This is a hormone-support formula built around **DIM** (diindolylmethane), the cruciferous-vegetable compound studied for nudging estrogen metabolism toward its more protective pathway. You're getting 200mg per capsule, which lands squarely inside the 100-300mg range used in clinical trials, so on dose alone that's a real, studied amount.

Two things the label doesn't tell you matter here. First, nearly every DIM trial used a microencapsulated, phospholipid-carried form (BioResponse DIM) that absorbs far better than plain crystalline DIM; the form isn't specified here and there's no lecithin or piperine to aid uptake, so how much you actually absorb is an open question. Second, the research itself is limited: DIM reliably shifts an estrogen biomarker, but harder outcomes like symptom relief or disease prevention haven't been proven.

The supporting ingredients trail their studied doses. Calcium D-Glucarate is included at 100mg, below the 200mg floor of its supplemental range, and its human evidence is essentially preclinical. Chlorophyllin at 20mg sits well under the 100-300mg used in research, where it was studied for binding toxins rather than hormonal support. What you're really paying for here is the DIM.
