Health journalist Bill Sardi takes this product!

Posted by Reviewer1355153 on Oct 04, 2008

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 TheCancerbook.com 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

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.

natrol quercetin 500mg

Posted by Reviewer1176499 on Apr 14, 2013

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.

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.
