Dietary Benefit
Diindolylmethane (DIM) supports the body’s ability to eliminate toxins from the liver [1], optimizes the body’s natural metabolism of hormones, and promotes good estrogen (2-Hydroxyestrone) [2]. This dietary indole antioxidant is an important factor in promoting women’s health.

Adults 100 to 200 mg per day.
Children may take up to 1/2 adult dosage.

Product Overview
In cruciferous vegetables such as broccoli, cauliflower, cabbage, and brussels sprouts, a series of compounds react when the vegetable cell walls are broken through chopping, chewing, or juicing [7]. DIM is just one of many Dietary Indoles produced in this way*. DIM is proven to have significant physiological activity [8]

DIM is stable at room temperature but must be protected from light. The highly-colored degradation products are considered beneficial and are the same as those formed in the stomach upon ingestion.
