The herbs and foods grouped under this category are not remarkably potent, but their roles are still important, as they can contribute to accessory functions like boosting testosterone or even binding to SHBG and reducing cortisol. These are safe for long term consumption, effective as a precaution to guard against estrogen imbalances, and may be suited for men who just need a little backup in keeping excessive estrogen at bay. Remember, we are all different and some men are more sensitive to estrogen than others, only some men develop “bitch tits” (gyno) etc.
If you’ve ever used a testosterone boosting supplement, chances are it contained this ingredient. It originates from Malaysia, and is also quite popular in male enhancement supplements for its prowess in boosting testosterone. Since natural reduction in testosterone levels begin at about age 30, this supplement could be a perfect aide for rejuvenating sexual aggression along with it’s muscle building potential.
However, that is far from all Tongkat Ali does; studies have shown that it has very good potential as an estrogen blocker, with potency comparable to the prescription SERM Tamoxifen (NOLVADEX ), even though the subjects were mice. Tongkat Ali also binds strongly to SHBG which will increase your free testosterone, but that also means that if your estrogen levels are significantly high, you may exacerbate a scenario of even more free estrogen circulating in blood.
All in all, it serves a better function as a testosterone booster, but there is no reason that is could not be used as a support supplement to stronger natural anti-estrogens.
Another popular natural estrogen blocker, Calcium-D-glucarate is produced naturally by the human body, albeit in small amounts. It is also found in many fruits and veggies and functions similarly in fashion to the way fiber rids the body of cholesterol and estrogen, but CDG also removes toxins and excess estrogen via a chemical process.
During a process known as glucoronidation, lipophilic molecules (such as cholesterol, hormones) are bound to a hydrophilic molecules, which makes them water soluble. Subsequently, it becomes easier to excrete via the kidneys and urine. Though it is useful for reducing estrogen in this regard, it can also promote the excretion of small amounts of testosterone, so keeping an eye on blood levels of both is encouraged.
Interestingly as well is the fact that the higher your exposure to toxins is, so should your intake of CDG be. This is believed to be one of the reasons people that consume an abundantly rich vegetarian diet are less likely to develop cancers. In other words guys, just prep some veggies with that steak and you’ll be all good!
If the name of this compound sounds familiar, it is because it is found naturally in many cruciferous vegetables. It promotes the metabolism of estrogen into less potent forms, exerting a mild boosting of testosterone levels. However, indole-3-carbinol by itself is only mildly potent; it is frequently coupled with other estrogen blockers in cases of high estrogen blood levels.
A child of indole-3-carbinol (since it is a metabolite), DIM works similarly to its parent mentioned above by metabolizing estrogens to less potent forms. Not very potent either, but is useful as an adjuvant to other stronger estrogen blockers, and for its benefits on prostate health (specifically, helping manage BPH). DIM occurs naturally in cruciferous vegetables such as cabbages, broccoli, cauliflower and Brussels sprouts.
In theory, consuming higher amounts of cruciferous vegetables and/or I-3-C or DIM, will make sure your estrogen metabolism works as it should and you can reap the benefits of higher free testosterone. Some broccoli for increased stamina in bed? Sounds like a solid deal.
Zinc is an extremely important, yet severely underused mineral supplement whose benefits extent to all corners of health. For one, it boosts immunity and makes you less susceptible to illness, and is necessary for production of many enzymes along with sperm production in older men.
Of particular interest, however, is its effects on hormone levels. Zinc was shown in studies to reduce the aromatization of testosterone via blocking the aromatase enzyme, and blocking the estrogen receptor (acting as a SERM). This is huge, as there are pharmaceutical drugs that reduce estrogen by specifically doing that, but are notorious for causing side effects which Zinc does not. Unless you frequently eat zinc rich foods such as oysters regularly, food may not suffice as your only source of zinc. Coupled with the fact that we lose zinc in sweat and ejaculatory fluid, the need for zinc in men is significantly higher than for women. So if you get frequent action in the bedroom, topping up with some extra zinc might be a good idea.
