Diindolylmethane and Testosterone

how DIM affects testosterone

Sometimes on the internet, particularly when you are reading food blogs, they have an old adage that “if you can’t pronounce it, don’t eat it.” I’ve never subscribed to that line of thinking. It is way too simplistic.

And what if you refer to something as its chemical name? I remember someone trolling a food blogger one time, warning that certain foods contained “dihydrogen monoxide”. It caused a furor, all unjustified. They were talking about water, H2O.

In any case, what I’m getting at is even if there’s something on the label of a food or supplement that you don’t recognize, that doesn’t necessarily mean it’s a harmful chemical. Diindolylmethane (DIM) is one such item you will find on a testosterone booster, and it is one powerful ingredient.

What is Diindolylmethane (DIM)?

When it comes to testosterone boosting supplements, what you think you are getting is just that – a formula that increases the amount of this hormone in your body. However, not all ingredients go towards that cause.

In everyone’s body, there is testosterone and estrogen. Testosterone is a male hormone, while estrogen is feminine. Despite these gendered terms, both are found in both sexes. The difference between men and women is the balance between these two hormones.

This is where DIM comes into play and why it is great for t-boosting supplements. Rather than raise your t-levels, it inhibits the formation of excess estrogen. Not only does it slow down the production of estrogens, but it also can convert the more potent forms of estrogen into less potent forms.

Through the consumption of DIM in your diet or with supplementation, men can maintain a proper balance of these two hormones.

While it will not block all xenoestrogens in the body, getting a daily dose of 100 to 200 mg per day can do wonders for male health. 

food sources of diindolylmethane

This amount can easily be obtained through one to two capsules of a t-boosting supplement that contains this ingredient.

As for food sources, you can find DIM prevalent in the following foods, most of which are cruciferous vegetables:

  • Cauliflower
  • Cabbage
  • Brussels Sprouts
  • Broccoli
  • Kale
  • Collard Greens
  • Mustard Greens
  • Watercress
  • Kohlrabi
  • Radish
  • Turnips
  • Rutabaga

Supplements with DIM


I am surprised that I don’t see this ingredient used more often in testosterone boosters. I review many different brands of test boosters on this page here, though the only one that comes to mind right away that contains this ingredient is EVL Test. I speak very highly of this brand in my EVL Test review and encourage you to check this supplement out if you are an adult male who may be suffering from low t-levels.

Can Tongkat Ali Boost Testosterone?

why Tongkat Ali is used in testosterone boosters

When looking at the label of my bottle of Spartagen XT testosterone booster, one name stuck out at me: Tongkat Ali. I just love the name of it. It sounds like a professional wrestler or something.

Curious about what this ingredient is and what it does, and why it is used in the formula for this muscle-building and libido boosting supplement, I did some research to see what it is all about.

Tongkat Ali and Testosterone

This ingredient is a native herb that is found in parts of Southeast Asia and is scientifically known as Eurycoma Longifolia Jack. That’s a mouthful, so let’s just keep calling it Tongkat Ali from here forward.

Traditionally, it has been used in eastern medicine as an aphrodisiac, which is probably why it has use in a testosterone booster. One aspect of any good t-booster is that it increases virility, sex drive, and sexual function in men. Most often, this is because the ingredients increase circulation, which enhances blood flow all over the body – including the intimate areas.

How Tongkat Affects Testosterone

Curious if it is just used for its sexual enhancement properties, or if there is more to it, I pulled up some studies that examined this herb’s effect on the body. In one particular study conducted in 2012, men who were afflicted with late-onset hypogonadism were administered a daily supplement of 200 mg of Tongkat Ali for one month.

At the beginning of the study, around 35% of the test subjects had testosterone levels that were deemed to be in a normal range. At the conclusion of the study, with one month of Tongkat Ali supplementation, that number rose to nearly 91%.

In other research, studies were conducted on 25 men and women in the age range of 57-72.

Their age is particularly of note, as men’s production of testosterone slows down as they age. All participants were physically active and had normal levels of testosterone for their personal characteristics. They were all given 400 mg of Tongkat Ali supplementation for five weeks. At the end of the study, the men were recorded to have an increase of over 60% in free testosterone levels. The women’s results showed an even higher increase of 122%!

These two studies provide evidence that this herb can have drastic results on testosterone levels in both men and women. It leaves no question as to why it is included in many t-boosting formulas. With higher t-levels, muscles can grow bigger and stronger due to less fatigue and quicker recovery time. Not to mention the vitality and energy boost this hormone provides!

On top of its benefits for testosterone levels, ancient medicine was on to something with using this as an aphrodisiac. In one study of men given this supplement for twelve weeks, the participants showed an average increase of nearly 20% in sperm count. In addition, sperm quality also increased by over 40%. Lastly, erectile function showed much stronger results at the end of the study as compared to a placebo group.

Testosterone Boosters With Tongkat Ali

I am surprised that I don’t see this ingredient used more prevalently, given the benefits that are described above. For the t-boosters that I review on this site, you can read more about it in my Spartagen XT review here.

