A number of studies have shown that a diet rich in cruciferous vegetables such as broccoli, Brussels sprouts, cabbage, and cauliflower can be beneficial to your health. Researchers have isolated a key component of broccoli called sulforaphane, which may have many protective properties. Sulphoraphane, an isothiocyanate, is believed to stimulate enzymes in the body. Freshly germinated broccoli sprouts contain from 30 to 50 times the concentration of isothiocyanates as mature broccoli. Source Naturals Broccoli Sprouts Extract provides 2,000 mcg of sulforaphane daily, equivalent to eating more than a pound of fresh broccoli. *
