Frequently Asked Questions

Q1: What's the difference between Astaxanthin 1%, 2%, and 5%?

The 1%/2%/5% difference reflects total Astaxanthin content measured via HPLC. 5% is positioned for premium and pharmaceutical applications. 1-2% beadlets are common for supplement formulations.

Q2: What's the difference between natural and synthetic Astaxanthin?

Natural Astaxanthin is produced via Haematococcus pluvialis microalgae cultivation (predominantly 3S,3'S-isomer). Synthetic Astaxanthin is chemically produced (3R,3'R / 3R,3'S isomers). Natural is the form used in dietary supplements.

Q3: Can Astaxanthin be combined with other antioxidants?

Astaxanthin is commonly combined with Vitamin E, Vitamin C, and other carotenoids (lutein, zeaxanthin) for synergistic effects. We recommend consulting with your formulation team.

Natural Astaxanthin from Haematococcus pluvialis is permitted as a food supplement ingredient in the EU under Novel Food Regulation 2015/2283. Specific regulatory status depends on intended application and labeling.

Q5: How is Astaxanthin content measured?

Astaxanthin content is quantified via HPLC per USP method with UV-Vis detection at 474 nm.

Q6: What's the typical MOQ?
