Smoky Mountain Naturals Dim Review- Any Side Effects in 2018?

smoky mountain dim

Smoky Mountain Naturals 200mg DIM supplement has good reviews, but can the ingredients actually cause side effects?

Smoky Mountain Dim claims to be an all natural, safe, herbal, estrogen-free alternative supplement for balancing estrogen levels.

What is DIM?

DIM is short for 3,3'-Diindolylmethane and is formed by the breakdown of the phytochemical indole 3-carbinol. I3C is found in cruciferous vegetables such as broccoli, Brussels sprouts, kale, and cabbage.

DIM helps with those who have estrogen dominance which essentially means too much estrogen. It is actually a coined term by Dr. John R. Lee (a pioneer in the study and use of the hormone progesterone) and is described as: 

A condition where a woman can have deficient, normal or excessive estrogen, but has little or no progesterone to balance its effects in the body. Even a woman with low estrogen levels can have estrogen dominance symptoms if she doesn 't have any progesterone. (1)

Signs of estrogen dominance include abnormal periods, sluggishness, slow thyroid, trouble sleeping, fatigue, and fat gain specifically around the abdomen.

DIM is also an aromatase inhibitor which means it stops the conversion of androgens such as testosterone into estrogen (2). This makes DIM a popular supplement not just for women but for men as well.

Benefits of DIM

  • Reduces acne and helps even skin tone.
  • Reduces symptoms of menopause, PMS, and estrogen dominance
  • Weight loss
  • Reduces risk of estrogen-based cancers like breast cancer (3) 
  • Promotes hormonal balance
  • Can be obtained by eating certain foods

Who Can Take It?

Even though DIM is mostly promoted for women's health, men can also benefit from taking it to balance their testosterone levels as estrogen metabolism is what supports testosterone. (4)

Should You Combine DIM With Other Supplements?

From my experience I find that taking Biotin with a DIM supplement is beneficial because it will help stop hair loss. Hair loss may occur when your estrogen is lowered too much.

DIM can also be taken along with an indole-3-carbionol supplement for extra estrogen lowering results. There should not be a reason why you can not take a multivitamin along with this supplement.

We recommend that you please consult your doctor before taking a DIM supplement to go over any interactions that DIM or other ingredients in the supplement may have with your current conditions, medications, or supplement regimen.

Bioperine is a form of black pepper.​​​

What is the Function of BioPerine?

The function of Bioperine is to increase the absorption of minerals and B-vitamins. This DIM supplement does not contain minerals or B-vitamins so we do not see the reason for adding it in. 

Smoky Mountain Naturals Reviews on Amazon

DIM 200mg Plus Bioperine reviews on Amazon has 4.1 out of 5 stars.

Some reviewers have said that it helps to clear their acne, lose weight, and lessen symptoms of PMS and menopause. Others have experienced headaches, nausea, and hair loss as their estrogen dropped too low. These are signs that the product is working, but it can be hurtful to the body.

Hair Loss Disaster

Makes your hair shed ALL OVER. Eyelash hair, eyebrow hair, pubic hair! I only took it for a week and discontinued when my hair began falling out. It’s been OVER A MONTH since taking this product and my hair is STILL SHEDDING. I reached out to Smoky Mountains Naturals and they take ZERO RESPONSIBILITY for the LASTING effects of this supplement but told me to see a doctor because it seems like there is something wrong with my hormones. After that they stopped replying to my emails. Buyers BEWARE. Be careful of what you put into your body!

Losing weight taking this supplement after two months has been slightly easier, it's not a miracle weight loss pill or anything. I have pcos and am almost 30 years old so I was nervous to take something geared toward estrogen. A big symptom of my pcos has been periods about two weeks late usually, terrible pms and acne breakouts around that time. After taking this for two months, my period was right on time for the first time since I can remember, very mild pms this cycle, and no acne! I will continue to use this for sure.

Smoky Mountain Naturals vs. Estrohalt

estrogen blocker for women

Estrohalt is available on Amazon US, UK, and CA.

Smoky Mountain DIM are capsules and can not be broken in half unlike Estrohalt. DIM supplements may be strong for some people so if you take a capsule you do not have the option to take a lower dose to judge it's strength.

Smoky Mountain Naturals DIM contains Bioperine which is derived from black pepper and has been shown to increase the absorption of B-vitamins, but not DIM or any other protein or amino acids for that matter.

Estrohalt does not contain this ingredient because frankly it does not do anything if there are no vitamins or minerals involved and will also cause side effects such as facial redness.

The only way that Bioperine may be beneficial in this product is that it has a slight thermogenic effect. It is only added in a 2.5 mg though so it it may not be enough to actually experience that effect.

Indole-3-carbinol is an important ingredient that is contained in Estrohalt and Smoky Mountain does not have it. As mentioned earlier, indole is a phytochemical which when broken down in the body forms DIM and is used for its antioxidant and cancer-fighting properties. (5)

I3C is both an estrogen blocker and aromatase inhibitor because it converts into DIM, blocks the actions of estrogen, as well as binds to the aromatase enzyme and prevents it from turning testosterone into estrogen.

Using a product like Estrohalt that contains both an estrogen blocker and aromatase inhibitor will most likely help decrease the side effects of too much estrogen more effectively.

We believe the best DIM supplement is Estrohalt for these reasons.

Pros & Cons


-Gluten, GMO, dairy and soy free.

-Suitable for vegan diets.

-Effective for lowering estrogen and side effects of too much estrogen.


-Cannot be broken in half because they are capsules.

-Contains Bioperine.

-Claims to be "all natural", but does not back this information up in any way.

-Should not be taken for a long period of time.

  • Hair loss
  • Anxiety
  • Dehydration
  • Nausea
  • Allergic reactions such as hives, rash, and redness from Bioperine
  • Headache
  • Decreases estrogen too much

I have personally experienced hair loss when taking too much DIM. I had to lower the dose and not take it daily while also supplementing with Biotin to stop my hair from falling out.

CONCLUSION: Should You Take Smoky Mountain DIM?

Both men and women need a healthy level of estrogen and testosterone in their bodies otherwise they may experience side effects such as low energy, acne, weight gain, and mood swings. DIM can help balance these hormones and stop these negative side effects.

Products like Smoky Mountain contain black pepper in "Bioperine" which does not have any effect on estrogen but instead can cause side effects. We do not think Bioperine works in this supplement.

This product may work best with a healthy low carb diet as lowering carbs will result in less bloating and will make you feel better. Always be sure to drink enough water to improve the effects. We also recommend a product that does not contain Bioperine and that can be broken in half for best results.
