Quercetin is one of the most abundant flavonoid molecules consumed in the human diet

Quercetin is one of the most abundant flavonoid molecules consumed in the human diet that has been widely recognised for its potential health benefits. Quercetin accounts of 75% of our daily flavonoid intake and is derived from vegetables and fruits like kale, onions, capers, grapes and berries as well as tea and red wine.

The average flavonoid intake varies considerably depending on the amount of fruits and vegetables consumed in the diet. In the USA, it is estimated that the average daily intake of Quercetin is around 10mg per day. A daily dose of IMUNI Immune Defence (2 capsules), contains 500mg of Quercetin which is around 50 times the average dietary intake.

There are many different types of Quercetin supplements available on the market, with some cheaper than others, and the quality and amount of active ingredient varies considerably. IMUNI Immune Defence incorporates the trademarked ingredient "QU995" which has been published in more than 50 peer-reviewed scientific journals. QU995 is the only Quercetin ingredient that has been found to have clinically significant effects on immune health as published in human clinical trials.
