Ultra I-3-C
Ultra I-3-C, provided by Douglas Laboratories®, supplies significant amounts of indole-3-carbinol (I-3-C) in a proprietary blend of cruciferous vegetables for healthy hormone balance and cellular health.
Functions
Indole-3-carbinol is a member of the class of sulfur-containing chemicals called glucosinolates, phytochemicals found in high amounts in cruciferous vegetables such as broccoli, cauliflower, and Brussels sprouts. Indole-3- carbinol functions as an antioxidant, stimulates natural detoxification enzymes and supports normal hormone metabolism.
Furthermore, I-3-C supports the function of healthy breast and cervical cells. In recent years, I-3-C has shown a promising ability to support prostate cell metabolism. In the stomach, indole 3-carbinol must be broken down into its active metabolite diindolylmethane, another indole compound that also has similar health benefits.
Indole-3-carbinol supports healthy estrogen metabolism by promoting a healthy ratio of weak estrogens (2-hydroxyestone metabolites or 2-OHE) to strong estrogens (16 alpha-hydroxyestrone metabolites or 16 alpha-OHE) in favor of the weak, less potent estrogens. Indole-3-carbinol also induces phase II enzymes including glutathione S-transferase (GST).
Cruciferous vegetables like broccoli and cauliflower offer protective sulforophane compounds known for their ability to induce protective detoxifying enzymes.
Indications
Ultra I-3-C may be a useful dietary supplement for individuals wishing to supplement their diet with indole-3-carbinol to support healthy estrogen metabolism.
