Overview

In plain language

Astaxanthin is a powerful carotenoid antioxidant derived from microalgae that gives salmon and shrimp their pink color. It crosses the blood-brain and blood-retinal barriers, providing unique protection for the eyes and brain.

Naturally found in salmon and microalgae, astaxanthin is known as one of the most potent natural antioxidants. It reduces oxidative inflammation, enhances endurance, supports healthy skin aging, and improves eye health. Seniors benefit from its role in protecting heart and cognitive function while reducing fatigue.
