Antioxidants and Endometriosis: New 2025 Evidence on Reducing Pain and Improving Quality of Life

Endometriosis affects an estimated one in ten women and individuals assigned female at birth, and for many, it brings far more than the “expected” discomfort of a menstrual cycle. Pelvic pain, severe cramping, pain with intercourse, abdominal bloating, fatigue, and inflammation can become daily realities. These symptoms are often debilitating, interrupting work, relationships, physical activity, and overall wellbeing.

Growing Research on Novel Treatments to help Target Pain

Endometriosis is strongly associated with oxidative stress (an imbalance between reactive oxygen species and the body’s ability to neutralize them). This imbalance contributes to inflammation, hormone disruption, tissue damage, and the heightened pain sensitivity experienced by many with endometriosis. By reducing oxidative stress, antioxidants may help interrupt some of these pathways and offer meaningful symptom relief.

The 2025 review found that several antioxidant interventions, including specific high-dose vitamins, melatonin, omega-3 fatty acids, resveratrol, N-palmitoylethanolamine (PEA), silymarin, astaxanthin, and garlic extract, were associated with improvements in pelvic pain, dysmenorrhea, and sometimes dyspareunia.

Pelvic pain and menstrual pain showed the most consistent improvements across studies, while pain with intercourse improved less frequently but was still noted in some trials. This aligns closely with what I see in practice: pelvic pain and dysmenorrhea often respond within the first two to three months of targeted antioxidant and dietary support, while dyspareunia tends to respond more slowly and usually requires a more multi-faceted, individualized approach.

While each antioxidant works through slightly different pathways, the overall findings of the 2025 review suggest that antioxidant therapy can help reduce inflammation, lower oxidative stress, and improve pain associated with endometriosis. Collectively, these interventions support more balanced inflammatory signaling, healthier cellular function, and improved resilience within pelvic tissues. When applied together as part of an individualized plan, antioxidants may contribute to meaningful reductions in pelvic pain and dysmenorrhea while helping regulate some of the underlying processes that make endometriosis symptoms so difficult to manage.

Medical Guidance is Crucial for Personalized Treatment Advice

It is important to highlight that antioxidant therapy needs to be guided by a clinician familiar with endometriosis. Doses and combinations vary significantly between individuals, and certain antioxidants can interact with medications or other hormonal therapies. For this reason, I do not recommend self-selecting supplements based on online information. A personalized plan based on your symptoms, nutrient status, digestion, hormone patterns, and inflammatory markers is essential for safety and effectiveness. Some products have been shown to be more beneficial for pain related to endometriomas and others more particular for dyspareunia, for example. So often I hear from people that may have tried these therapies in the past, but often at the wrong dose, incorrect combination and/or duration, and therefore did not find much improvement in the past. But with correct timing, dosing, combinations and tailoring it to the specific symptom picture for each unique endometriosis case I often see patients that note significant improvement in pain scores.

In my practice, antioxidant therapy is rarely used in isolation. When combined with dietary adjustments, lifestyle support, and individualized naturopathic treatment, acupuncture, many patients report significant improvements in their pain within just a few cycles. While not every person responds the same way, the overall experience is encouraging and aligns well with the growing body of research.

Looking for Help Navigating Endometriosis?

If you are living with endometriosis and struggling with pelvic pain, severe menstrual cramps, or symptoms that interfere with your daily life, there are evidence-based options that may help. A comprehensive assessment can clarify which strategies are most appropriate for your specific presentation and how to safely integrate antioxidant support into your treatment plan.

If you would like guidance tailored to your situation, you are welcome to schedule a consultation to explore the most effective next steps for managing endometriosis and supporting your long-term wellbeing.
