Astaxanthin is a carotenoid, a red-orange pigment of the xanthophyll group produced by microalgae and responsible for the colour of salmon and shrimp that feed on them. The Celyfe compound library classes it as a potent carotenoid antioxidant with an oral delivery route. It is not carried in any Celyfe pen.
What is astaxanthin?
Carotenoids are a class of plant and algal pigments, and astaxanthin belongs to the oxygen-containing subgroup called xanthophylls. It is synthesised by certain microalgae and accumulates in the animals that eat them. The Celyfe library lists it as a carotenoid with the mechanism note: potent carotenoid antioxidant. It is not a peptide and not a regulated compound.
Is astaxanthin in a Celyfe pen?
No. None of the four pens carries astaxanthin. The compound-library entry is there for chemical reference, to show where a carotenoid antioxidant sits relative to the peptides and the polyphenols. Celyfe does not currently sell astaxanthin as a product and lists no astaxanthin reference, so this page makes no statement about research findings.
