Product Overview

Nutritional supplements containing Dietary Indoles have been marketed since 1990. 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 [10]. A wide variety of Dietary Indoles are produced in this way*. Dietary Indoles have significant physiological activity [11].

Designed Nutritional Products offers the only broccoli powder product standardized to 25% Dietary Indoles. Brox-25 includes Ascorbigen, Diindolyl-methane (DIM), and Indole-3-Carbinol (I3C). A few capsules will deliver the same Dietary Indole benefit as several pounds of cruciferous vegetables.


Dietary Benefit

Brox-25 contains 25% of mixed dietary indoles. Dietary indoles support the body’s ability to eliminate toxins from the liver [1], optimize the body’s natural metabolism of hormones, and promote good estrogen (2-Hydroxy-estrone) [2,3]. Dietary indoles are important factors in promoting women’s health [4-9].



400-1600 mg daily



Most Dietary Indoles are heat and/or light sensitive. The degradation products of Dietary Indoles are considered beneficial and are the same as those formed in the stomach upon ingestion.



Dietary Indole blend. No CAS Registry Number available.


Regulatory Status

Dietary Indoles are dietary supplements under provisions of US Dietary Supplement Health and Education Act of 1994 (DSHEA).
