If you want to learn what the best estrogen blockers for men are, you’ve come to the right place.
In this article, you’ll discover the evidence-based truth about what estrogen is, why elevated levels of this hormone are problematic, and the best natural anti estrogen supplements available to today.
What is Estrogen?
Estrogen is the primary female sex hormone. It promotes the development and maintenance of female characteristics in the human body.
While estrogen is labeled as the female hormone, men also produce it, although in significantly lower volumes.
Because estrogen has feminizing effects, elevated levels of this hormone in males can cause symptoms such as the development of breasts, loss of muscle mass, emotional disturbances, fatigue, and abdominal fat gain. (1)
Many of these symptoms are the same as those caused by low testosterone levels. That’s because estrogen and testosterone bind to the same androgen receptors in the body.
In other words, if you have higher estrogen levels, testosterone produces less of its beneficial effects, such as aiding muscle growth, supporting fat burning, supporting mental well-being, and making you feel like a man.
The Harmful Effects of High Estrogen in Men
There are various reasons that elevated estrogen levels are problematic for men. These include that high estrogen:
- impairs testosterone production by suppressing the release of the luteinizing hormone.(2)
- causes feminine sex characteristics, such as gynecomastia, the formation of breast tissue in men. (3)
- stimulates the formation of body fat, which not only impairs your appearance, but also enhances your estrogen levels by stimulating the aromatization process. (4)
- increases serotonin and lowers the thyroid hormone, causing a reduction in metabolic rate. This makes you more prone to fat gain and makes it harder to lose excess pounds.
- can cause erectile dysfunction, both by lowering testosterone levels and by increasing prolactin levels. It basically leads to a reduction in dopamine, a key neurotransmitter for strong erections. (5)
Among all these harmful effects of elevated estrogen levels, there’s only one real benefit of this hormone in the male body, which is that estrogen supports bone health.
Research links higher estrogen levels to stronger bones. That’s one of the reasons post-menopausal women are more prone to osteoporosis and to breaking bones – owing to reduced estrogen levels.
What’s more, men who use powerful estrogen blockers such as Tamoxifen anti estrogen tablets in high dosages often experience joint achiness and are more likely to break bones.
However, even if you supplement with high dosages of over-the-counter estrogen blockers, it’s debatable whether a reduction in estrogen causes the bone-weakening effects.
Instead, some research suggests that it’s not estrogen but rather the hormone progesterone that’s responsible for aiding bone strength and preventing osteoporosis. (6)
Besides, you generally don’t have to worry about the weakening of bones if you are bodybuilding or work out hard in the gym. That’s because lifting weights is one of the best things you can do to obtain and maintain strong bones. (7)
Therefore, if you’re a man, and especially if you’re one who wants to shape an eye-catching figure and optimize his sexual performance, you’ll likely benefit from reducing your estrogen levels.
Ranking The Best Estrogen Blockers of 2019
What follows are the nine best estrogen blockers in our opinion that are available right now. They’re all based on scientifically proven ingredients so that you can rest assured that you’ll reap the estrogen-lowering benefits.
1. Testogen (Editors Choice)
When it comes to estrogen blockers, Testogen is the best pick. That’s because the product contains an extensive spectrum of nutrients – in the right dosage! – that are proven to lower estrogen.
What’s more, the ingredients are carefully selected to enhance testosterone levels, which means you’ll get the best of both worlds – higher testosterone and lower estrogen.
One of the compounds found in Testogen is Boron. One study on males found that supplementing with 10 mg of boron per day for seven days reduced estrogen by 39% and increased free testosterone by 28%.(8)
Other proven and tested ingredients found in Testogen are piperine, zinc, Vitamin B6, red ginseng extract, fenugreek extract, d-aspartic acid, Vitamin K1, nettle leaf extract, Vitamin D, and magnesium.
Best of all? The manufacturers of Testogen are so confident that their product will do magic for your hormonal health that they back their product with a 100% satisfaction guarantee.
