Astaxanthin May Protect Aging Brains and Livers by Calming Oxidative Stress

Based on: Nrf2/Bach1-ARE pathway are involved in the ameliorative effects of astaxanthin on D-galactose-induced liver and brain aging and injury.

Preliminary Evidence·Journal Article·Scientific reports·May 2026

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.

Key Insight

This animal study suggests astaxanthin may support brain and liver health by boosting the body's antioxidant defenses.

Birth Control and Hormone Therapy May Leave a Lasting Mark on Women's Brains

In women aged 65 to 80, those who had used birth control pills earlier in life had more gray matter in several brain regions. Combining birth control with menopausal hormone therapy was linked to even greater volume and thicker cortex. Later menopause, meaning more natural hormone exposure, also tracked with healthier brain structure. Timing of hormone exposure may matter for long-term brain aging.
