How are we different?

Our indole-3-carbinol is obtained via a custom extraction method from broccoli using pure ethanol. The final product has an indole-3-carbinol content of 99%+, allowing for a full 300mg indole-3-carbinol per capsule.

Usually, high doses of conventional, natural indole-3-carbinol are achieved via two extraction steps. Since solvents such as methanol, toluene, benzene are commonly used in the first step, we have decided to source our indole-3-carbinol from synthetic production followed by pure ethanol extraction. Therefore, unlike many similar products on the market, it is obtained completely without the use of methanol, benzene and toluene. The result is a final product which is non-GMO and contains no allergens or further additives.

For the capsule shells we use custom-made HPMC capsules that, unlike most other HPMC capsules that can be found on the market, are 100% free from controversial additives such as carrageenans and PEG. We use environmentally friendly amber glass jars for the packaging of this product.

Broccoli, which is native to Italy, has been cultivated since Roman times, which is why it is also sometimes referred to as Italian brassica (Brassica oleracea italica). It belongs to the cruciferous family (Brassica oleracea) and, like all cruciferous plants, is descended from wild cabbage. The name broccoli is derived from the Italian word "brocco," meaning "sprout" or "shoot," and refers to the typical structure of broccoli inflorescences, which grow out of a single, compact shoot.

There is literary evidence to suggest that broccoli was cultivated as early as 6,000 years ago, making it potentially the oldest cultivated vegetable. Cabbage played an important role in ancient times and in the Middle Ages, and the Romans valued broccoli plants for their distinctive look and unique aroma. Broccoli spread from Italy to the rest of the world in the 19th and 20th centuries, and nowadays enjoys great popularity due to its relatively mild taste compared to other cruciferous vegetables.

Among the most important mustard oils found in broccoli is indole-3-carbinol.
