Frequently Asked Questions
What is astaxanthin used for?
Astaxanthin (CAS 472-61-7) is a red-orange xanthophyll carotenoid used primarily as a pigment in salmonid and crustacean aquaculture feed, where it imparts the characteristic pink/red color in farmed salmon and trout. It is also used as a carotenoid colorant across feed, food, and cosmetics. RawSource supplies it in bulk to feed and ingredient manufacturers.
What is astaxanthin made from?
Astaxanthin is a carotenoid pigment with formula C40H52O4. Commercial supply is produced by microalgae fermentation (notably Haematococcus pluvialis), yeast, or chemical synthesis depending on grade. Source and form affect specification, so confirm the production route on the CoA for a given lot.
Is astaxanthin natural or synthetic?
Both natural and synthetic astaxanthin are available commercially. Natural grades are derived from microalgae or yeast; synthetic grades are chemically manufactured and are common in aquaculture feed. RawSource can quote the form that matches your formulation and labeling requirements.