So, you can try the product risk-free and judge for yourself. If you’re not satisfied, you’ll get your money back. That’s why we especially recommend Testogen to those who’ve never used an testosterone booster or estrogen blocker before.
Prime Male is another excellent all-rounder when it comes to lowering estrogen and boosting testosterone. It contains a wide range of proven ingredients, including:
- D-aspartic acid calcium chelate, which triggers the release of luteinizing hormone (LH). This, in turn, stimulates the testes to produce more testosterone.
- Boron, which, as already mentioned, is a powerful mineral for boosting testosterone, DHT, and lowering estrogen.
- Mucuna pruriens, which boosts the release of LH from the pituitary gland, leading to higher testosterone levels. Additionally, animal research shows that this compound helps to battle high estrogen.(9)(10)
- Korean red ginseng extract, a compound that has been used for centuries to boost energy levels, strengthen the immune system, increase longevity, and enhance hormonal health and libido.
- Many more ingredients, such as BioPerine, luteolin, magnesium citrate, nettle root extract, vitamin B6, vitamin D, vitamin K2, and zinc.
In other words, you can’t go wrong with PrimeMale. The only minor downside, however, is that the product doesn’t contain indole-3-carbinol (IC3) or diindolylmethane (DIM), but you could supplement these individually.
AndroSurge is a potent estrogen blocker for men. What sets this product apart is that it contains Rhodiola root extract, an adaptogen that balances high cortisol.
Since high cortisol levels reduce testosterone and increase estrogen, it’s highly beneficial to add an adaptogen such as Rhodiola to your daily supplementation stack.
Case-in-point: one study found that when healthy men took two grams of Rhodiola extract per day for one month, their testosterone levels increased by an average of 70% compared to those taking a placebo.(11)
Other proven ingredients found in AndroSurge are vitamin D, zinc, grape seed extract, DIM, Eurycoma Longifolia, and BioPerine. No wonder that this product already has over 1,700 raving reviews from customers on Amazon.
Indole-3-carbinol (IC3) is a substance found in cruciferous vegetables like broccoli, cabbage, Brussels sprouts, and kale. It reduces estrogen levels by helping your liver metabolize the hormone more efficiently.(12)
In addition, IC3 also converts potent estrogen molecules into weaker ones, which reduces estrogen levels and leads to a more favorable estradiol-to-estrone ratio.(13)
That’s why IC3 is a fantastic component to reduce estrogen. One study, for instance, found that daily IC3 consumption of 6-7mg/kg significantly increased estrogen clearance via urine in both males and females.(14)
When it comes to supplementing with IC3, you can search for a product that contains this ingredient, such as AndroSurge, which contains DIM, a derivate of IC3. Or, you can supplement with IC3 directly.
Regarding the best IC3 product, we recommend the one by Solaray. It’s a clean, high-potency product derived from a wide range of vegetables, including broccoli, Brussels sprouts, cabbage, cauliflower, and kale.
Estrotase is an estrogen blocker and aromatase inhibitor packed with proven and high-quality ingredients. What we particularly like about Estrotase is that it contains DIM. That ingredient is well-established to be effective at lowering estrogen.
Besides, Estrotase – contrary to many estrogen blockers on the market – is an all-natural formula. That means you won’t have to consume synthetic ingredients that may have estrogenic side-effects.
Here’s the ingredient list of Estrotase:
- Zinc (as zinc ascorbate)
- Maca root
- Tongkat Ali
- Grape seed extract
- Kudzu root
- Gelatin capsules
- Magnesium Stearate
The downside of this product, however, is that it only contains a ten-day supply. Thus, you’ll need around three bottles per month, which makes this option fairly expensive.
This product contains three active ingredients:
- DIM – a derivative of IC3. As already mentioned, IC3 is one of the most efficient natural estrogen blockers available.
- Grape seed extract – a compound (aromatase inhibitor) that’s found in both in vitro and in vivo studies to lower estrogen synthesis by inhibiting the aromatase enzyme. In other words: less estrogen.
