Indole-3-carbinol (I-3-C) is a phytonutrient found in Brassica vegetables such as broccoli, kale and cabbage, and is one of the key health-promoting compounds in these foods. Many studies have had phenomenal success using I-3-C to shift the balance of metabolic enzymes that process estrogens thereby reducing the formation of “bad” estrogens and increasing the formation of “good” estrogens. Human studies in women taking I-3-C have shown a favourable shift in estrogen metabolism, and I-3-C has been shown to be protective against estrogen dominance. Estrogen dominance has been linked to fibroids, breast tenderness, premenstrual syndrome, endometriosis and other women’s health concerns.

Women who are concerned with safer estrogen metabolism, who have a family history or increased risk of estrogen-dependent cancers, or those that have a higher ratio of bad to good estrogens can benefit from this product. I-3-C may also be a beneficial supplement for those who want to reap some of the benefits of Brassica vegetables but have difficulty eating them raw.
