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.  There is a need for women also to reduce their estrogen levels because a higher lifetime exposure to estrogen may increase breast cancer risk. However, this article is not meant to cover this reason for blocking estrogen. It is meant primarily for men. 

Estrogen in Men

Although considered mainly a female hormone, estrogen is also vital in men and ensures the male body can function properly.

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

Excessive body fat can contribute to high levels of estrogen in men. Because of the negatives attached to a hormone imbalance many people may want to reduce estrogen levels with an anti-estrogen product.

What Is An Estrogen Blocker?

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

Overall the aim of both natural and pharmaceutial estrogren blockers are the same, to help to reduce estrogren levels and to avoid the drawbacks that high levels and  increased estrogren can produce in the male body.

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 growth and you may lose the gains you’ve already attained.

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 your body fat levels increasing, obviously leading to overall weight gain.

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 growth – it’s easier to put on muscle mass when you don’t have excessive levels of estrogen holding you back.

What ingredients should you look for in estrogen blocker supplements?

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

Over the counter, estrogen blocker supplements 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 male 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, grape seed 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.

Blackstone Labs Eradicate

  • Purpose built product - for estrogen blocking
  • Supports reduction in body fat
  • Promotes Libido, energy and stamina
Blackstone Labs Eradicate estrogen blocker

Eradicate by Blackstone Labs is a highly popular anti-estrogen product. The company itself is also well known among bodybuilders for all of their other quality products. 

Eradicate's main ingredient is Arimistane, which is the trademarked name for Androsta-3,5-diene-7,17-dione, which is a metabolite of 7 Keto DHEA, which does not convert into testosterone or estrogen. This drug is a suicide aromatase inhibitor (AI) meaning it will permanently bind to the aromatase enzyme and prevent estrogen rebound. 

This ingredient also reduces circulating levels of estrogen in the body, therefore promoting natural healthy testosterone levels. 

Some reviewers of the product have also indicated that it helped them to treat gyno (gynecomastia) effectively. 

Eradicate can be used while on or coming off a ProHormone cycle. The container comes with 90 capsules, and its nice that the recommended dosage is just 1 capsule 3 times per day, with a meal. Unlike others that are up to 8 capsules each time. 

Estrotase Maximum strength Estrogen Blocker

  • Aromatase inhibitor
  • Increase testosterone while decreasing Estrogen

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, 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 with the ingredients backed by independent studies.

Products like Estrotase are probably the closest thing we’ll ever get to experiencing an actual bodybuilding miracle.
