The effect is undeniable! I am 44 and have endometriosis, which resulted in very heavy, prolonged menstruation, leading to considerable anaemia. I began taking evening primrose oil, and already from the first menstruation, I noticed a significant difference! The blood loss decreased dramatically, and my menstrual period now lasts only 3-4 days. I've nearly finished the first jar, taking one capsule daily with meals. When I took a break in my intake, everything returned to how it was before. Now, I continue without interruption and will reorder more!

Thank you, iHerb! Evening primrose has really helped restore my hair from diffuse alopecia. I've tried many things with no results, but after two months using a complex of ingredients including evening primrose, I see new strong hairs growing in areas that hadn't produced any for a long time. My period pains have also stopped; it doesn't hurt on the first day anymore. After eight months, my hair is slowly recovering, which feels like a victory!

As a recent breast cancer survivor, I struggled with intense hot flashes, which I call "power surges". A friend suggested NOW Super Primrose oil. After following her advice and the dosage recommendations, I began to experience relief. Initially, I had a significant reduction in the nightly power surges. A month on, I almost no longer have these disturbances, even during the day, unless stressed. I'm grateful for this discovery.

I did not expect such positive results from evening primrose oil! At 50, I experience the challenges of menopause. After reading reviews, I decided to switch from red clover to this one capsule. I stopped taking the clover with some trepidation, but the expected hot flushes did not materialise. I have been taking one 1300 mg capsule at night for about two weeks, and to say I am pleased would be an understatement. I have started to visit the lavatory without issues! This nice surprise from primrose meant I could stop using psyllium husks, which delighted me. A bottle lasts me about four months, especially if I share it with friends. I am currently very satisfied and highly recommend it to anyone facing similar challenges. Thank you for the "likes" if this aids in your decision! Wishing everyone good health free from hot flushes and constipation!

I have been taking evening primrose oil for the second year, and the results are very positive. My chronic endometriosis has improved; I now have small lesions that are asymptomatic. The nodes formed in mastopathy have disappeared from my chest. I did not follow the doctors' appointments and solely relied on primrose. The ultrasound results were surprisingly favourable. My daughter, who struggled to conceive for a decade, became pregnant after just a month of taking primrose. I was astonished. Thanks to this supplement, I was able to stop the hormones I had been taking for about 15 years. I am incredibly grateful to iHerb for the chance to regain our health.

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.

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.

In our exploration of treatment options for mastalgia, we focused on the effectiveness of evening primrose oil combined with vitamin E. Conducted at King George's Medical University, the study assessed 106 female patients suffering from breast pain.

We measured psychological status using the DASS-42 scale and pain using a visual analog scale. While topical NSAIDs showed a strong response rate, evening primrose oil and vitamin E had a notable effect in 6.98% of patients.

Overall, both treatments proved valuable, though we found no correlation between psychological conditions and pain severity.

We examined the effects of evening primrose oil, high in gammalinolenic acid, on cholesterol levels in nineteen patients with high cholesterol. This study used a rigorous crossover design where participants received both the evening primrose oil and a placebo safflower oil over 16 weeks.

During the evening primrose oil treatment, we noticed a significant reduction in low-density lipoprotein (LDL) cholesterol levels and apolipoprotein B in patients without hypertriglyceridemia. These findings suggest that evening primrose oil can be beneficial for individuals struggling with high cholesterol.

Super Primula has been a part of my routine for women's health since 1997. It positively affects hormone balance, supports healthy pregnancies, and is effective at lowering high cholesterol levels. With its unique gamma-linolenic acid content, it significantly benefits the skin, blood vessels, and overall wellbeing. Highly recommended.

Evening primrose oil is Omega 6. On my doctor's recommendation, I've taken it alternating with Omega 3. During my period, I used to struggle with extensive pain and nausea in the first two days. After starting this regimen, my well-being improved significantly. My periods are now much less painful and noticeable. I strongly recommend this product.

I absolutely love this product! I've been taking it consistently for two months and have felt amazing. My anxiety has lessened and I fall asleep easily. Most impressively, the PMS symptoms have diminished drastically; my abdominal pain, breast discomfort, and headaches during this time have vanished. I also use the oil for my skin, which has improved significantly. My combined skin type has balanced out, looking smooth and nourished. I highly recommend this oil for both internal and external benefits!

We examined the effects of Efamol Marine, a blend of evening primrose oil and fish oil, on patients with psoriatic arthritis (PsA). Over nine months, 38 participants were divided into two groups: one received Efamol Marine and the other a placebo.

Despite the initial laboratory indication of some anti-inflammatory effects, such as changes in specific serum markers, we found no significant improvements in skin or joint symptoms in clinical assessments. The need for NSAIDs remained unchanged, suggesting that larger doses might be necessary for noticeable benefits.

Excellent! Evening primrose oil is rich in omega-6 fatty acids that can alleviate PMS symptoms. It also reduces itching and inflammation in various skin conditions, including psoriasis. This oil has greatly helped with my PMS and abdominal pain, particularly on the first days. Now, I constantly use it. I highly recommend it for all women, as it protects our health and effectively eases period pains.

This study explored whether evening primrose oil (EPO) could replace non-steroidal anti-inflammatory drugs (NSAIDs) for people with rheumatoid arthritis (RA).

Over 12 months, we noticed that patients taking EPO showed notable subjective improvements and were able to reduce their NSAID intake.

However, a follow-up after three months of placebo indicated that while they felt better initially, their symptoms returned.

Importantly, EPO didn't change underlying disease progression, meaning it may not be a cure but can support symptom relief.

We looked at how evening primrose oil, rich in gamma-linolenic acid, might help patients with rheumatoid arthritis. In a 6-month double-blind study, 40 participants took either evening primrose oil or a placebo. While some mild improvements were noted in morning stiffness for those on the supplement, overall, the benefits were not significant. Interestingly, olive oil also showed notable effects in reducing pain by the study's end. Therefore, evening primrose oil may offer some benefits, but olive oil deserves attention for its own positive outcomes.

We investigated the role of evening primrose oil in improving skin conditions for acne patients undergoing isotretinoin therapy. In a controlled study, participants were monitored over nine months to assess changes in skin hydration, oiliness, and body weight.

While evening primrose oil helped boost skin hydration, it didn't significantly outperform isotretinoin alone in other areas like oiliness or weight loss. This suggests that evening primrose oil may provide some benefits, but it doesn't drastically change the overall treatment outcome for acne patients on isotretinoin.

We examined the latest insights into herbal therapies for rheumatoid arthritis, including evening primrose oil. Our analysis included 22 studies, revealing moderate evidence suggesting that gamma linolenic acid (GLA), found in evening primrose oil, may ease pain and disability related to RA.

However, while some benefits were noted, the evidence remains mixed and the risk of side effects should not be overlooked. More comprehensive studies are needed to firmly establish its effectiveness for RA treatment.

We examined how dietary supplements, specifically evening primrose oil (EPO), impact heart health in older rats under stress. Rats that received EPO showed a notable reduction in severe ventricular fibrillation compared to those fed sunflower seed oil without gamma-linolenic acid (GLA).

Interestingly, while borage oil, which contains more GLA, didn't provide any extra benefits, it indicates that GLA plays a crucial role. However, the findings primarily apply to aged rats, so further studies are necessary to determine the overall effectiveness in heart disease management in different populations.

I purchased this product on the advice of friends who had similar symptoms. I suffered from breast pain and swelling for a good two weeks before menstruation. After taking it for almost two months, I noticed a significant reduction in symptoms. My period came without any pain, and even my severe headaches have gone. I’m really pleased with the results!
