Whey to go? protein drink tested to fight frailty in seniors
NCT ID NCT07167277
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
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.
