About Nutrex Hawaii 

About Nutrex Hawaii

Nutrex Hawaii was founded in Kailua-Kona, Hawaii in 1990 by Dr. Gerald Cysewski, a world-renowned expert in microalgae and carotenoids.  Our mission is to utilize the benefits of microalgae to improve health and extend lives in the world wide community.   Carved out of land that was once a barren lava flow, Nutrex Hawaii is located on the pristine Kona coast on the Big Island of Hawaii.  Our farm draws on the natural resources that surround us – abundant warm sunlight, pure deep ocean water and 100% fresh water drawn from Hawaiian aquifers to cultivate:  

Hawaiian Spirulina Pacifica® – a superior strain of Spirulina, with the highest known nutritional content of any Spirulina.  

BioAstin® Hawaiian Astaxanthin® – 100% pure, natural Hawaiian Astaxanthin™, the world’s strongest natural antioxidant with benefits for joint health, skin health, eye and brain health and for athletes and active people.  

What Makes Nutrex Hawaii Products Unique?


Situated on the bright, sunny Kona coast, our farm receives more sunlight than any other coastal location in the United States enabling Nutrex Hawaiian Spirulina Pacifica to grow continuously for 12 months a year.  Our ponds have been in operation since 1985.   What does that mean for you?  More nutrition.  Spirulina Pacifica has evolved into a nutritionally superior strain after more than 25 years of continuous cultivation in the intense Hawaiian sun.  

BioSecure Zone  

Nutrex Hawaii is the only microalgae farm located in a “BioSecure Zone” that prohibits the use of harmful pesticides and genetically modified organisms.   What does that mean for you?  Our Hawaiian Spirulina Pacifica and BioAstin Hawaiian Astaxanthin products are grown without using any harmful pesticides, herbicides and we do not generate land erosion or water pollution. Our products are safe and pure.

100% Potable Drinking Water  

Our products are grown with 100% potable drinking water.  This water is collected from the Big Island’s pristine aquifer.  After being natural filtered through lava rock, this water is as fresh as it gets.  To minimize water waste and return essential nutrients back into our growing ponds, the majority of the fresh water is recycled and returned to the pond for the next growing cycle.  This process contributes to providing the world’s most nutritious Spirulina.  

•Ultra-Pure Deep Ocean Water  

Five percent deep ocean water is added to the growing media for Hawaiian Spirulina Pacifica. Hawaiian Spirulina is the only cultured microalgae grown with ultra-pure deep ocean water pumped up from a depth of 2000 feet below sea level. This ocean water is adds trace minerals and elements to the Spirulina.

•Ocean Chill Drying™  

Nutrex Hawaii’s patented Ocean Chill Drying™ system eliminates oxidation and damage to carotenoids, enzymes and other fragile nutrients that occur in standard drying methods.   What does that mean for you?  Nutritional content that you can rely on.  This patented system dries our Spirulina in just 3-7 seconds, relies on very cold deep ocean water to provide de-humidification and uses less than one percent oxygen to preserve the phytonutrients.  And because of our superior packaging, our Spirulina arrives to the consumer as fresh as the day it was harvested.  

Envronmental Responsibility & Sustainability

Nutrex Hawaii’s corporate philosophy is to leave the land and environment in better condition than when we started. All of our microalgae comes from our parent company Cyanotech’s 90-acre farm located on the pristine Kona Coast on Hawaii Island. Our microalgae farm was carved out of land that was once a barren lava flow. Our team is steadfast in its commitment to sustainability and everything we do is to create a cleaner, safer and healthier world.
