NCT ID NCT05483465

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study tests whether a daily dose of nicotinamide riboside (a form of vitamin B3) can improve blood flow and activity in the brains of healthy adults aged 60 to 85. Over 8 weeks, 214 participants will take either the supplement or a placebo. Researchers will measure brain blood flow and electrical activity to see if the supplement helps keep the aging brain healthier.

What this could lead to
If it works, this could point toward a simple supplement to help maintain brain health and memory in older adults.
