In preclinical studies, DIM has been shown to lead to the preferential formation of estrogen metabolites that are correlated with healthy breast, endometrial, and cervical tissues. This unique property sets DIM apart from other plant nutrients. Source Naturals DIM is formulated with phospholipids, vitamin E and BioPerine®.*
