Great for Histamine Intolerance
This supplement is of good quality and helps me tremendously with my histamine intolerance. At the recommendation of my functional medicine doctor, I take it twice a day in addition to ketotifen to help stabilize my mast cells and it works!! I also appreciate that this brand is clean and not full of any fillers that cause me issues as well. I highly recommend it!

Helps MCAS and safe for sensitive nervous system
Helps with MCAS symptoms. I started out with just one at a time.... could feel my nose clear, could breathe, and redness goes down. I had been eating onions to combat the flares-- onions get old. This brand has been a life saver! I am very med sensitive and everything I have tried by Pure Encapsulations has been great for my sensitive nervous system. Highly recommend! Worth the price.

Love the brand and product ♥️
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!

Works for me
My doctor recommended I use these to boost my immune system, and so far no flu or illness since I started.

Works well, maybe too well
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.

My Dr. prescribed this for me
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.
