Investigating the Bioavailability of Broccoli Extract Supplements

The goal of this clinical trial is to compare how much glucoraphanin and sulforaphane from 3 different versions of broccoli extract supplements is absorbed into the body and excreted in urine. This study involves generally healthy adults age 18-60 years. The supplements contain glucoraphanin and myrosinase enzyme, both naturally occurring in cruciferous vegetables. Once ingested, glucoraphanin is converted to the bioactive compound sulforaphane, which is thought to have numerous health benefits, including cancer prevention. Participants will: * consume 3 different versions of broccoli extract supplements (glucoraphanin will range from 35-70 mg) * complete 3 separate 24 hour study cycles * submit blood and urine samples for 24 hours * follow diet restrictions (no cruciferous vegetables or condiments or phytochemical/herbal supplements for 1 week prior to and during each study cycle)
