This product is considered pharmaceutical grade and contains no fillers of any kind.


The supplement is considered safe as long as suggested serving size is adhered to (this includes amounts that are taken from natural sources as well, which must be counted in the overall daily dosage calculation for safety reasons). Those with a history of any kind of liver disease, kidney disease, cancer, or food allergies should first speak with a doctor.

Women who are pregnant or lactating should avoid use of this product unless otherwise prescribed by a doctor, as it may affect estrogen production during nursing. Even though humans exhibit no side effects when exposed to normal levels of DIM, it has been shown to be toxic to canines at high levels, so it should be kept away from dogs.


As a lipophilic compound, Diindolylmethane is best absorbed by the body when in the presence of oils or other compounds like it. Vitamin E is a specifically good choice to be taken with this supplement, as it will greatly improve the rate of absorption.

Customer Reviews

weakens estrodial
One of the active ingredients of cruciferous vegetables, DIM is a common-sense natural adjunct treatment widely studied for hormone sensitive cancers (eg. prostate or breast cancer), even hormone refractory cancers, by introducing cancer cell death and slowing proliferation, in vitro. According to WholeHealthMD it is also used to treat fibromyalgia, laryngeal papillomatosis, cervical dysplasia, premenstrual syndrome (PMS) and systemic lupus erythematosus, as well as to balance hormone levels, detoxify the intestines and liver, and to support the immune system. Give it three months to work, bring some vitamin E on board, and add digestive enzymes or a teaspoon of apple cider vinegar is you don't produce enough stomach acid.

Diindolylmethane (DIM) - 10g Pure Powder
As far as the effectiveness of the product goes, I cannot comment. I took it every day for a few weeks (until the package ran out) and noticed no difference in anything. BulkSupplements did a bang-up job as always on the packaging, shipping, etc. Perhaps because I received the smallest size (10g) it came in a small plastic bag inside the normal packing bag. This was a bonus since it was easier to extract and there was no mess when I opened the normal packing bag.*

A powerful punch in such a small serving
When I ordered this, I didn't notice how small the serving sizes were. When I took my first serving I took 1/2 tsp. to be on the safe side and then looked at the label. Woops! Ended up that it was a large dose of this powerful product. I now put a smidgen in my smoothies in the morning. Goodbye bad estrogen, hello good.*

(DIM) has been great!!
Great product! I was having issues with mood swings and bloating. My doctor told me it was most likely due to an excess of estrogen. I found DIM and have been using it for a month now. Its been great.*

As an older adult male with estrogen dominance, and spouse that's postmenopausal, I was interested in DIM for its ability to block the formation of "bad estrogens". I know, at my age testosterone is being converted to estrogen, and my wife needs to keep all the estrogen she still has left. This DIM is a very pure source, and is working well in our efforts to maintain healthy hormone levels.*

Diindolylmethane (DIM)
I got a sample package of this product and decided to purchase more of it to incorporate it into my regimen.

I take this product to decrease levels of "bad" estrogen. Combining this product with DAA, DHEA will increase testosterone in anyone over 30 years of age. That combination will take back the clock at least ten years. This product belongs in anyone's mix who is trying to stop aging.*

Good product & great company
I've been using this product for a while in capsule form with very good results & now getting the benefit of PURE powder from this great company...thanks BS!!!*

High Grade DIM, Very Fast Shipping!
I ordered BulkS DIM as a health supplement after reading so many great benefits it has in regards to hormones. I'm a 30 year old male who trains HIIT 5 days out of the week and wanted something to regulate my estrogen levels as opposed to committing to any "testosterone booster" supplements that I feel I am not in need for at this time in my life.

Long story short, I began dosing 100mg a day and within hours after my 3rd dose, I realized my overall mood and libido has noticeably enhanced.

DIM simply turns "bad" estrogen into "good" estrogen so don't expect a crazy shift in testosterone levels. Although, DIM does have extensive studies that show a slight increase in a males Free T, which is a huge plus for anyone looking to safely and naturally promote a healthier balance for their hormones.

Awesome quality w/ BulkS as always.... can tell by the aroma of the powder. Happy health everybody ; )*

On fence
I was hoping it would work as I have been told by my Naturopath that I have "estrogen dominance" and the DIM would help get the excess estrogen out of my body.

The first time I took it I had a histamine/allergic reaction - runny nose, mucous, cough within 15 mins... I had taken 1/8 tsp on an empty stomach. I had diarrhea for 1/2 day next day.
The second and third times I woke up with a headache.... 1/16 tsp taken with food.

I will take it with coconut oil and see if it makes a difference but if that continues to affect me adversely then I will make a homeopathic remedy from it.

