Based on 6 Researches

Cameron M, Gagnier JJ, Chrubasik S. Herbal therapy for treating rheumatoid arthritis. Cochrane Database Syst Rev. 2011. doi:10.1002/14651858.CD002948.pub2

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.

I have been using evening primrose oil for a long while, and I can only share positive experiences. At 52, I started taking it for hot flashes, and it certainly helped. Additionally, it provided relief for my knee problems associated with rheumatoid arthritis. It’s noted that gamma-linolenic acid can alleviate the chronic inflammation pain typical of rheumatoid arthritis, making this oil a valuable addition to my routine.

Helps! My doctor prescribed me to take Femikaps for mastopathy, two capsules twice daily for three months. It’s rather expensive; however, it has been effective. I sought a more affordable option and found this oil, which has a similar dosage. I took it for three months, and my breast pain ceased to exist. After nine months, there have been no new nodes, and I plan to repeat the course to maintain the results.

Evening primrose oil moderately effective

Anxiety details

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.

The best thing ever! I purchased it at full price and began with another brand but switched after noticing this one at a lower price. We are on our second bottle and love it! It's great for anxiety, sleep issues, and stress. Before taking these vitamins, I experienced hair loss and sore breasts. Both my partner and I now sleep much better and feel improved overall. I won't go without these supplements again; they really work!

Bloating details

Bloating relief noted

Fine. The quality is usually good for this brand. I tried it for the first time to ease my period and moisturise my skin. After a month and a half of use, I can say the period has truly become easier. I didn't even notice the start, and there was no discomfort in my stomach at all. The bloating in my intestines has also gone away.

Breast Cancer details

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.

Miraculous product! Evening primrose oil has a significant positive effect on the female body! I began taking it six months ago due to hormonal disruption that caused an irregular menstrual cycle and lack of ovulation. My primary aim was to restore and maintain my health. After starting the oil, I felt its healing effects within two weeks, experiencing the signs of ovulation I hadn’t felt for ages. Since then, evening primrose oil has been my constant companion, helping me to restore a normal 28-day cycle, alleviate symptoms of premenstrual syndrome, and reduce pain during menstruation. My nails have improved, too, becoming stronger and glossier.

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.

Sleep Apnea details

I began taking this with some doubt, but the results surpassed all expectations. One capsule at night is sufficient for me; I avoided morning doses due to hypotension. At night, I sleep deeply and wake up feeling rested. Crucially, the hot flushes have stopped, which had been troubling me before.

I feel the benefit from this product as it lowers inflammation related to my adenomyosis. I'm experiencing greater hormonal balance and even think it has improved my skin.

Evening primrose oil benefits heart health

Heart Disease details

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.

The last time I purchased this supplement in gelatin capsules, I couldn’t immediately assess its effectiveness.

I am grateful to IHERB and all the reviewers as their input is invaluable in choosing supplements, especially since medical professionals are not always reliable.

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.

Cardiovascular improvement

Most Useful Review

1 people found this helpful

Evening primrose oil is an essential source of polyunsaturated fatty acids, particularly Gamma Linolenic Acid (GLA). It helps alleviate symptoms of cardiovascular disease, normalises blood pressure, and improves heart function. Additionally, it may relieve PMS symptoms and reduce the intensity of hot flashes during menopause.

Rapid skin improvement

Excellent! I had to order this after discontinuing contraceptive pills; my skin was in poor condition. I read it’s beneficial to take primrose oil afterward. Within just three to four days, my skin improved significantly. The pimples that appeared due to fatty and sweet foods disappeared. I have ordered more because I'm very pleased with the results.

After reading positive reviews, I started taking this for hormonal issues post-pregnancy. Within a month, I've noticed my libido restored, which had diminished after my first birth. Although I usually experience no menstrual pain, I had significant discomfort initially, yet my cycle shortened from five to three days. I did experience a few breakouts, likely from skincare changes. I would highly recommend this product!

I took this when my doctor prescribed it for uterine fibroids. It is undoubtedly one of the best medications for women's health.

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.

Toxicol Mech Methods. 2024;34:469. doi:10.1080/15376516.2023.2301357

We investigated how evening primrose oil, enhanced with gamma-linolenic acid and D/L-alpha tocopherol, could protect against liver damage in a rat model. In this study, male rats were divided into four groups, including a control and treatment group.

We found that the evening primrose oil group showed improvements in liver health compared to those exposed to carbon tetrachloride, a harmful substance. While liver enzymes returned to safer levels and tissue damage was reduced, the oil’s effectiveness emphasizes its potential benefits for supporting liver health.

Indispensable for women's health, I use it in the complex treatment of endometriosis at a dosage of 1300 mg twice a day. Primrose contains gamma linolenic acid (GLA), which suppresses inflammatory and autoimmune processes. What have I noticed? Critical days have become quite regular, without pain or spasms. Hormones are balanced, with no bias towards oestrogen. It is suitable for women with painful menstrual cycles and to prevent oestrogen-dependent diseases. It reduces unpleasant symptoms, such as hot flashes, during the climacteric period.

Evening primrose oil reduces LDL cholesterol

Based on 3 Researches

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.

This is a fantastic oil! In my second month of use, I found relief from the unbearable menstrual pain and headaches I had suffered from all my life. The first month, I had some pain, but primrose stopped it. In the second month, I didn't need painkillers at all; my stomach pain disappeared entirely. My headaches also ceased, but I'm unsure if that's coincidence.

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.
