Before we even get started on whether or not Estrovera works, or if whether it is a good option as a menopause supplement, we have to say that there is nothing special about it and it is of course overpriced when you consider it’s a single ingredient supplement, with other well known brands offering the exact same thing for less.
As such we obviously can’t recommend that anyone should buy Estrovera when there’s an identical alternative available for half the cost in Estroven. The ingredient that it’s made of is of course patented, meaning that neither of these companies in question actually make it, they’re just putting a label on it.
But, that doesn’t mean that Estrovera is the best choice, just that there’s a cheaper option if all you’re looking for is a Siberian rhubarb extract supplement. Now, Siberian rhubarb isn’t a bad ingredient, but it’s not the all singing and dancing supplement it’s often touted to be. And there are other ingredients that can be as, if not more effective than the singular one in Estrovera.
For about $10 a month more you can get menopause supplements that contain Siberian rhubarb in the same dose, as well as about a dozen other ingredients that have been shown to reduce menopause symptoms. Meaning they’ve got a much higher chance of having an ingredient that you respond well to.
Customer reviews of Estrovera vary widely. Some women report positive results, including reduced hot flashes and improved mood. Others, however, have not experienced significant relief from their menopause symptoms while using Estrovera. This is ultimately why we say that the ingredient in Estrovera is good in a combined supplement, because it seems to be a 50/50 shot as to whether or not it works.
Estrovera Amazon Reviews
Amazon reviews of Estrovera are very positive, but even a quick search shows something rather odd, for example, there are a lot of 4 and 5* reviews that seem to say the product doesn’t work. Which usually means that customers who leave a negative Estrovera review are simply offered a refund to change the rating.
There are also a few reviews that simply don’t seem to make any sense and talk about other products all together, citing positives like the taste, which usually suggests paid reviews meaning that their 4* average is likely a little bit overblown and based on our manual count it looks more like it should be a 3. Which is what we’d expect from a supplement like estrovera relying on this one ingredient.
Reddit Reviews of Estrovera
At the time of writing there don’t seem to be many legitimate Estrovera Reddit reviews, there’s a thread with some people saying it works, and some saying it doesn’t. Again it’s about half and half. But, the full reviews do look like they’ve been written by the marketing team.
The only active ingredient in Estrovera is Siberian rhubarb extract
This extract is believed to have the potential to reduce hot flashes, night sweats, and other menopause symptoms. However, the specific effects of this ingredient on hormone levels and symptom relief are mixed. Estrovera’s ingredient has been around since the 90’s so there is a reasonable amount of studies although 2 in particular are the most cited in it's favor.
This first was a placebo-controlled trial published in Menopause in 2006. This trial investigated the efficacy and safety of ERr731 in perimenopausal women with severe hot flashes. The study involved a 12-week treatment period, and the results showed significant improvements in menopausal symptoms, as measured by the Menopause Rating Scale. 
The second most commonly cited study published in 2008 aimed to demonstrate the efficacy of ERr731 for menopausal issues over a longer period (6 months). The researchers enrolled 363 menopausal women with symptoms and administered ERr731 for six months. The results revealed a significant decrease in the MRS total scores. This mostly effected hot flashes and mood, but other scores improved as well. As such it is reasonable to make claims that estrovera should have some improvement to menopausal symptoms. 
The catch is that in the real world it seems to only really be effective for about 50% of people, and several other trials showed that the Siberian rhubarb in estrovera was not effective. However, because it’s such a small ingredient, it is perfect for combined supplements that use other natural ingredients for menopause symptoms.
Estrovera is primarily sold through their main site and amazon, and the usual
retail price for Estrovera is around $34.95 per bottle. Which
considering Estroven which is exactly the same costs $19.95, we would suggest that
All in all
Estrovera isn’t awful, there’s some decent evidence to suggest that the Siberian
rhubarb extract they use can have some benefit towards hot flashes, night
sweats and mood regulation for people with menopause, but there is a cheaper
option available. And if you’re looking for a premium menopause supplement,
then this definitely isn’t a good option.
You can get something that contains the same ingredient, as well as pretty much everything else that’s actually been shown to work for about $10 a month more. Or you can by the same thing for $10 a month less. Generally we recommend EstroCare for most people looking for something at the high end of menopause supplements as it contains pretty much everything and the kitchen sink.
As such there really isn’t any reason for us to recommend Estrovera. It’s fine, and there’s nothing wrong with it. It’s just not very good value.
