As of 2025, randomized controlled trials of sulforaphane-rich preparations in humans have demonstrated changes in surrogate biomarkers, such as reduced bronchial epithelial Ki-67 in former smokers,[6] altered prostate-specific antigen kinetics in men with biochemical recurrence of prostate cancer,[7] and increased urinary excretion of airborne pollutants such as benzene and acrolein.[8] Small clinical studies have also reported possible improvements in some symptoms of autism spectrum disorder,[9] although later reviews found the results inconsistent and not conclusive.[10] Despite these findings, no clinical trial has shown that sulforaphane reduces the actual incidence, progression, or mortality of cancer or other diseases, and overall clinical evidence remains limited and inconclusive.[11]
