Best DIM Supplements: Top Picks, Benefits, & What to Look For

What Is DIM

DIM (Diindolylmethane) is a compound formed when your body breaks down indole-3-carbinol, a substance found in cruciferous vegetables like broccoli, Brussels sprouts, cauliflower, and kale.

Yeah… mom was right, the green stuff is good for you.

It’s studied for its possible effects on estrogen metabolism, hormonal balance, acne, menopause symptoms, prostate health, and antioxidant support.

Some formulations pair it with other ingredients (e.g. BioPerine, Calcium-D-Glucarate) to improve absorption or add complementary effects. Some products for men combine it with various things to hopefully optimize good estrogen levels.

How to Choose a Good DIM Supplement

Before we dive into products, here are key criteria to consider:

• Dosage: Common doses range from ~100 mg to 400 mg or more per serving, depending on goals.
• Formulation & Bioavailability: Does it include absorption enhancers (like BioPerine or black pepper extract), or use specialized complexes (e.g. BR-DIM)?
• Add-ons: Ingredients like Calcium D-Glucarate (CDG) help with detoxification; clean manufacturing practices, non-GMO, vegan/vegetarian, third-party testing are pluses.
• Safety & Side Effects: Can cause mild digestive upset, headaches, changes in urine color. Important if pregnant, nursing, on hormone therapy, or with liver conditions.
• Cost per mg / per serving: Some bottles are more cost-effective than others. Sometimes money does buy quality, the brands Pure and Thorne come to mind. They seem worth it, but that depends on your individual situation.
