Brief
Astaxanthin (CAS No. 472-61-7) is a naturally occurring carotenoid pigment renowned for its exceptionally strong antioxidant properties. It is primarily derived from the microalgae Haematococcus pluvialis and is responsible for the pink-red coloration of salmon, krill, and flamingos. Often called the “king of antioxidants,” astaxanthin is widely used in dietary supplements, cosmetics, and aquaculture for its ability to protect cells from oxidative damage and support overall health.
What is Astaxanthin?
Astaxanthin is a xanthophyll carotenoid, part of the larger carotenoid family. Unlike beta-carotene or lutein, it has a unique molecular structure that allows it to span cell membranes and neutralize free radicals both inside and outside the cell.
Because the human body does not produce astaxanthin, it must be obtained through diet or supplementation.
