Summary

This study tested whether a daily supplement called ETAS®, made from asparagus, could improve memory, mood, and reduce inflammation in healthy adults aged 60-80 who had mild memory concerns. 45 participants took either a low or high dose of ETAS® or a placebo for 12 weeks. Researchers measured cognitive function, mood, and blood markers of inflammation to see if the supplement had any effect.

What this could mean

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

Active substance
ETAS® (a dietary supplement derived from asparagus)
What this could lead to
If it works, this could point toward a natural supplement to help maintain brain function and reduce inflammation in older adults with mild memory complaints.
What could go wrong
This is a small, early feasibility study with only 45 participants. Results may not apply to everyone, and any benefits might be small or not clinically meaningful.
