🥦 DIM and Indole-3-Carbinol: Estrogen Metabolism and Hormonal Balance
How broccoli compounds support hormonal balance
DIM (diindolylmethane) and indole-3-carbinol (I3C) are compounds from cruciferous vegetables that help balance estrogen metabolism. Let's look at their role.
What are I3C and DIM
Indole-3-carbinol (I3C) is a compound from cruciferous vegetables. In the stomach it turns into DIM (diindolylmethane), the active form that affects estrogen metabolism.
- I3C — from cruciferous.
- Turns into DIM.
- DIM — the active form.
- Affects estrogens.
Estrogen metabolism
DIM directs estrogen metabolism toward "good" metabolites (2-hydroxyestrone) instead of "bad" (16-hydroxyestrone). This supports hormonal balance.
- Boosts 2-hydroxy metabolites.
- Reduces 16-hydroxy metabolites.
- Supports balance.
- Useful for estrogen dominance.
Breast health
DIM and I3C are studied for breast health support in estrogen dominance. They help balance the hormonal background.
- Breast support.
- Estrogen balance.
- Useful in fibrocystic changes.
- Promising data.
Prostate
DIM also supports prostate health in men, affecting hormone balance and reducing pro-inflammatory pathways.
- Prostate support.
- Hormone balance.
- Reduces inflammation.
- Useful for men.
Food sources
| Food | I3C content | Comment |
|---|---|---|
| Broccoli | High | Cruciferous |
| Cabbage | High | Cruciferous |
| Cauliflower | Medium | Cruciferous |
| Brussels sprouts | Medium | Cruciferous |
| Watercress | Medium | Cruciferous |
Dosages
| Substance | Dosage |
|---|---|
| I3C | 200–400 mg/day |
| DIM | 100–300 mg/day |
Practice
- Eat cruciferous vegetables (broccoli, cabbage).
- For balance — DIM 100–300 mg/day.
- Take with fatty food.
- Combine with fiber for elimination.
- Consult a doctor.
What is DIM?
Diindolylmethane — the active form of indole-3-carbinol that affects estrogen metabolism.
How does DIM affect estrogens?
It directs metabolism toward "good" 2-hydroxy metabolites.
Does it help with PMS?
Yes, in estrogen dominance it may reduce PMS symptoms.
How much to take?
I3C 200–400 mg/day, DIM 100–300 mg/day.
Where is I3C found?
Broccoli, cabbage, cauliflower, Brussels sprouts, watercress.
Is it good for the prostate?
Yes, DIM supports prostate health and hormone balance.
Can it be obtained from food?
From cruciferous, but supplements are needed for effect.
How to take it?
With food containing fats for better absorption.
Is DIM safe?
In normal doses yes, but with hormonal therapies a doctor is needed.
When is a doctor needed?
With hormonal therapies, cancer and growths.
