What is Astaxanthin?
Astaxanthin is a carotenoid pigment that occurs naturally in certain algae and is responsible for the pinkish-red color in seafood such as salmon, shrimp, and krill. It is renowned for its powerful antioxidant properties, which are believed to support skin health, eye health, and combat inflammation. Due to these properties, astaxanthin is frequently used in dietary supplements and as a natural food colorant in various products.

Diet Compatibility
Astaxanthin is a red-orange carotenoid pigment found naturally in algae, krill, and seafood, and is often used as a dietary supplement or food colorant due to its antioxidant properties. Astaxanthin should be avoided on a corn-free diet when it is produced via fermentation processes that utilize corn-derived glucose or other corn-based feedstocks, as trace residues may be present in the final product. Please contact the manufacturer for details.

Why People Avoid Astaxanthin
People on a corn-free diet may avoid astaxanthin when it is produced using fermentation processes that involve corn-derived glucose or other corn-based feedstocks. Even though the final product may contain only trace residues, these can be enough to trigger sensitivities in highly corn-sensitive individuals. To ensure a product is truly corn-free, it is recommended to contact the manufacturer for specific production details.
