Summary

This pilot study is testing whether taking 24 grams of whey protein daily for three months can improve brain antioxidant levels, physical function, and thinking skills in pre-frail adults aged 65 to 85. Twenty participants will be randomly assigned to receive either whey protein or a calorie-matched placebo powder. The goal is to see if a simple dietary supplement can help slow or reverse the signs of frailty.

What this could mean

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

Active substance
whey protein
What this could lead to
If it works, this could point toward a simple dietary supplement to help older adults maintain strength and brain function as they age.
What could go wrong
This is a very small pilot study with only 20 participants, so results may not apply to everyone. It is too early to know if whey protein truly helps.
