The human body, regardless of gender, produces both estrogen and testosterone. One’s gender determines which hormone is produced more – men naturally produce more testosterone and women naturally produce more estrogen.  

In men, having too much estrogen can lead to weight gain, muscle tone loss, and higher levels of fatigue and mental confusion.

Best Estrogen Blockers

This isn’t a slight against women – men’s body simply needs less estrogen and if there is too much in their system, it can be difficult or impossible to get the gains that they’re looking for. That is where estrogen blockers come in.

What is Estrogen?

Estrogen is a hormone produced by the body that is primarily responsible for maintaining sexual and reproductive health in women.

Estrogen is actually a broad term for a number of similar hormones such as estrone, estradiol, and estriol.

In women, estrogen is produced in the ovaries.  

In men, estrogen production is relegated to the adrenal gland, the testes, and fat cells throughout the body.

Excessive fat cells in the body can contribute to high estrogen levels in men.

Why Would Men Need An Estrogen Blocker?

Men naturally produce less testosterone as they age. If this happens too quickly or the testosterone levels decrease too much, health problems can occur.  

For bodybuilders, this lack of testosterone means that it will be impossible to improve your muscle tone and you may lose the gains you’ve already attained.

Estrogen blockers help to manage this by either reducing the amount of estrogen in the body or in the case of pharmaceutical estrogen blockers, preventing the body’s estrogen receptors from working.

What are the benefits of taking an estrogen blocker?

If you’re a man and your estrogen levels are out of whack, they can cause a host of different problems.  

You’ll find yourself putting on weight.  

It’ll be harder to put on muscle and harder to lose the extra pounds you’ve been packing on.

Estrogen even plays a part in your cardiac health – men with healthy levels of estrogen have fewer heart failure related deaths than those with estrogen levels outside the norm.

The main benefit of taking an estrogen blocker is improved muscle gains – it’s easier to put on muscle when you don’t have excessive levels of estrogen holding you back.

What ingredients should you look for in an estrogen blocker?

There are a number of different active ingredients that you should look for when you’re choosing an estrogen blocker.

Over the counter, estrogen blockers may not be regulated by the FDA, so it’s important to know exactly what’s in your supplement. Look for ingredients like:

  • Wild Nettle Root – Nettle is commonly used for prostate health and can act as a natural estrogen blocker by regulating the production of the hormone in the body.
  • Maca – A plant that was originally found in Peru, it’s been used in estrogen blockers since its discovery.  The evidence surrounding the use of maca for estrogen blocking is largely anecdotal.
  • Chrysin – A flavonoid, usually found in bee products like honey and in plants like passion flower, chrysin is thought to block estrogen and increase testosterone.
  • Grape seed extract – This supplement has been proven to act as an estrogen blocker in women who have passed menopause.While it hasn’t been studied yet in men, it should have the same effect as it does in women.
  • Zinc – This mineral is an important part of a healthy diet, but it can also act as an estrogen blocker.
  • Boron – This trace mineral might not appear in your normal multi vitamin, but it has been shown to decrease estrogen levels and increase testosterone levels.
  • Resveratrol – An antioxidant found in red wine, resveratrol has been found to suppress estrogen production in controlled tests. Unfortunately, the amount that you would need to consume to have any positive effect is 20x what you could safely take in most cases.

This is just a small sampling of the ingredients you might see in your supplement – there are dozens of natural supplement ingredients that have been used for estrogen blocking and testosterone improvements

You may find some estrogen blockers that use a proprietary formula – they don’t list the individual ingredients and their amounts on the label. Avoid these whenever possible.  They make it more difficult to make the best decisions for your health because you can’t know the amount of each ingredient, and there may be unlisted ‘inactive’ ingredients that could cause negative side effects.  

Are there any side effects from taking an estrogen blocker?

There is not a lot of information on the side effects of non-prescription estrogen blockers.  

Some men have reported joint pain after taking these supplements – estrogen does play a big role in bone health for both men and women – but these reports are just anecdotal at this point.

These supplements aren’t regulated by the FDA so they are not subject to the mandatory studies and human trials that prescription medications are.

What is the recommended dosage for over the counter estrogen blockers?

This is a difficult question to answer for one simple reason – the dosage recommendation will depend on the formula of the estrogen blocker you’re choosing to take.

Our best advice here is to follow the dosage instructions on your product.

When is the best time to take your estrogen blocker?

Again, this will depend on your specific product – depending on the formula, your supplement may instruct you to take two pills once a day, or two pills three times a day.

It’s important to stick to your product’s dosage schedule for optimum results.

Most estrogen blockers will also recommend a dosing schedule – taking the pills daily for 6-8 weeks, then take a 2-4 week break to allow the body to normalize before starting the cycle over again.  Each supplement formula will have its own dosing schedule.

