Clinical Context
Park et al. showed oral astaxanthin is absorbed dose-dependently in dogs and cats, with substantial localization in leukocyte mitochondria. That makes it a rare two-species antioxidant anchor.

WHAT
Astaxanthin is a naturally occurring carotenoid antioxidant that helps protect cells and tissues from oxidative stress. It is produced by microalgae (Haematococcus pluvialis) and is responsible for the red-orange color of salmon and other marine organisms, where it plays a role in protecting cells from damage caused by reactive oxygen species.
