Quercetin helps support seasonal immune function and is a treatment option for allergies. It has antioxidant and anti-inflammatory properties. The combination with Bromelain may provide relief for seasonal allergies.
If you have ever eaten an onion, apple or berries, or drank tea or wine, you have ingested a flavonoid called quercetin. Flavonoids are compounds found in many fruits and vegetables (mostly in the skin and leaves). Studies have shown a wide variety of properties in various flavonoids including anti-inflammatory, anti-thrombogenic, antidiabetic, anticancer, and neuroprotective activities.
Bromelain is a digestive enzyme extracted from pineapples, and often found in digestion formulas. In addition to acting as a digestive aid for high protein foods, bromelain can also positively influence the immune system. It is used in herbal medicine to help relieve minor pain, swelling and inflammation. Bromelain is a mucolytic agent, which means it breaks down mucus.
The Role of Quercetin in Allergies and Asthma
In testing, quercetin clearly inhibits the allergic cascade that results in the unpleasant symptoms associated with hay fever (allergic rhinitis). Clinical trials have supported the interest in quercetin as a possible solution to congestion, the secretion of excess tears, itching and other bothersome symptoms of hay fever.
How Much Quercetin is Needed?
Most people get about 5 to 40 mg of quercetin daily from food. In order to reach therapeutic doses of quercetin (usually in the range of 200-500 mg per day), one would require a very high consumption of whole fruits and vegetables. Certainly, supplements are a much more realistic and sustainable source of the therapeutic levels of quercetin. NOW® quercetin is extracted from the seed of the Fava D’Anta (Rutin) plant in Brazil. NOW® has demonstrated superior outcomes in studies. For best absorption, quercetin supplements should be combined with a meal containing fat and fibre.
