Summary

This phase 2 trial tests whether sulforaphane, a compound found in broccoli, can improve core symptoms of autism. 48 males aged 13-30 with autism will receive either sulforaphane or a placebo for several weeks. Researchers will measure changes in behavior and social responsiveness using standard scales.

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 works, this could point toward a dietary supplement that eases core autism symptoms like social interaction and behavior.
What could go wrong
This is a small, early-phase trial with only 48 males, so results may not apply to everyone. Sulforaphane may cause no improvement or side effects like changes in liver or kidney function.
