Protein powder fails to prove recovery boost in tiny hip fracture trial
NCT ID NCT04306536
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This small trial tested whether adding a special protein-and-vitamin powder to the diet could help older adults walk better after surgery for a broken femur. Only 20 people took part, and the study was stopped early. The main goal was to see if the supplement improved walking speed, but the early termination means we cannot draw firm conclusions.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Fortifit (a protein, vitamin, and mineral powder supplement)
- What this could lead to
- If it worked, this could point toward a simple nutritional strategy to improve physical recovery after hip fracture surgery in older adults.
- What could go wrong
- The trial was terminated early and enrolled only 20 people, so results are very limited. It is unclear if the supplement provides any real benefit over standard diet.
