Quercetin shows promise for IC
Treatment of interstitial cystitis with a quercetin supplement.
Preliminary but positive results
We recently tested a quercetin-based supplement, Cysta-Q, on 22 patients with interstitial cystitis (IC) in an open-label trial. Over 4 weeks, participants took two capsules daily, and we assessed their symptoms before and after treatment.

The results were encouraging; all patients reported improvements in their problem and symptom indices, as well as pain levels. Interestingly, everyone but one individual experienced some positive change, and there were no side effects reported.

These promising findings suggest that quercetin could be beneficial for those suffering from IC, although larger, controlled studies are needed for confirmation.

Quercetin shows protective effects
Quercetin protects against chronic prostatitis in rat model through NF-κB and MAPK signaling pathways.
Study relevant to pelvic pain
We sought to understand how quercetin could alleviate chronic pelvic pain associated with Chronic Prostatitis/Chronic Pelvic Pain Syndrome (CP/CPPS) using a rat model. Over four weeks, rats received oral quercetin while measuring various blood and prostate health markers.

Our findings revealed that quercetin improved prostate health by reducing inflammation and enhancing antioxidant capacity. Specifically, it lowered levels of harmful inflammatory markers and suppressed certain signaling pathways known to contribute to pain. Overall, quercetin showed significant protective effects against CP/CPPS.

Quercetin aids endometrial cell responses
Quercetin enhances decidualization through AKT-ERK-p53 signaling and supports a role for senescence in endometriosis.
Potential for future treatment insight.
We investigated how quercetin, a potential treatment for endometriosis-related pelvic pain, affects endometrial stromal cells. By using cells derived from menstrual effluent of both unaffected individuals and those with endometriosis, we observed quercetin's role in promoting decidualization, which is vital for embryo implantation.

Although the study shows promising mechanisms behind quercetin's effects, the direct benefits on reducing pelvic pain require further clinical exploration. Our findings suggest that while quercetin improves cellular responses, additional studies are needed to confirm its effectiveness as a treatment for chronic pelvic pain.

Less foot pain
Quercetin alleviates foot pain and inflammation for me. As someone who is overweight, I struggle with pain in my soles and ankles, and this supplement helps. It’s said to protect Resveratrol from being metabolised by the liver, so I ensure a higher dosage. I remain cautious due to some studies suggesting possible side effects, yet I find it beneficial overall for my foot pain.

Quercetin shows promise for endometriosis pain
Effectiveness of the integration of quercetin, turmeric, and N-acetylcysteine in reducing inflammation and pain associated with endometriosis. In-vitro and in-vivo studies.
High relevance for endometriosis research.
We explored the effectiveness of a combination treatment involving quercetin, curcumin, and acetylcysteine for easing pelvic pain in women with endometriosis. In this study, 33 women took the supplement daily for two months while we monitored their pain levels related to dysmenorrhea, pelvic pain, and dyspareunia.

The results were promising, showing a significant reduction in pain symptoms and decreased reliance on NSAIDs. We observed that this treatment may serve as a helpful addition to managing endometriosis-related pain without notable side effects.

Quercetin alleviates pelvic pain
Effects of the hydroalcoholic extract of Phyllanthus niruri and its isolated compounds on cyclophosphamide-induced hemorrhagic cystitis in mouse.
Highly relevant to treatment effects.
We explored the effects of Phyllanthus niruri extract and its isolated components, including quercetin, on hemorrhagic cystitis induced by cyclophosphamide in mice. The study involved treatment before and after inducing the condition and assessed pain, swelling, and bleeding.

We found that quercetin led to significant pain relief, while other compounds like gallic acid and rutin showed notable anti-inflammatory effects. Overall, the extract and its components proved beneficial in alleviating the treatment's side effects, suggesting potential therapeutic value.

Quercetin aids pelvic pain relief
Phenotypically directed multimodal therapy for chronic prostatitis/chronic pelvic pain syndrome: a prospective study using UPOINT.
Significant findings on treatment
We examined the effects of multimodal therapy on chronic pelvic pain using the UPOINT system. After 27 weeks, 100 patients receiving tailored treatments, including quercetin for organ-specific symptoms, showed notable improvement.

About 84% experienced significant symptom reduction, highlighting a median drop in pain scores from 11.5 to 6.1. While quercetin appeared beneficial, there was no guarantee that the number of symptoms predicted the outcome. Overall, this approach signifies a step forward in managing chronic pelvic pain effectively.

Quercetin may reduce pelvic pain
Quercetin in men with category III chronic prostatitis: a preliminary prospective, double-blind, placebo-controlled trial.
Relevant score indicates strong findings.
We examined the potential of quercetin, a bioflavonoid, in alleviating pelvic pain in men with chronic prostatitis syndromes. In a randomized, double-blind trial involving 30 men, those taking quercetin experienced a notable reduction in symptoms compared to those on a placebo.

Specifically, 67% of men on quercetin showed a 25% improvement in symptoms, compared to just 20% in the placebo group. Even more encouraging, a follow-up with additional participants using a quercetin combination showed an impressive 82% improvement. Overall, quercetin is well tolerated and may significantly help for many facing chronic pelvic pain.
