Community experiences

Selected positive personal experiences from external communities, edited and summarized. These accounts do not establish effectiveness.

A contributor who used DIM powder wrote that their usual low mood and premenstrual mood symptoms eased, along with other PMS discomfort. They used it under a naturopathic practitioner's guidance and selected a duration of at least one but less than two years in the review. Their description of their hormone status was not supported by test results, and no other treatment details were given; the account does not demonstrate treatment of depression or PMDD, or correction of hormone levels.

Experience shared by external community contributor A

A contributor who took DIM for cystic acne wrote that their skin looked better than it had in a long time. However, they also had irritable bowel syndrome and reported severe diarrhea every day during use, which meant they could not continue taking it. This account includes both a perceived skin improvement and discomfort that prevented continued use; it is not a recommendation to do the same based on the skin result alone.
