The Top 5 Best Estrogen Blockers For Men That Really Work


What Is An Estrogen Blocker?

First things first – what is an estrogen blocker?

An estrogen blocker, also known as an anti-estrogen, is a natural supplement designed to help reduce how much estrogen exists and is functioning in the human body.

Usually, they’re taken to treat a hormonal imbalance between estrogen and testosterone levels. Some men may be overproducing estrogen. In that case, an estrogen blocker steps in to help reduce those levels and combat any adverse effects caused by that overproduction.

Hormonal imbalances can lead to such problems as fatigue, poor erection quality, low libido, mood swings, depression, and loss of muscle mass.

If you’re experiencing some of these problems, we highly recommend you keep reading this article.

The Top 5 Estrogen Blockers For Men On The Market

Finding a high-quality and effective estrogen blocker for men is challenging. Many products don’t use the right ingredients or measure out in incorrect dosages. We’ve spent a lot of time researching this type of product.

Now, we’re ready to present you with the top 5 best estrogen blockers for men. Keep reading to see our list.

#1. Rebirth



What’s our number one best estrogen blocker on the market? Our favorite, and the best hands down, is Rebirth by Huge Supplements. With 11 ingredients total, you’ll get 2-3 times as much potency when compared to the alternatives.

It only uses clinically effective ingredients to reduce the presence of estrogen while raising testosterone. There’s also a bit of a ‘kick’ to it, usually felt as a result of lessening the feeling of fatigue that usually comes along with excessive estrogen. The magnesium in the mix adds to that energy boost as well.

Rebirth contains aromatase-inhibiting ingredients like Diindolylmethane (DIM) and Acacetin (5,7-Dihydroxy-4-methoxyflavone). It battles against estrogen conversion, and it stacks well with any other supplements. In fact, doing so may optimize your results.

Depending on your goal, you can use Rebirth for 1-3 months, take a 1-2 week break, and start it up again for another 1-3 months.


These are a few of the ingredients in Rebirth, along with some of their benefits.

  • Ashwagandha (500mg) – There are a lot of claims as to what ashwagandha can or can’t do. It’s recommended for low blood sugar, inflammatory diseases, and even cancer. Importantly, it’s suggested that it can elevate testosterone.
  • Magnesium aspartate (45mg) – Magnesium is linked to sperm production and energy.
  • Zinc (25mg) – Like magnesium, zinc is excellent for energy and heart health.
  • Safed Musli (500mg) – A naturally occurring anti-inflammatory that is awesome for muscle recovery. It’s possible, according to some studies, that it can increase sperm levels.
  • D- Aspartic acid (2000mg) – Many of the natural bodybuilding supplements you’ll find will say that they can raise testosterone. If they’re suggesting as much, it might be because they contain D-Aspartic.
  • Vitamin D3 (2000IU) – Linked to testosterone production and energy.

This is a laundry list of ingredients that all work together to naturally increase the production of testosterone. They’re also great at inhibiting the chemicals that contribute to estrogen.

As a bonus, they also increase cortisol, lower blood sugar, and fuel powerful muscle growth.

There are always going to be symptoms coming along with starting a new hormone treatment. However, we noticed they weren’t as potent as with other estrogen blockers, especially when balanced with plenty of water.

There’s no denying it – Rebirth by Huge Supplements is the best estrogen blocker for men on the market nowClick here if you want to visit the official product page.

#2. Erase Pro

erase Pro


Rolling in at second place is Erase Pro. This is a hardcore product that will lower estrogen and increase testosterone. It retails for $47.95, which isn’t too bad a price.

It uses only three different ingredients, which are KSM-66, Pine bark Extract, and Indole-3-Carbinol. It binds to estrogen receptors at the site, stopping the effects of this hormone in its tracks. The product takes about 4-8 weeks to start showing effects.

We did notice a few downsides. It leaves a little bit of joint pain behind, usually from the ‘drying’ effect on muscles. If you want to counter than, try lowering your dosage to once every other day.

Erase Pro also kept us up at night, likely from some of the stimulants in the solution.

Overall, though, this was a potent mix that got the job done pretty well.

#3. Estroblock Pro



Estroblock is all-natural and is great for regulating hormone levels in the body. It’s made from a DIM proprietary blend. According to the manufacturer, that will lower your risk of estrogen-related cancers. The downside to this proprietary blend is that you don’t know exactly how much of each ingredient you’re getting.

DIM, for the uninitiated, is a natural substance found in some cruciferous vegetables – kale, broccoli, cauliflower, etc. It’s thought that DIM can have a hand in managing hormone levels should they dip too low or climb too high.