Considered “old school” by many, Chrysin has been around a few years and has a reputation as an effective aromatase inhibitor. It occurs naturally and can be found in mushrooms, the passionflower and in chamomile. Studies have shown that chrysin is efficient at inhibiting aromatization in vitro (in test tubes in the lab), leading even the manufacturers of popular pharmaceutical testosterone gels to begin incorporating it in their products. However, there is no actual proof that it acts that way in the human body (in vivo). As such, we cannot in good faith recommend that you use Chrysin as an estrogen blocking supplement, as the effects are likely to go unnoticed, but if you feel like eating your mushrooms have at it!
Resveratrol has been making the rounds in health news for the past couple of years, owed mainly to its claimed anti-aging benefits. However, what is more interesting to us hot blood-blooded young men is its effect on our testosterone and estrogen levels, which are fascinating.
Studies have revealed that resveratrol can significantly boost testosterone levels via various mechanism, such as by increasing conversion of cholesterol into testosterone in the gonads, and suppress the aromatase enzyme at the same time.
The only caveat? Resveratrol by itself is poorly bioavailable in the human body, as the liver rapidly breaks down ingested amounts. There are conjugated forms available however, which are much better equipped to deal with liver breakdown, making them far more efficient (as if you needed a reason to drink more wine!)
Grape Seed Extract
Another sleeper in the making is grape seed extract, classically used for its Procyanidin content which promotes healthier nitric oxide levels. Nitric oxide is important for many body processes, and also improves blood flow through the body, and of particular interest in older men, to that super important body part downstairs!
Besides that, though, is grape seed extract’s ability to block aromatization of testosterone to estrogen. Think that’s a good enough reason to take it? But there’s more, it can also suppress the expression of the aromatase enzyme! What that means is that besides the classic inhibition of the enzyme, your body would make less of that enzyme subsequently.
Less enzyme= less sites for conversion into estrogen!
Targeted Estrogen Blockers
Though the foods and natural sources mentioned above are a great adjuvant for controlling your estrogen levels, if subsequent testing reveals that your levels are still significantly above what they should be, it may be in your best interest to try one of the following as well. Want a good reason to eat more seaweed sushi? Well here you go. You’re welcome.
Arimistane is one of the more potent natural anti-estrogens you can come across, more specifically being a “suicide” aromatase inhibitor. No, that doesn’t mean it will kill you, but what it does mean is that when it binds to aromatase, it does so permanently and will not cause rebound estrogen levels that occur on some strict SERM compounds.
First things first- do not be misled by its “steroid” name, as people get scared when taking anything deemed to be unnatural. Arimistane, however, is natural as natural can be, being produced in your body as a metabolite of the hormone DHEA. Levels of arimistane can be observed in urine if analyzed, proving that it is indeed legit.
Even better news? Arimistane will not attack estrogen with nuclear ambition; rather it will allow decent suppression, but not complete. This is important since when estrogen levels drop too low, joint issues are exacerbated along with bone loss (estrogen promotes bone mineralization).
Eucheuma Cottonii (Edible Seaweed)
As of recently, various varieties of seaweed have made news thanks to their amazing benefits on health. This time, we’re looking at the Edible Seaweed, or Eucheuma Cottonii which shockingly outperformed the prescription SERM Tamoxifen (Nolvadex) in a recent study. Coupled with the fact that its toxicity levels is low, there is a good chance that it is being researched further to treat estrogen dependent cancers as well.
Broussonetia Papyrifera (Paper Mulberry)
Originally from Asia, this tree now grows virtually everywhere and is classified as invasive (sounds like a weed, eh?)
However, that did not stop the results of a study conducted in 2014 which was able to find phenolic compounds in it which possessed estrogen biosynthesis inhibiting properties (or simply aromatase inhibiting properties). The ingredient is now being capitalized on by popular supplement manufacturers, although we can’t deliver a solid verdict as to its efficacy as yet.
Putting It All Together- Changing Your Lifestyle
If there is one thing that needs to be made abundantly clear, it’s the fact that these supplements alone are not magic bullets. They require a conscious effort on your part to change bad habits, and adopt an all-round healthy lifestyle. In other words, time to man up!
Not sure what changes you should be making? No problem! Here are some great starting points:
A comprehensive diet, workout and lifestyle plan, along with consumption of the appropriate supplements can and should improve your testosterone to estrogen profile. Prescription drugs should be avoided, unless absolutely warranted by a specialist endocrinologist. But too many guys are treated with pharmaceuticals as a first line of defense when really the best solution should be a natural one, and teaching guys how to better take care of their bodies. Time to earn back your manhood!
