What are the best estrogen blockers?
Estrogen blockers are much like testosterone boosters, although they specifically counter the effects of estrogen by blocking the primary female sex hormone.
While estrogen is a natural hormone in both males and females, sometimes the body makes too much estrogen, which can cause adverse effects, especially in men.
Estrogen blockers aim to limit estrogen levels, as high amounts of estrogen can lead to fat gain and muscle loss. Estrogen may impact libido and sexual potency for men too.
The main benefit of estrogen blockers is that these supplements help maintain strength and support better athletic performance to help you smash your training goals.
We wanted to make it easier to find the best estrogen blocker for men, so we put together this comprehensive list of the top natural estrogen blockers available today.

FAQs About Estrogen Blockers
To make it even easier to buy the best estrogen blockers, we’ve put together a handy list of the most frequently asked questions about natural estrogen blockers.
Q: What Do Estrogen Blockers Do?
Estrogen blockers are supplements that block the body’s estrogen production.
While estrogen is important for healthy body functions, a lot of people experience excess estrogen.
This is a common problem for males who may have side effects like water retention, insomnia, increased body fat, and loss of muscle mass if they have too much estrogen.
Estrogen supplements prohibit the conversion of testosterone into estrogen to help maintain a healthy hormonal balance and encourage natural strength and stamina.
While estrogen blocker supplements are used for athletic performance and male sexual health, it’s worth mentioning that estrogen blockers may prevent the growth of cancer cells and are used as a treatment for breast cancer.
Q: What Are the Benefits of Estrogen Blockers?
Estrogen is a natural hormone critical to female development and reproductive functions, but men have estrogen too.
However, there are adverse effects for people who have too much estrogen, and many men may experience muscle loss or low libido if they have excess estrogen.
That’s where natural estrogen blockers come into play, as these supplements prevent estrogen production and encourage higher testosterone levels instead.
The key benefits to look forward to with estrogen blockers include increased strength, greater endurance, and stronger muscle development.
Many supplements offer additional health benefits such as bone and immune protection, depending on the ingredients.
Q: What Are the Side Effects of Estrogen Blockers?
As long as you take estrogen blockers in the recommended dosage, side effects are pretty rare.
However, some people do experience headaches, nausea, or mood swings.
If you feel funny after taking estrogen blockers or you aren’t sure how long to take them, contact your doctor for a professional medical opinion.
Q: Do Estrogen Blockers Increase Testosterone?
Estrogen blockers are designed to increase testosterone, which in turn improves athletic performance, strength training, and overall health.
While estrogen itself is linked to several benefits like increased good HDL cholesterol, having too much estrogen can be detrimental to men and their sexual health.
That’s why many men take estrogen blockers to minimize estrogen and boost testosterone to help them in the gym and beyond.
Q: Do Estrogen Blockers Block All Estrogen?
Estrogen blockers don’t block all estrogen but instead limit its production and block its effects in some cells.
Men with high levels of estrogen may have lower levels of testosterone, and estrogen blockers can provide a better hormonal balance.
These supplements are a healthy, natural way to boost muscle gains and support strong athletic performance for daily workouts.
Q: Which Estrogen Blocker to Choose?
Choosing which brand of estrogen blockers for men depends on your health and fitness goals.
Most people prefer aromatase inhibitors due to their strong natural performance and fewer side effects compared to tamoxifen.
It’s best to look for scientifically proven ingredients like DIM, aspartic acid, grape seed extract, and ginseng, which are all effective at blocking estrogen.
Always check the label before buying an estrogen blocker to see the ingredients and nutritional content.
If you want to boost muscle gains and recovery, look for supplements that provide these benefits.
Also see if the brand is non-GMO, gluten-free, and made in GMP factories.
So long as you are satisfied with the formula, benefits, and serving size, you should be able to notice an exciting difference within a few weeks if not sooner.
