best dim supplements

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 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 top DIM supplements on Amazon so you can make an informed decision about the best one for your body's needs.

1. ESTROHALT

estrohalt dim

Estrohalt is our number one pick that has the best diindolylmethane supplement reviews because of the quality of natural ingredients, price, and effectiveness. It is also made by what we think is the best supplement brand.

As it is a tablet it can be broken in half to judge the strength.

It is the only oestrogen 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.

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.

It is a high selling product for men and women on the market and may also have benefits for:

  • hormonal acne
  • weight loss
  • PCOS, menopause, peri menopause
  • HPV
  • breast cancer and oestrogen related cancers
  • erectile dysfunction
  • fatigue
  • obesity
  • can be use in conjunction with a keto or organic diet

It is not sold in stores like CVS, but it is sold worldwide including on Amazon US, Amazon Canada and is one of the best dim products in Australia

Estrohalt was the #1 best selling Amazon dim supplement UK, but unfortunately Amazon UK has recently banned the sale of all products containing DIM. Estrohalt is not banned, but all DIM products are. If you live in the UK or Germany you can still buy the original version of from estrohalt.com.

Estro-halt EU is a new European formula that is now sold on the Amazon UK and EU marketplaces.

For these reasons you should consider Estrohalt number 1 out of your top 5 or top 10 estrogen reducing supplements.

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 hormones. 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.

Negative side effects of Zhou Dim Active may include pain in joints, ache, or cracking.

3. Genius Estrogen Balance

Genius contains only 150mg 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.

Genius Balance adverse side effects may include headaches and a change in urine color.

4. Dynamic DIM / Effective Nutra

When we critiqued this product it was still called Dynamic Nutrition, but as of recent they have changed the name to Effective Nutra.

This supplement has 300mg and 5mg of BioPerine. We don’t suggest this supplement for new time users because of the high amount of diindolylmethane which could be detrimental.

Effective Nutra side effects may include lowering of estrogen too much.

5. Smoky Mountain Nutrition

Smoky Mountain has 200mg 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. 

SM nutrition 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

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 testimonials 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

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 the other 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 side effects can be more common as it is a high dose.

FINAL TAKEAWAY: Our Recommendation is Estrohalt

The best dim supplement for male and female reviews can be found on Acne Supplements Critic. All of these supplements could be helpful for males and females for PMS, menopause, bodybuilding and balancing estrogen. Many people use them and like them as shown in Amazon ratings.

Our recommendation is Estrohalt because it has better ingredients for these symptoms and the least side effects of any of the other brands' 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.

Many people take it 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 bad effects.

They should not be taken during pregnancy because it could interfere with the natural hormones the body produces and needs throughout this time.

If you are someone who already has low estrogen then you may need to reconsider as it could cause side effects such as joint pain, joint ache, migraines, nausea, and hair loss.
