About Broccoli & Indol-3-Carbinol
Broccoli (Brassica oleracea var. italica) is one of the oldest cultivated vegetables, originating in Italy and valued since Roman times for its unique flavor and nutritional profile. As a member of the cruciferous family, broccoli naturally contains Indol-3-Carbinol, a phytochemical studied for its antioxidant and hormone-balancing properties.
Natural I3C from broccoli seed extract is rare on the market. Our specialized extraction process concentrates the I3C naturally present in the seeds—without requiring carriers or fillers.

Marie D., Belgium –
After years of feeling tired, bloated and just ‘off’—especially before my period—I was ready to try anything. My doctor said everything was ‘normal’, but I knew my body wasn’t right. A friend in Brussels told me about Indol-3-Carbinol from broccoli seeds, and that’s how I found immunesupp.com.
I started with two capsules a day with lunch, just like the label says. After three weeks I noticed I had more energy, less swelling, and my mood was much more stable. By the second month, the heavy, uncomfortable days were finally manageable again. I’m so grateful I discovered this clean, simple formula—no strange additives, just pure broccoli seed extract.
If you’re a woman struggling with hormonal balance, PMS, or just feeling run down, I truly recommend trying this. It’s not magic, but for me it made a real difference. Merci, immunesupp.com!
