Dosage Recommendations

The therapeutic dosage of Quercetin is 600 3¸000 mg per day:

Many people who use supplemental Quercetin for the treatment of Allergies use a daily dosage of 1¸400 mg

Bioavailability
Quercetin was formerly regarded as being poorly absorbed orally¸ however recent studies (undertaken during 1996) show that some orally-administered Quercetin is absorbed:

Studies conducted during 1997 further elaborated on the bioavailability of Quercetin: the Quercetin in Onions is absorbed better than Quercetin in Apples (Apples’ Quercetin content is absorbed only 30% as efficiently as Onions’ Quercetin).

The elimination half-life of Quercetin is 20 to 72 hours (average 25).
Approximately 25% of orally-ingested Quercetin is absorbed by the Small Intestine. It is subsequently transported to the Liver via portal circulation¸ where it undergoes significant first-pass metabolism. Quercetin and its metabolites are distributed from the Liver to various bodily tissues.

In the plasma¸ Quercetin is strongly bound to Albumin.
Peak plasma levels of Quercetin occur 0.7 to 7 hours after its oral ingestion.
