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. Magnesium ascorbate is a buffered (non-acidic) form of vitamin C that helps support the immune system.

Helps with allergies such as hayfever

Posted by reflexheather on Jan 29, 2014

Helps my partners sinus problems. less sneezing etc. Quercetin is a natural anti histamine and works well when taken with B vitamins for hay fever. I have worked for two of Dublin’s top health stores for 10 years and am now a holistic practitioner. I hope you found this review helpful.

Seemed to help

Posted by healthydoesit on Oct 10, 2013

My dad was hesitant to take this "natural stuff," but ended up being satisfied with the results. He claims he's not sure if it worked or if he just got better. Haha. But he felt better each time he took.one. I will purchase more for him. He had no drowsiness like he would with otc allergy meds. Take a look at my page to see over 100 real reviews from products I've purchased and tested here at Iherb!

Didn't notice anything

Took these with some other supplements. Didn't notice anything unusual, but at least I didn't have any negative effects. Got these as a sample.
