If you're looking to support healthy estrogen metabolism, **Diindolylmethane (DIM)** is a compound derived from cruciferous vegetables that may shift the balance toward less potent estrogen metabolites. At 100mg per tablet with a suggested range of 1-4 daily, you can adjust your intake from 100-400mg — the 100-200mg range is where most of the limited human research has been conducted.
The formula includes **Vitamin E** as d-alpha-tocopheryl succinate (33mg, a natural form) and soy **Lecithin** to support absorption, plus black pepper extract at 3mg to enhance bioavailability. What this means for you: these are practical additions since DIM is poorly absorbed on its own.
The honest caveat here: while DIM has a plausible mechanism for estrogen balance, the human clinical evidence is still limited. Most studies are small, and the research on DIM for hormone-related goals like acne, PMS, or body composition is preliminary. The soy-derived lecithin is also worth noting if you have soy sensitivities.
