With all of the DIM supplements sold on Amazon, which are the best and which cause the most side effects?
If you've ever shopped on Amazon you know there are thousands of choices when it comes to supplements. In particular there are many DIM supplements on Amazon which claim to provide relief from symptoms of estrogen dominance such as bloating, fat gain, hot flashes, and gynecomastia.
We've listed here what we think are the 7 best DIM supplements on Amazon so you can make an informed decision about the best one for your body's needs.
Estrohalt is our number one pick for best dim supplement because of the quality of ingredients, price, and effectiveness. As it is a tablet it can be broken in half to judge the strength.
It is the only estrogen blocker on this list that does not contain BioPerine.
From our research BioPerine increases the bioavailability of B-vitamins which none of these dim supplements contain. For this reason it may or may not increase absorption of other ingredients.
Estrohalt was the #1 best selling dim supplement on Amazon UK, but unfortunately Amazon UK has recently banned the sale of all products containing DIM as DIM can no longer be sold.
A new European formula is now sold on the Amazon UK and EU marketplaces.
We suggest buying Estrohalt as it has better bioavailability, less adverse reactions, and a more attractive price compared to other estrogen blockers that are sold.
2. Zhou DIM Active
Zhou DIM also contains activated broccoli seed extract which is converted into DIM when absorbed in the body. It also contains vitamins C, E, and BioPerine.
It has been shown in studies that vitamin C may have a possible interaction with estrogen however Zhou Active only contains 60mg which is not enough to have an actual effect. As it is an acid it a detriment to absorption of the other ingredients.
There are very little studies showing the effect vitamin E has on decreasing estrogen. It could help with the absorption of DIM because it is vitamin that is fat soluble, but again there isn’t enough milligram to have an effect.
3. Genius Estrogen Balance
Genius DIM supplement contains only 150mg of DIM along with 5mg of BioPerine, and 150mg of Grapeseed Extract.
We think Grapeseed extract is a beneficial ingredient for reducing estrogen as it has been shown to be an aromatase inhibitor which stops androgens from converting to estrogen in the body.
Genius DIM only contains 30 capsules per bottle which is the least lasting product on the list. If you take more than 1 capsule per day you will be going through the container pretty quickly.
4. Dynamic DIM / Effective Nutra
When we reviewed this product it was still called Dynamic Nutrition DIM, but as of recent they have changed the name to Effective Nutra.
This supplement has 300mg of DIM and 5mg of BioPerine. We don’t suggest this supplement for new time users because of the high amount of DIM which could be detrimental.
5. Smoky Mountain Nutrition
Smoky Mountain has 200mg of DIM which may be strong for some people who are just starting out taking it. As it is in capsule form you can’t just take half of a serving.
It also contains 2.5mg of Bioperine which doesn't have any effect on lowering estrogen.
Side effects such as hair loss and nausea have been mentioned by customers on Amazon.
6. DIM Plus
Nature's Way DIM Plus is another supplement that is a capsule, so again you cannot break it in half to judge the strength.
There are 120 capsules per bottle and the serving size is 2 capsules for both men and women. For more pronounced results the bottle says to take double the recommended dose. We read reviews of people taking 6-8 capsules a day.
Taking this many capsules per day will make the bottle run out more quickly and also makes us question the potency of the product.
7. Nutricost DIM
If you take a look at the Amazon listing for Nutricost DIM you will see there is very little written about the effects of the supplement and what it is promoted for. As like other DIM supplements we believe their product is for reducing estrogen.
We read in some reviews that some customers needed to take 4 capsules a day to feel any effects while others became ill and experienced hair loss. As it contains 300mg of DIM side effects can be more common as it is a high dose.
CONCLUSION: Our Recommendation is Estrohalt
All of these supplements could be helpful for PMS, menopause, and balancing estrogen. Many people use them and like them as shown in Amazon reviews.
Our recommendation is Estrohalt because it has better ingredients for these symptoms and the least side effects of any of the products.
The Estrohalt bottle will last you longer if you are splitting the pills which you cannot do with any of the other dim supplements.

Does DIM Really Work?
Yes, DIM really does work if you take it correctly and at the right dose. Some DIM supplements work better than others depending on the ingredients, potency, and for the specific reason someone might take it.
There are people who feel effects from DIM within the first few days of taking it while others may need a couple of weeks for it to build up in their body.
Are DIM Supplements Safe?
Many people take DIM and experience safe results. With that being said, everyone has their own body chemistry and it is important to consult a physician to ensure you are taking the proper dose that will give you positive effects instead of side effects.
What is a DIM Supplement Used for?
DIM (diindolylmethane) is beneficial for people who are struggling with estrogen dominance. Estrogen dominance occurs when there is an excess amount of estrogen in the body and effects both women and men.
Symptoms of estrogen dominance include fatigue, mood swings, acne, bloating, and especially fat gain around the abdominal area. It is common in men for fat gain to accumulate around the breasts which is called gynecomastia or "gyno".
When Should I Take DIM? In the Morning or Night?
DIM could be taken in the morning or at night. If DIM is helping to balance your estrogen levels then you may notice an increase in energy and taking it earlier in the day may be a better option. Another sign of balanced estrogen levels is better sleep quality so DIM can help in that sense too.
