Best Anti Estrogen Supplements For Men Review 2024

February 15, 2023January 2, 2024 Anthony Conigliaro BSc 1873 Views

Estrogen is typically associated with the female hormone but is also present in men, albeit in smaller amounts. Maintaining a healthy estrogen balance in men is important for overall health and well-being. However, certain factors such as age, diet, environmental toxins, and medical conditions can cause an increase in estrogen levels in men, leading to unwanted side effects such as decreased muscle mass, increased body fat, and even breast enlargement. To counteract the effects of high estrogen levels, men can turn to anti-estrogen supplements, which work by blocking the effects of estrogen or reducing its production. This blog will look at some of the best anti-estrogen supplements for men.

What Are They?

Estrogen blockers are substances that can help reduce the effects of estrogen in the body by blocking its action or decreasing its production. (1) They are commonly used by both men and women who are seeking to regulate their hormone levels for various reasons, including athletes who want to enhance their performance, bodybuilders who want to decrease body fat and increase muscle mass, and women who are experiencing symptoms of estrogen dominance, such as mood swings, irregular periods, and breast tenderness.†

Estrogen blockers can have several other terms, such as:

Anti Estrogen Pills
Aromatase Inhibitor
AI

How Does Estrogen Blocker Work?

Testosterone can convert to estradiol through aromatization. Estrogen blockers work by inhibiting the conversion of testosterone to estrogen or preventing estrogen from binding to estrogen receptors in the body. However, in doing so, other hormone levels can increase. This increase can include gonadotropin-releasing hormone, LH, and follicle-stimulating hormone levels. As a result of these increases, serum testosterone levels also may increase. (2) This can help support an increase in strength, libido, muscle growth, improved mood and cognition, and fight fatigue. (3,4)

Who Should Take It?

Estrogen blockers can benefit both men and women who are experiencing high levels of estrogen or its effects on the body. Here are a few examples of individuals who may benefit from taking estrogen blockers:

Athletes: Some athletes, such as bodybuilders, may take estrogen blockers to help reduce body fat, increase muscle mass, and improve athletic performance. This is because high estrogen levels can interfere with muscle development and cause an increase in body fat.†
Men with low testosterone: Men with low testosterone levels may also benefit from taking estrogen blockers, as low testosterone can lead to an increase in estrogen levels in the body. By blocking the conversion of testosterone to estrogen, estrogen blockers can help restore a healthy balance of hormones in the body.†
Women with estrogen dominance: Women experiencing symptoms of estrogen dominance, such as irregular periods, mood swings, and breast tenderness, may also benefit from taking estrogen blockers. By reducing the amount of estrogen in the body, estrogen blockers can help alleviate these symptoms and restore hormonal balance.†

Suppose you have just finished a cycle of prohormones/a testosterone-boosting supplement. In that case, an estrogen blocker could be helpful for Post Cycle Therapy (PCT) or natural testosterone support. When you increase testosterone, some of this testosterone will convert to estradiol. Therefore, adding a supplement that can impede aromatase synthesis can promote the effects of the testosterone booster more efficiently. (3,4)

What Causes High Estrogen In Men?

When the estrogen level in a man’s body becomes too high, it can lead to various symptoms, including reduced muscle mass, increased body fat, and other health issues.

Here are some common causes of high estrogen levels in men:

Obesity: Men who are overweight or obese are more likely to have high estrogen levels, as fat cells can produce estrogen.†
Aging: As men age, their testosterone levels tend to decrease, which can lead to a relative increase in estrogen levels.†
Medications: Some medications, such as certain types of antidepressants and steroids, can interfere with the body’s ability to regulate estrogen levels.†
Environmental factors: Exposure to certain chemicals, such as pesticides and plastics, can also interfere with the body’s ability to regulate estrogen levels.†
Medical conditions: Certain medical conditions, such as liver disease, can interfere with the body’s ability to metabolize estrogen, leading to an increase in estrogen levels.†
Genetics: Some men may have a genetic predisposition to high estrogen levels.†

Some of the most common signs of high estrogen levels in men include:

Decreased libido: High estrogen levels can cause a decrease in testosterone levels, which can lead to a decreased sex drive.†
Erectile dysfunction: High estrogen levels can interfere with the normal functioning of the penis, leading to difficulty achieving or maintaining an erection.†
Gynecomastia: This condition is the development of breast tissue in men, which can be caused by increased estrogen levels.†
Increased body fat: High estrogen levels can interfere with the body’s ability to burn fat, leading to increased body fat.†
Decreased muscle mass: High estrogen levels can interfere with muscle development and cause a decrease in muscle mass.†
Fatigue: High estrogen levels can cause fatigue and a general lack of energy.†
Mood changes: High estrogen levels can cause mood swings, anxiety, and depression.†

Arimistane VS DIM:(5,6,7)

These are two popular anti-estrogen supplements with different mechanisms of action.

