A Two-Pronged attack on sedentary aging: less sitting, more Nrf2
NCT ID NCT07792967
First seen Aug 28, 2026 · Last updated Aug 28, 2026
Summary
This trial tests whether reducing sedentary time and taking a supplement called PB125 can improve how older veterans with multiple chronic conditions respond to exercise. Researchers will measure blood vessel function, muscle strength, daily steps, and sitting time. The goal is to see if these approaches can break a cycle of inactivity and poor health.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- A behavioral program to reduce sitting and increase walking, plus a supplement called PB125 that targets the Nrf2 pathway
- What this could lead to
- If it works, this could point toward a way to make exercise more effective for veterans with multiple chronic conditions, improving strength, blood vessel health, and daily activity.
- What could go wrong
- This is an early-stage trial with a modest number of participants, so results may not apply broadly. The supplement and behavioral program may not produce meaningful changes, and any supplement carries potential side effects.
