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.

Suggested Use

3 to 6 capsules daily in divided doses, between meals. If you have a delicate, easily irritated stomach, take with meals.

Other Ingredients

Gelatin (capsule) and magnesium stearate.

Contains no yeast, dairy, egg, gluten, soy or wheat. Contains no sugar, salt, preservatives, or artificial color, flavor or fragrance.


Caution: If you are pregnant, may become pregnant, or breastfeeding, consult your health care professional before using this product.

Activated Quercetin

I have only been using this product for a short time so far but really feel it is doing me some good already. For ages, months, I have been so tired all the time, wanting to sleep every time I stop moving and forcing myself to do things. That has improved and I am getting around better but have a way to go. I have changed nothing else so hoping this is going to help me heaps.

Thanks for your feedback!
