This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

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.
