Cyanotech Hawaiian Spirulina is the only cultured microalgae grown with ultra pure deep ocean water as a source of minerals and trace elements. The deep ocean water is pumped up from a depth of 2000 feet, supplying magnesium, calcium, and other trace elements.

Gentle stirring by paddle wheels assures perfect exposure to the intense Hawaiian sun. The growing medium employs a mixture of fresh water and mineral-rich deep ocean water in a base of food-grade baking soda. This managed growing system assures a contamination-free, consistently superior nutritional profile.

Cynotech meticulously washes the Hawaiian Spirulina over stainless steel screens. Using a pollution-free, 100% recycled process, they then return all the pond water to the growing ponds for the next growing cycle. Prior to drying, the Spirulina is vacuum washed three times with fresh water - giving it a mild, salt-free taste.

Ocean Chill Drying - a patented process - was developed to eliminate the oxidation of carotenes and fatty acids that occurs in standard dryers. The process employs a closed system which is kept at less than one percent oxygen by flushing with nitrogen and carbon dioxide.

The dried powder is immediately protected from oxidation. Using a process Cyanotech pioneered, oxygen absorbers are enclosed in heat-sealed, metal-lined drums.

This method of packaging assures that their customers receive Spirulina that is essentially as fresh as the day it was harvested.
