What Is Astaxanthin?
Astaxanthin (CAS 472-61-7; INCI: Astaxanthin) is a naturally occurring keto-carotenoid widely regarded as one of the most potent antioxidants in nature. Produced primarily by the microalgae Haematococcus pluvialis and responsible for the vivid pink-red hue of salmon, krill, and flamingos, it delivers free-radical scavenging activity reported to be up to 6,000× stronger than vitamin C. VeraVita Biotech supplies high-purity natural astaxanthin (standardized oleoresin and powder grades) derived from cultivated Haematococcus pluvialis, suitable for cosmetic, nutraceutical, and functional-food formulations.
How It Works
Astaxanthin’s distinctive molecular structure — featuring both polar and non-polar end groups — lets it embed across the full width of the cell-membrane phospholipid bilayer. Unlike many antioxidants that act on one side only, it neutralizes free radicals both inside and outside the membrane while quenching singlet oxygen with exceptional efficiency. Crucially, it crosses the blood–brain and blood–retinal barriers, extending protective action to the brain and eyes where most antioxidants cannot reach.
