Effective Natural antihistamine
I have used this products for quite a few months now and I will say it has been a game changer for me. I used to have ear drainage a lot throughout the year and get ear infections multiple times a year and now my ear problems have stopped. If you’re looking for an effective and natural antihistamine this is it! I’ll continue taking this product as it has been very helpful for me. 100/10 recommend!

Goodbye OTC antihistamines & all their side effects!!!
I can't praise Quercetin Complex enough!!! My allergies were so bad (allergic to everything except dogs and cockroaches - really). I was on weekly shots (for years), citrizine in the morning, fexofenadine at lunch (loratadine had no effect), 3-4 times the normal dose of budesonide nasal, azelastine as needed, as well as daily guaifenesin and pseudoephedrine, plus Budesonide/formoterol inhaler for the chronic cough, and albuterol in a nebulizer. I was still miserable. Post nasal drip, constant throat clearing, sinus headaches & migraines, chronic rhinitis and frequent bronchitis. Then, the doc said I had GERD. I started reading about side effects and guess what? The OTC antihistamines CAUSE chronic cough and GERD. The omeprazole the doc wanted to put me on also has side effects - all the acid-reducing meds do. They block protein absorption which seriously limits your body's ability to heal. To top it all off, the main symptom of GERD is too LITTLE stomach acid - not too much. Adding 2 Tbsp of organic, non-GMO apple cider vinegar to my tea has helped immensely. Most docs just treat symptoms, none try to find the cause. The cause was all the pharmaceuticals they kept putting me on. Each one to treat the side effect of the last. ENOUGH! I found Quercetin when the doc put me on omeprazole. It made me sick, so I started researching. It took a few weeks for Quercetin to kick in fully, but now, I'm off all the OTC antihistamines, only use budesonide nasal occasionally, haven't touched azelastine, only use Budesonide/formoterol inhaler twice a day instead of 4x, only need the nebulizer if I get sick, and am looking for natural alternatives to the guaifenesin and pseudoephedrine. It also helps to add Similisan nasal allergy relief spray and Similisan allergy eye drops. Both are natural and don't have side effects. Now, my headaches are better, fewer migraines, less post nasal drip, less coughing, less allergies. I feel so much better! The docs and the pharmaceuticals were only making me worse. I live in Florida and I would have migraines at least a week before through a week after every hurricane that came within a few hundred miles of here because of all the pressure changes. My head is a human barometer. Every change triggers a headache and I have to hold my nose and blow like on an airplane whenever the pressure changes. When hurricane Irma came through, I had a migraine for 4 weeks!!!! This year (w/ Quercetin) we had one come close and I just had to clear my ears a few times - no hurricane migraine for the first time since we moved down here (15 yrs)!!! I can't believe the difference!!! Thank you Solgar for making this amazing product!

Exciting research is happening with quercetin. I'm willing to try it.
I bought several bottles of this because I've been reading about the Covid19 trials that will be happening in China with quercetin. Researchers at the Clinical Research Institute of Montreal (IRCM) believe that quercetin is a “broad spectrum” antiviral drug that could fight a range of viruses. The clinical trials in China will involve oral supplements taken four times a day with infected patients. The clinical trials have not happened yet, but it sounds promising and this supplement has few side effects. So, I'm taking a chance and having a few bottles on hand in case anyone in my family gets sick. It's also a bonus that this manufacturer includes Ester-C which is also good for immune support.

Amazing, helps me feel "bright"
I have purchased like 25 bottles over 5 years, I don't have any issues with bleeding like that one reviewer. I was having huge seasonal allergies and dust and food allergy -this has zero side effects, no drowsiness, and honestly after a few years of taking either 2-4 a day in the summer and spring or 2 a day in the fall (helps a lot with stuffy indoor dusty areas), I honestly don't even have allergies anymore. I probably acclimated, but my dad who has lived here for 25 years still has allergies and he pumps his head full of Flonase and whatnot. I love solgar and am thankful for this. I get one cold every 18 months or so, big improvement from before where I was getting sick every couple months, but it should be noted I also transitioned to a fully Autoimmune Paleo diet (it matched my food allergies and the nurse recommended) and Took Bluebonnet chelated Multimineral to help reverse years of malnutrition and celiac. Check with your doctor but these things combined were powerful and my white blood cells are in the healthy range again (including neutrophils). Another thing is that I would take these with solgar iron biglyscinate (very dangerous unless you've gotten your levels tested and proven to be low, but many women have menses and low iron intake so it made sense I was almost anemic). It really activates it with the vitamin c. Thank God for solgar basically healing my body along with my change in diet

Suffered from asthma, sinus and allergies lifelong and I do work with dogs daily for the past 13 years (sometimes I wonder why but love these furry friends too much) and the shedding and fur triggers my allergies and asthma. It became worse after I hit my 50s and I was hospitalised and treated with nebuliser. Ventolin, steroids and Zyrtec were prescribed but came with side effects plus the dosage kept increasing. Tried TCM which worked but was super expensive as nearly $750 a month was not sustainable in the long run. Book: I was praying and the Lord led me to a book by Raymond Francis which mentioned Quercetin for allergies/asthma/sinus. I had nothing to lose so I ordered it on Amazon. Quercetin: Started taking it like 3 times a day along with Vitamin C but there were no visible results at the start. I still had to use my inhaler and woke up several times a night wheezing and unable to breathe as asthma attacks continued. Around week 4, things started to look better as there was a noticeable improvement and for the first time in many many months I could sleep through the night. Now I hardly have to use my ventolin inhaler and my asthma/allergies are under control though my right nose is still partially blocked which I know by God's grace will be healed soon. So if you suffer from asthma, sinus or allergies give this a try but don't expect instantaneous results. I pray for healing of sinus, asthma and allergy issues for everyone reading this review who is going through this ordeal. I know how difficult it is... Amen!
