3,3'-Diindolylmethane (DIM) comes from broccoli, cabbage, and other cruciferous vegetables. People take it to help the body process estrogen in a healthier way, which supports overall hormone balance. Men and women both use it, and clearer skin can follow when hormones level out, which is why those dealing with hormonal acne sometimes reach for it.
Take DIM once or twice a day with a meal that contains fat. Fat helps your body absorb it. Results build over time, so don’t skip days.
Be careful if you have a hormone-sensitive condition. DIM can shift how thyroid meds and certain hormone drugs work in your body. Skip it if you’re pregnant or nursing.
