Health journalist Bill Sardi takes this product!

Posted by iHerb Customer on Oct 04, 2008 | Verified Purchase

So far, so good. Works as a natural anti-histamine, and to me, the Vitamin C in this form doesn't seem as acid as in an ordinary pill. You can find more about Quercetin via Bill's or Google "Bill Sardi Archives" without the ". Or just search "Quercetin".

Natrol won't reply to my query

Posted by emanuela on Mar 09, 2014 | Verified Purchase

I have written to Natrol twice asking whether this product contains GMO (for instance, the vitamin C part). No reply yet. I am suspicious of companies that do not take the time to reply to customer queries.

Thanks for your feedback!

natrol quercetin 500mg

Posted by iHerb Customer on Apr 14, 2013 | Verified Purchase

I actually bought this for myself, but it was the result my husband got that sold me. He was having an allergy related asthma attack and the rescue inhaler was not lasting the full 4hours. He was wheezing and coughing and could not stop. I gave him natrol quercetin and within 15 minutes his recovery was amazing. His wheezing subsided alot. No drowsy side effects... This product is a life safer.

Thanks for your feedback!

I have noticed that I have not woken up with such a stuffy nose since taking this. I also take Nettle & Butterbur for extra relief.

My doctor suggested I take this about 4 years ago. I was not seeing or feeling any results and would go off of it. I did this 3 times and w/in a few weeks I would get sick and b/c my asthma was so bad, I'd end up in the hospital. I went back on and have not missed a dose in over a year. I have gone through two cold/flu seasons and all the illnesses my kids bring home w/o getting sick or having problems w/ my asthma. This stuff is amazing!

This is a fabulous product I have been taking for years. It helps with seasonal allergies and joint flexibility. I prefer tne Natrol brand as I have tried others that are derived from other sources and had a bead reaction. Also gives me some C.
