Olympian Labs Diindolylmethane (DIM) is a phytochemical that is a natural metabolic compound found in cruciferous vegetables such as broccoli, Brussels sprouts, and cabbage. DIM has been shown to support a healthier balance of testosterone to estrogen. This is done by converting strong and damaging forms of estrogen into weaker forms, so it does less harm to testosterone. Balancing your hormone levels can be difficult. When your estrogen and testosterone are imbalanced it can not only affect your mood but also your metabolism, how you age along with breast and prostate health. The healthy metabolism of estrogens optimizes the ratio of estrogen metabolites which is crucial for prostate health as well as for breast, uterine, and cervical health.
