A Smarter Approach to Hormone Balance: Understanding DIM and CDG

Written By Ingrid Huddleston

You’ve probably heard that eating cruciferous vegetables like broccoli and cabbage is good for you. One reason is that they contain compounds that support your body’s natural ability to manage hormones. Two of the most studied of these compounds are Diindolylmethane (DIM) and Calcium D-Glucarate (CDG), which are now gaining attention as a powerful supplement combination for hormonal health.

How Do They Work? A Simple Two-Step Process

Think of your body’s hormone-clearing system as a two-step process. DIM and CDG work together to support both steps.

  • Step 1: Healthy Metabolism (with DIM): After your body uses estrogen, the liver needs to break it down. DIM helps the liver convert used estrogen into more favorable, "weaker" forms, rather than more potent forms that can cause issues when they build up. 

  • Step 2: Complete Excretion (with CDG): Once the liver packages up used hormones for removal, they travel to the gut. Here, an enzyme can sometimes "un-package" these hormones, allowing them to re-enter the bloodstream. Calcium D-Glucarate works by inhibiting this enzyme, helping to ensure that the waste is fully escorted out of the body. 

By working together, DIM supports the creation of better estrogen metabolites, and CDG helps ensure they are properly eliminated.

Who Might Benefit?

This combination is for anyone looking to support their body’s natural detoxification and hormone-balancing systems. This includes both women and men who want to promote healthy estrogen metabolism. While often used for symptoms associated with hormonal shifts like PMS or perimenopause, the strongest evidence for DIM is its ability to improve key metabolic markers, not necessarily relieve specific symptoms.

Important Safety Notes

DIM and CDG are generally considered safe, but it's important to be aware of a few things. DIM can cause harmless changes in urine color and, in some people, mild headaches. Because these compounds affect hormone pathways, they should be avoided during pregnancy and breastfeeding.

Crucially, they can interact with certain medications. Anyone with a hormone-sensitive health condition or who takes prescription medication (especially hormone therapy or tamoxifen) should consult a healthcare professional before starting. 

The Takeaway

DIM and Calcium D-Glucarate offer a logical, two-pronged approach to supporting your body’s innate ability to maintain hormonal balance. While more research is always needed, they represent a targeted nutritional strategy that can be a valuable part of a holistic health plan under the guidance of a knowledgeable practitioner.

    • DIM (Diindolylmethane) – A natural compound found in cruciferous vegetables like broccoli and cauliflower. It supports healthy estrogen metabolism and helps the body maintain a balanced hormone profile.

    • CDG (Calcium D-Glucarate) – A compound that supports the detoxification of estrogen and other hormones by aiding liver and gut processes that remove excess metabolites.

    Together, these nutrients are often used in hormone balance and detox support protocols.

  • Think of DIM as helping your body process estrogen into its beneficial forms, while CDG helps your body eliminate hormone byproducts efficiently.

    • DIM – Promotes the “good” estrogen pathways and reduces potentially harmful metabolites.

    • CDG – Supports liver detox and prevents the reabsorption of metabolized hormones in the gut.

    This teamwork can contribute to hormone balance, cellular protection, and overall detox support.

  • Evidence and clinical use suggest these benefits:

    • Hormone balance – Supports healthy estrogen metabolism in men and women

    • Cellular health – Promotes protective estrogen pathways linked to breast, uterine, and prostate health

    • Detox support – Aids liver and gut function to efficiently clear hormone metabolites

  • This combination may be considered for:

    • Women with hormone-related symptoms like PMS, heavy cycles, or perimenopause concerns

    • Men and women focused on breast, uterine, or prostate health

    • Individuals on a liver detox or hormone-support plan under practitioner guidance
