If you suffer from hormonal headaches, this is a lifesaver! I've tried other brands at higher doses, which gave me headaches. However, this dose is perfect. My headaches around my period are virtually non-existent when I take this daily.

Irritable Bowel Syndrome details

I regularly take Evening Primrose Oil, and with the high concentration, I only need one pill a day. It aids my overall health and has improved my irritable bowel syndrome. I haven't experienced cramps, just mild bloating, so I won't stop taking them.

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.

Blurred Vision details

Relieves visual strain

As I entered my 50s, my eyesight began to decline, prompting me to purchase lutein in the hope of seeing improvement. This small, round pill is easy to take daily. I bought it to address issues like blurred letters, floaters, reduced visual clarity, and eye strain. Although I've just started using it, I’m eager to see changes in my vision as I continue, and I already sense a welcome difference in my eyes.

Evening primrose oil shows promise

Based on 3 Researches

Pritchard GA, Jones DL, Mansel RE. Lipids in breast carcinogenesis. Br J Surg. 1989;76:1069.

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.

I tried this superhero butter out of curiosity, and it completely eradicated my PMS symptoms for months! Previously, I experienced breast soreness for 10 days prior to my period, but now I hardly notice any symptoms. I forget about my monthly cycle entirely—no pain or discomfort at all! I might take it a few times a year. Thanks, iHerb! I’ll definitely remember it for when I eventually give birth!

Evening primrose oil improves vascular health

Possibly Effective

Based on 16 Researches

Villalobos MA, De La Cruz JP, Martín-Romero M, Carmona JA, Smith-Agreda JM, et al. Effect of dietary supplementation with evening primrose oil on vascular thrombogenesis in hyperlipemic rabbits. Thromb Haemost. 1998;80:696.

We investigated how evening primrose oil affects cardiovascular health in rabbits fed a high-fat diet. Over six weeks, we found that it contributed to lower cholesterol levels and improved beneficial HDL-cholesterol. 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.

Hair Loss details

Good for female hair loss! I've experienced extreme hair loss over the past few years, losing about three-quarters of my hair. My doctors attributed it to childbirth, but my child is now 2.5 years old. After researching, I started taking saw palmetto, evening primrose oil, and iron. A few months later, I've noticed my eyelashes and leg hairs growing back, and I assume my head hair is too. One or more of these remedies are working! The herbs are safe, so they’re worth trying if you’re dealing with hair loss.

Support for my mother. This programme for the elderly is an extension of the health support plan I've developed for her. Currently, we aim to remove excess fluid and uric acid, purify blood vessels, and support her cardiovascular system. Although many of these supplements may not show quick results, a small miracle occurred with my mother. After just two weeks, her arrhythmia has disappeared, and the pain in her kidneys has lessened considerably. While swelling has decreased, sleep has also improved. I consider every small step toward improvement a victory at her age (80). I trust these high-quality supplements and hope my information is beneficial to others.

Enhanced mood stability

Primrose stabilises insomnia, depression, autonomic disorders, and other conditions like menopause or old age, featuring high-quality natural ingredients. It alleviates excess stress, stimulates brain function, improves concentration, and normalises sleep and mood. The medium-sized capsules contain GABA, a neurotransmitter that enhances sleep quality, especially when growth hormone is predominantly released at night, limiting stress effects for deeper, more effective rest. The dosage is optimal.

Endometriosis details

Jarrow evening primrose is excellent at a fair price! It has significantly helped me with my endometriosis and reduced painful cramps as well. I believe this product would benefit many women experiencing similar conditions!

Acne details

Kaźmierska A, Bolesławska I, Polańska A, Dańczak-Pazdrowska A, Jagielski P, et al. Effect of Evening Primrose Oil Supplementation on Selected Parameters of Skin Condition in a Group of Patients Treated with Isotretinoin-A Randomized Double-Blind Trial. Nutrients. 2022;14. doi:10.3390/nu14142980

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.

If I can assist anyone struggling like I have through a simple review, I would be pleased. This item has helped clear my hormonal acne. In my 30s, I've struggled to find anything to stop hormonal breakouts. I hate being on the pill because of how it makes me feel. I've tried various prescription topicals, but only antibiotics worked, which I don’t want to take indefinitely. After three months, I've noticed a huge difference, particularly within a week.

Biagi PL, Bordoni A, Masi M, Ricci G, Fanelli C, et al. A long-term study on the use of evening primrose oil (Efamol) in atopic children. Drugs Exp Clin Res. 1988;14:285.

We explored the effects of evening primrose oil on children's atopic eczema over a 20-week period. Initially, we observed that kids who took this oil showed significant improvement in their skin conditions after just four weeks. Remarkably, those benefits continued throughout the entire treatment duration. Along with these clinical improvements, we also noted changes in the fatty acid composition in the children's blood cells. Despite these positive findings, it's worth noting that opinions about the effectiveness of evening primrose oil vary among researchers, making the overall consensus somewhat unclear.

Heart Disease details

Evening primrose oil benefits heart health

Charnock JS. Gamma-linolenic acid provides additional protection against ventricular fibrillation in aged rats fed linoleic acid rich diets. Prostaglandins Leukot Essent Fatty Acids. 2000;62:129.

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.

We explored the effects of evening primrose oil on menopausal hot flashes in a 6-week clinical trial involving 56 women aged 45-59. Participants received either evening primrose or a placebo and reported their hot flash experiences using a specific questionnaire.

While both groups showed improvement, evening primrose oil notably reduced the severity of hot flashes compared to placebo. Specific improvements were also found in social interactions and sexuality for those taking evening primrose, making it a promising option for managing hot flash symptoms.

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.

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.

During my menstrual periods, I previously relied on strong painkillers due to significant pain. Seeking a healthier alternative led me to evening primrose oil. Although it wasn't a complete solution, I noticed considerable improvement in my overall well-being, with reduced nausea and vomiting during menstruation. It genuinely works!

Ishikawa T, Fujiyama Y, Igarashi O, Morino M, Tada N, et al. Effects of gammalinolenic acid on plasma lipoproteins and apolipoproteins. Atherosclerosis. 1989;75:95.

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.

Just received, I’ve been considering this supplement for a long time and finally decided on two cans! I’ve been suffering from night sweats and need to try something.

The quality of the ingredients appears to be excellent!

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.
