Product Overview


  • Dietary Supplement
  • Bioflavonoid Complex

Activated Quercetin is a unique bioflavonoid derived from plant sources. In human cell culture studies, quercetin has been shown to inhibit histamine release. Additional research needs to be conducted to confirm the effects of quercetin, if any, in humans. Bromelain is a pineapple enzyme that may assist the body in times of stress, while vitamin C helps support the immune system.

One of my favorite supplements!

Posted by erichards on Aug 21, 2012

This is a high quality brand that absorbs well, for effective anti-inflammatory relief of symptoms especially seasonal allergies. I take it every day to additionally counteract the effects of less than ideal foods on my system.
