Algae power: could this supplement keep your brain young?
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.
