Can a vitamin B3 pill help older veterans stay stronger longer?

NCT ID NCT04691986

First seen Nov 01, 2025

Summary

This study tests whether nicotinamide riboside (NR), a form of vitamin B3, can improve muscle strength, endurance, and walking speed in older veterans aged 65-85. Participants take NR or a placebo daily for several weeks and undergo exercise tests and muscle biopsies. The goal is to see if boosting NAD+ levels can slow age-related muscle decline and frailty.