Product Reviews

If you’re looking to add an estrogen blocker to your regimen but you’re not quite sure where to start, you’re in luck – we’ve done all the legwork for you.

Here are reviews for 5 of the top estrogen blockers on the market today, with a list of pros and cons. Hang out with us to the end to find out who the winner is!

Androsurge

Marketed as an elite estrogen blocker for men, Androsurge definitely lives up to its name.

This supplement is made up of a number of natural estrogen blockers, including vitamin D, Zinc, and grape seed extract.

It also includes diindolymethane (DIM) which has been shown to block estrogen and improve overall testosterone levels.

If you’re trying to avoid gelatin for dietary reasons, you’re in luck – the capsules for this supplement are made from veggies instead of animal gelatin.  

Plus, it comes with a 30-day money back guarantee so if you don’t see any results, it’s easy to contact the company and return the product.

Pros

  • Vegan – There are no animal products in this supplement. Even the gelatin in the capsules is sourced from vegetable products.
  • No Proprietary Blend – Each ingredient is spelled out with its name and dosage on the label.
  • Stacks Well – This supplement can be easily stacked with other products to produce optimum results.

Cons

  • None

Erase Pro +

Erase Pro contains 1000mg of a proprietary blend of herbs and extracts designed to help increase testosterone and decrease estrogen production.  Their primary ingredient is Ashwagandha Root Extract, which makes up 675mg of the 1000mg in each serving.  This root extract, also known as Indian ginseng, has been shown in some studies to improve thyroid function and block estrogen in men.

Each jar contains 30 servings, but we’re unsure how long this lasts because there isn’t a whole lot of information about the dosages.  If one serving equals one dose for the day, the jar is kind of expensive for a one month supply.

Pros

  • Natural ingredients – This supplement’s formula relies on natural ingredients such as root extracts to provide estrogen blocking qualities.

Cons

  • Proprietary Blend – Other than the ashwagandha root, it’s impossible to know the amount of each ingredient in this supplement’s proprietary blend.

PCT Surge

If you need a surge, PCT Surge is the estrogen blocker for you.  This supplement primarily uses flavonoids and antioxidants like chrysin and resveratrol to boost testosterone production and block estrogen.  

It also includes a number of natural ingredients such as fenugreek extract and Tongkat Ali, both of which have been shown to affect estrogen production.  

What sets this supplement apart is that it also includes ingredients for liver support – specifically, milk thistle and L-cysteine to help protect liver function while you’re taking hormone related supplements.

Pros

 

  • Natural ingredients – This supplement relies on natural ingredients to offer estrogen blocking and testosterone supporting coverage.
  • Liver support – This supplement also includes a blend designed to help support liver health, which is essential.
  • Cost effective – This is also one of the most cost effective supplements on the market – costing around $0.50 per serving.

Cons

  • Proprietary Blend – Surge relies on not one but three proprietary blends – one designed for estrogen blocking, one for testosterone support, and one for liver function.

Nolvadren XT

While this supplement may offer full transparency when it comes to its ingredients unless you’re well versed in supplement lingo, you might still be a little confused.That said, though, it is still an effective estrogen blocking supplement, offering a one month’s supply per bottle, the formula created specifically to increase testosterone while decreasing estrogen and controlling cortisol.

It’s marketed as a miracle pill, but it’s all science and in cases like these, products like Nolvadren XT are probably the closest thing we’ll ever get to experiencing an actual bodybuilding miracle.

Pros

  • Libido Boosting – In addition to improving testosterone production, this supplement helps to improve libido in some users.
  • Both Genders -This estrogen blocker can be by both men and women who need more testosterone in their systems. (Note: Women should discuss estrogen blockers with their doctor before taking them – a lack of estrogen can cause health problems)

Cons

  • No Proprietary Blend, But… – Nolvadren is transparent with its ingredients if you’re a scientist. The supplement facts rely on the scientific names of the ingredients.

Estrodex

Last but definitely not least on our list is Estrodex by SAN Nutrition.

This supplement is marketed for bodybuilders looking for good post cycle therapy support (PCT) and includes ingredients designed to decrease estrogen levels by preventing the body from turning testosterone into estrogen.

That’s about all we can tell you about the ingredients – we don’t speak German and that’s what they wrote the ingredients in.

The only other downside of this product is that if you follow the dosing instructions on the label, one 90-capsule bottle is only a 15 day supply, so you end up spending effectively twice as much on this supplement as you would on other similar products.

Pros

  • Blocks Conversion – This particular estrogen blocker prevents testosterone from turning into estrogen, lowering overall estrogen levels and increasing free testosterone levels.

Cons

  • Ingredients in German – They may not use a proprietary blend but that doesn’t matter unless you read German, which is the language their nutrition labels are written in.
  • Short Supply – A bottle of 90 capsules is only a 15 day supply if you follow the suggested dosing instructions.
