We put together a list of DIM supplement reviews to help you find the best one for your needs. We based on our reviews on the reputation of the brand, and what reviewers say. We also provide information and answers to common questions you may, such as what DIM is used for.

What is DIM?

DIM stands for diindolylmethane, and it’s something found in cruciferous vegetables. That compound is one reason why women at high risk for breast cancer are sometimes advised to eat vegetables like broccoli and cabbage.

DIM is a hormone-balancing compound, which is why they’ve have become increasingly popular. This type of supplement may help with:

  • Hormonal acne
  • Balanced hormones
  • Reducing negative effects of estrogen
  • Mood swings
  • Reproductive health
  • Fibroids
  • PMS
  • Menopause symptoms
  • Male breast growth

It’s believed that DIM can balance hormones by adjusting the amount of bad-to-good estrogen levels. It also blocks something called aromatase, which converts testosterone levels to estrogen.

According to Memorial Sloan Kettering Cancer Center, diindolylmethane has anticancer effects, although clinical data is somewhat limited. MSKCC goes on to say that in lab and animal studies, the DIM compound has not only anticancer effects but also anti-inflammatory effects.

It may increase bone mass as well, so it’s being studied for its potential benefits for patients with osteoporosis. DIM may help patients who have certain types of prostate cancer, and it may also reverse abnormal changes in the cells located on the surface of the cervix.

MSKCC specifically says the following, based on currently available research about the benefits:

  • DIM has demonstrated antiproliferative effects on cancer cell models and in animal cancer cells
  • DIM has been shown to prevent the invasion by cancer cells of normal tissue
  • There is research showing DIM’s effectiveness to induce apoptosis in pancreatic cancer cells
  • In colon cancer cells as well as prostate cancer cells, DIM inhibits CDK activity and induces apoptosis

So what exactly is DIM, aside from being a compound in cruciferous vegetables that can block bad estrogen and promote balanced natural hormones?

This popular supplement is a plant nutrient. When you chew cruciferous vegetables, enzymes are released. When your stomach acid hits these enzymes, something called indole-3 carbinol or I3C is formed. That then turns into DIM.

DIM and Estrogen

There are several types of estrogen, and one, in particular, may prevent the growth of malignant tumors. This type of estrogen is called 2-methoxyestrogens. Researchers theorize that it could be beneficial to increase the production of this good estrogen, and that’s why DIM may be a useful supplement. When you supplement with DIM, it can promote the metabolism of the beneficial estrogen, balancing hormones.

While we often think of estrogen as being something only linked to women’s health, using a DIM supplement could be beneficial for men as well.

There is evidence, for example, that DIM supplements may have benefits in preventing colorectal cancer, and DIM can also be used to prevent an enlarged prostate, known as benign prostatic hypertrophy.

Some people use DIM to help them lose weight, and as a treatment for premenstrual syndrome (PMS).

If you suffer from hormone-related migraine headaches, you might find that DIM helps with this as well. Many women suffer from migraines during a time of what’s called estrogen dominance. Other symptoms of estrogen dominance can include irritability, water retention, heavy or irregular periods, brain fog, and breast tenderness.

If you’re estrogen dominant, then it means you’re likely simultaneously dealing with a progesterone deficiency. Your brain is very sensitive to progesterone, and if you’re deficient in it, symptoms may include migraines as well as insomnia and anxiety.

Progesterone has a calming effect on the brain.

The use of a DIM supplement can help modulate your estrogen levels, which may reduce or alleviate your migraines.

Is It Safe?

DIM is considered, for the most part, a safe supplement with minimal adverse effects. With that being said you should always speak to a health care professional before you take any supplement. You shouldn’t take very large doses, because that can lead to side effects. If you do experience side effects they’re likely to be mild and may include nausea, vomiting, gas, diarrhea and headache.

If you experience stomach upset when you take a DIM supplement, you should consider taking it with food. That will likely remedy the problem.

Why Might a DIM Supplement Be the Best Option?

If you’re wondering whether or not it would be better to get DIM from cruciferous vegetables, there is a reason that a supplement may actually be better. DIM is very insoluble and not well-absorbed unless it has a “vehicle” to make it more bioavailable. DIM supplements will typically be formulated with a delivery system.

These are one of the most exciting supplements currently available in many ways, but it’s not necessarily as mainstream as some other supplements.

Top Reviews

The following are our selections for the best DIM supplements, based largely on DIM supplement reviews.

Best DIM Supplement #1:

MDacne DIM Skin Clearing Supplement

  • Unique formulation for people with hormonal acne
  • Dermatologist formulated and approved
  • Non-GMO 
  • Vegan and cruelty-free
  • Restores hormonal balance

We updated our rankings of the top supplements to include MDacne’s relatively new DIM formulation.

There are a few key reasons we like it. First, the formulation is geared specifically toward helping clear up hormonal acne, starting from the inside out. The supplement gets to the root cause of hormonal acne in adults, so if that’s your primary reason for considering DIM, this is a great option for you. This supplement can help balance levels of estrogen and androgen for clearer skin. 

We also like that MDacne provides a breakdown of each individual ingredient in the formulation.

For example, the MDacne DIM supplement has spinach powder, which can help normalize your production of keratin and reduce excess sebum. 

Alfalfa powder is high in antioxidants and contains, copper, folate, and vitamins C and K. 

The kale powder included in this supplement is rich in amino acids as well as vitamins C and E, both of which are important for skin health. Consuming kale can also be a good way to improve any clogged pores you might deal with, and to reduce oilness. 

Brussel sprout powder is included because the immune system-supporting phytonutrients. 

Finally, a big reason we rank MDacne’s DIM as our pick for the best is because they include black pepper extract, also known as bioperine. Absorption and bioavailability are so important in any supplement. If you can’t absorb what you’re taking, it’s not going to be as beneficial, but black pepper extract promotes better absorption of supplements and nutrients.