This blend also has phosphatidylcholine. You’ll usually find this in eggs, mustard, and sunflowers. It’s a great source of brain food, helping with anxiety and memory loss. There are positive reviews backing it up, though it seems to be more effective in treating cystic acne rather than leveling out hormone levels.

#4. EstroHalt



The effects of EstroHalt seem to start showing signs of working after about three weeks, at least in our trials. From what we can tell, when those three weeks passed there was already a noticeable drop in estrogen from when we started.

EstroHalt also includes Indole-3-Carbinol. It breaks down in the body and effectively becomes DIM, just as you’d find in Estroblock. I3C is also a potent aromatase and estrogen blocker that keeps certain enzymes from warping testosterone into estrogen.

Another crucial ingredient is flaxseed oil powder. This fat increases the rate at which I3C and DIM absorb. This might have been why we started seeing results so quickly. It’s not a particularly strong anti-estrogen, but it’s still a competent blocker.

The headaches that come with starting a new hormonal reduction supplement will be present with EstroHalt – but that’s a sign that the product is working hard and fast. It’s strong stuff, so we recommend you start with half a pill. You also need to take EstroHalt consistently if you want to guarantee results.

#5. AndroSurge



Jacked Factory’s AndroSurge boasts that it will help with muscle growth, improved strength, and possibly even an increase in libido and vitality.

One of our favorite facts about AndroSurge is that it uses Rhodiola as a stress mitigation ingredient. That ingredient also reduces cortisol and supports masculine health. Other testosterone-boosting ingredients with additional health benefits include vitamin D and zinc.

Though, we have to say, the vitamin D factor here could be upped significantly. It’s much too light of a dosage. It also does not have any magnesium.

It also contains “Long Jack” which stimulates the release of free testosterone from binding proteins. It’s supposed to improve your overall health profile, but there’s not much evidence there to back it up.

Androsurge also lowers your blood pressure – and that can be a blessing or a curse, depending on your current health conditions.

The Best Ingredients In Estrogen Blockers

When it comes to estrogen blockers, we’re picky about our ingredients. We need to see a certain roster to know that estrogen blockers are made from ingredients that are going to be impactful, potent, and proven to work.

There are a lot of ingredients that could contribute to a great estrogen blocker, and there are definitely more than what we have time to list here.

Additionally, some may work better or worse for you than they do for others – it’s all a matter of your body’s chemistry.


Referred to here a few times as DIM, we like to see this ingredient in our estrogen blockers. When you eat cruciferous vegetables, indole-3-carbinol is broken down by your stomach acids. regulates estrogen levels – especially when they’re abnormally high.

Another plus of an estrogen blocker with DIM is that it will stop fat cell formation in its tracks. That’s great for bodybuilding and general weight loss.

As it corrects hormone imbalances in men, it will also lessen the associated symptoms, such as erectile dysfunction and gynecomastia. It will also reduce the effects of water retention – usually caused by excessive estrogen.

If that wasn’t good enough, it can also help fight against prostate cancer. It does this by staving off prostatic intraepithelial neoplasia (PIN). PIN is a condition that is associated with prostate cell growth, usually as a precursor to cancer.


This antioxidative flavonoid compound doubles as an anti-inflammatory. While that’s good for your overall health, the punch comes from the way Acacetin can considerably inhibit aromatase.

Aromatase is an enzyme that converts the androgens, or male hormones, in your body into estrogen. Certain studies have shown that acacetin will suppress aromatase.

It does this fairly well even in small doses because it’s so potent. That’s good news, because smaller dosages mean minimized side effects.

You want to see this on the label of your next estrogen blocker.

Grape Seed Extract

Grape seed extract is a potent antioxidant that may also inhibit aromatase. Studies have shown that this extract can affect testosterone levels in men.

While the impact isn’t as intense as what you’d get from a synthetic testosterone supplement, low dosages over a long period will build up into some impressive results.


Another proficient combatant against estrogen in the body, chrysin along with other ingredients in an estrogen blocker can theoretically decrease estrogen in the body.

Chrysin is a flavonoid usually found in passionflowers, some geraniums, and silver linden. It’s often used in applications of bodybuilding, and to naturally treat gout, inflammation, and anxiety.

It’s suggested that this flavonoid can not only keep estrogen at bay, but increase levels of testosterone as well.

Symptoms Of High Estrogen In Men

Are you worried that you might have high estrogen, but not quite sure? Here, we’ll lay out some of the symptoms of high estrogen in men.

While you may be experiencing some of these side effects, you won’t be able to get a clear, 100% read on your hormone levels without reaching out to an endocrinologist. This is just to give you a starting point in deciding what to talk to your doctor about.

