What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.

Summary

This study tests whether taking a broccoli sprout extract (sulforaphane) for four days, doing high-intensity interval running, or combining both can improve how immune cells use energy and reduce inflammation. Twenty healthy adults aged 18-35 will try each approach in random order, with a week break in between. Blood samples are taken before and after each period to measure changes in cell metabolism and inflammatory markers.

What this could mean

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

Active substance
sulforaphane-rich broccoli sprout extract
What this could lead to
If it works, this could point toward simple lifestyle or supplement strategies to boost immune and metabolic health.
What could go wrong
This is a very small, early-stage study in healthy young adults, so results may not apply to older or less healthy people. The 4-day intervention is too short to show lasting effects.
