The Best Estrogen Blocker For Men 2024 – DIM 3X, Testosil Reviews, Price, Where to buy Estrogen Blocker

As men age, especially past 30 or 40, our once optimal hormonal balance may begin to deteriorate precipitously. That means testosterone levels decline and estrogen levels rise. The best estrogen blocker for men, a 100% natural dietary supplement called DIM 3X, is formulated to help men achieve ideal hormonal levels by reducing harmful estrogen volume and supporting ample testosterone quantities.

Do you find yourself feeling more fatigued these days? Has it become nearly impossible to cut unwanted body fat? Have your moods or general mindset become increasingly negative or unpredictable?

If you’re in your mid to late 30s or older and answered yes to these questions, an average decline in hormonal balance could be taking away from your quality of life. The good news is you don’t need to take these troubling issues lying down. An elite all-natural supplement could help you to feel more energetic, improve your body composition, and enhance your mental fortitude, among other benefits.

In this article, we’ll profile DIM 3X, a highly-respected, American-made, all-natural dietary aid that has been helping men to fight back against hormonal decline for years. Our extensive research shows that DIM 3X is the best estrogen blocker for men, and we’ll give you all the details as to why, but first, we’ll look at how too much estrogen can be devastating for male wellness.

What Does High Estrogen In Men Mean?

A small amount of estrogen is actually necessary for a man’s body to properly execute several physiological processes, including supporting strong cognition, maintaining bone density, and enhancing reproductive efficiency. However, a problematic imbalance can occur as testosterone production decreases and estrogen levels increase.

Two types of estrogen can be found predominantly in men. One’s called estrone, and the other is estradiol. Estradiol is considered the “bad” estrogen for guys because it has more substantial estrogenic effects.

While all forms of estrogen are almost nonexistent in young men, an adult man’s blood will usually contain 10-60 picograms/milliliter of estrone and 10-40 picograms/milliliter of estradiol.

This increased estrogen concentration results from an enzymatic reaction. In said reaction, an enzyme called aromatase takes a portion of testosterone and chemically converts it into estrogen.

Issues might arise as testosterone levels naturally decline because the aromatase enzyme continues to convert the remaining, albeit lessened, testosterone into estrogen, often resulting in a progressively worsening hormonal imbalance.

Effects of Estrogen on the Male Body

The resulting loss of hormonal equilibrium can wreak havoc on the male body, contributing to severely degraded body composition and many other problems. Too much estrogen can make cutting body fat, packing on lean muscle mass, and getting tangible results in the gym incredibly challenging.

Common effects of abundant estrogen on the male body include:

  • Reduced Lean Muscle Mass
  • Increased Body Fat
  • Gynecomastia (Man Boobs)
  • Lowered Bone Density
  • Mood Swings
  • Cognitive Decline

Unfortunately, many of these problems commonly afflict men in their 30s, 40s, 50s, and beyond. Often they’re due in large part to the hormonal degradation that comes with age. Many other factors, such as genetics, body weight, and lifestyle, can also affect outcomes.

The best estrogen blocker for men, DIM 3X, could be a viable option to help many men alleviate those problems.

If you’re considering a new supplement, consult your physician to discuss your options. And note that all-natural health supplements formulated to help balance hormone levels, such as DIM 3X, aren’t designed to remedy severe health difficulties but could provide excellent benefits for those with average hormonal disparities.

Now, it’s time to put DIM 3X under the microscope and show you why so many men have come to love this 100% natural estrogen blocker.

Men may achieve excellent gains, with no known negative side effects, by taking just a single small capsule a day.

DIM 3X is so good at what it does that it has gained the support of medical professionals, including a Certified Doctor of Osteopathic Medicine and former UFC Ringside Physician, Dr. Kaleb Redden. A dedicated Sports Medicine Physician and fitness guru, Dr. Redden wholeheartedly recommends DIM 3X to his patients.

And if a doctor’s recommendation isn’t enough for you, check out what a few verified users had to say:

A verified Amazon buyer said

Decided to try DIM3X recently after discovering and researching into DIM and its effects on the body as we age. I am glad I did, within 1 short week of using the product I already started noticing more energy and stamina in my workouts and overall less slugging in my days.

Another verified Amazon buyer said

Being in my 60s I was looking for something that’d help get more energy. When I learned about the effects of Estrogen, it was a no brainer to buy DIM3X. Glad I did, within only 2 weeks I’m already noticing significant changes.

And these reviews were no outliers. In fact, the vast majority of DIM 3X customer reviews were effusive in their praise of the all-natural estrogen blocker. It appears that men all over the world are experiencing massive life-altering improvements while using this product.