Mood Swings

High estrogen in men is reflective of a hormonal imbalance. In the human body, hormones have a hand in many ordinary bodily functions – including the parts of the brain that monitor and manage emotions.

Because of this, sudden bouts of anger, sadness, or anxiety can fluctuate, coming on stronger than usual or without necessary provocations. If you’re noticing that you’re riding an emotional rollercoaster these days, it could be a sign that there’s something amiss with your hormones.

With many of these estrogen blockers, you’ll see the benefit of lowering cortisol. When estrogen levels soar, the stress hormone cortisol rises with it. This can cause irritability and, of course, added stress. Added stress only adds to moodiness, creating a feedback loop of emotions.


As with all hormonal imbalances, having less than the normal amount of testosterone can lead to a lack of energy, a sense of grogginess, and an inability to take part in everyday activities. This can be associated with depression, comorbid with mood swings.

Sleeplessness is another occasional side effect of heightened estrogen. If you’re not getting enough sleep at night, you’ll definitely feel the weight of that fatigue during the day.

Extreme fatigue and tiredness can last for hours or even days at a time, making every day seem like an exhausting slog to get through.

Taking one of the best estrogen blockers for men will block more estrogen and add on a burst of energy, allowing you to hop back into your life without wanting to pass out.

Low Libido

Losing interest in sex once in a while is normal, and can be part of having a partner, or just getting older. However, an uncharacteristically low sex drive for an extended amount of time could be a sign that there’s something more going on than just not being in the mood.

Androgens and estrogens are both responsible for maintaining male libido – as well as preventing erectile dysfunction. When imbalanced, excess estradiol can lead to diminished libido and poor erection quality.

Specifically, when testosterone levels dip below 300 nanograms per deciliter, men are considered to have low testosterone.

This can be frustrating, embarrassing, and not something anyone wants to deal with. Thankfully, the energy boost that a lot of estrogen blockers, like Rebirth, can help bump your libido back to where it was.


Another well-known symptom of high estrogen in men is gynecomastia. The imbalance of hormones in the body, particularly an influx of estrogen, will lead to an increase in gland tissues in the breasts.

Thankfully, this is more of a cosmetic issue than anything, and won’t harm your quality of life. It’s a symptom that many find annoying at best and distressing at worst. Thankfully, it can be cleared up by taking a good quality estrogen blocker.

As long as you remain in good physical health and stay on a workout regimen, you’ll see the effects of gynecomastia reducing as you continue to use the product.

Should You Start Taking An Estrogen Blocker?

Estrogen blockers can be a great supplement if you are experiencing high estrogen levels/symptoms. They’re natural, and in many cases, they’re extremely effective – especially if you can get your hands on a potent product like Rebirth.

Doing your research and finding a product that works for you will go a long way in helping you achieve your goals and balance out your hormones.

Before you start taking any kind of supplement, especially one that involves your hormones, consult a physician – preferably an endocrinologist.

They’ll be able to help you find the ingredients and dosages that will have the best effect and the most muted side effects based on your personal chemistry.

Estrogen Blocker For Men FAQ

Here, we’ll break down a few more of the questions you could still have about the best estrogen blockers for men.

What Does An Estrogen Blocker Do For Men?

While many people tend to think of estrogen as an exclusively female hormone, it is present in everyone’s bodies, regardless of sex. However, there should be a certain balance to how much testosterone and estrogen are in someone’s body. As men get older, they may begin to overproduce estrogen.

When someone’s estrogen levels get too high, and testosterone drops, men can experience a number of symptoms. Some of these symptoms include:

  • Excess water retention
  • Fatigue
  • Poor erection quality
  • Mood swings
  • Loss of muscle mass
  • Depression and other associated mood disorders
  • Difficulty maintaining or getting an erection

The purpose of estrogen blockers is to help balance out levels of estrogen and androgen. Usually, they will block the production of new estrogen and encourage the development of testosterone.

It’s a great solution for those who are experiencing the frustrating effects of excessive estrogen. It will help metabolize and decrease the amount of estrogen pumping through your system, allowing you to feel like yourself again.

When Should I Take My Estrogen Blocker?

Taking your estrogen blocker first thing in the morning on an empty stomach is advised. That way, you can repeat the benefits of these supplements throughout the entire day.

How Long Does It Take For An Estrogen Blocker To Work?

Usually, you’ll start noticing the effects within a couple of days. Again, for some, it may take a little longer. Everyone’s systems work differently, and those products and ingredients will absorb faster in some than in others.


The best estrogen blockers in men will include ingredients that are proven, or at least highly suggested, to be effective in inhibiting aromatase and boosting testosterone levels. We took the liberty of hunting around for the best of the best, and we found a clear winner.
