Quercetin Phytosome 250 mg, 30 VegCaps | 20X Absorption & Antioxidant Support - Easy to Digest Quercetin Phytosome - 30 Servings - Vegan, Soy Free, Lab Verified

32F, live a whole food, clean lifestyle and workout regularly. This is one of my staples for histamine/MCAS and fibromyalgia flares. I can take this on an empty stomach first thing in the morning without issues and within just a couple days, my flare intensity reduces across the board- pain goes down, itchy watery eyes go down, subtle energy returns and my brain comes back online. I take this mostly for physical systemic effects but it’s also helpful for brain support for me as someone who has brain fog from neuroinflammation related to my conditions. For anyone curious or with similar conditions, I think it’s worth noting this acts on histamine by stabilizing mast cells to reduce the release of histamine whereas allergy medications typically block histamine after it has already been released. So may be an excellent add-on to tackle your histamine from more angles, thus reducing not only your histamine load but your body’s total production of histamine as well.

It was suggested I try quercetin for problems with histamine. I have been seeing a difference. It helps a lot.

I had high hopes for this Quercetin supplement. It is a Phytosome form (basically liposomal) and used a patented formula "Quercefit" which has studies showing an absorption increase of 20x over other non-phytosome forms. That said, a supplement can only be as good as all of its ingredients! This includes all the excipients. Unfortunately, this one has a long list — including potato malodextrin. For many, this may not cause issues, but for those with gut issues it can have an additive affect on ibs, ibd, crohn’s and ulcerative colitis. Also, the potato version of malodextrin has been shown to increase any existing traces of e. coli in system. Yes, I did see this additive and decided to purchase it anyway. Since I had not ingested it previously, I did not know it would create mild nausea with increased usage. Live and learn!! So sad, there are so many safer excipients available. I am amazed that a company such as Solaray wouldn't look for the the safest, healthiest excipients to include with their patented "Quercefit"!!! I cannot recommend it based on the poor chemistry. Update: 2/13/26. Seller contacted me based on review and offered a full refund — that is awesome service and shows that Solaray does care about its products and customers. For this, I will give added stars :)

Apparently, this form of quercetin is more easily processed in the body than the other forms. I buy this quite regularly because my system responds to a lot of different foods with inflammation. And that inflammation creates like an internal buzzing in my system. I really noticed it when I’m laying down to sleep and I can feel my system buzzing because of whatever I ate. When I take this, it helps to quell that internal buzzing from my food, turning into inflammation. If you have the same issue as I do, I highly recommend these. The only downside is that with two capsules a day I tend to go through a bottle pretty quickly.

Extremely helpful for my allergies and histamine intolerance. Quite expensive so I can't afford to take them twice daily so I purchased another brand to take for my second dose but it is a really great product. No side effects for me. Just less inflammation and better breathing through my nose.

I.have tried other brands and this one seems to work best for me.

I use these for my allergies and sinuses. It works so well without drying me out like zyrtec does.

Had a very bad intestinal reaction after a few days taking one pill per day. When I wrote a review about this,the seller offered to refund my money since the bottle could not be returned. This was very ethical of them, I appreciated their interest in keeping me as a customer.
