Sulforaphane

Uses

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.

Possible Deficiencies

Sulforaphane is not an essential nutrient, and thus no deficiency state exists.

Interactions

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.
