What Exactly Is Diindolymethane? (DIM)

Before we get to our list of best supplements, let’s take a moment to explore what exactly DIM is. Having a good understanding of it will inform us in our choices of best products. 

Diindolylmethane is a natural compound made in the body after digestion of indole-3-cabinol, which is found in cruciferous vegetables. It’s one of the main reasons that we consider vegetables such as broccoli, kale, etc to be so positive for our bodies.

It is linked to many different health benefits including skin, lung, liver, antioxidant properties, cognitive properties, and anti-inflammatory properties. 

Some research still is needed for exactly what DIM does for your body, but it is currently used in a medical setting to treat recurrent respiratory papillomatosis, which is a rare disease in which tumors affect the upper respiratory tract. 

Even though the full health benefits of DIM have not yet been fully explored, it is a popular supplement that many people take and express its health benefits through anecdotal evidence.

In recent years DIM supplements have increased in popularity and there are many companies dedicated to bringing high-quality products to consumers.

Top 5 DIM Supplements

  3. DIM For Men By Natural Balance
  4. Nutricost DIM capsules

The Full List

1. Diindolylmethane From

This product by bulk is simplistic and comes in powder form. Bulk supplements have made sure you can pick from a massive variety of different sizes, from 10grams all the way up to 5 kilograms.

Powdered DIM can be good if you’re not great at swallowing pills, but it also offers you a lot more control in terms of how much DIM you’re ingesting. Pills generally come with strengths of 100-300mg, with powder you have a lot more leeway. 

Powder can be great if you’re trying DIM for the first time and are unsure as to how your body will react. You can slowly add additional amounts of powder as your body becomes more used to it. 

It also has no added ingredients, such as sugar, soy, dairy, yeast, or gluten. It is also lab-verified, third-party tested and manufactured to cGMP standards which gives you a level of quality assurance.

The recommended servings size for this product is 1/10 tsp, one to two times daily. 


  • Size options – great if you’re looking to try a small amount or to bulk buy.
  • Powder – no need to swallow pills!
  • No added ingredients! 


  • Packaging – awkward plastic packaging. 

2. Mason Natural DIM Diindolylmethane Capsules

Mason Natural is a company that has been in the health business for a long time. Established in 1967 that began in small, local drugstores, Mason has since expanded their presence and are now well known worldwide. With a selection of over 300 vitamin supplements to their name, it’s a no-brainer that their Diindolylmethane products would be of the highest standard. 

These capsules by Mason Natural each contain 100mg of DIM which is a standard dose for an adult to consume. There are 60 capsules within this container, which covers you for around 60 days. They are also a source of calcium with 35mg of calcium per serving size which is 4% of your daily value. 

They contain more extra ingredients than some of the other DIM supplements on this list, including cellulose, gelatin, magnesium stearate, silica, and titanium dioxide. If you’re worried about extra ingredients, Mason does promise no added soy, dairy, fish, tree nuts, peanuts, eggs, and crustaceans – however, it is best to check the ingredients for specific allergens. 


  • Capsule form – for easy and quick consumption
  • Amount – 60 capsules so you’re covered for around 2 months. 


  • Gelatin – contains gelatin so not suitable for vegetarians as well as certain religious dietary restrictions. 

3. DIM For Men 60ct By Natural Balance

These capsules by Natural Balance are blended with DIM, Maca, and broccoli with the focus of specifically improving prostate health and a healthy reproductive system for men.

These capsules come with 200mg of Maca, which is a plant known to have a variety of health benefits. It includes 150mg DIM per serving, which is slightly higher than other amounts of DIM on this list. 

This product also contains 50mg of Broccoli in the form of Brassica oleracea italica, which is a seed extract, cellulose capsule coating, maltodextrin, rice hill concentrate, and rice bran extract. 


  • Maca – comes with maca which has a variety of health benefits.
  • DIM – 150mg of dim per capsule

Amount – 60 capsules. 


  • Additional ingredients – not for you if you’re looking for pure DIM.

4. Nutricost DIM capsules

Nutricost DIM capsules are a product made for their high quality and potency. Each capsule comes with 300mg of DIM which is rather high. We found that this product sets itself aside from others because of its inclusion of BioPerine.

BioPerine is an addition that helps your body to absorb the DIM. We were also impressed by the number of capsules per bottle, which will last you for 4 months when taking one per day. 

These capsules are vegetarian, Non-GMO, and Gluten-free which makes them suitable for a variety of different dietary requirements.

They are also 3rd party tested and made within GMP regulations and allergen-friendly, with a guarantee of none of the 8 major food allergens. 

It is worth noting that the 300mg serving of DIM is rather strong, so if you’re somebody who has never taken DIM or is not taking it under the advice of a physician, it might be best to take care when introducing that much DIM into your body. 


  • Allergen friendly 
  • Vegetarian friendly
  • Amount – 120 capsules! 


  • High dosage – 300mg dosage which is triple some other brands. 

5. DIM by Lifetropics

If you’re looking for another DIM capsule that comes with more capsules than 60, this product by Lifetropiucs might be the one for you. They are a good middle ground in terms of strength, with each capsule containing 200mg of Diindolylmethane.

This product also comes with an additional ingredient to increase absorption rates, though this time it’s black pepper extract (20mg). 

These capsules also set themselves apart from others on the market as they are completely vegan friendly. They are also lab tested with a high emphasis on the purity of their ingredients, with tests that prove the product is free from microbes, pesticides, and heavy metals.

