Do you struggle with unexplained weight gain, PMS symptoms, fatigue, or acne? Have you ever thought it may be related to estrogen dominance? Estrogen dominance happens when the levels of estrogen in your body exceed the level of progesterone. Taking a DIM supplement can help regulate estrogen dominance.

What Is DIM?

One of the supplements used for estrogen dominance is diindolylmethane, or DIM, which is a natural plant-based chemical found in many cruciferous vegetables. The effects of cruciferous vegetables, such as cabbage, broccoli, and Brussels sprouts, are being studied as a treatment for cancer.[1] DIM works to create a healthy balance of estrogen and testosterone in your body and is available in capsules or tablets.

Let’s take a closer look at the benefits of DIM.

DIM Supplement Benefits

  • Anti-cancer properties. DIM may help control or stop cancer cells from forming and spreading, according to research. DIM may be effective specifically in preventing breast or prostate cancer. [6]
  • Viral infection. Human papillomavirus, or HPV, causes multiple disorders, such as cervical cancer or lung cancer. DIM can help reduce the symptoms of HPV and possibly stop the growth of the virus. [3]
  • Estrogen. DIM helps to restore a better ratio of “good” estrogens and “bad” estrogens. It also helps to encourage production of gentler estrogen and leads to a better balance of natural estrogen in your body. [4]


It’s important to consume a balanced diet of fruit and vegetables, but keep in mind that cooking your veggies can negatively alter DIM compounds. DIM supplements are also a better source of diindolylmethane because they come in a higher dosage than what you’ll typically get in a meal containing cruciferous vegetables.

  • Weight loss. DIM increases the amount of lipolysis, which is responsible for fat burning and weight maintenance. When your hormones are balanced, your metabolism will be higher, which results in less fat stored in your body. [10]
  • Anti-inflammatory effects. It helps to activate an enzyme called activated protein kinase, or AMPK. AMPK promotes the breakdown of glucose for energy, it assists in the delivery of oxygen and acts as an antioxidant. [4,5]
  • Acne. Many adult women suffer from hormonal acne. An excess of estrogen in the body can lead to other hormones, like androgen, rising to balance it out, thus, leading to to acne. If you reduce the level of estrogen, you can reduce androgen and help lower the risk of acne outbreaks. [9]
  • Menopause symptoms. Estrogen deficiency is a common symptom of menopause. DIM supplements will not increase the level of estrogen, but they can help metabolize estrogen. Healthy level of estrogen can help with hot flashes or night sweats.[4]

DIM Supplement Warnings

DIM is not recommended for pregnant or breastfeeding women, for children, or for cancer patients. DIM can possibly worsen hormone-sensitive conditions (such as breast, uterine, or ovarian cancer). It also isn’t recommended for those with kidney disease. If you have a hormone-related condition, make sure to discuss DIM with your doctor, because it can sometimes block estrogen activity. Taking larger doses can be unsafe; possible side effects of using DIM supplements include headaches and nausea.[6,8]

More warnings to consider:

  • Before taking a DIM supplement, make sure to consult with your physician and follow instructions, being careful not to take more than the recommended dose.
  • If you take any prescription medications, make sure there are no adverse effects. Keep in mind that not all natural products are safe.

  • Hello! I started taking DIM two weeks ago, and my face has been breaking out worse than before. I am also taking milk thistle to help my liver. Is it common for acne to get worse before it gets better on DIM? How long before I should give up on DIM?

  • Agnes M.

    Hello Kainyn. I am sorry to hear that you feel like DIM supplement seems to be not helping. Like every supplement it can work differently for everybody. Always check with your doctor.

  • will dim help hot flushes in men taking hormone therapy for prostate cancer. I take 4 a day to help my cancer bit I should go on zoladex but gave me terrible hot sweats had to stop it

  • I started taking DIM a few years ago and was amazed at the difference. I had been suffering 3 weeks every cycle with terrible cramps. I was desperate enough to go on Lupron, which got rid of the cramps but started a slew of other problems. I chose the cramps over the other symptoms and stopped the Lupron. A friend recommended DIM. After a couple of weeks i did not think it was helping so I stopped taking it. A few days off of it and I realized it had been helping after all! My cramps had decreased, but slow enough that I did not realize it. When I stopped taking it, they came back to the same intensity. I went back on DIM, and am happy to say that after another week or so, my cramps completely disappeared and the only time I feel them now is when I forget to take DIM for a few days. I take 200 mg each morning. I am thinking about splitting that up 100 mg in the morning and 100 mg at night to see if it helps with the night sweats.

  • Hi Bob,
    You should always consult with your doctor before deciding to take supplements.

  • Osbaldo G.

    I’m a 45 years old male, about 2 months ago I started testosterone pallets treatment. The doctort inserted 11.5 pallets of 100mg each in my butt.
    He recommended to take DIM
    I’m taking 300mg of Dim
    200mg in the morning and 100mg. At night.
    But i noticed that 30 min. After taking Dim my nipples get hard, sensitive and they hurt.
    Why do you think that is happening??

  • I have found that DIM really helps regulate my pre menstrual symptoms. Without it I feel extremely nauseous and faint, fatigued and my menstruation is excessive. DIM has elleviated all of these symptoms to the point that menstruation is almost a surprise when it comes about, although very regular.

  • Can taking DIM 250 mg for a while cause uterine bleeding?

    I’ve been taking dim since feb 8th and my skin has cleared up tremendously. I used to take it a few years ago for my skin but stopped because it’s not recommended to take for long periods of time, some recommend taking it for six months and then stopping for six months and then taking again. My headaches went away after about 5-7 days and my skin did not get worse before getting better. It just started getting more clear and the redness went away as well. I should mention I’m plant based and many people find that dairy and high fat foods break them out, so I would suggest limiting those and supplementing with the dim. I forgot how nice my skin gets when taking this supplement , I will probably have to stick with the six month program for a bit. This is honestly the only thing that actually works for my adult acne (I’m 24), and it doesn’t really matter much what I’m using on my face. In fact I only wash with water in the morning and that’s it, no moisturizer or sunscreen—mostly because it’s winter and I also just want to use less products and have a minimal as possible skin care routine. At night I use yes to grapefruits scrub cleanser and use the yes to grapefruits serum every other night and a moisturizer on the nights I don’t use the serum. I rarely wear makeup and I try to eat as clean as possible, only eating junk foods on the weekends. Hope this helps someone!

  • I read a book which dealt a lot with oestrogen dominance and talked about DIM so decided to give to a go. The capsule I take has 250mg of DIM and a few other ingredients. I took the first capsule at night after dinner and the next morning had what I thought was a migraine. I was ill. I never associated it with the capsule to begin with so took another but this time after lunch. The next morning I was unwell again but not as bad as the previous day and then I thought maybe it’s the DIM. I had read that some people have side effects which diminish over time so I persisted as I believed I would get good results. After 6 days the side effects were gone and after 2 weeks I can already fit clothes I have not worn for years. I have not changed anything else in my life, just added DIM and I feel amazing and the weight loss has been incredible, my love handles I thought I had for life are virtually gone. I am a healthy female on no other medications I just had weight gain that crept up for no good reason and now I know it is oestrogen dominance.

  • Hello,
    I had a hysterectomy and oophorectomy 18 months ago. I am 40 yrs old. Today I had HRT pellets inserted for the first time. My Dr. recommended DIM to prevent the Testosterone converting to estrogen. Is DIM known to help with this? The last 18 months have been sheer hell as I have been trying to find balance of my hormones now that I have no ovaries.

  • Laura C.
