We conducted a double-blinded, placebo-controlled trial to assess evening primrose oil's effects on psychological symptoms in postmenopausal women. Participants received either 1,000 mg of evening primrose oil or a placebo for 8 weeks.
Our findings indicated a significant reduction in psychological symptoms among those taking evening primrose oil compared to the placebo group. Specifically, the intervention group showed a notable improvement in their scores.
While promising, we recognize that further research is needed to fully validate these benefits and ensure the long-term safety of evening primrose oil in clinical practice.

We investigated how evening primrose oil affects psychological symptoms in menopausal women through a triple-blind, randomized clinical trial. The study included 100 women who received either evening primrose oil or a placebo.
We found that those using evening primrose oil experienced significant reductions in psychological symptoms, as measured by the Menopause Rating Scale, while the placebo group showed no improvement.
This suggests that evening primrose oil may be beneficial in enhancing the quality of life for postmenopausal women by alleviating psychological distress.

We explored the effects of evening primrose oil (EPO) and fennel on menopausal symptoms and hormone levels, using a triple-blinded method with 125 participants over 8 weeks.
While both EPO and fennel showed significant changes in hormone levels compared to a placebo, the impact on psychological menopausal symptoms was not notably different between the two groups after treatment.
In the end, neither oil proved to be more effective than the other for alleviating menopause-related issues.

Bye, bye hot flushes. I'm in peri-menopause and struggled with hot flushes and fatigue. Within 2 to 3 days of taking this product along with a magnesium supplement, I realised I hadn’t experienced a hot flush. A few days later, my energy improved and my sleep was better. Nearly finished my first bottle and I feel sharper, able to focus compared to the scatterbrained confusion associated with peri-menopause. I wished for my old life back, thinking this was just how it would be until menopause, but this product has helped restore that.

This evening primrose oil has been a game changer for my wife, who suffered painful, irregular menstruation. Since taking one capsule daily for twenty years, her cycles have normalised. Her menopause was smooth; I credit evening primrose oil for that and believe it's invaluable for women's health.

Thank the hormone Goddesses for Evening Primrose! I began taking Jarrow Evening Primrose (1300 mg) with Black Cohosh around 8 months ago to tackle early menopause symptoms (hot flushes). Within 3 days, I realised this combination was exceptional. Symptoms diminished by 95%, and I felt blissful. I take one pill of each at bedtime, and life was good again. No more waking up in the night feeling overheated, or mid-morning flushes after breakfast. However, when I switched to a different brand, symptoms returned. Once I returned to Jarrow, I was symptom-free again within 3 days. I’m committed to Jarrow from now on and grateful for Evening Primrose and Black Cohosh.

Evening primrose oil reduces menopause symptoms
We examined the effectiveness and safety of Exelvit Menopause®, a nutritional product featuring evening primrose oil, among 156 menopausal women over 12 weeks. This study showed a notable decrease in various menopausal symptoms.
Participants experienced improvements, such as a 48% reduction in hot flashes and 46% in sleep disturbances. Symptoms like irritability and anxiety also decreased significantly. These results suggest that evening primrose oil can help alleviate menopause-related discomfort effectively.

We investigated the effectiveness of Lady 4, a natural remedy containing evening primrose oil and other ingredients, on menopausal symptoms in women.
In a study of 120 women, half received Lady 4, while the others took a placebo. We measured the results using a specific scale for menopause symptoms.
The findings showed a significant improvement in those taking Lady 4 compared to the placebo group, with many participants feeling much better. This suggests that Lady 4 could be a helpful option for managing menopausal symptoms.

I’ve been using borage oil to treat menopause symptoms and improve skin health. I believe it has helped significantly. I rarely experience hot flushes, and any I do are quite minor. Since I began taking borage oil, my skin also looks healthier and is acne-free.

Evening primrose oil shows limited effectiveness
We explored the effects of evening primrose oil (EPO) as a treatment for menopausal hot flashes through a systematic review of various clinical trials.
While we found that EPO reduced the severity of hot flashes when taken for under six months, it did not significantly impact the frequency or duration compared to a placebo.
Some participants reported mild side effects like nausea and headaches, and EPO did not perform better than black cohosh in longer periods.
Ultimately, the evidence remains inconclusive regarding EPO's effectiveness for hot flashes, highlighting the need for further studies.
