The Active Ingredient Is: Indole-3-Carbinol (I3C)

Indole-3-Carbinol is a cruciferous phytonutrient that is found naturally in veggies like broccoli and kale and is packed for supplement use.

This form is synthesised from Brassica oleracea and given in a vegetarian capsule, with a clean, simple formulation free from major allergens.

What Does Indole-3-Carbinol Do?

Indole-3-Carbinol helps with antioxidant support and may influence estrogen metabolism in a way described by EFSA and NHS-aligned literature.

Research suggests that I3C can be metabolised to active compounds that promote healthier metabolic pathways for estrogens, while providing antioxidant activity. Dr. Reed of a UK university noted a shift toward less active estrogen metabolites in supported studies.

This information reflects available mechanism-based understanding of I3C from cruciferous sources and its potential role in everyday nutritional balance.
