This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
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.
Paused

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.

Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This study looks at what happens inside the body after eating broccoli sprouts. Researchers will measure changes in urine, blood, and gut bacteria in 83 healthy adults. The goal is to find biological markers that show someone has eaten cruciferous vegetables, which could help improve diet research.

What this could mean

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

Active substance
broccoli sprouts
What this could lead to
If successful, this could help researchers develop simple tests to measure whether people are eating enough vegetables, which may improve diet studies.
What could go wrong
This is a small, early-stage observational study in healthy adults, not a treatment trial. The findings may not apply to other groups or lead to any direct health benefit.

This is an AI summary of the original study and may miss details. Read our disclaimer.

Study facts

Participants

83 people

The number who actually took part.

Started

Feb 2021

Expected to finish

Dec 2027

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.
