Summary

This completed trial tested whether a chicken extract supplement can improve mental energy—like reducing fatigue and boosting focus—in healthy adults aged 35 to 64. Participants took a high or low dose of the supplement or a placebo daily for two weeks. The study measured attention, reaction time, and mood, along with brain activity and blood markers.

What this could mean

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

Active substance
chicken extract supplement
What this could lead to
If it works, this could point toward a natural supplement to boost mental energy and reduce fatigue in healthy adults.
What could go wrong
This is a small, early-stage study in healthy adults, so results may not apply to others. The supplement may show no benefit over placebo.