We found that one of the best things about this product was the size of the capsules and how easy to swallow they were. 


  • Vegan-friendly – not just vegetarian!
  • Black pepper – added for absorption
  • Amount – 120 capsules each 200mg


  • The number of capsules and their strength might be a lot to commit to if you’ve never tried DIM before. 

What To Look For In A DIM Supplement

We know that sometimes the jargon, language, and stats around supplements can be difficult to wrap your head around. Sometimes it’s unclear if something is a benefit, or if a company is just trying to deceive you.

That’s why we’ve created this helpful buyers guide to run you through each aspect that we considered when making this list. We will break down important things to keep in mind when you’re searching online or in stores for your perfect DIM supplement. 

Dosage of Diindolylmethane

The first thing to consider when selecting your product is the amount of DIM you’re looking to consume. The average supplement for DIM is very subjective depending on the person, but on average 150-200mg is normal for most people.

If you take more than this, it is more likely you will encounter adverse side effects such as headaches, nausea, and vomiting.

 If you have never taken Diindolylmethane before, it’s probably best, to begin with, smaller doses. Generally, powders are great for first-time users, as you will be able to more easily temper how much DIM you are ingesting as well as change your dosage on the fly.

If you go buying some of the stronger capsules available such as 300mg, you’ll be stuck with one option – a high dosage. 

On the other hand, if you’re somebody who has tried DIM products in the past but has never seen any of the benefits, then it might be better to experiment with some higher dosages. Everybody is different and some people need a much higher daily dosage before they are happy. 

Either way – make sure you consider dosage before you choose to avoid any unwelcome side effects. Generally, we suggest 100-150 as a starting dose. 

Amount Of Capsules/Powder

Amount is an important thing to consider here. Generally, DIM capsules tend to come in either 60 or 120 options and the suggested serving is one capsule per person per day. So if you’re on your own then they will last you either 2 or 4 months. This is quite a long time, but also quite an investment as prices often match this kind of time period. 

With powder there are generally far more options you can pick, so if you’d like to try a small amount first you’ll be able to do that. Generally, capsules are more convenient to consume but also much more of a commitment than powders. 

Our advice is to only buy in high quantities if you’re sure that DIM is a beneficial supplement to you. If you’re sure that it is, 120 capsule packs would be a great purchase.


Ingredients are something that is vitally important to keep in mind when looking for your perfect supplement. Ask yourself – are you looking for something that is exactly what it says on the packet or something that will offer you additional benefits? 

DIM products have a range of different options – from products with a list of ingredients, to products that just have DIM and nothing else. It is common to find DIM within other supplements and health food products. 

Generally, if you’ve been advised to take DIM by a healthcare professional, it’s best to find as close to pure DIM as possible.

If you’re looking for a selection of different ingredients with different health benefits that work together, then you should check the label of whatever you’re buying

It’s also important that you check for allergens you might have issues with, as well as if you have any specific dietary restrictions. Many health capsule products come with gelatine as it is used as a binding agent.  

Final Thoughts

We hope our guide has given you some good ideas about the best DIM products on the market today, as well as some tips for choosing on your own.

DIM is a supplement that has been growing in popularity over recent years and its health benefits are being increasingly researched and understood. Whatever your reasons for taking DIM, make sure you do your research to find a product that is right for you.

Frequently Asked Questions

Just before we finish – here is a handy FAQ section that will give you answers to some of the most common questions surrounding DIM.

What Does Dim Do For A Woman?

DIM as a supplement helps in the conversion of estrogen to estrogen metabolites, helps to relax muscle cells, and helps your body to repair and grow better.

Estrogen metabolites are important because it affects the growth and function of different tissues throughout the female body. Estrogen plays a vital role in your bones and heart as well as influences your mood. 

Is DIM A Safe Supplement?

This is a question that has been asked many times, and for the most part, it seems that DIM when taken as a supplement or as part of your regular diet has good side effects. DIM has been evaluated many times over many years and there are no strong reports of any negative effects.

It is important, however, to be careful about how much DIM you take at any given time, as high doses can have negative side effects. That said, these side effects are likely to be mild and the same as any other supplement if you take it in excess.

When Is The Best Time To Take DIM?

We recommend taking DIM early in the morning. As with anything in capsule or powder form, it is usually best to take it with water and food. If you struggle to swallow capsules, try it at the same time as water and it will go down much easier.

Can DIM Make You Gain Weight?

DIM is directly linked to estrogen metabolism which has a lot to do with body weight. Though DIM has been linked to weight loss, more study is needed before we can say it has any clear link between weight gain and loss. 

What Are The Benefits Of Taking DIM?

Dim has many benefits but here are some of the most researched and most commonly stated:

1. Slowing cancer cells
2. Enhancing various cognitive function
3. Improvements of mood
4. Boosting antioxidants
5. Aiding estrogen metabolism. 

How To Get DIM In A Natural Diet?

DIM is what is known as a phytonutrient, also known as a plant nutrient, that is found in cruciferous vegetables. Cruciferous vegetables are rich in various nutrients including vitamins C, E, and K. The way cruciferous vegetables lead to DIM is through chewing, which releases plant enzymes.

These enzymes then travel to the stomach and make contact with stomach acid – from here they are turned into indole-3 carbinol which creates DIM.