Vitamin D3 and Testosterone

the relationship between vitamin d and testosterone

It is important to get enough Vitamin D in your diet (as well as through exposure to the sun), as well as produce enough of the hormone testosterone. But did you know that these two critical components of healthy are interconnected?

It is no surprise that Vitamin D, in the form of Cholecalciferol, is a popular active ingredient in many testosterone boosting supplements (like those reviewed here). I decided to do some research to find the science behind it and why many of the best test-boosting supplements boast about having this as part of their formula.

How Does Vitamin D Boost Testosterone?

Let’s take a step back for a second and talk about the sources of Vitamin D. This is a fat-soluble nutrient that you can find in many food sources, particularly fatty fish like salmon, mackerel, and sardines, as well as in mushrooms. It is also prevalent in dairy foods, as milk is highly fortified with this vitamin.

On top of that, it isn’t called the “sunshine vitamin” for nothing, as our bodies produce it naturally when we are exposed to sunlight. However, as you know, getting too much sun can lead to skin cancer, so if you’re wanting to get more Vitamin D, let’s stick to diet and supplementation instead of unprotected exposure to the sun.

How Vitamin D and Testosterone are Related

One particular study on the relationship between these two biomarkers was conducted on military members at Fort Bragg, North Carolina – young, active men who rely on physical performance to do their jobs well. It was measured that these men had a high concentration of Vitamin D in their bodies, as well as a high level of total testosterone, indicating a link between the two.

how does vitamin d help boost testosterone?

Another study was performed on a group of over 650 Korean men where all sorts of biometrics were measured. It was found that those who had a high level of measured testosterone, on average had 15% more of Vitamin D in their bodies than those with lower testosterone levels.

While it is unclear in the role that Vitamin D plays in testosterone production, or maintaining a proper level for hormonal balance, evidence suggests that these two clearly have a positive correlation.

However, a further study provided a hypothesis that is similar to that of testosterone and zinc, as well as magnesium and testosterone. It is suggested that supplementing with Vitamin D will be beneficial if there is a general deficiency in this vitamin. However, if levels are already sufficient already, not much benefit is gained.

Supplements Containing Vitamin D

If you feel that perhaps your physical performance or sluggishness is due to a deficiency of Vitamin D, there are many testosterone boosting supplements that contain this essential vitamin. It is a common ingredient among many of the top-selling t-boosters on the market, which I review on this site and can be found linked below:

Magnesium and Testosterone

does magnesium boost testosterone?

When you see marketing for testosterone boosters, you see them boast about the inclusion of magnesium in their formula. There is no doubt that this is a vital mineral for overall body health, but is it worthy of all the hype in the muscle-building supplement arena? I decided to take a look at what research says and find out its role in testosterone boosters to see if it lives up to the marketing claims.

Does Magnesium Help With Testosterone?

Testosterone is an important hormone in men that helps keep virility, energy levels, boosts your mood, and supports muscle growth and bone strength. So where does magnesium come into play in a t-boosting supplement?

Many of the marketing material you see for the top t-boosters is that magnesium is a natural way to kickstart your body’s processes whereby testosterone is produced. Since it is a natural mineral, found in many food sources and readily available, it is deemed a safe way to reinforce hormone production. But does it do anything for your t-levels?

What Research Says

There are very few studies done on the effect of magnesium and t-levels, so I don’t have a lot to go on. However, the research that I did find is not terribly promising. Of the available studies that I found (such as this one), the results that it produced, in terms of raising the level of testosterone, showed a minimal increase – at least to the point of being statistically insignificant.

how magnesium affects testosterone

One study that is often referred to had test subjects take 10mg of magnesium per kilogram of body weight. Their results were tracked against a placebo group. At the end of the study, those who consumed the magnesium supplement showed an increase in free testosterone, however, there were flaws in the testing. With no baseline of t-levels prior to the study, it is unknown how much effect magnesium had on the levels of this hormone.

What is most likely happening, many hypothesize, is that magnesium is effective when there is a general deficiency of this mineral to begin with. If you already have a healthy level of magnesium in your diet, then going over and above won’t show any significant results. It is similar to zinc and testosterone in that manner. However, supplementing with magnesium can be of great benefit to correct any deficiency in this mineral.

That’s not to say that there aren’t benefits to getting enough of this mineral in your diet. While it is not directly correlated with testosterone production, it plays a vital role in muscle health, something any athlete or bodybuilder relies on. If you are hitting plateaus in your athletic endeavors, it is worth investigating whether a magnesium deficiency is the cause.

T-Boosters Containing Magnesium

You can find this mineral in many of the best test boosters on the market. I review many of them on this site. Take a look at the links below, all of which are among my top recommendations for testosterone boosting supplements.

Vitamin B6 and Testosterone

how Vitamin B6 boosts testosterone

It is so important to be getting enough vitamins each day, whether it be through diet or supplementation. While you can get many of the crucial vitamins from a testosterone supplement, it is not the same as taking a multivitamin. Every vitamin has an essential function (or functions) in the body, but only a handful of them have an effect on testosterone production.

