Men have estrogen too (not just women), and the more your body has can actually decrease your testosterone levels. Olympian Labs Diindolymethane (DIM) converts strong and damaging forms of estrogen into weaker forms so your testosterone is protected and your balance of testosterone to estrogen ratio is in check. Research shows higher levels of testosterone and low levels of estrogen have been linked to lean muscle mass, an efficient fat-burning metabolism, and low abdominal fat.
