Buying Guide for DIM Supplements

DIM stands for diindolylmethane, a phytochemical produced by human bodies from indole-3-carbinol, which can be found in cruciferous vegetables such as bok choy, cabbage, broccoli, collards, arugula, watercress, radishes, and Brussel sprouts. It works by optimizing your body’s estrogen metabolism, raising the concentrations of the beneficial estrogens while decreasing the concentrations of the dangerous estrogens. Although the aforementioned natural sources include DIM, we are unlikely to receive what we require from them. Let’s face it, as healthy as vegetables are, with all their health benefits and everything, they aren’t the most delicious. That is why DIM pills and other nutritional supplements are becoming increasingly popular. They’re a simple and convenient method to meet your body’s DIM needs without having to shove vegetables down your throat.

What are the advantages of DIM supplements?

Before we go into the benefits, let’s have a look at how DIM works. DIM promotes the formation of 2-hydroxyestrogen, a milder and more favorable type of estrogen. It also inhibits the function of 16 alpha-hydroxyestrone, a more stronger type of estrogen associated to weight gain and an increased risk of some cancers such as uterine and breast cancers. DIM also inhibits the enzyme aromatase, which transforms testosterone to estrogen.

The advantages are as follows:

DIM has been found in studies to help inhibit breast cancer cells from growing and spreading. They may also help to prevent malignancies of the cervix, colon, ovarian, and prostate.

  • In men, DIM has been proven to protect against prostatic hypertrophy and PIN (a premalignant disease).
  • It has been demonstrated to help people lose weight and minimize fat formation.
  • DIM supplements can aid in the treatment of hormonal acne.
  • They can help postmenopausal ladies with hot flashes.
  • They can help ladies with PMS symptoms.

They can aid in the correction of estrogen imbalance in males, lowering the risk of increased breast growth, erectile dysfunction, and infertility that can result from estrogen imbalance.

What are the potential negative consequences of taking DIM supplements?

DIM is safe to use and has not been connected to any significant adverse effects, according to existing evidence from human research on the effects of DIM supplements. However, there have been some minor adverse effects reported. Changes in urine color, increased bowel movement, headaches, and gas are the most prevalent side effects. Nausea and vomiting, diarrhea, and skin rashes are some of the less typical adverse effects.

However, even though DIM supplements are generally safe, you should not begin taking them or any other supplement without first consulting your doctor. People who are taking other medications, pregnant women, and nursing moms should be very cautious.

How do I choose which dim supplements to purchase?

Since the potential benefits of DIM supplements were known, the number of choices available to individuals like you has increased dramatically. Customers now have a plethora of options when purchasing for these supplements as a result of this. While having the ability to choose is beneficial, it also poses a dilemma. How do we choose the greatest brands for us? This section provides an answer.

Ingredients

When it comes to DIM pills, or any other supplement, the ingredients are the most crucial factor to consider. This is particularly helpful for vegetarians and allergy sufferers. Gluten-free, soy-free, dairy-free, vegan, non-GMO, and artificial flavor-free are the top brands on the market today. People with allergies should check the manufacturer’s ingredient list before purchasing.

Expert and customer feedback

Customer and expert evaluations are one of the most objective ways to assess a product’s efficacy and most common problems/side effects. Expert reviews, like this one, usually entail extensive research into the issue and consideration of numerous criteria. Customer evaluations, on the other hand, are a realistic means of judging the usefulness and potential drawbacks of anything because they reflect the experiences of real people like you. However, you should exercise caution when using these. Because user experiences differ from one person to the next, yours may or may not match the average. Look at as many experts and user reviews as possible to gain a more complete picture.

It is important to note that the opinions of these experts and users do not replace the advice of your doctor. Before beginning to take DIM or any other vitamins or medications, you should see your doctor. This is especially true if you have allergies, are taking any other medications, are pregnant, or are breastfeeding.

Absorption speed

The finest brands take specific steps to make absorption and dosing more consistent. The most prevalent is taking BioPerine, a black pepper extract that has been shown to enhance DIM absorption in the body. The utilization of bioavailability delivery devices is another widely used strategy.

Convenience

The ease with which you can use a product is critical to your user experience. The amount of capsules/tablets you’ll need per day, the number of times you’ll have to take it, and the flavor of the supplement are all important considerations. The suggested dose should be found in the manufacturer’s instructions. And, more crucially, double-check with your doctor.

FAQs

What is the most absorbable form of DIM?

Microencapsulated BioResponse DIM displays much higher absorption, while the generic DIM shows little absorption at all. BR-DIM® is the only DIM formulation shown to shift the estrogen metabolite ratio in clinical studies. BioResponse DIM® is the only formulation with proven absorption.

How much DIM should I take to lower estrogen?

Typical doses for premenopausal women with symptoms of estrogen dominance, which include breast pain, painful periods, excessive periods, and PMS, are from 150 to 300 mg per day. The usual dose of bioavailable, microencapsulated DIM for men is 200 to 400 mg per day taken with food.

How long does DIM take to start working?

People who use DIM supplement as a part of their weight loss program can realistically expect to see results within six weeks to six months.

What does DIM do for a woman?

DIM supplements appear to help adjust the hormone estrogen. A few clinical trials have shown that it supports healthy estrogen levels, lowering the risk of certain cancers and diseases like lupus that are linked to estrogen.

Does DIM shorten your period?

Because it affects your estrogen levels, DIM has the potential to affect your period. You could develop shorter menstrual cycles, longer periods, or have a period twice in one month. Consult with your doctor if this becomes a concern. These side effects will subside once you stop taking DIM.

Final Word

In our opinion, a good DIM supplement will contain a high-quality 450 milligram of bio-identical diindolylmethane, in the form of caff-diamine diindolylmethane. This gives your body both the I and the M forms of DIM, which will provide the best overall health benefits.
