What makes DIC Spirulina unique

We only use spirulina species that are superior in safety, quality and efficacy.

There are many brands of spirulina, which have different nutritional values, safety, and quality. DIC Spirulina has been researched at universities, hospitals, and public institutions to confirm its high standards. Also, our Spirulina is certified ISO (international standard of the guarantee of quality), HACCP (general hygiene management production system), GMP (appropriate production model) and goes through a rigorous quality control system.

DIC/Earthrise® spirulina donated to children in need aroud the world.

"Spirulina is an interesting food, rich in iron, high in protein, and suitable for children" which WHO once commented to our Spirulina. "DIC Spirulina" was sent to children of Chernobyl and the children of the Croatian refugees who suffered from malnutrition.

Produced by an automated production line in our facility with rigorous in-line quality and safety measures in place.

DIC has been the pioneer in commercial spirulina production (since 1970) and one of the world's largest suppliers in t he world. For more than 40 years, we've maintained our high quality and honest practices.

What is high quality spirulina

“To grow high quality spirulina, it is crucial that you select the best algae that would best fit in the climate, and be attentive to the quality of water as well. In that respect, the area where Earthrise Nutritionals produces their spirulina is top quality. Colorado River, which is their main source of water for the farm, enables them to grow high quality spirulina with rich minerals from the river. In addition, they have been researching in this field for approximately 40 years. They have created an environment that is best for spirulina through their many years of research and data.”

Our production methods

Spirulina is a type of green algae that grows in specific conditions

Spirulina grows with strong sunlight under the special conditions such as high temperature and strong alkalinity which is almost inhabitable for many other animals and plants.This natural ability to thrive is the secret to Spirulina’s unique properties not found in other life forms. There are lakes that satisfy several of these conditions where Spirulina can be found growing in the wild.

About our farms

DIC Spirulina is farmed in manmade ponds using cultivation methods based on photosynthesis. We select our production locations with a temperate climate and relatively low annual rainfall.

Features of our farms

  • •We were first in the world to succeed in industrial mass-production of Spirulina in 1977
  • •We integrate all production processes end-to-end in our farms
  • •We select only algae strains that have superior safety and effectiveness

Assessments and credentials

DIC Spirulina quality control

Quality control of Spirulina is actually exceptionally difficult.
Because our aim is to deliver quality products that our customers can use with peace of mind, in our end-to-end integration production from cultivation through to the final product we regularly undergo safety testing performed by official organizations and collect a wealth of data. On top of this, we have DIC Group employees stationed on site who are accountable for production management, and we conduct quality testing of incoming goods based on stringent quality control standards even for transactions made inside the DIC Group.

Spirulina grown at our production facilities outside of Japan are made into finished products at facilities that are certified to ISO-9001, an international standard of quality assurance that sets forth quality control requirements from the receipt of raw materials to the outbound shipping of products.