Reports indicate DIM 3X could help men to:

  • Metabolize Estrogen
  • Support Testosterone Production
  • Increase Daily Energy Levels
  • Lower Visible Body Fat
  • Enhance Strength & Stamina
  • Improve Mental Clarity
  • Intensify Libido

These benefits indicate that DIM 3X could deliver superior results for men dealing with average or moderate hormonal issues, which is likely a large portion of the population.

But how can it do that? What makes this estrogen-blocking formula better than the rest?

Let’s get into the mechanics behind DIM 3X that fuel the supplement’s potentially massive potency.

The Enhanced Absorption System

DIM 3X employs a unique absorption-enhancing system to support enhanced nutrient absorption and bioavailability for more outstanding results. The formula incorporates a pair of U.S.-patented compounds, AstraGin and BioPerine, that can significantly improve human nutrient retention.

You see, the human body is a relatively hostile place for the compounds we consume dietarily. Many of the nutrients we ingest are burned up in stomach acid or flushed away by the digestive system. And nutrient retention rates can decline with age or be impacted by factors like weight, diet, and lifestyle.

The patented bioavailability enhancers in DIM 3X are plant extracts that protect the nutrients we consume once they’re inside the body and can increase uptake activity to enhance absorption rates. The presence of these compounds in any health supplement is a clear indication that you’re looking at a quality product.

AstraGin and BioPerine are two of the most highly-respected bioavailability enhancers you’ll find in any all-natural product. With that in mind, let’s break down exactly how these compounds work.


This compound can be found in some breakthrough high-end health supplements and vitamins. It’s built with highly-purified extracts of two roots, Astragalus membranaceus and Panax notoginseng, standardized to provide a significant uptick in nutrient absorption.

AstraGin works to improve the availability of nutrient transporters and reduce inflammation in the gut, resulting in a plethora of benefits.

AstraGin may help to:

  • Boost Nutrient Absorption
  • Support Intestinal Wellness
  • Strengthen Gut Wellness
  • Improve “Good” Gut Bacteria Numbers

By taking a multistep approach to enhance nutrient absorption, along with intestinal and gut wellness, AstraGin can promote the efficiency of a health supplement, vitamin, or other dietary aid. Its presence in DIM 3X is a huge advantage for users looking to achieve better gains in less time.


BioPerine is a purified extract of black pepper containing high concentrations of piperine, the bioactive compound in Piper nigrum. Piperine is known to support enhanced nutrient absorption and boost nutrient bioavailability naturally. BioPerine is standardized to contain 95% piperine in each serving.

This proprietary compound works by helping to inhibit enzymes produced by the liver and intestines that break down some nutrients in the body. A clinical trial found that supplementing with piperine extracts could significantly enhance the bioavailability of some nutrients in humans and animals.[1]

BioPerine May also help to:

  • Improve Thermogenesis
  • Boost Digestion
  • Enhance Blood Flow

Like AstraGin, BioPerine is usually found in elite health supplements and vitamins. The purified black pepper extract can have excellent bioavailability-enhancing effects, effectively improving the efficiency of any dietary product it’s a part of.

AstraGin & BioPerine—An Impressive Duo

While AstraGin and BioPerine can be found by themselves in some of the best health supplements and vitamins, this is the only all-natural product we know of that contains both U.S.-patented bioavailability enhancers.

This unique combination should significantly enhance the bioavailability of the other compounds in DIM 3X with no known negative side effects. It’s safe to say the enhanced absorption system in DIM 3X takes an already excellent product and propels it into the stratosphere.

Helps To Metabolize “Bad” Estrogen

As stated above, two types of estrogen are primarily found in men. One is estrone, with weaker estrogenic effects. The other is estradiol, with more substantial estrogenic effects. DIM 3X is designed to help metabolize “bad” estrogen (estradiol) and convert it into a more usable form of estrogen for men (estrone).

It does so by stimulating the conversion of an estrogen metabolite known as 16-alpha-hydroxyestrone, which has significant estrogenic properties, into another estrogen metabolite, 2-hydroxyestrone, with weaker estrogenic activity.

Estrogen compounds with weaker estrogenic activity can help men perform several physiological processes but don’t come with the multitude of known downsides that estrogen compounds with stronger estrogenic activity bring for men.

As a result of this conversion, DIM 3X users may experience:

  • Greater Hormonal Balance
  • Improved Bone Wellness
  • Enhanced Metabolic Efficiency
  • Boosted Body Composition
  • Stronger Reproductive Efficiency

Unlike many estrogen blockers that only block the production of estrogen, DIM 3X supplies the added benefit of aiding in converting the estrogen that’s more harmful to a man’s wellness into a form of estrogen, which can be productively used in the body. This elite feature is an excellent example of why DIM 3X is the best estrogen blocker for men.

