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! Now Foods offers effective products at reasonable prices. Don't lose hope; restore your health!

This product is miraculous for painful breasts. For nearly a year, I experienced swollen and painful breasts almost throughout the month except during my period. After starting a 1300 mg softgel daily, I noticed immediate improvement. I even reduced it to every other day, amazed at the rapid results. I take many supplements, but I’ve not experienced such dramatic changes before.

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 how evening primrose oil affects cardiovascular health in rabbits fed a high-fat diet.

Additionally, the oil boosted prostacyclin synthesis, which plays a key role in keeping blood vessels healthy.

Our analysis showed that evening primrose oil reduced platelet adhesion and the size of arterial wall lesions. This suggests it may support better vascular health by enhancing the endothelium's ability to prevent blood clots.

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 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.

Enhanced sleep quality

I strive to achieve good sleep by combining various supplements, with evening primrose oil being essential. One to two capsules daily suffice for most, and they are safe for long-term use without causing dementia.

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.

I have no complaints about the packaging, and the capsules are easy to take. After three months, I've noticed my cycle has improved, and my hair and nails are growing better. It has also led to a slight drop in my high cholesterol levels, which is encouraging.

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.

Balances hormones
Most Useful Review
Classical and long known for its benefits, evening primrose oil is commonly used by gynecologists. It has an unusual composition, being effective for various problems. I have been taking it to balance my hormones and prevent Osteoporosis, and the effects are always noticeable. Using evening primrose oil during menopause is regarded as very beneficial. It is a potent tool for hormone regulation, so consulting a doctor is advised if there are hormone-dependent conditions. Additionally, I utilise primrose as an anti-inflammatory supplement, and I have heard dermatologists recommend it for acne and eczema.

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.

I began taking evening primrose oil to adjust my disrupted menstrual cycle. Although it restored my cycle within a month, I also learned about its benefits for psoriasis. Following the Pegano Diet, I combine it with omega-3 and vitamin D3 for better results. While the improvements take time, I've noticed a positive change in my health.

I've been taking these for over a year. Since entering menopause, I experienced occasional migraines, likely due to hormonal imbalances. As soon as symptoms arise, I take two of these, and they subside within ten minutes. I also find they help with caffeine-related breast pain.

I've been taking SPO for over three years and swear by it. When I run low, I purchase two bottles immediately. Before this, I suffered monthly cramps with headaches, nausea, and bloating. After two cycles on SPO, my symptoms diminished by the third month, leaving just some bloating, which I can manage by cutting back on salt. It has been effective for me.

Now Foods is brilliant! I initially bought evening primrose oil to address my persistent sweat rash. After taking it for some time, my sweat rash did not return! I will monitor it, particularly during the summer months, hoping that taking the oil will continue to help.