The powder was sort of a coral color. IDK if that was supposed to be that color. *

Excellent addition to men and women's daily supplements.
DIM is a breakdown product of indole 3 carbinol, found in cruciferous vegetables, providing similar benefits at a much lower price. That's before even taking into account Bulk Supplements deep discount compared to all the commercial companies that sell bottles of small capsules (you don't need much DIM) for a big price.
I've taken DIM for a number of years to help block estrogen and help prevent hormone related cancers. I am also hoping to prevent prostate issues, besides prostate cancer. I'm aware also of it's use for 'female issues'. Thanks for providing this useful supplement at a great price.*

Incredible Product
I've been taking DIM for the last couple years and I must say it's helped tremendously clearing up my acne, improving my mood, and simply making life much more bearable. I'll be buying DIM from Bulk Supplements from now on.*

On 10/5/2016 James said...

Nice Product
This supplement can be expensive if ordered from other companies in capsules and packaged. Bulk Supplement's prices are quite reasonable and we have had good luck with their other products. This looks like a very affordable way to include DIM in one's diet, and we are looking forward to giving it a try.*

Hot Flash Killer
A friend of mine told me about DIM as a way to control those nightly tropical vacations.
I've taken this product in three forms from three different sources; gel cap, tablet and the pure powder form here. The powder DOES NOT mix with water, but will mix with honey making it easier to take.
Being honest here I was given a sample to try inn exchange for this review and I have to say I'm ordering more today!*

Hot Flash Killer
I'd been having "mini" tropical vacations at night, not a fun way to sleep, and my friend told me about DIM. The first night I noticed I wasn't "flashing" and was able to turn my fan down.
I've taken DIM from two prior sources one in gel cap and one in tablet form, then I tried the pure powdered form and since I don't have a way to make my own gel caps I had to find a way to take the powder.
DIM is not water soluble and tastes horrible if taken dry. I've found that mixing it with honey works best.
I will order this again and in fact will do so after I post this.
I'll be honest here and tell you that I was given a free sample of this product in exchange for this review.*

On 9/8/2016 laura said...

I got this for my girl and she just started using the product and she tells me she has noticed an ease in the severity of her hot flashes. It was the purest form I could find to purchase. The only thing I wish is we were given some direction on how to take it. It does not blend well with water, so I sprinkle on my salad. I will update my review after I use for more time.*

On 8/28/2016 don said...

Worked quickly!!
This product is so pure and clean. I am currently going through menopause and dim helps with estrogen dominance to balance out my hormones. Prices can't be beat and delivery was quick. Glad I found this website!*

On 7/27/2016 MICHELINE said...

The powder which i received smelled very nice in comparison to the last bulk order of DIM i bought from another site. I was happy with the results which i obtained by taking this product. I would recommend others to buy it as well. *

DIM Powder
Fast shipping and quality product, although it's difficult to assess direct effects when considering other variables (nutrition, workouts, etc.).*

On 6/27/2016 Slick said...

Fast shipping, quality product however does not dissolve well in water. *

On 6/7/2016 Nathan said...

Fine product, doesn't mix well
The product itself seems fine, although I haven't been taking it long enough to know if it's working. The taste isn't bad, but it really does not mix well in water.*

On 6/2/2016 Elizabeth said...

Great price
It's much cheaper than pills that I find in other places online. It helps me with estrogen dominance problems, which causes zits.
I take it with same amount of ground black pepper for more bio-availability. When I eat junk food, I take 50% more DIM than normal.*

Diindolylmethane (DIM) Pure Powder
Best to go straight to the source when looking for DIM. Bulksupplements provides a quality product, lowest price and fast shipping. I am very happy with my purchase and the results from DIM.*

DIM inhibits prostate cancer cell growth
The following is a list of clinical trials, most double-blinded and placebo-controlled, recorded at the National Medical Library, MEDLINE, as abstracted by GreenMedInfo for DIM (3,3'-diindolylmethane):

1. DIM improves the estrogen profile in postmenopausal women with a history of early-stage breast cancer.
2. DIM inhibits lung metastasis of mammary cancer cells in mice.
3. DIM (3,3'-diindolylmethane) sensitizes breast tumors to chemotherapy.
4. DIM inhibits prostate cancer cell growth.
5. The chemotherapeutic activity of erlotinib is potentiated by 3,3' diindolylmethane (DIM) against pancreatic cancer, in vitro and in vivo.*

Top Notch Company & Supplement!
Absolutely PURE supplement with amazing effects. Super fast shipping and extremely helpful staff. Great experience all the around with! *

On 5/7/2016 Craig said...