One such vitamin that plays a key role in testosterone is Vitamin B6, which you can find in popular supplements like Testogen, Prime Male, and TestoFuel. I was curious to what role it plays and how it interacts with your biology, so I did some research and put together my findings below.

How Does Vitamin B6 Affect Testosterone?

Also known as Pyridoxine, Vitamin B6 is a nutrient that our bodies do not store for any amount of time. The moment that it is consumed, it is utilized for various functions and depleted. This is why it is important to constantly feed our bodies with this essential vitamin.

Some of the functions that this vitamin supports include forming haemoglobin in our blood, which carries oxygen through the bloodstream and helps to fight antibodies that can cause infection or illness. It also plays a role in the regulation of insulin, amino acids, and neurotransmitters that send signals from our brain to the rest of the body.

Vitamin B6 Role in Testosterone Production

Pyridoxine both directly and indirectly has an effect on our t-levels. In a direct way, it stimulates the production of androgens, which results in a rise in testosterone hormone production. In an indirect way, it increases the efficiency of the C2 pathway in the brain. This pathway controls the creation of hormones that have a negative effect on testosterone levels, such as estrogen. Which these detrimental hormones kept in check, it allows a proper balance of testosterone in the body.

vitamin b6 and its role in testosterone production

It can be confusing when you hear of estrogen as a “female hormone”, as it is present in both men and women. The difference in the sexes is the balance of these hormones. In men, there is a higher level of testosterone and vice versa in women. Getting enough B6 in your diet, for men, can keep testosterone at a healthy level.

In addition to regulating the amount of estrogen, it can also control the level of prolactin (according to this study), another detrimental hormone in regards to testosterone. This hormone is what is responsible for men getting too much weight in their chest area, a.ka. getting “man boobs”. That is why you'll also find this vitamin in Zotrim diet pills.

Food Sources of Vitamin B6

If you want more B6 in your diet, eat more of these foods:

  • Fish
  • Pork
  • Poultry
  • Bread
  • Oatmeal and Whole Grain Cereals
  • Vegetables
  • Eggs
  • Peanuts
  • Soy Beans
  • Potatoes
  • Milk

T-Boosters With Vitamin B6

Given the many benefits of this vitamin in regards to testosterone production and suppression of negative hormones, it is important to find a t-booster that contains this ingredient. You can find it some of the top t-boosters I review on this site, linked below:

Vitamin B6 as a Supplement

If you want to take it as a standalone supplement, there are many options on Amazon, as found below.

Testosterone and Zinc

the role of zinc in a t-booster

I’ve talked about the use of zinc in diet pills in another post on this site, but beyond being a great additive to dietary supplements, it also has popular use in many of the top testosterone boosters on the market today.

In fact, if you take a look at my recommended t-boosters, you will find this ingredient in many of the best ones: Testogen, Prime Male, and EVL Test just to name a few.

So what is it about this mineral that makes it such an important part of this hormonal supplement? I took a closer look and present my findings below.

Can Zinc Boost Testosterone?

I’ll back up for a second and describe what testosterone is and why it is important. It is a hormone that plays a crucial part in male health, supporting everything from sex drive and libido, to muscle growth and bone strength. While this hormone is produced naturally in the testes, the male body begins to slow down production as men enter adulthood. When that occurs, it is important to boost the t-levels with a supplement.

What Does Zinc Do?

When it comes to a testosterone supplement, it is not very clear what role zinc plays. Zinc is a crucial dietary mineral for so many different bodily functions and processes, and having a zinc deficiency can lead to many health issues.

This mineral helps strengthen the immune system. It also helps in the breakdown of food and nutrients, the main reason why it plays a key role in many diet pills.

how zinc boosts testosterone levels

As for muscle-building supplements, it can boost the enzymes that produce protein in our bodies.

While it can be found in foods, it is often not ingested in a large enough amount to get a recommended daily value of this key mineral. That’s where supplementation comes into play. As for how it works in a testosterone supplement, research is not definitive in its role. However, studies have indicated that regular supplementation of zinc (30 milligrams daily) increased the amount of free testosterone in their bodies.

As for speculation on why this occurs, many hypothesize that it interacts with the cells in the testicles that are responsible for producing testosterone hormones. However, further research indicated that it had no effect on men who were already getting enough zinc in their diet. Rather, it is useful to supplement with zinc if you have a deficiency, but there is a point of diminishing returns. If you are already getting enough zinc, going over and above a certain amount will have no further benefit.

Food Sources of Zinc

To get more zinc naturally in your diet, you can add some of these foods with regularity:

  • Beef
  • Crab
  • Oysters
  • Chicken
  • Beans
  • Yogurt
  • Oatmeal
  • Pork
  • Nuts

Testosterone Boosters With Zinc

As mentioned above, you will find this ingredient in many of the best-selling t-boosters. You can find this mineral in the following products that I have reviewed:
