8 Best DIM (Diindolylmethane) Supplements (2023) Reviewed and Compared

Never miss a glorious update - click here!

DIM (Diindolylmethane) is a supplement known for helping balance your main sex hormones: testosterone and estrogen. This, in turn, may have array of benefits, from treating hormonal acne, to alleviating PMS symptoms, to support energy levels and gym performance.

In this article, we’ll discuss if DIM is worth its hype and the best DIM supplements on the market.

What is DIM (Diindolylmethane)?

When you eat and digest cruciferous vegetables, such as broccoli, cauliflower, or brussel sprouts, your body creates a compound called DIM (Diindolylmethane), after which it digresses into another compound called indole-3 carbinol.

(Don’t worry, we’re done with the confusing chemistry terms now. )

Studies have shown that this compound might reduce the risk of developing certain cancers. It also might help manage levels of estrogen in the body.

You can obtain DIM from eating cruciferous vegetables but, in order to get its full health benefit, you would need to eat multiple servings each day. This is why a supplement can be both a handy and effective way to get some DIM into your diet. As a supplement, it may also be useful for targeting certain conditions.

In its supplement form, the recommended dose for DIM is 100 mg to 900 mg.

What Are the Benefits of DIM Supplements?

“Okay, well why you I take a dim supplement?” you may be asking.

First, DIM has been shown to have anticancer effects.

For instance, one study showed that taking 300 mg of DIM for a year increased two types of estrogen levels that may reduce the risk of breast cancer in its participants. Another study found that DIM could potentially be used as a preventative against prostate cancer.

There have been other studies that suggest taking a DIM supplement can protect against ovarian cancer, but more human research is needed.

DIM has also been suggested to help with weight loss, but this is mostly speculative and as a result of improved hormonal balance.

In fact, there is no research that examines DIM’s role in weight loss. However, there are studies that show how unbalanced estrogen levels in the body can lead to weight gain and weight fluctuation. Therefore, managing estrogen levels may help people maintain a healthy weight.

Support Hormone Balance

In a similar light, taking a DIM supplement might help with other hormonal disorders. While there isn’t currently evidence to support this claim, existing studies show that estrogen levels play a significant role in hormonal issues like acne and PMS. A DIM supplement, therefore, might help balance the hormones causing these issues.

If you struggle with hormonal-related issues such as weight gain, PMS, or acne, or you want to take preventative measures against certain cancers, a DIM supplement might be worth the try.

It can also help with hormone-related hot flashes and mood swings.
