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.

Symptoms of estrogen dominance:

Allergy symptoms like asthma and hives
Thyroid issues
Breast cancer
Breast tenderness
Decreased sex drive
Depression with agitation and/or anxiety
Dry eyes
Early onset of menstruation
Fat gain, usually around the middles
Foggy thinking
Hair loss
Increased blood clotting
Fertility issues
Irregular periods
Polycystic ovaries
Sluggish metabolism

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. I’ve been trying to get pregnant for many months and bloodwork shows I have adrenal fatigue (super low cortisol levels) so my naturopathic put me on DHEA. Would there be any issue taking DIM with the DHEA?

    • Dear Brandi,

      You will want to ask your naturopath about combining the two. There may not be concern, yet he/she should approve given DHEA is actually a hormone.

  2. Hi, I’m 34, have PCOS from the beginning of my periods, never have been pregnant. I was on a a Birth control for ~8 years, from my 23 to 31, then I quit that to watch my natural periods and to prepare to the pregnancy. During the transition period I helped my body with natural remedies and therapy (like Ayurvedic treatments, herbal medicines etc.), and my cycles became more less regular with 31-34d, but with PCOS symptoms – the one growing ovarian cyst and many smaller ones. During the past 2 years the cyst has grown from 41×37 to 67×34, and my gyn insists on surgery or taking OCP. I don’t want to do anything of that and looking for some natural solution. Could you recommend DIM in my case?

  3. I’m 53 years old and have had irregular heavy periods. I have fibroid tumors and recently had a hystroscopy for the removal of a polyp and also had a D&C done at the same time. Pathology report came back as Complex Endrometrial Hyperplasia without Atypia. Current physician suggest the use of a Mirena IUD as she said I am an estrogen carrier and the IUD will disperse progesterone as needed. I really don’t want an IUD at my age. Do you think it would be better for me to try DIM?

    • Dear Gail,

      It is common to have cycle shifts at age 53 and for many the accompanying issues you share. If you are not feeling comfortable about an IUD, talk to your doctor about DIM and using a natural progesterone cream, or work to find a practitioner who supports a more natural approach, someone near you.

      I hope you find a solution that feels right and provides you relief and balance!

  4. Hello,

    I began supplementing DIM a month ago to help my cystic acne. I have PCOS with regular anovulatory cycles (30-31 days), severe acne and hirsutism. Within the 30 days of DIM, I’ve noticed an amazing reduction in my acne; which I’m beyond thrilled about as nothing else has worked for me. However, I had some mid-cycle cramping and minor spotting, pain and swelling in my breasts and an 8lb. weight gain. I’m 5ft 6in and normally between 120-125lbs. I’m also not sleeping well at night; waking up at 3am every night. I’m not on BC or any other supplements. Are these normal reactions to the DIM or should I discontinue use? Thank you.

    • Dear Melinda,

      What I speculate is that rather than this being a reaction to DIM, it is more likely hormonal shifts and the body working to balance hormones because excess estrogen is being metabolized. Mid-cycle cramping and spotting could have been ovulation. I know many women who sleep poorly and transition through the luteal phase with some pain and breast swelling (PMS).

      What else are you doing to support hormonal balance? Have you learned about How to Reduce the Damaging Effects of PCOS on Fertility Through Diet and Herbs? I would suggest the other tips in that guide too and following a holistic program.

      It may be worth also cutting back a bit on DIM to see how that changes things as you incorporate more natural therapies. If what you are experiencing to not shift as your cycle ends and a new one begins or subside as you begin other natural therapies, it would be my best advice to reach out to a practitioner near you who can support you; an herbalist, naturopath, etc.

      I hope these are simply signs that work to balance is being done!

  5. I am researching DIM for my 19 yr old daughter. She is on Birth control because when she started her period at 15 she bled non stop heavy for three months straight. she was put on a progesterone pill for 10 days and when stopped it started bleeding again, did another 10 days bleeding stopped and once start bleeding. The gyn put her on regular birth control and for three month she was normal, but bad cramps and heavy bleeding during period. The gyn then said to just take the bc pills none stop and skip periods. that really has screwed her up. She has been tested for hormone levels and she is low on progesterone. I am wondering if DIM would help her. she has bad acne flares, hair loss

    • Dear Lisa,

      I’m sorry to hear this! My wish is that every girl’s transition to being a woman was easy, not challenging!

      With that, it may be best actually to work with a naturopath near you if you wish for a more natural approach to hormonal balance for her.

      Some tips though to try to reduce period pain/PMS: avoid consuming processed foods, dairy and refined sugar the week before a period (soda, candy, baked goods, white rice, pasta). Learn about the benefits of a whole food multivitamin and quality omega supplement like Evening Primrose Oil and Cod Liver Oil. Have her include cruciferous veggies in her diet and lots of fiber (whole vegetables and fruits). Iron may be key for her too if she is feeling sluggish, tired, low energy. She could consider smoothies with superfoods like a greens powder, avocado, Royal Jelly. It’s also important to exercise daily and try to move in order to maintain a healthy Body Mass Index (BMI).

      When all those areas are addressed and being worked on, DIM has the potential to help the body properly process/metabolize excess estrogen. It may be worth learning about the herb Vitex as well (although we can’t suggest either with birth control unless her healthcare provider okays it).

      I would agree that birth control non-stop at age 19 is not the answer, but I can also image how troublesome such bleeding is for her. I hope you find a practitioner who will help you get to the bottom of this and create a program for her that boosts her health rather than tricks the body into action.

  6. Hi,
    I recently came off my birth control pill and I’ve experience a rapid weight gain with the most stubborn fat ever! lol not as easy to lose as it used to be while on the pill. I’ve also experience breakouts all over my face, chest and back. I’m trying to get pregnant, not as easier as i thought as well lol. Anyhow, would you recommend DIM for someone in my situation?

  7. I have PCOS and experience many of the above symptoms. Is it safe to take DIM while on birth control?

  8. Thank you for this article. I just discovered this website and am learning so much. I have been TTC for over a year now. I am fit, have a healthy BMI, exercise, eat a very low processed, nutrient dense diet, meditate, etc. Despite this, I struggle with acne, horrible PMS, endometriosis, and cramps. No doctor has ever suggested estrogen dominance, but it sounds just like me. I am excited to try DIM + vitex and see what happens. Thank you for all the resources and content. I’d much rather try a more natural route first.