I have never come across a supplement as bad as this, not in performance wise, but as a supplement in every other way.
This stinks like old feet, tastes like old feet and won't mix with anything no matter how much you mix it. To top it, it has to be refrigerated unlike most supplements. It's like it wants to be the most difficult of all powders and if I didn't see the results I've been seeing, I'd tell this bitch to take a hike.*

This stuff is great for guys trying to keep the estrogen levels down. The shipping and quality is always great from bulk supplements.*

Estrogen control

Diindolylmethane (DIM) Powder for treatment of HPV
My cousin is a doctor and recommended I take Diindolylmethane (DIM) for treatment of my HPV (human papilloma virus). I had abnormal paps and a positive HPV test. I immediately started taking the Diindolylmethane (DIM) Powder and when I had my pap 6 months later, the HPV was negative and the pap was normal. Because I need to stay on this supplement for the rest of my life, I wanted to find a more pure (since all the capsules have many additives) product, as well as one that is more cost effective. I purchase this product 1 month ago and I am very satisfied with the product, packaging, etc. If it truly is as pure as they say it is, then I am beyond grateful to them. It costs so much less than it you were to buy the tablets in the store and it has no fillers.*

DIM Powder
I have purchased this product and I find ii very useful. I use it twice a day and my energy and stamina is up. I would tell all you hard core men and weight lifters this is the product for you. Not only is it healthy but it makes you feel great. The guys at my Gym can see the difference in me with my attitude and strength. Try you can't go wrong. *

On 12/11/2015 Timothy said...

Best ever.
I use DIM to counteract all the harm estrogen's can to to male body and bring myself to a more natural state. DIM helps clear my skin and enables me to have more stable mind state. I'll be taking DIM for the rest of my life.*

DIM for estrogen balance
I purchased this supplement to help offset my genetically inherited estrogen dominance. I'm also hoping it will also help boost my 16 year old son's testosterone levels. He has low testosterone likely caused by inherited estrogen dominance. With the constant exposure to estrogen mimicking products in our environment, we need something to assist our bodies in riding itself of the excess estrogen. Nutrahacker suggested DIM so I'm giving it a try from Bulk Supplements because their products are pure without fillers.

The only negative about this product is that it smells to high heaven! I'm solving for the taste / smell issue by putting it in capsules so that I can control the amount. *

Good for Testosterone Boosting stack
I bought this bulk DIM to add to my own home-made testosterone "boosting" stack. Goes well when coupled with things like DAA and LongJack in order to help metabolize any extra estrogen production/prevent testosterone from being converted to estrogen. Plus it's derived from veggies, so probably some other good health benefits there. Only issue I have with bulk DIM is just how bioavailable it actually is, as most commercial DIM products use proprietary delivery technology to help overcome low bioavailability. I try to blend it with some lecithin/coconut oil and other supplements in a smoothie 1-2x a day in order to help hopefully emulsify the dim for better absorption. Not a knock on BulkSupplements though, they're service and selection/pricing is quite good!*

DIM today hormonal balance tomorrow
DIM today hormonal balance tomorrow
DIM is a product very much necessary to take as a supplement for most American adults. Our society produces copious amounts of hormone altering products from plastics to birth control which end up in our systems just by their very nature. DIM produces a balance, a natural balance. It is difficult to eat enough food to receive the amount of DIM necessary to affect change. Thus, a supplement. provides for a clear alternative to prepackaged supplements. You can buy DIM from amazon from a number of reputable supplement companies in nice gel capsules, or you can save 50% to 85% and buy the bulk form and encapsulate it yourself or mix it with juice. For me the choice is evident.
The product I received was timely, well labeled, well packaged, and easy to work with. I recommend it.

On 9/26/2015 Brian said...

Love this DIM
After doing DNA testing and getting supplement recommendations from Nutrahacker, I am convinced this DIM is the best I've tried. I also hope that since my breast cancer diagnosis 11 years ago, It will help keep it at bay. Love finding natural solutions to help health issues instead of using the pharmaceutical companies' answers to illnesses. Best customer service and staff I have dealt with in a long time.*

Hormone Balance
I've been using DIM for more than a month now, and the results are amazing. I'm a breast cancer survivor, and DIM helps block bad estrogen from feeding any new cancer cells. The bonus is that I've lost weight, my hair and skin are softer, and my nails are growing long. I won't ever stop taking DIM. *

On 7/7/2015 Ann said...

Works as advertised
I buy DIM to combat the all the estrogen-like substances in our modern environment, namely the plastics we use daily. There are so many man-made chemicals in our homes that act like estrogen in our bodies. I find DIM to be a great way to overcome the odds and actually have normal estrogen levels. As a man, I must ensure I not only have a good estrogen level, but the correct estrogen. DIM's ability to turn bad estrogen into good means I'll be making this apart of my everyday supplements.*

On 6/29/2015 James said...

I am taking DIM as an estrogen blocker .According to my research, excess estrogen can cause many problems in men ,especially those who are taking herbs or pharmaceuticals to increase testosterone levels . You should take a black pepper extract for better absorption. DIM does not have a pleasant smell . I mix it in a spoonful of peanut butter, and no more bad smell or taste. I am very pleased with everything I have ordered from Bulk Supplements.

New Supplement in my regime
I am an athlete and train hard. I take around 32 supplements and have added DIM to my regime. It not only adds to the cancer fighting power of crucible vegetables like broccoli and cauliflower, but helps balance hormones so testosterone is not aromatized into estrogen which you don't want training in the gym. Especially important as you get older as men tend increase estrogen production as they age. Take this to keep testosterone at its peak.*
