Quercetin is a flavonoid polyphenol found in plants. Itâs a predominant compound identified in onions â On average making up to 43% of a Red onion (1). Quercetin has been long known for itâs antioxidant activity, and positive modulatory effect on the immune system. Quercetin has been shown to balance the innate immune system, inhibit histamine release and IgE anti-body formation (allergy response) (2), making it a go-to supplement in those with inflammatory and/or allergy conditions.
