What is Indole-3-Carbinol?
• Indole-3-carbinol (I3C) is a phytochemical derived from the enzymatic breakdown of glucobrassicin, a compound found in cruciferous vegetables such as brussels sprout, cabbage, broccoli, mustard greens, kale, and cauliflower (1).
• When raw cruciferous vegetables are chopped or chewed, glucobrassicin in the damaged plant cells breakdown by plant enzyme (myrosinase) in the stomach and small intestine (2).
• However, when cruciferous vegetables are cooked, the generation of I3C from glucobrassicin is prevented due to the inactivation of a plant enzyme. Thus, intact glucobrassicin is metabolized by bacterial myrosinase and I3C is produced in the large intestine (2).

Key Benefits of Indole-3-Carbinol
1. Estrogen balance
Indole-3-carbinol helps to promote healthy estrogen metabolism and balance by modulating the estrogen regulation cycles in several ways to decrease the risk of certain tumors (3). A study found that oral supplementation with 300-400 mg/d of I3C has significantly increased urinary 2-hydroxyestrone (2OHE) levels known as a good estrogenic metabolite (4).

2. Anti-inflammatory effects
Indole-3-carbinol helps reduce the production of inflammatory molecules, such as cytokines and prostaglandins because I3C is associated with the modulating inflammatory mediators and several signaling pathways involved in inflammation. A study showed that inflammation and oxidative damage play critical roles in cardiovascular disease and I3C is a potent cardioprotective phytochemical due to its anti-inflammatory and antioxidant effects on the cardiovascular mechanism (5).

3. Powerful antioxidant activity
Oxidative stress is known to contribute to the development of chronic diseases such as cardiovascular disease, neurodegenerative disorders, and certain cancers. Indole-3-carbinol is a powerful antioxidant reducing oxidative stress from free radicals due to the free radical neutralizing effects and can protect body cells from the oxidative reactions. By reducing oxidative stress, I3C may have potential benefits in promoting overall health and reducing the risk of chronic diseases (5).

4. Modulation of cell-signaling pathways
In cancer cells, the cell cycles including cell proliferation, apoptosis, migration, invasion, angiogenesis, and immunity are often uncontrolled. Indole-3-carbinol has positive effects on the cell-signaling pathways and its functions can support cellular health (6).

Cautions and Warnings

Consult a health care practitioner prior to use if you are taking medications or natural health products,if you are attempting to conceive, or if you have a liver disorder or symptoms of low estrogen(such as joint pain, mood changes, changes in libido, hot flashes, night sweats, vaginal dryness or irregular menstruations).
