You Can Reduce Excess Estrogen with Supplement DIM

You Can Reduce Excess Estrogen with Supplement DIM

CB060669Many fertility issues are the result of having estrogen dominance in the body. There are many ways for the body to become estrogen dominant, including:

  • The environment
  • Eating non-organic meat
  • Stress
  • Processed soy foods
  • Chemicals in products

The good news is that there is now a natural way to rid the body of an overabundance of estrogen: a supplement called DIM.

What is DIM?

Scientist knew there were powerful nutrients in crucifers like broccoli, cauliflower, kale and rutabaga, but until they began to isolate the various phytonutrients, they didn’t realize just how important they were. One of the plant nutrients discovered was DIM, which stands for diindolylmethane. It comes from the plant chemical I3C short for indole-3-carbinol.

To get just 10-30 mg of DIM you would have to eat one-and-a-half pounds of cruciferous vegetables!

Diindolylmethane releases in the stomach after you chew and swallow the vegetables. It balances the hormones and aids in the breakdown of estrogen. Estrogen dominance is a major cause of the fertility issues women face today. Endometriosis, PCOS, and Ovarian Cysts, are all estrogen dominant conditions.

DIM also helps men. Both men and women’s bodies can experience estrogen dominance. Men’s estrogen increases with age and is subject to the same estrogen balance problems a female body may face, including improper metabolism of estrogen.

Women having troubles becoming pregnant may benefit from the hormone balancing actions of DIM.

Signs of Estrogen Dominance:

  • PMS
  • Cramps
  • Fibroids
  • Endometriosis
  • Heavy menstrual bleeding
  • Ovarian cysts
  • Recurrent miscarriage
  • PCOS
  • Lack of ovulation

What is Estrogen Dominance?

Estrogen and progesterone work in unison for the body’s benefit. As people age, their hormone levels reduce, particularly for women during the perimenopause stage and beyond. The levels of progesterone decrease faster than estrogen. This decrease may creates an imbalance in hormone levels.

Younger women can also suffer from hormone imbalance. During a normal menstrual cycle, when the egg releases at ovulation, the empty follicle changes to the corpus luteum, which is the place that produces progesterone. If something goes wrong, it may not produce enough progesterone. When you consider that progesterone is necessary for womb maintenance, you will realize the potential harm that a reduction in progesterone might have on the developing fetus or fertility.

Many factors contribute to the development of estrogen dominance. Obesity is one of the factors. The ovaries produce androstenedione, which is a male hormone. Fat cells change those hormones to estrogen. Pesticides, estrogen in animal food supplies, stress and high intake of caffeine also are factors attributed to estrogen dominance.

Studies now link infertility to estrogen dominance by disrupting the process of ovulation and in some cases lowering a man’s sperm count or causing poor sperm health. Estrogen dominance plays a key role in the development and proliferation of endometriosis, uterine fibroids and ovarian cysts, which are all issues that can dramatically affect fertility.

How to Use DIM to Reduce Excess Estrogen

DIM is found in vegetables like broccoli, Brussels sprouts and cauliflower, but in order to get just 10-30 mg of DIM you would have to eat one-and-a-half pounds of these cruciferous vegetables! While that amount is better than none, it is not the therapeutic dosage. Most experts recommend taking 100 to 200 mg of DIM a day.

  1. Where do you buy DIM?

  2. Tired of ballooning on the scale and working out like crazy with no success. PCOS is no joke, however, I came across an article on DIM and very hopeful this will balance out my hormones. I will keep everyone posted. This website is very informative. Thank you!

  3. Should you double the dosage to lose bloating from perimenopause?

    • Dear Susan,

      It is always best to follow suggested use guidelines. Exceeding this dose is not advised unless being advised to do so by a qualified practitioner. Taking more than suggested does not mean the supplement will be more effective.

  4. I have high estrogen, low progesterone, low testosterone. I just started taking DIM about 5 days ago. I also had switched my Chasteberry brand because the one I had been taking also had black cohosh in it and heard that raises estrogen. So, I switched brands about the time I started taking DIM. Now, I have broken out in hives. I’m normally not allergic to anything and have never experienced this before. Are there brands of either you recommend? Is it possible that the mixture of both caused the hives or the brand of either? I didn’t take either today because I look terrible and am itching like crazy. I’m hoping this will go away in another day or so, but would like to find new supplements.

    • Dear Leslie,

      I am so sorry this has been your experience. I have never heard of the brands of DIM that have been sold in the Natural Fertility Shop, Source Naturals and Olympia Labs, combined with Chaste tree berry, Vitex, causing hives. Might there be a filler or other ingredient that could be the culprit?

      Fertilica brand is the brand sold by the Natural Fertility Shop that we support using. There are Vitex supplements in the Fertilica brand and at the end of this month there will also be a DIM supplement. Watch for that soon!

      I too hope the symptoms subside soon!

  5. Can DIM be taken with Chaste Tree?

  6. Can DIM be taken together with Royal Jelly and Propolis? Many thanks

  7. Does DIM provide folic acid?

  8. Hi!

    I love your website! I’m learning new things every day. Maybe you can help me pinpoint if I’m estrogen dominant, I think I am, but I have so many different symptoms that I’m never 100% sure what the problem is. I have very painful ovulation, an excruciating pulling pain on one side of my body that starts a few days before in my back and upper thighs. But I also have about 3 days of spotting before my period (and about 3 days after as well) very heavy bleeding with a lot of large clots and extremely bad period cramps. My cycle is long, about 35 days, and I have quite bad PMS for a week or more, waiting for it to actually start. Would Maca and DIM help me?