Arimistane is an aromatase inhibitor that works by inhibiting the conversion of testosterone to estrogen. By reducing the amount of estrogen in the body, Arimistane can help increase testosterone levels, reduce body fat, and improve muscle mass. It’s commonly used by bodybuilders and athletes to enhance performance and improve body composition.

On the other hand, DIM is a natural supplement that promotes the metabolism of estrogen in the body. Specifically, DIM helps to convert estrogen into less potent forms, which can help reduce the effects of estrogen on the body. DIM is commonly used to alleviate symptoms of estrogen dominance, such as mood swings, irregular periods, and breast tenderness.

While both Arimistane and DIM can be effective at reducing the effects of estrogen in the body, they have different mechanisms of action and are often used for different purposes. Arimistane is typically used by individuals seeking to enhance performance and improve body composition, while DIM is more commonly used by women experiencing symptoms of estrogen dominance. Additionally, DIM does not raise testosterone and may not block the conversion of testosterone to estradiol. In contrast, AIs like armistice may increase serum levels of testosterone. (5,6,7)

Arimistane VS DIM

Popular Products:

Several types of anti-estrogen supplements are available for men, each with its unique mechanism of action and intended purposes.

Here are some of the ingredients to look out for:

Arimistane: Arimistane, also known as androst-3,5-dien-7,17-dione, is a popular anti-estrogen supplement that inhibits the conversion of testosterone to estrogen. It is a potent aromatase inhibitor that has been shown to be effective in reducing estrogen levels and increasing testosterone levels.†
DIM: DIM, short for diindolylmethane, is a naturally occurring compound found in cruciferous vegetables such as broccoli and cauliflower. It works by promoting the conversion of estrogen into a less potent form, which can help reduce the overall estrogen burden in the body. It is also believed to have anti-cancer properties and other health benefits.†
Calcium D-Glucarate: Calcium D-Glucarate is a supplement that promotes the excretion of estrogen from the body. It is particularly useful for men with high estrogen levels due to environmental factors or exposure to toxins.†
Resveratrol: Resveratrol is a powerful antioxidant found in red wine and grapes that has been shown to have anti-estrogenic effects. It works by inhibiting the activity of the aromatase enzyme, which can help reduce the conversion of testosterone to estrogen.†
Zinc: This essential mineral plays a key role in testosterone production and can also help regulate estrogen levels. It works by inhibiting the activity of the aromatase enzyme, which can help reduce the conversion of testosterone to estrogen.†
Chrysin: Also known as 5,7-dihydroxyflavone, Chrysin is a naturally occurring flavonoid found in many plants, including passionflower, honey, and propolis. Chrysin is believed to work by inhibiting the activity of the aromatase enzyme, which can help reduce the conversion of testosterone to estrogen. However, research on the effectiveness of chrysin as an aromatase inhibitor is mixed.†

In this section, we’re going to introduce some of our popular estrogen blocker supplements and their formulas!

Hi-Tech Pharmaceuticals Arimistane
Force Factor DIM
Blackstone Labs Eradicate
REPP Sports Arimivar
LG Sciences Form XT

But these aren’t the only great options available. You can view other products on our website.

Hi-Tech Pharmaceuticals Arimistane:

Our first estrogen blocker product is Arimistane® by Hi-Tech Pharmaceuticals. It features 50mg per tablet and has Hi-Tech Pharmaceutical’s signature Cyclosome Delivery™ system. This may improve the delivery and absorption of this product.†

Androsta-3,5-dien-7, 17-dione:

Androsta-3,5-dien-7, 17-dione is a metabolite of 7-Keto DHEA. This ingredient assists with binding to the aromatase enzyme and preventing the conversion of testosterone to estradiol. In return, you may experience an increase in energy, sex drive, and a decrease in fat storage.†

How To Take Hi-Tech Pharmaceuticals Arimistane Estrogen Blocker:

The manufacturer recommends taking one (1) tablet in the morning and one (1) tablet in the evening. Do not exceed two (2) tablets daily.

