Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a randomized, placebo-controlled interventional trial comparing broccoli sprout extract to an inactive placebo over 12 weeks. Participants take the extract or placebo daily and attend visits at screening, baseline (week 0), week 6, and week 12 for cognitive testing and safety checks. Investigators will track changes in cognitive function and record any side effects during the treatment period. Eligibility requires absence of dementia and ability to read Korean, with investigators able to exclude unstable medical conditions.
