How it works
Protects brain cells from oxidative damage and supports long-term cognitive health.
Overview
Astaxanthin is primarily valued for its antioxidant capacity, which is significantly stronger than many other carotenoids. While it does not produce immediate cognitive effects, it plays an important role in long-term brain health and cellular protection. It is often used alongside omega-3 fatty acids to support overall neurological function. Its benefits are preventative and cumulative rather than performance-driven.
