TrueBroc® branded glucoraphanin is from broccoli seeds and sold as a nutritional ingredient to the food, beverage and supplement industries. The glucoraphanin is extracted from broccoli seeds using a natural, hot water process. TrueBroc® contains the highest level of glucoraphanin currently on the market.

For more than 15 years, Brassica has been manufacturing truebroc glucoraphanin for use in its own line of gourmet green and black teas as well supplying it to leading supplement manufacturers.  Most recently, the company launched a dark and light roast coffee containing TrueBroc®. Brassica is the exclusive licensee of Johns Hopkins University technology and patents as it relates to glucosinolates (ie. glucoraphanin) and isothiocyanates (ie. sulforaphane) from broccoli and other cruciferous vegetables.