    • Dear Milla,

      Thank you for your kind words. I am thankful the information we share has been helpful.

      I am sorry you are experiencing these issues!

      Our Estrogen Fertility Guide shares in great detail about estrogen and estrogen dominance. There is even a checklist to help one determine if estrogen dominance may be a issue. The guide also shared natural ways to support the body in managing excess estrogen and achieving hormone balance.

      I hope this is helpful!

  9. I have had hormonal acne all my life and at age 30 it is as severe as ever. I started taking DIM about two years ago and my acne cleared completely within one week. It stayed gone until I stopped taking DIM since my husband and I began trying to conceive and I wasn’t sure how it would affect conception. After stopping DIM, my acne came back within 4 days as bad as ever. Blood tests have revealed that my testosterone levels are elevated but my estrogen levels are on the low end of normal range. I’m curious if DIM is good for me given that I don’t have high estrogen… it certainly was a miracle for my skin!

  10. Hello, is it ok to take DIM only in the second phase (from what day and how long?) Thanks

    • Dear Maryana,

      Most experts recommend taking 100 to 200 mg of DIM each day of the menstrual cycle with meals. DIM can be taken in preparation for conception and when trying to conceive. I do not know of a reason to avoid it during the follicular phase of the menstrual cycle.

      Upon first determination of pregnancy, DIM is to be discontinued.

  11. Thank you so much for all the info.
    I have been taking DIM for a little more than a month now and I am experiencing very dry eyes and hip pains (same hip pains I usually only get during pregnancy). Could DIM be lowering my estrogen too much? I am taking it hoping it will balance my hormones and will help me stay pregnant as I keep getting pregnant and loosing the pregnancy right away (between 4 and 5 weeks). 6 pregnancies lost and after about a million tests, nothing is wrong on paper. Although I know something is not right (really bad night sweats several days before periods, late ovulation, mood swings…).

    • Hello Sofia!

      I am very sorry for your losses and what you are going through.

      DIM supports the body in metabolising excess bad estrogens, not your good estrogen. DIM is not going to strip away all of your estrogen, but remove bad estrogens from your body to promote healthy good estrogen metabolism function in the body.

      Have you begun or are you taking anything else? Might you be pregnant again?

  12. Thank you so much for a wonderful website! For few years I have been having heavy long periods, doctor said it is because I have a fibroid. I am trying to conceive for 2 years with no success. Also, for last 3 months I had no ovulation.I think I have estrogen dominance.So I bought DIM and for 4 weeks taking 4 tablets of DIM (double dose), also Donq Quai (not during period), primrose oil, black cohosh, enzymes and vitamins. My last period started 3 days late and still on for 10 days, just spotting now.Got some pimples on my face and chest, what I usually don’t get. Ordered also progesterone cream from your website, waiting to arrive. Is starting DIM can affect the time and length of period?

    • Dear Lolita,

      DIM is supportive of helping the body metabolize excess “bad” estrogen. There could be potential for the cycle to shift as a result of the body ridding itself of excess estrogen and utilizing its natural estrogens or the herbs you are also taking. These shifts should work themselves out within 1-3 cycles of use.

  13. My estrogen is high and progesterone low, both just within range so Dr wont do anything yet about not conceiving. I’m not sure which is the initial issue: estrogen dominance or progesterone deficient. Would it make sense to take DIM as well as Vitex or just one?

    • Elizabeth Willett, MA, CH

      Dear Jenn,

      Diet, lifestyle, exercise and even stress all have been found to impact hormone balance. DIM is supportive of helping the body metabolize excess “bad” estrogen and Fertilica Vitex may in part be supportive of the body’s natural progesterone levels. They can be taken together.

      Consider also learning more about dietary and lifestyle ways to support hormone balance that I mentioned in the article, Restore Hormonal Balance for Improved Fertility.

      Best wishes!

  14. I have used DIM to help with fertility and I have been pregnant twice this year. Last time I stopped the DIM on the Doctor’s advice and then miscarried a week later. I don’t know if it was related but I’m pregnant again and would like to know whether DIM is safe during pregnancy as I don’t want to stop it. If not which safe hormones should I be prescribed to do the same job?

    • Elizabeth Willett, MA, CH

      Dear Jo!

      First Congratulations on your pregnancy! What wonderful news!

      I am also sorry you are concerned. We suggest stopping the use of DIM when pregnancy is confirmed as well. Through our research we have found no reason to avoid using DIM while trying to conceive. We feel it is fine to continue DIM while trying for a baby, but suggest it be discontinued once pregnancy is confirmed.

      We have not heard of pregnancy loss as a result of discontinuing the use of DIM in early pregnancy. The reason it is not deemed safe for use in pregnancy by most manufactures is because there is no research to show if it is safe or not. Therefore for liability reasons no one can say it is safe to take in pregnancy. So, it is always best to follow the guidance of your healthcare provider. You should share your concerns with him/her and ask about weaning off of DIM rather than just stopping because stopping its use is concerning you.

      Best wishes!
