DIM is one of the most searched supplements in fitness, and one of the most misunderstood. Here's what it actually does, who it's for and how to fit it into your stack.
What is DIM?
DIM (3,3'-diindolylmethane) is a compound your body makes when you digest cruciferous vegetables like broccoli, kale, cabbage and cauliflower. Getting a meaningful amount from food alone would take a lot of broccoli every day, which is why people take it as a capsule.
What it does
DIM supports healthy estrogen metabolism. In simple terms, it influences how your body breaks estrogen down, favouring one pathway over another. That's it. It doesn't block estrogen, and it isn't a testosterone booster, whatever you've read online.
Who it's for
| Who | Why they take it |
|---|---|
| Men who train hard, especially during a cut or later in life | To support healthy estrogen metabolism |
| Women who want to support hormone balance | To support healthy estrogen metabolism |
| People who rarely eat cruciferous vegetables | A concentrated source of what those vegetables provide |
Who should skip it or ask a doctor first
Skip DIM if you're pregnant or breastfeeding. Talk to your doctor first if you take medication, use hormone therapy or have a hormone-sensitive condition.
How to take it
- Take it with a meal that has some fat in it, since DIM is fat-soluble.
- Be consistent and give it several weeks.
- Darker urine is a common, harmless side effect.
How to stack it
- DIM + MULTI-V: your daily foundation, taken together with breakfast.
- DIM + CLEAN GREENS: greens covers the broader fruit and veggie gap, and DIM is the concentrated cruciferous piece.
- The training stack: DIM and creatine as your daily non-stim base, with VANDAL or VIPER before training.
Myths to drop
- "DIM raises testosterone." That's not what it does.
- "DIM kills estrogen." You need estrogen. DIM supports how it's metabolized, it doesn't remove it.
- "More is better." Stick to the label dose.
Shop DIM: 100 mg per vegetarian capsule.
