Practitioner Testimonials

"Estrovera is a life changer for patients as well as doctors."
~ R. Gulati, MD

"The majority of people notice a difference in their menopausal symptoms within two weeks to a month on Estrovera. Some people's symptoms diminish to the point where they aren't bothered by them anymore, and other's see complete relief from all their symptoms. Estrovera is a win-win situation because it works and because there are no side effects associated with it. This product sells because it works!"
~ J. Cochran, ND

"Estrovera is easy, inexpensive, and safe, and there is heavy anecdotal evidence that shows that it works for a lot of people, so it's effective, too. I believe introducing lifestyle changes and optimizing health is something that needs to be done first before exploring riskier options like hormone replacement. As a physician, I would rather be a soundboard or an advocate for optimizing a patient's lifestyle with foods and safe remedies that can either ease their symptoms or almost eliminate them. With Estrovera, you don't have to be a salesman or consistently encourage people to use it—they will come to you and keep asking for it because it works!"
~ R. Lazarus, DC


Patient Testimonials

"This product WORKS!! Even with a bio-identical creme treatment, my hot flashes were debilitating, exhausting and totally embarrassing. Three months on Estrovera and the hot flashes are occasional instead of always occurring; mild instead of major' tolerable instead of torture. I recently experimented with taking them every other day but rapidly discovered I have no desire to return to that land of torment."
~ G. Lungle

“I have had almost no hot flashes since beginning this product!”
~ C. Babson

"Without Estrovera I would be living in the Arctic or spending most the day and night with my head in the freezer! I am so not kidding! About 5 weeks ago I started Estrovera as recommended by my naturopath as a natural approach to hot flashes. I had been seriously struggling for about 5 months and the hot flashes had just become unbearable and happened about every hour day or night. My heart would race and I couldn't sleep and I was just exhausted. I "get" that after 44 years of periods, my body is confused and needs time to sort this all out, but I was so tired and felt unwell and weak and ready to give up and go the HRT route. This is going to sound like an infomercial, but Estrovera has helped me so much. My hot flashes have probably been reduced so that I only have one about every couple of hours and the intensity is reduced by about 50% as well. I am also taking other vitamins to support my changing body, eating healthy and avoiding a lot of triggers. I can honestly say that without Estrovera, I would be on HRT. I am so very grateful for this natural support! I am looking forward to even more improvement over the next couple of months."
~ P. Sheasby

"Prior to Estrovera, I had major hot flashes and extreme sweating every 45 minutes, all day and all night. My shirt would be wet, my hair would be wet, and I wasn't able to get any sleep. After the first two weeks of taking Estrovera, I was able to sleep six hours straight! Estrovera makes my life so much simpler, and I feel so much cleaner now that I'm not sweating and drenching constantly. It has changed my hot flashes and my life and allows me to finally get a good night’s sleep."
~ R. Hale, patient

"I would classify myself as perimenopausal—I have irregular cycles, mood fluctuations and night sweats, which prohibited me from being able to sleep. I began seeing relief from my symptoms in about two weeks after taking Estrovera. Now I am able to sleep through the night and my temperament is much more moderate. Estrovera is a product that women in all stages of menopause can benefit from because it is healthy and it is a simple solution with great, positive outcomes."
~ D. Joy, patient
