AstaReal® P4AF is made in the USA from cultivation to extraction. The algae are cultivated in our proprietary fully enclosed indoor cultivation facility in Moses Lake, WA. Indoor cultivation allows optimal algal productivity and harvest timing for best astaxanthin content and stability. AstaReal® P4AF is then extracted from whole algae using a solvent free supercritical fluid carbon dioxide extraction method. AstaReal® Astaxanthin is then extracted from whole algae using a solvent free supercritical fluid carbon dioxide extraction method. The resulting natural astaxanthin oil contains 10% AstaReal® Astaxanthin together with naturally occurring algal lipids. This 10% astaxanthin oil is then spray dried in Japan by AstaReal’s parent company, Fuji Chemical Industries Ltd., Co. to provide a flowable powder for capsules, tablets, and more.

Why are the algae used to make AstaReal® astaxanthin grown indoors?

Conventional outdoor cultivation methods expose algae to variable weather and a higher risk of biological and chemical contamination. This can affect algal growth, astaxanthin production, and the final quality and stability of natural astaxanthin.

AstaReal has optimized Haematococcus pluvialis cultivation for more than 35 years since pioneering the natural astaxanthin industry. Today, AstaReal’s state-of-the-art closed indoor cultivation facilities in the USA and in Sweden nurtures algae using the best science and technology. This consistently provides optimal growth conditions for our algae, helps reduce contamination risk, and allows precisely timed harvests to maximize yield, stability, and quality.
