Indole-3-carbinol (I-3-C): Secondary plant substances for cell protection
Diseases do not always come from outside: Aggressive chemical compounds in the body can also cause great damage to our cells. But the organism is not at the mercy of them: Antioxidants, also called radical scavengers, inhibit the harmful oxidation of cell structures. In test studies, they were able to help neutralize this dangerous process.

Some phytochemicals are particularly effective free radical scavengers, including resveratrol and quercetin. These are contained as an active ingredient combination in the preparation indole-3-carbinol (I-3-C). Both are obtained from the Japanese knotweed (Polygonum cuspidatum). Resveratrol is one of the valuable phytoalexins that plants produce as natural antibiotics for microbial infections. Both plant substances are said to have an anti-inflammatory effect in various studies.

Indole-3-carbinol, which gives the product its name, is extracted from various cruciferous vegetables such as cauliflower, kale, Brussels sprouts and broccoli. Experimental laboratory studies have shown that ingredients from types of cabbage inhibit the reproduction of certain cancer cells and can support the effects of chemotherapy and estrogen blockers, for example in breast cancer.
