Vitamin d pills tested as muscle saver for seniors with obesity
NCT ID NCT07275177
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether taking a high dose of vitamin D3 daily for 12 weeks could improve muscle strength and mass in older adults with obesity. Researchers enrolled 29 participants aged 60 and older in southern Mexico. They measured handgrip strength, muscle mass, and physical performance before and after the supplement period. The goal is to see if correcting low vitamin D levels can help prevent age-related muscle decline.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- Vitamin D3 (cholecalciferol)
- What this could lead to
- If it works, this could point toward a simple, low-cost way to help older adults with obesity maintain muscle strength and physical function.
- What could go wrong
- This is a small, completed study with only 29 participants, so results may not apply to everyone. Vitamin D supplements may not significantly improve muscle health in all older adults.
