Summary

This study planned to test whether sulforaphane, a compound found in broccoli, could improve social skills and behavior in people with autism spectrum disorder (ASD). Researchers aimed to enroll 50 people with ASD aged 12–34 and 30 healthy volunteers, giving the ASD group sulforaphane tablets daily for 8 weeks. However, the study was withdrawn before any participants were enrolled, so no results are available.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: sulforaphane (a compound from broccoli and other cruciferous vegetables)
What this could lead to: If it had worked, this could have pointed toward a dietary supplement to help ease social and behavioral symptoms in autism.
What could go wrong: The study was withdrawn before enrolling anyone, so no data were collected. Even if it had run, it was small (50 participants) and short (8 weeks), making it too early to draw firm conclusions.
