Hawaiian Spirulina Pacifica™ is the only spirulina in the world that uses deep seawater containing many trace minerals during the growing process. Trace minerals are widely recognised for their nutritional benefits. The deep seawater comes from a pipeline that goes down 600 metres (2000 feet) below sea level. This exceptionally pure resource has been untouched by human activity. Scientists estimate that this water has not been in contact with surface waters for over 2000 years!
