Cyanotech Corporation CYAN

Company Overview

Cyanotech Corporation is a U.S.-based biotechnology and nutraceutical company specializing in the large-scale cultivation, production, and commercialization of microalgae-based products. The company operates primarily within the dietary supplements, functional foods, and natural ingredients industries, with a focus on algae-derived antioxidants and proteins. Its core products include astaxanthin and spirulina, which are sold as branded consumer supplements and as ingredients to other manufacturers.

The company’s primary revenue drivers are its flagship brands BioAstin® (astaxanthin) and Hawaiian Spirulina®, which are marketed for their antioxidant, anti-inflammatory, and nutritional properties. Cyanotech serves health-conscious consumers, dietary supplement brands, and food ingredient customers, with a unique positioning based on vertically integrated production and outdoor algae cultivation in Hawaii. Founded in 1983, the company evolved from a research-focused algae producer into a commercial manufacturer, and it became publicly traded in the 1990s, maintaining a niche but established presence in the global nutraceutical market.
