This study's is highlighted.

Recruitment status, easiest to join first

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 tests whether a combination of resistance-based exercise and nutritional supplements (protein and vitamin D) can improve physical function and reduce the risk of disability in older adults living in rural China. Participants are 60 years or older and show early signs of frailty, mobility decline, or nutritional risk. Over 12 weeks, some groups receive exercise training three times a week, daily supplements, or both, while others get health education or a placebo. The goal is to see if this practical program can help seniors maintain their independence.

What this could mean

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

Active substance
leucine-enriched whey protein and vitamin D
What this could lead to
If successful, this approach could offer a practical, low-cost way to help older adults maintain independence and delay disability.
What could go wrong
This is a 12-week study with 220 participants, so results may not apply to broader populations or show long-term benefits. The supplements and exercise may not work for everyone.
