Review: 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!

I work at a school and this is amazing to keep your immune system strong

### ⭐⭐⭐⭐⭐ Amazing, helps me feel "bright"
*by A***N on August 4, 2021*

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
