What customers say
Customers are generally satisfied with Solaray's Mega Quercetin, praising its high quality, potent 600 mg dose, and vegetarian-friendly formulation. Many users report significant improvements in managing seasonal allergies and histamine intolerance, noting reduced symptoms like runny nose and blocked sinuses. The supplement is also highly regarded for boosting the immune system, with several customers mentioning they have avoided illness even when others around them were sick. The capsules are easy to swallow and gentle on digestion, though some noted a peculiar smell. While most reviews highlight the product's effectiveness in enhancing overall vitality and physical resilience, a few users experienced adverse effects such as headaches, bloating, and diarrhea. Despite this, the majority find it to be a valuable addition to their daily wellness regimen due to its antioxidant and anti-inflammatory properties.

I decided to try this quercetin supplement for immune and general wellness support. The quality is good, the capsules are easy to swallow, and the ingredients look clean without unnecessary additives. The bottle size is convenient and lasts for a while. Overall, a solid option if you are looking for a reliable quercetin supplement.

Use for allergies
Verified purchase
I use this brand of Quercetin as it is the most absorbable form to consume. My naturopath had me taking another supplement with the dihydrate quercetin then I found this brand. I take one a day all through the year for sinus support. And 2x a day from July to October for allergy season.

Mega Quercetin
Verified purchase
I’ve been taking the Mega Quercetin dietary supplement regularly, and it has quickly become a staple in my daily wellness routine—especially for immune support and allergy relief. Quercetin is a powerful natural antioxidant and anti-inflammatory compound found in plants, and this high-potency formula provides a concentrated dose that has really helped reduce seasonal allergy symptoms like sneezing and sinus pressure.

Solaray, Mega Quercetin
Verified purchase
I have suffered from allergies all my life and wanted to get away from the usual medications that make one drowsy, etc. I discovered Activated Quercetin 15 years ago and have used it ever since with no side effects. It works, not only for pollen but helps with food allergies also.

Helps with mucus
Verified purchase
With so many colds going around you need mega quercetin to help boost your immunity. I also notice it helps with joint pain and inflammation in conjunction with a low FODMAP diet. The quality ingredients benefit the respiratory tract in the body and support healthy lung function. I notice when I don’t take this that I cough more from the dry winter air. I work in a grocery store and this stuff saves me in winter

Solaray, Mega Quercetin, 600 mg, 60 VegCaps
Verified purchase
I like the SOLARY brand quality and 600mg Quercetin content. The capsule is just on the large size (longer than a dime is wide: 7/8 inch long, 1/4 inch wide) for me but I can swallow it ok enough, but I sometimes open the capsule and put it in a "shake". Delivery is always excellent from iHerb. I take 1 a day for anti-inflammatory reasons. I recommend them!

Mega Quercetin, 600 mg
Verified purchase
Mega Quercetin, 600 mg for the past month, and I’m thoroughly impressed with its effectiveness. Quercetin is a powerful antioxidant and anti-inflammatory flavonoid, and I’ve heard a lot about its potential health benefits, including immune system support, reducing inflammation, and helping with seasonal allergies. The capsules are easy to swallow, and I’ve experienced no stomach upset or adverse reactions from taking it.

Mega Quercetin
Verified purchase
The quality of Mega Quercetin is impressive. The supplement features a high-potency formula that contains 600 mg of quercetin per serving, derived from natural sources. Each serving contains 600 mg of quercetin, an antioxidant flavonoid known for its anti-inflammatory and antihistamine properties. I love that this blend targets sinus health specifically, helping to reduce congestion and promote overall wellness.
