Quercetin is not an essential nutrient. It is found in red wine, grapefruit, onions, apples, black tea, and, in lesser amounts, in leafy green vegetables and beans. However, to get a therapeutic dosage, you'll have to take a supplement.
Quercetin supplements are available in pill and tablet form.
A typical dosage is 200 to 400 mg 3 times daily. A special type of quercetin, quercetin chalcone, is claimed to be absorbed better, but there is little reliable evidence to prove this.
While these are promising results, the study was small and cannot be regarded as definitive. Furthermore, researchers failed to provide the usual statistical evaluation required for such studies (a statistical analysis that directly compares the results in the treatment group against those in the placebo group). Thus, further study will be necessary to discover whether quercetin is actually effective for prostatitis.
