It was the objective of this study to investigate the effects of an oral supplementation of quercetin in three different doses of plasma concentrations of quercetin, parameters of oxidant / antioxidant status, inflammation, and metabolism. Ingestion of quercetin can be associated with a reduced risk of coronary heart disease and other degenerative diseases. Because quercetin can be obtained from edible plants, such as: apples, berries, and onions, it was estimated the average western diet would provide between 0 to 30 mg and an average ingested dose was 10 mg. The primary dietary sources of quercetin in Western populations are red wine, tea, fruits and vegetables. In other countries, quercetin is available as a supplement of daily doses ranging from 200 to 1200 mg. Quercetin can also be used as nutraceuticals for functional foods within a concentration range of 10 to 125 mg per serving. Read the rest of this entry »
