Diindolylmethane - DIM is a hormone balancing supplement. This supplement also contains Broccoli powder, Kale powder, Black Pepper extract, rice flour and cellulose (capsule). The directions say to take 1 capsule daily with 8-12 oz of water or as directed by a physician. The company, Vitamatic, is based inthe United States, which is a plus for me. It is Non-GMO and none of the other additives you don't want. The pills are easy to swallow and have no after taste. I have not experienced any side effects. The price is reasonable. I definately recommend this supplement.
