Diindolylmethane (DIM) is a natural compound found in cruciferous vegetables like broccoli, Brussels sprouts, cabbage, cauliflower and kale.
In short, DIM helps you to metabolize and reduce the amount of “bad” estrogen in your body, so you can stay anabolic.
Estrogen is an important hormone for both men and women, provided it’s the right kind. In fact, 2-methoxy and 2-hydroxy estrogens have been shown to offer beneficial effects, such as strong bones, healthy cholesterol levels and libido.
The world is full of chemicals that act like estrogen. Plastics, tap water, canned foods and golf course fertilizers are just a few examples of how these toxic estrogens end up in your body. Plus, things like abdominal fat and alcohol increase the production of even more bad estrogens for your body to manage.
The net result of too many bad estrogens is a hormonal imbalance that leaves you in an unhealthy, catabolic state.
Your body is constantly seeking to maintain the right testosterone to estrogen ratio. DIM supports this effort by helping you metabolize bad estrogens (such as 16 hydroxy estrogen) into its healthier counterparts.
When balance is restored, your body can shift into an optimal state for muscle growth, high performance and fat loss.

  • Helps to metabolize bad estrogens
  • Supports an optimal testosterone to estrogen ratio
  • Aids in the prevention of hormonal imbalances caused by dieting
  • Promotes muscle growth and fat loss

DIM is the activated form of I3C…
What is DIM?
Diindolylmethane (DIM) is a natural condensation product of indole-3-carbinol (I3C), which is found in cruciferous (Brassica family) vegetables such as cauliflower, cabbage, cress, bok choy, broccolikale, and similar green leaf vegetables. Increased dietary intake of this family of foods has been associated with healthy cell growth.
Part of this effect is likely due to DIM’s role in estrogen metabolism balance in the body (see below). There is also preliminary research implicating DIM as an immunomodulating supplement against auto-immune disease, although further research is required.
DIM and I3C
DIM is a natural diindole condensation product of I3C created during digestion in the presence of sufficient stomach acid. This chemical is more shelf-stable and more easily absorbed in the digestive tract than I3C. Recent research has implied that benefits previously attributed to I3C may actually be the result of DIM created through conversion in the digestive tract. Further research is required to confirm these results before attributing all of the beneficial effects of I3C to DIM.
DIM and Estrogen Balance
Both males and females produce estrogen naturally in their bodies, although women produce significantly higher levels. This endogenous estrogen can either be metabolized to 16alpha-hydroxyestrone (16OHE1) or 2-hydroxyestrone (2OHE1). In contrast to 2OHE1, 16OHE1 is highly estrogenic. Research suggests that DIM preferentially promotes the metabolism of estrogen to the less harmful, and less active 2-hydroxyestrone form.
DIM, Male Hormones and Prostate
DIM has been directly studied as an anti-androgen supplement. It has also been found to reduce PSA expression, and act as a strong competitive inhibitor of dihydrotestosterone (DHT), a hormone responsible for many male-associated problems. DIM is likely the first example of a pure androgen receptor blocker extracted from plants.
DIM and Age-Related Muscle Loss in Men
As men age, they naturally produce lowered levels of testosterone and over time estrogen can be found in higher concentrations in their tissues, resulting in a loss of muscle mass. Testosterone is one of the hormones responsible for anabolic muscle growth in the body. There is a natural balance of the conversion of testosterone to estrogen in the body. As noted above, DIM has been shown to regulate the metabolism of estrogen in the body to be less active. This helps to shift the hormonal balance more favourably in men entering andropause (“male menopause“).
How can I take DIM?
DIM can be absorbed directly from eating cruciferous vegetables from the Brassica family, such as cauliflower, cabbage, cress, bok choy, broccoli, kale, and similar green leaf vegetables. It is important that if cooking these vegetables, not to boil them, as it will significantly reduce their beneficial content.
In order to get higher doses, DIM can be supplemented using capsules or combination formulas. When supplementing DIM, it is generally taken at between 100 and 200 mg per day. A dose of 200 mg was found by a preliminary safety study to be the highest dose that did not produce negative side effects in the research group.
Important Information
DIM is considered safe in both food/diet amounts and therapeutic dosages. Excess supplementation may result in skin rashes, increased liver enzymes, as well as nausea and vomiting. Overuse and/or preventative use of DIM is further ill advised because of its hormone altering effects in normal individuals that can result in systemic hormone dysregulation. For this reason, do not use as a supplement while pregnant or breastfeeding.
