Astaxanthin May Protect Aging Brains and Livers by Calming Oxidative Stress
Key Insight
This animal study suggests astaxanthin may support brain and liver health by boosting the body's antioxidant defenses.
In rats given a chemical that speeds up aging, astaxanthin (the red pigment in salmon and shrimp) reduced damage to the brain and liver. It worked about as well as vitamin E and improved memory in the water maze test. The benefits disappeared when researchers blocked a specific antioxidant pathway, confirming how it works.
