NCT ID NCT07379437

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study tests whether astaxanthin, a natural substance from algae, can slow brain aging in adults aged 50 and older. Over 6 months, 120 participants will take either a low or high dose of astaxanthin or a placebo. Researchers will measure changes in memory, thinking, brain scans, and blood markers to see if the supplement improves mitochondrial function and reduces oxidative stress.

What this could mean

What this could lead to

If it works, this could point toward a simple dietary supplement to help maintain cognitive function in older adults.

What could go wrong

This is an early-stage trial with only 120 people, so results may not apply to everyone. The supplement may show no benefit over placebo.
