Mechanism of action

1

Membrane-spanning antioxidant

The astaxanthin molecule sits across the full width of the cell membrane, letting it neutralize free radicals at both surfaces, a structural advantage over many antioxidants.

2

Anti-inflammatory signaling

Astaxanthin downregulates inflammatory mediators and supports antioxidant enzyme systems, contributing to its skin, eye, and recovery effects.
