"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."

"Evening primrose oil capsules were recommended by a hairdresser for my hair loss. I asked my doctor if it was safe to use. She said it probably would be okay. Well, it wasn’t. I started to forget things, was confused often, had to triple check things like turning off the oven or the iron, and my memory was just breaking down so badly that I was getting severe anxiety about being able to find my way back home from the grocery store, did I remember to take the clothes out of the washer or dryer, did I forget to feed the dog or did I feed her and I don’t remember doing it? It got so bad my husband had to get my checkbook and straighten it out because I forgot to make entries. My doc ordered an MRI which thankfully came back as normal, but the symptoms got worse. It finally dawned on me that it all started after I started taking the evening primrose oil capsules. I stopped taking them several days ago and my thinking is clearer and my memory is better. It’s scary stuff."

For Sjogren's Syndrome "At the time I discovered an article by Dr. Oz about ways to relieve the symptoms of Sjögren's, 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 Hot Flashes "Nothing short of a miracle! I had at least a half dozen hot flashes a day (and nights) and couldn’t sleep. Within days of taking 1000 mg a day, I noticed less of them and less severe. Now, a month in, I have almost no hot flashes."

"I started taking evening primrose oil capsules a year ago. Mostly for my acne and mood swings and anxiety and stress. I am a different person now with better skin but not perfect! I have more confidence as my self-esteem has increased nicely due to not being anxious and self-critical. I'm not 100 percent sure if it is all the cause of taking evening primrose oil, but as long as I have been taking my dose every day, my life has definitely improved hugely!"

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!"
