Primary outcomePrimary: Sulforaphane Bioavailability Measured in Sequential 12-Hour Urine Samples — 24.8; 11.0; 4.3 micromoles/24 hours — p=<0.001
Summary
This study will examine the extent to which lower doses of a broccoli-derived beverage enhance the detoxication of air pollutants excreted in urine as compared to an maximal dose shown to be effective previously.
