What is Estro DIM?

To begin with, Estro DIM is a dietary supplement claiming to support estrogen metabolism in men and women. The ingredients are curcumin 600mg, DIM – diindoylmethane 150mg and Bioprine 2mg. The recommended serving is two capsules per day. Portability is a benefit.

Estro DIM is made by NuMedica, although there’s no mention of when the supplement hit the shelves. You can purchase the product on the official website and through trusted retailers. We like we found some positive customer comments and that it contains a few natural ingredients, but read on…

Ineffective – “Does Estro DIM Work?”

The first concern related to the effectiveness of Estro DIM ingredients. “When a product seems to be hit or miss, it’s a sign that it may not be all that it claims to be,” said our Research Editor. “With this one, dieters aren’t too impressed.”

”Didn’t do anything for me, tried it for one month,” said a customer.

”I found this no help at all,” commented another.

There were many Estro DIM reviews stating the opposite.

“I have been dealing with estrogen dominance for many years. My doctor suggested this product to keep the DHEA and testosterone I am supplementing with from being converted to estrogen. Roughly one month after I started taking it my hormones were tested and all levels looked good.”

Side Effects – “Not Good!”

Estro DIM side effects were often discussed in forums. “First time I took it (just one pill) and the next day I was cramping up,” said a customer.

”Developed headaches from using this product. I think DimPlus is better,” stated a consumer.

However, some didn’t experience any negative side effects.

“Been using for more than two years. No side effects at all. I feel so much better,” said a user.

“I was crying for no reason and awake all night from hot flashes and night sweats. Cut my hot flashes and night seats,” said another.

Over the years, our experience has taught us that all it takes is an issue like negative side effects to reduce long-term success. If Estro DIM doesn’t work or causes side effects, this could be a problem.

The Science – “Solid?”

Studies show curcumin, found in many cruciferous vegetables, helps support healthy estrogen metabolism. Resarch also shows the DIM phytonutritent works to form healthy metabolites for the hormone, and increases potential for greater antioxidant activity. At DietSpotlight, we want to see science before we can recommend any product, and we’re glad when we do find it. However, our issue with this supplement is that it may not contain the clinically effective doses of the tested ingredients and there are no studies available on the official website.

What Users Are Saying

"”If you’re having menopause symptoms, I highly recommend you try this for relief. I was crying for no reason and awake all night from hot flashes and night sweats. This cut my hot flashes immediately and I’ve only used it 3 times.”"

"”The first time I took it, the next day I was spotting. I’m not sure if it’s related but I will see. This has never happened before.”"

The Bottom Line – Does Estro DIM Work?

What’s the real deal with Estro DIM? We like that it contains a few natural ingredients and that we found some positive customer comments. There is a concern that the available research doesn’t particularly point toward this supplement being as effective as claimed. We’re also concerned about reports of ineffectiveness and side effects.

If you want to boost results, we suggest going with a supplement backed by research and supported by positive customer comments..

Among the best products we’ve seen this year is one called Pronabolin. It is not an artificial testosterone supplement, but rather a unique blend of clinically-tested ingredients shown to naturally boost the hormone levels in the body. Our review of customer feedback shows no mentions of harmful side effects, which lets us know people are happy with their results.

In a sign of confidence in their supplement, the makers of Pronabolin are offering a multi-bottle discount and a 120-day money-back guarantee.

What is in EstroDIM?

Estrogen is a combination of the female hormones estradiol, estrone and estriol, which are important for the body to function properly. EstroDIM is a supplement that supports proper estrogen metabolism through the combined benefits of the cruciferous vegetable metabolites Indole-3-carbinol (I3C) and diindolylmethane (DIM).

Estro DIM - What You Should Know

Estro DIM is a supplement that claims to help control the metabolism of estrogens. There is mention of environmental estrogens, which are a huge deal in the nutrition world. Supposedly estrogens are found in meats and from other natural sources and those estrogens are causing irregularities in the human body. With the right amount of estrogens in the body everything just works better. But, there are a lot of questions surrounding environmental estrogens and the efficacy of estrogen-balancing supplements.

We were able to find a complete ingredient list for Estro DIM from NuMedica. The list shows just three ingredients, one of which is DIM.

List of Estro DIM Ingredients


  • Curcumin
  • DIM – diindolylmethane
  • Bioperine

Product Features

We found quite a bit of information on DIM, including many clinical trials (some on-going) in the field of cancer. This is where we expected to see a supplement like DIM because if it can help control the metabolism of estrogen it may help control estrogen levels in patients with estrogen-based cancer. The Curcumin and bioperine in Estro DIM are just included to help the DIM absorb more efficiently. There is no added benefit in terms of estrogen metabolism associated with these ingredients.

With the clinical research on DIM in the cancer field being prominent, what is the connection between weight loss or bodybuilding and DIM? Well, if the bodybuilder is taking prohormones, estrogen levels can grow out of control causing gynecomastia and other negative side effects. Estro DIM may help prevent this effect. In female bodybuilders, Estro DIM may also help keep estrogen in check.

There is no connection between Estro DIM and weight loss so the dieter will not see any benefit from taking this supplement.

Disadvantages of Estro DIM

Estro DIM is an extreme specialty supplement that has no effect on the average dieter. The supplement is designed to support healthy estrogen levels in men and women. This could be beneficial for the fitness or bodybuilding professional, but the average person does not typically need estrogen metabolism support.

According to NuMedica, the supplement should be taken as instructed by your medical professional. There is a chance this supplement could be suggested by your doctor for reasons other than those stated here.

4 Estro DIM Reviews

  • Can take with other meds.

    Just recently had an oopherectomy and now on Minivelle hormone patch. Should I still take Estrodim?

    • Maribel (Editor)

      Hi L! Because of possible interactions with having an oopherectomy, please make sure to consult with your physician before taking this product.

  •  This one works the best
    Shirley (Verified User)

    I have found Estro-DIM to be very helpful in controlling super-heavy menstrual flow. I’ve tried several other products — including some containing DIM, but this one works the best.

    • Donna Lambert

      I started taking Estodim and immediately my cycle went from every 2-weeks, to once a month, with less bleeding.

      I ran out and within the week, started a break through bleed that lasted 8 days.
      Never again will I go with out it until I go through menopause.
