Sulforaphane is a compound that was identified in broccoli sprouts by scientists at the Johns Hopkins University School of Medicine in Baltimore, MD.1
How It Works
How to Use It
The optimal level of intake is not known, but some doctors recommend 200 to 400 mcg of sulforaphane daily from broccoli-sprout extracts.
Where to Find It
Sulforaphane is found in highest concentrations in broccoli sprouts, but it is also found in mature broccoli and other cruciferous vegetables, such as cauliflower, cabbage, and kale.
Sulforaphane is not an essential nutrient, and thus no deficiency state exists.
Interactions with Supplements, Foods, & Other Compounds
Sulforaphane and dietary consumption of cruciferous vegetables does interact with drug detoxifying enzymes.2 People taking prescription drugs should therefore consult a doctor before taking sulforaphane or broccoli-sprout extracts.
