Simple home workout and protein shake may keep seniors on their feet

Summary
This study tested whether a simple home exercise program and protein supplements, alone or together, could help prevent falls in seniors at risk of muscle loss (sarcopenia). Over 800 older adults with early signs of frailty or a recent fall took part. They were assigned to do strength or flexibility exercises and take either a protein or a placebo powder. The goal was to see if these easy-to-do steps could reduce falls and maintain independence.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Protein supplement (Moltein® Ready-to-Shake) and home exercise program
- What this could lead to
- If successful, this could provide a simple, low-cost way for seniors to reduce fall risk and maintain muscle strength as they age.
- What could go wrong
- The study is completed but results are not yet widely confirmed. Benefits may vary depending on individual health and adherence to the program.