Customer Review By Lou: “I’ve been using this product on cycle and I have noticed some slight changes in just a few weeks. I like this product because it has a high dosage of Arimistane, and it has done wonders for me. I gained 8lbs in muscle mass and I can’t help but to think this product aided me along the way. Will continue to order!”

Force Factor DIM:

Next, we have Force Factor’s DIM. Similar to Arimistane®, DIM is the main active ingredient in this product. However, DIM generally is taken during PCTs or in a testosterone booster blend. To support the delivery and absorption, Force Factor’s DIM also features Black Pepper Fruit Extract.

DIM:

DIM is a phytochemical found in cruciferous vegetables like broccoli. This ingredient is often in studies for its anti-androgen and anti-cancer properties. But DIM is unlikely to raise testosterone. On the other hand, though, it may support testosterone effects and estrogen metabolism. (5,8)

BioPerine®:

The other ingredient in this formula is Bioperine®. This ingredient may help increase the bioavailability and absorption of the other ingredients within a formula. (9)

How To Take Force Factor DIM:

The manufacturer recommends taking one (1) capsule daily with a meal.

Customer Review By Andy: “I was on the fence about this product at first. Heard some good reviews and thought I would give it a try. I’m glad I did. I wasn’t expecting to notice changes so fast (first 2 weeks) but some things I noticed was my natural energy levels being higher, sleeping better, and even having fresher looking skin. Overall I think this product could be beneficial to many people.”

Blackstone Labs Eradicate:

Following Force Factor’s DIM, we have our first blend estrogen blocker, Blackstone Lab’s Eradicate. This estrogen blocker features N-Acetyl L-Cysteine, Safed Musli, and Arimistane. Compared to Hi-Tech Pharmaceuticals, Eradicate has half the amount of this ingredient at 25mg per serving. However, the additional ingredients in this formula may also contribute to Eradicate being a potent estrogen blocker and PCT.

N-Acetyl L-Cysteine (NAC):

NAC may assist with prostate support, DHT inhibition, and support healthy liver function. (10)

Safed Musli:

The last ingredient in this formula may be beneficial for its properties as an aphrodisiac, adaptogen, and potent antioxidant. (11,12)

How To Take Blackstone Lab’s Eradicate:

The manufacturer recommends taking one (1) capsule 1-3 times daily with food. Do not exceed four (4) capsules in 24 hours. Due to the extreme potency of Eradicate, do not use it for longer than eight (8) weeks without a four (4) week off period.

Customer Review By Al: “This product does the job. Haven’t experienced any estrogenic side effects post cycle. I used Eradicate before and feel its better to start taking it prior to the end actual end of your cycle. This way you can avoid issues before they can start.”

REPP Sports Arimivar:

The next product is Repp Sports Arimivar, which features four active ingredients. Of these four ingredients, two are shared with Force Factor’s DIM:

DIM
Black Pepper Extract

In this comparison, Force Factor’s DIM has a higher volume of DIM by 100mg. But like Eradicate, Arimivar has other ingredients that make this a great option for anti-estrogen support.

Chrysin:

Chrysin is a flavonoid that may increase androgen production and inhibit the enzyme aromatase, which converts testosterone into estradiol. (13)

Grape Seed Extract:

Grape Seed Extract may support cardiovascular health and may exhibit aromatase inhibition. (14,15)

How To Take REPP Sport’s Arimivar:

The manufacturer recommends taking 1 serving (2 capsules) of Arimivar with water once daily.

Customer Review By Yammily: “I like that this product delivers on what it is saying it does~ it does take a couple weeks for it to kick in.”

LG Sciences Form XT:

Our final estrogen blocker is Form-XT from LG Sciences, which features three active ingredients, including arimistane. However, Form-XT features the least amount of this ingredient compared to Eradicate and Arimistane®. In addition to this, Form-XT also features resveratrol and epicatechin.

