iHerb Customer Reviews

Synthetic vitamin E used!

Posted by Jodi-Hummingbird on Jul 28, 2014

I'm so annoyed I bought this and didn't notice until later that the synthetic DL form of vitamin E is used in this product. A brand like Nutricology really should know better than to use such an inferior and problematic form of vitamin E.

Review of Quercetin

I have found this product to be useful in combating my hayfever, which I have through out the year, but especially in Spring.

great product, no nasty excipients

Posted by JasonArgo on Oct 24, 2013

Quercetin works fine for my rash and hay fever, but this is the only one found at iHerb without those nasty excipients, such as stearates.
