Summary

This pilot study tested whether a dietary supplement containing fiber and green tea extract could increase feelings of fullness from alcohol in 64 at-risk drinkers. Participants took either the supplement or a placebo before drinking alcohol in a lab setting. The goal was to see if the supplement could reduce the desire to drink more by boosting satiety.

What this could mean

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

Active substance
dietary fiber (Fibersol-2) and decaffeinated green tea extract
What this could lead to
If it works, this could point toward a simple supplement that helps people feel fuller from alcohol, possibly reducing how much they drink.
What could go wrong
This is a small, early pilot study with only 64 people. The supplement may not actually change drinking behavior in real-world settings, and results may not apply to everyone.
