Cyanotech Corp

Cyanotech Corp is a U.S.-based producer of microalgae-derived nutritional ingredients and finished supplements, built around Hawaiian Spirulina Pacifica and BioAstin Hawaiian Astaxanthin. The company grows, harvests, processes, and sells spirulina and astaxanthin in bulk form to ingredient customers and in packaged consumer form through its Nutrex Hawaii subsidiary. It also monetizes its extraction expertise through contract extraction services and, more recently, third-party R&D services. Cyanotech’s business is tied to its Kona, Hawaii production site, where climate, cultivation conditions, and production volume directly affect output, quality, and margins.
