The world of supplements is a confusing one. There are so many supplements out there, so many miracle cures, so many brand names, so many products that it's almost impossible for a regular person, even a highly intelligent one, to sort through all of the information and make an informed decision about which supplements are effective and which are safe. If you've landed on Diindolylmethane (DIM) as a possible antidote to conditions and issues related to hormone imbalance, then you know that it has been used quite effectively to prevent cancer and balance sex hormones. There is, however, the lingering question…is it safe? The best way to answer this question is to understand what DIM is and how it works.
