Quercetin belongs to a class of water-soluble plant pigments called flavonoids and can be found in onions, apples, green and black tea. Flavonoids have the ability to neutralise free radicals, converting them to be less reactive compounds therefore reducing their potential to harm cells. Quercetin is actually the most researched bioflavonoid used in human trials and scientists are very excited by its potential benefits to health. One of the most recent studies demonstrated its importance to cardiovascular health, but for more information on this fascinating nutrient, simply search it online. In addition to its antioxidant properties, it is also involved in inhibiting the production and release of histamines.

This is a high strength supplement, which is borne out by the fact that an average apple contains between 5mg and 10mg of quercetin. We use pure quercetin in a form that is easy to absorb.

"Great Result"
By , 24 Oct 2017
Why do you use this product Quercetin ?
I have a condition which results in over sensitivity to a number of foods. I bought Quercetin along with the Bromelain 1000GDU to see if it would help control histamine levels.
Happy to say I have seen a significant drop in histamine reaction since taking these two products together and I will continue to buy them.

"Uric Acid"
By , 24 Oct 2017
Why do you use this product Quercetin ?
I have raised levels of uric acid (which can lead to gout). Studies of quercetin have shown that they block purines from being broken down by xanthine oxidase, which produces uric acid. Purines are found in our diet. Purines are also created through the natural process of cell breakdown in the body. 500mg quercetin is equivalent to eating 100g red onion. A study reported on Superfoods showed an 8% reduction in uric acid levels on a daily dose of 500mg quercetin for one month. I eat lots of fruit and veg that naturally contain quercetin anyway, but 100g of onion daily would be a challenge! I'm trying this for a couple of months to see if it makes a difference.
