking a xanthine oxidase inhibitor. I seem to have increased joint pain, which makes me believe it's working to decrease my uric acid along with the allopurinol I'm on. I have dialed back dosing to every other day to see if the symptoms subside. Read more

My Dr. prescribed this for me

J. StancilOctober 18, 2025

Quercetin has many benefits and Pure Encapsulation is a trusted brand. This product is authentic but if you buy a knock off-which will have the same bottle, lot number a total copy in every way it will not contain any of the ingredient it proports to be. You have to do your research! Pattern is the seller of this and other supplement brands on Amazon. To avoid fake knock offs I have called the reputable companies I buy from and they have all cofirmed that Pattern is the only authorized seller of their products. Read more

Great for HIT and MCAS

Happy or NotSeptember 5, 2025

I use Pure Encapsulations Quercetin for immune and antioxidant support, and it’s been beneficial with histamine regulation and mast cell activation issues. Quercetin is known as a natural mast cell stabilizer, which helps calm flare-ups and reduce sensitivity. It also supports cellular and heart health, and the clean, filler-free formula makes it easy to tolerate. Read more
