Quercetin prostate benefits are helpful for men suffering from prostate cancer, prostatitis, and enlarged prostate (benign prostatic hyperplasia, or BPH). This phytonutrient is often found in supplements that are formulated to support prostate health because of its potent antioxidant qualities. Dietary sources of quercetin include tea, onions, apples, berries, red grapes, and red wine.
There are several studies showing that quercetin has earned a place as one of the top supplements for prostate cancer. In 2010, researchers from the University of Madras reported that quercetin reduced the survival of certain prostate cancer cells. Quercetin changed signaling between cells and caused cells to die.
Other studies have also demonstrated that quercetin fights prostate cancer in multiple ways. This phytonutrient can inhibit genes associated with cancer development plus cause cell death and inhibit prostate cancer from spreading. For these reasons the study’s authors stated that quercetin could be developed “as a novel chemopreventive agent for metastatic prostate cancer.”
Prostatitis is an inflammatory condition of the prostate, so quercetin’s anti-inflammatory properties make it a good supplement for managing prostatitis symptoms. Because quercetin blocks the production and release of histamine and other inflammatory factors, this phytonutrient is particularly helpful for chronic nonbacterial prostatitis/chronic pelvic pain syndrome (CP/CPPS) sufferers. This common ailment causes men to experience pelvic pain, urinary symptoms, blood in the urine or semen, and painful ejaculation.
Quercetin prostate benefits seem to stand out in studies on CP/CPPS. A Cleveland Clinic study involved 100 men with CP/CPPS. It used a multimodel therapy approach that is based on the UPOINT (Urinary, Psychosocial, Organ Specific, Infection, Neurologic/Systemic, Tenderness of Skeletal Muscles) system to categorize a patient’s symptoms and select therapies based on those categories. Therapies might include taking alpha blockers for urinary symptoms, doing physical therapy, or taking supplements, such as quercetin. The study was 26 weeks long, and there was a 50-week follow-up. At the follow-up, 84% of the men in the study dropped at least 6 points in their scores. The therapy with the biggest drop in score was quercetin.
Twenty-eight men participated in a double-blind and randomized study. These CP/CPPS patients took either a placebo or 500 mg of quercetin twice daily for one month. Another 17 men (as part of an unblind addition to the study) took a supplement that contained quercetin, saw palmetto, bromelain, cranberry, and papain.
At the end of the month, the men who took quercetin for prostatitis had their International Prostate Symptom Scores (IPSS) go down from 21.0 to 13.1. The placebo group’s scored declines from 20.2 to 18.8. Sixty-seven percent of the quercetin group reported at least a 25% improvement in their symptoms, but only 20% of the placebo group reported improvements. The majority of the men who took the supplement containing quercetin, saw palmetto, bromelain, cranberry, and papain reported least a 25% improvement in their symptom score.
The American Urological Association says that more than 50% of men over 60 have enlarged prostate (BPH), and 85% of men over 90 are affected by BPH. Scientists have found that combining quercetin with a common medicine for BPH offers better prostate-size reduction than drugs alone. When researchers working with rats with enlarged prostate combined finasteride (Proscar) with quercetin, the scientists found that the combination of the two caused an improved reduction in prostate weight. Not only that, but as the quercetin dose increased, the results got better as well. Talk to your doctor about possible drug side effects before taking Proscar.
Quercetin health benefits are not just limited to prostate health. This phytonutrient may also help with allergies, which may make it even more worth looking into for some men. You can find quercetin supplements alone or in combination formulas with other natural ingredients. For example quercetin combines really well with saw palmetto to promote prostate health. One of the best prostate supplements, called Prost-P10x, is a formulation that contains 500 mg of quercetin, 640 mg of saw palmetto, and several other natural prostate supplements. Formulas for prostate health make it easy to get many quercetin prostate benefits in a daily dose.
A typical daily dose for someone looking to get quercetin prostate benefits is 500 mg. Do not take more than 1 gram daily without talking about quercetin with your healthcare provider. Possible side effects of quercetin may include headache and upset stomach.
