Reviews for Evening Primrose Oil

AliX · Taken for less than 1 month April 24, 2021

“Gives me palpitations and stops me sleeping whenever I take it. Be careful as some people don’t react well to EP supplements. Has a strong effect on the nervous system and should be used with caution if you are taking other omega supplements.”

For Sjogren's Syndrome: “At the time I discovered an article by Dr. Oz about ways to relieve the symptoms of Sjogrens, my eyes were extremely red, swollen, itchy and dry. Nothing was helping - I was using a humidifier, and had tried numerous creams and lotions. Dr. Oz suggested a list of vitamins and oils of which Evening Primrose Oil was a significant part. I started taking 6 capsules daily and within 3 days could see some improvement. It has been 4 months now, and my eyes are completely back to normal. I don't even have to use my gel drops anymore.”

For Premenstrual Dysphoric Disorder: “Amazing! 1300 mg a day not only takes the edge off PMS/PMDD but chills me out every day. Also on Zoloft but EPO adds an extra something that relaxes me just right!”
