Import Astaxanthin — Buy in Bulk from Supplier in China

Astaxanthin is a naturally occurring carotenoid pigment derived from microalgae, primarily Haematococcus pluvialis. It is recognized by CAS number 472-61-7 and is valued for its potent antioxidant properties, which are significantly stronger than those of vitamin C or beta-carotene. This food-grade product is supplied as a fine red-orange powder with a minimum purity of 1% to 5% typical, depending on the extraction method and intended application.

The compound is highly bioavailable when formulated with lipids, as its fat-soluble nature enhances absorption in the human body. Industry standards for astaxanthin include a melting point of approximately 215°C and a molecular weight of 596.84 g/mol typical. It is stable under typical processing conditions but degrades when exposed to prolonged heat or light, necessitating dark, airtight packaging. Common forms include beadlets, oils and powders, with beadlets offering improved stability for supplement formulations.

Primary applications include dietary supplements for joint health, skin protection and athletic recovery, as well as functional foods and cosmetics. Buyers in the nutraceutical industry often source astaxanthin for capsules, softgels or liquid formulations. The product is typically exported in 25 kg fiber drums with inner polyethylene bags to prevent oxidation. Importers should confirm compliance with local regulations, such as FDA in the US or EFSA in the EU, and request certificates of analysis for each batch.