Resveratrol:

Resveratrol compares most closely to Chrysin as these ingredients may contribute to aromatase inhibition with natural anti-aromatase activity. (16)

Epicatechin:

Similarly, epicatechin may inhibit estradiol and progesterone production. But, more research is necessary to validate these effects. (17)

How To Take LG Science’s Form XT:

The manufacturer recommends taking three (3) tablets per day in divided doses with or without food. Do not exceed 6 tablets per day.

Customer Review By Nicolas: “I’ve been taking this after a cycle of 1-Testosterone, so far so good. Will continue to take!”

Which Should You Try:

When deciding which anti-estrogen product you take, where you’re starting from. If you are coming off a prohormone cycle that has risks of estrogen conversion, you may want to choose a higher dosage AI product. Products like Hi-Tech Pharmaceutical’s Arimistane® may be a good option for this. However, if you’re looking for an anti-estrogen product as a way to promote free testosterone levels indirectly, you may benefit from a blend like Blackstone Lab’s Eradicate or LG Science Form-XT.†

However, if you want to reduce estrogen without altering testosterone levels, Force Factor DIM may be a better option for you. For a better balance between reducing estrogen and naturally boosting testosterone, Arimivar from Repp Sports may be the best option for you.

Anti-Estrogen FAQs:

In this section, we’ll be diving into some of your most frequently asked questions about estrogen blockers!

Are Estrogen Blockers Legal?
Yes! Estrogen blockers like the ones we mentioned in this post are readily available. However, these products may be banned by some sports organizations and/or increase the risk of false positives on a drug test. If this concerns you, we recommend contacting your sports organization or physician before taking any estrogen blocker. †
Are Anti-Estrogen Supplements Safe For Women?
Hormone therapy is a common treatment option for many women’s health issues. However, the abovementioned products do not specifically state they are safe for women. Therefore, we would advise women interested in taking an estrogen blocker to consult a physician first. †
Can Estrogen Blockers Help Weight Loss?
Estrogen blockers may have some potential to help with weight loss, particularly in men and women who have high levels of estrogen in their bodies. High levels of estrogen in men can interfere with muscle development and cause an increase in body fat, while high levels of estrogen in women can lead to an increase in body fat and difficulty losing weight.† By blocking the effects of estrogen or reducing the amount in the body, estrogen blockers may help reduce body fat and promote weight loss. Some studies have suggested that estrogen blockers can help reduce body fat and improve body composition, particularly in individuals who are overweight or obese. However, these products are not directly for weight loss, so we wouldn’t recommend that users take an estrogen blocker solely. †
Can Estrogen Blockers Cause Joint Pain?
Estrogen blockers can potentially cause joint pain as a side effect, although this is not a common side effect and may occur only in some individuals. Joint pain is more commonly associated with the use of aromatase inhibitors. Aromatase inhibitors can reduce the amount of estrogen in the body, which can cause joint pain and stiffness in some individuals. This is because estrogen plays a role in maintaining healthy joints by reducing inflammation and promoting the production of joint lubrication. However, regular exercise and weight loss may assist with joint pain and stiffness relief. (18)
What Is The Difference Between Estrogen Blockers VS Testosterone Boosters?
Estrogen blockers and testosterone boosters are two different types of supplements with different mechanisms of action and intended purposes. Estrogen blockers work by reducing the amount of estrogen in the body or blocking the effects of estrogen on the body. This can be beneficial for men who have high levels of estrogen, which can interfere with muscle development, cause an increase in body fat, and lead to a variety of other symptoms. Estrogen blockers are often used by bodybuilders and athletes to improve body composition and enhance performance.† Testosterone boosters, on the other hand, work by increasing the amount of testosterone in the body or enhancing the body’s ability to produce testosterone. Testosterone is an important hormone for muscle development, bone density, and overall health. Low testosterone levels can lead to various symptoms, such as reduced muscle mass, decreased libido, and fatigue. Testosterone boosters are often used by men who have low testosterone levels or who are looking to enhance their athletic performance.† While estrogen blockers and testosterone boosters may have some overlap in their effects, they have different mechanisms of action and are intended for different purposes. † Luckily, many options are available for natural testosterone boosters with estrogen blockers, like Arimiplex by Hi-Tech Pharmaceuticals.