- BioPerine – this compound doesn’t lower estrogen levels by itself. However, it does increase the absorption of the other ingredients found in Genius Estrogen Balance. As a result, you’ll receive more of the benefits.
Now, since this product contains only three active ingredients, it may appear less impressive than the other outlined products. But don’t let the minimalist approach fool you!
DIM and grape seed extract are two of the most potent estrogen blockers available. Plus, Genius Estrogen Balance contains these compounds in the proper dosages. That’s what makes this product an excellent choice.
In fact, if you tend to suffer allergies or digestive troubles, it’s best to go for a minimalistic approach since that’ll reduce the likelihood you’ll suffer any negative reactions.
Next up is Estrodex, a supplement designed for bodybuilders who need a post-cycle supplement to restore their hormones.
It contains calcium D-glucarate, Urtica Dioica, indole-3-carinol, and 3,5,4′ TriHydroxy-Transstibene, all of which are proven to be effective at lowering estrogen, increasing testosterone, or both.
The downside of this product is that if you take the recommended dosage of three pills twice per day, each bottle will last only fifteen days. That makes this product expensive. ($0.77 / serving.)
Like most of the products we’ve covered, Anablox Xtreme offers a wide range of potent ingredients. These include:
- Fenugreek extract
- Cissus Quadrangularis
- Tongkat Ali
The downside, however, is that many of these ingredients come in the form of a proprietary blend, whih means we don’t know the exact dosages of each ingredient.
Still, there’s one thing that makes this product unique – it contains milk thistle, a herb that supports liver functioning. That’s why this is an excellent estrogen blocker for steroid users, especially those who use oral steroids since taking those is especially hard on the liver.
Last but not least is TestoFuel. If you’ve been following AnabolicBodies for a while, then you know we’re a fan of this product. That’s because it not only lowers estrogen, it is also one of the best testosterone boosters.
The active ingredients found in TestoFuel are d-aspartic acid, vitamin D, oyster extract, ginseng, fenugreek, magnesium, vitamin B6, vitamin K2, and zinc.
Best of all? The ingredients are present in the right quantities. Plus, the manufacturers use high-quality and highly bioavailable nutrients so that you can reap the most benefits.
Another benefit of TestoFuel over most estrogen blockers, especially those found on Amazon, is that the manufacturers of this product ship worldwide.
The company is based both in the USA and UK, so no matter where you live, you’ll receive the product relatively quickly.
How to Use Estrogen Blocker Effectively
There are two main things you can do to get the most out of your estrogen blockers.
First, take the supplement before you go to bed. That’s beneficial because estrogen naturally increases before you go to sleep. As a result, consuming an estrogen blocker before sleep causes the most significant reduction.
Second, cycle your estrogen blockers by alternating between various products. For instance, take product one on Monday, product two on Tuesday, product three on Wednesday, and then repeat the cycle.
Cycling like this is beneficial because it prevents your body from developing resistance to particular compounds. (Such adaptations don’t tend to be a problem for vitamins and minerals, but for herbs they often are.)
What’s important, however, is that the products you cycle overlap minimally in ingredients. So, use a product that contains different active ingredients at each part of the cycle.
These products contain different ingredients, which prevents your body from adapting to them.
- The Most Potent Testosterone Booster Supplements
- Most Effective Supplements For Muscle Growth
- Steroids Alternatives That Mimic The Effects Of Real Steroids
- Best HGH Supplements
Bottom Line and The Best Estrogen Blocker to Buy
Elevated estrogen levels in men can have catastrophic consequences. These include erectile dysfunction, mood swings, depression, reduced muscle mass, increased body fat, and breast tissue growth.
Fortunately, estrogen blockers can offer a solution. Such products are designed to help you reduce estrogen so that you can improve your health, sexual performance, mental well-being, and body composition.
The best estrogen blocker and testosterone booster on the market in our opinion is Testogen. It contains a wide range of scientifically proven ingredients, such as boron, red ginseng extract, fenugreek extract, d-aspartic acid, nettle leaf extract, and more.
