Product Introduction
Astaxanthin is a lipophilic xanthophyll carotenoid extracted from the microalgae Haematococcus pluvialis. It inserts stably into the lipid bilayer of cell and mitochondrial membranes, enabling bidirectional neutralization of both water‑soluble and fat‑soluble reactive oxygen species (ROS). It quenches singlet oxygen, inhibits lipid peroxidation, reduces oxidative stress, and stabilizes membrane integrity. It crosses the blood‑brain barrier and blood‑retinal barrier to protect neural and retinal tissues from oxidative and blue‑light‑induced damage. It also modulates redox‑sensitive transcription pathways including Nrf2 and NF‑κB to support anti‑inflammatory and cytoprotective responses.
