I don't have the technical skills, equipment and a team of analysts who can say definitively if this is a great product. It ISN'T going to make anyone FEEL better, or differently. It's simply not that type of suppliment. People who take this are trying to avoid harmful female estrogens (there are many types, not just "estrogen"). This is a factor in female reproductive health as well as in men who's RATIOS of estrogen/testosterones become skewed as they age (the testosterone decreases with age). Read the online article for detailed info: "What about DIM?" I take it for prostate health, and to slow the onset of BPH. Since I'm a bit paranoid as to whether any one company makes the best DIM I alternate the Bronson Brand with another similar product made at a different company. So like I said at the beginning, I don't have the tools to analyze this and make a recommendation. But I'm happy with my "health" now, so I'm going to continue to take it for the rest of my life. Kind of like taking Omega 3s (fish oil); I've been taking it since I was 18 ! I'll be 70, next year.
