Evening primrose oil shows promise
We analyzed how different types of dietary fats might influence breast cancer growth. In our study, we used athymic mice with human breast cancer cells and supplemented their diets with evening primrose oil and fish oil, while others received olive oil or a standard diet without essential fatty acids.

We found that the tumors in the mice receiving evening primrose oil were significantly smaller compared to those on a standard diet — suggesting that increasing essential fatty acids could play a beneficial role in managing breast cancer.

Evening primrose oil enhances tamoxifen
We explored the potential of evening primrose oil (EPO) to enhance the effects of tamoxifen—an established breast cancer treatment. In laboratory tests using human breast cancer cell lines, EPO showed promising results, working alongside tamoxifen to encourage cancer cell death and stop cell growth.

While our findings suggest that EPO can improve tamoxifen's anticancer abilities, more research is needed to fully understand its impact on breast cancer treatment in patients.

Evening primrose oil shows limited effects
We conducted a randomized, double-blind, controlled trial to explore the effects of fish oil and evening primrose oil (EPO) on breast cancer patients undergoing chemotherapy. Over 12 weeks, participants received either the oil supplements or a placebo.

While we noted improvements in fatty acid profiles in the treatment group, the study showed no significant changes in inflammatory markers between the two groups. Despite a decrease in IL-6 levels in the intervention group, there was no major benefit observed overall.

Ultimately, our findings suggest that while this supplementation can help with lipid metabolism, it does not deliver significant anti-inflammatory effects for breast cancer patients undergoing chemotherapy.

Miracle drug
I researched evening primrose oil for a while before deciding to try it without expecting much. To my surprise, it worked wonders! I recommend it to anyone with issues like mine. I have high prolactin that causes chest pain and engorgement throughout my cycle. After trying many medications, I truly didn't think evening primrose oil would help, but it’s a miracle! My chest feels normal, with no pain at all, and I'm taking it alongside DIM.

Wide-ranging benefits
Evening primrose oil has remarkable properties, particularly for women. It aids in treating conditions like fibrocystic mastopathy and breast cancer, normalising hormonal balance, and relieving PMS symptoms. It's beneficial for women facing conception issues and helps alleviate menopause symptoms, including hot flashes. Besides women's health, it can address hormonal disorders in men. Regular use may reduce bad cholesterol and support heart health. It can also improve skin issues and hair loss, making it a versatile supplement.

Effective for mastopathy
This product is ideal for women suffering from mastopathy. It yielded excellent results; I experienced no more breast pain. After just a week of use, I felt relief. Despite the capsules' large size, I found them easy to swallow, and the product is of high quality with little to no smell.

Comfort from discomfort
This supplement is excellent, especially when combined with DIM. My breast pain before my cycle has significantly decreased. As a woman with a larger bust, the discomfort was challenging. Now, I feel much lighter and more comfortable. The menstrual cycle is back on schedule, which had been a problem previously. I’ll continue taking primrose, giving it a solid 5 stars.

It alleviates severe breast tenderness and also helps with mood and cramping. I'll continue purchasing this brand as it truly works wonders for me.
