White Button Mushrooms Extract: A Recipe to Lower Estrogen Levels

​A white button mushroom extract (Agaricus Bisporus, Champignon's, fungi), is probably the best natural aromatase inhibitor you can find.

Not only is this mushroom cheap, safe and readily available; when they are consumed in more substantial amounts on a daily basis, they can efficiently decrease levels of estrogen and help boost testosterone levels.


All while also leaving most of the 5α-Reductase enzyme and DHT levels untouched (libido benefits etc.), which most other mushrooms types do not.


This article is a short guide on how to best reap the benefits that white button mushrooms have to offer and show you their anti-estrogenic superpowers in all their glory. But first, let's go back to the basics.

​The aromatase enzyme can be seen as the master regulator of male and female hormones in the body.


Having high levels of aromatase enzymes equals more testosterone being converted into estrogen (the female hormone).


Women naturally have higher levels of estrogen (which is why its called the female hormone), and they require less testosterone than what we men do.


The enzyme tends to accumulate in fat cells which are also why women have naturally higher levels of body fat (curvy) than men.


Men require estrogen to a degree to maintain healthy sexual function and bone mass.

​Now to all guys that are interested in boosting their testosterone levels, balancing levels of estrogen are crucial.


The best way to do this is by reducing the levels of aromatase enzyme which downregulates the production of estrogen, thereby maintaining higher levels of testosterone.

If you where to go see your doctor or endocrinologist about your excess estrogen problem, it is likely they would prescribe you a pharmaceutical aromatase inhibitor such as Anastrozole/Arimidex.


Arimidex was initially researched as a treatment for breast cancer in women (which is primarily fueled by excess estrogen levels).


It works equally well to lower estrogen levels in men as it does in women; however, it is a very powerful drug and if improperly dosed can leave you with tanked estrogen levels for weeks on end.


Driving estrogen levels too low is equally bad as having too high levels and usually brings about a lot of suffering in the form of joint pain, dehydration, anxiety, depression and loss of sex drive. In such a case, make sure you keep track of them by conducting regular blood tests:

Pharmaceuticals should always be seen as a last resort when you have already tried everything else to fix your hormonal issues.


For most guys, there is simply no reason to go all hardcore with Arimidex and risk messing yourself up in the process.


Which is why in this article we want to introduce you to the best natural aromatase inhibitor that can help sort out your excess estrogen problems, increase testosterone and do so entirely without side effects. Did we mention that it is cheap as well?

​While many kinds of mushrooms tend to be anti-estrogenic by inhibiting aromatase (reishi, oyster, lion’s mane etc), one inherent problem with many of them is that they also tend to inhibit the enzyme 5-Alpha Reductase (5-AR).


5-AR is the enzyme that converts testosterone into the more potent androgen DHT (Dihydrotestosterone). DHT is responsible for the libido and mood (alpha feeling) benefits that you get from testosterone as well as also being anti-estrogenic in its own regard.


In other words, ideally, you want more DHT and less estrogen, so consuming too many mushrooms that also inhibit 5-AR can be contra productive to our goals.


The great thing about white button mushrooms (Agaricus Bisporus) is that they possess the lowest 5-AR inhibiting effects of all mushrooms, resulting in something along the line of 1-2.5% inhibition only, as outlined in this study (picture below).


This makes white button mushrooms a very attractive food for lowering estrogen levels without any side effects or potential anti-androgenic effects.

​Now that we have established why white button mushrooms are the best mushroom for men to consume, let’s take a look at the science supporting its anti-estrogenic effects.


Most of below studies have been made on women (because of breast cancer research) but they are equally relevant to men as the process of lowering estrogen is the same in both sexes.



    1.    Researchers at The Beckman Research Institute found that consuming white button mushrooms decreased estrogen levels in a dose-dependent manner, meaning the more you eat, the greater the effects. 


    2.    In this year-long study done by Chinese researchers, the combination of a diet high in mushrooms and green tea was investigated to reduce the risk of breast cancer (from excess estrogen). There was a significant statistical effect observed where such a diet showed reduced risk. It would have been interesting to see the same study done on prostate cancer as both are cancers that are hormonally driven by excess estrogen. 


    3.    The following study investigated dried white button mushrooms extract as a treatment to reduce estrogen levels, and the results confirmed a reduction in aromatase enzyme as well as estrogen (estradiol, E2) levels after 12 weeks of daily consumption. The minimum effective dosage of extract seemed to translate back into around 100-130g mushrooms per day and for significant effects you would likely have to consume 2-3x this dosage. 


​White button mushrooms are one of those essential foods that we recommend all guys to consume as often as possible.


Most guys notice a positive effect on libido and morning erections after consuming a few hundred grams of white button mushrooms daily for a couple of days straight. It's really such a cheap and straightforward hormonal hack.


If you struggled with balancing your estrogen levels in the past or have issues with obesity, gyno, erectile dysfunction or hot flashes it is likely that consuming more mushrooms on a daily basis can help resolve them over time.