Supports Healthy Testosterone Production

While DIM 3X isn’t a testosterone booster in name, it contains elements that can help support healthy testosterone production. As you know, the relationship between testosterone and estrogen requires balance, but a man should have significantly more testosterone than estrogen to live his best life.

That’s why DIM 3X promotes the secretion of testosterone, primarily through the inclusion of Vitamin E. An essential nutrient highly concentrated in many nuts, seeds, and leafy green vegetables. Vitamin E is a potent antioxidant and anti-inflammatory that can support critical cells responsible for testosterone production.

Optimal testosterone levels can help men to:

  • Add Lean Muscle Mass
  • Burn More Body Fat
  • Improve Libido
  • Boost Mental Wellness
  • Increase Confidence

By metabolizing estrogen DIM 3X helps restore hormonal balance and boost testosterone levels because as estrogen levels lessen, testosterone concentration increases. However, by adding Vitamin E to its formula, DIM 3X could also directly support testosterone production for even more impressive results.

Inhibits Aromatase Enzyme

DIM 3X actively operates to inhibit the production of the aromatase enzyme. If you remember, the aromatase enzyme is the molecule in men that converts testosterone into estrogen. In small amounts, this enzyme plays a role in aspects of wellness. However, in larger amounts, common in older men, it can have alarming consequences.

Despite testosterone levels declining with age, an analogous decline in aromatase production doesn’t occur. Therefore, the aromatase enzyme may continue to convert your lowered volume of testosterone into estrogen, but at the same rate as when testosterone levels were higher.

This enzymatic process is a significant contributor to the typical hormonal decline many men face. Thus, DIM 3X is designed to block the production of aromatase to help maintain the levels of testosterone present in users.

With less aromatase synthesis, men should expect to experience:

  • Greater Daily Energy
  • Improved Focus
  • Better Hormonal Balance
  • Moderate Estrogen Levels
  • Testosterone Protection

By inhibiting the aromatase enzyme, DIM 3X could effectively preserve testosterone levels while lowering estrogen levels. This could promote enhanced hormonal balance for greater overall wellness in the long run.

Ingredient Overview

DIM 3X includes four primary ingredients, two of which assist in facilitating hormonal balance and two of which enhance nutrient absorption rates. This simple but effective formula can bring a wide variety of advantages for users.

DIM (Diindolylmethane)

DIM or diindolylmethane is the primary ingredient in DIM 3X. The bioactive compound in cruciferous vegetables like broccoli, arugula, cauliflower, cabbage, and bok choy, DIM can help men to optimize hormonal balance.

In recent years, DIM has gained attention for its hugely beneficial effects on estrogen control and overall hormone levels.

DIM is believed to aid in:

  • Inhibiting Aromatase
  • Metabolizing “Bad” Estrogen
  • Reducing Estrogen Receptor Activity

And science backs up the use of DIM as an effective estrogen modulator. A clinical trial noted that participants orally supplementing with DIM showed “an increase in the ratio of 2-hydroxyestrones (C-2) to 16α-hydroxyestrone (C-16)” (“good” estrogen to “bad” estrogen) and DIM could “serve as an antiestrogenic dietary supplement”.[2]

DIM 3X uses a clean, purified form of DIM extracted from the finest sources to deliver superior results.

Vitamin E

A potent antioxidant and essential nutrient, Vitamin E can contribute to reducing oxidative stress and enhancing overall wellness. Additionally, it could promote testosterone production and support ideal hormonal balance in men.

Vitamin E could also help to:

  • Boost Skin Quality
  • Enhance Eye Wellness
  • Improve Immune System Efficiency

A landmark study involving both humans and animals concluded that oral supplementation of Vitamin E could significantly enhance testosterone levels in male subjects.[3] Potent antioxidants like Vitamin E can reduce inflammation in many key cells for hormone production, leading to improved hormonal outcomes.

AstaGin & BioPerine

The dynamic duo of U.S.-patented bioavailability enhancers makes up the other two primary ingredients in DIM 3X. These all-natural proprietary compounds could significantly increase the rate at which users absorb both Vitamin E and DIM.

Is it bad to have estrogen as a man?

Small quantities of estrogen are needed for some biological processes to occur efficiently in men. So, some level of estrogen, especially less estrogenic forms of estrogen, like estrone, can offer benefits. However, estrogen can become problematic in older men as testosterone levels decline. This age-related natural decline creates a hormonal imbalance that can negatively affect a man’s wellness.

Who should take DIM 3X?
