Life Extension Optimized Quercetin 250 mg Supports Immune Health, Heart Health, Non-GMO, Gluten Free - 60 Vegetarian Capsules

My chiropractor told me I must have high histamine because anytime I get hyped up I have red patches on my throat and chest, the quality is great, very effective and the value for the money is amazing. I don’t know if this is helping with pain also but I can say I’ve had to take less ibuprofen

A must have for immune health. Great product

Iv'e tried many brands of Quentin but so far I am liking this one the most. It doesn't upset my stomach and for the price it's nice in quality. I do also like that there isn't any funny smell, I have experienced that in the past with other brands.

Tried this for someone who has allergy brain fog, and they notice an improvement after taking the recommended capsules. Worth the money for solutions!

Works AMAZING to prevent SKIN FLARE-UPS on my dog! I was spending $84/month for Aroquel from my vet. I researched and found Quercetin highly recommended! As directed I weaned my dog SLOWLY off Aroquel. 1/2 tab Aroquel one & 1 250-mg Quercetin followed by a full Aroquel & 1 Quercetin the next. I did this for a full month. Then I started her on a regimen of 1 Quercetin everyday and 1/2 Aroquel every 3 days for 2 weeks, then full time Quercetin only. NO MORE AROQUEL! I’ve also switched to a skin-sensitive salmon-based product that is free of chicken products. It’s been 4 months and NO hot spots, lesions, or rashes!

When opening and inspecting, the aroma indicates fresh herbal ingredients used in manufacture.Product is probably pretty good. Though it is hard to ascertain the long-term effectiveness for what it's reputed to do (they cannot, by law, make medical claims). If it does, indeed, act synergistically with Zinc for boosting the immune response, this is a good one to buy and try out. The "nose knows"!

My doctor told me to take this along with my hormone troche which contains some testosterone that was making my hair fall out. Quercetin helps absorb testosterone without losing hair. It actually worked!

The product description on Amazon when I purchased this indicated “grapes” are an ingredient. The supplement I received does not have grapes. No mention was made in the description of bitter orange or camu-camu, and yet there it is on the label on the back of the bottle. (See the photo I’m submitting) The description should be changed for this product and the supplement facts label included. It might be a great supplement, but it would have been nice to know what was in it before I bought it.
