Astaxanthin (AXT) is a xanthophyll carotenoid recognized as one of nature's most potent antioxidants. It exhibits significantly greater free-radical scavenging activity than beta-carotene, vitamin C, and vitamin E. It is primarily sourced from Haematococcus pluvialis microalgae through controlled cultivation and extraction processes.

In the B2B ingredients market, astaxanthin is a high-value functional ingredient used across supplement, cosmetic, and food industries. Its strong antioxidant capacity supports applications in joint health, skin health, cardiovascular support, and eye health formulations.

We supply natural astaxanthin in multiple concentrations and formats including powder, oleoresin, and beadlet forms to meet diverse manufacturing requirements for softgel, capsule, tablet, and functional food production.
