Astazine is a branded natural astaxanthin ingredient produced by cultivating the freshwater microalga Haematococcus pluvialis under controlled stress conditions to maximize astaxanthin accumulation. Astaxanthin is a xanthophyll carotenoid with antioxidant activity reported to be significantly stronger than that of vitamin E, vitamin C, and beta-carotene. The compound is responsible for the characteristic red-orange pigmentation seen in salmon, shrimp, and flamingos. Astazine has been extensively studied for its potential benefits in eye health, skin health, cardiovascular function, and exercise endurance. It is produced using supercritical CO2 extraction to preserve the integrity of the bioactive carotenoids.
