Earthrise Spirulina – Straight from Sunny California

Earthrise Spirulina

The Proteus Corporation (later Earthrise), was established in 1976 by a group of American investors with an ambitious and noble objective to develop spirulina as a global food source.

In 1981, Earthrise to further their ambition, partnered with Japanese company (Dainippon Ink and Chemicals, Inc.) who were also developing microscopic green algae as a food source, and for use in biochemicals and pharmaceuticals. 

Today Earthrise (now wholly owned by the Japanese DIC Corporation) is one of the biggest manufacturers of spirulina in the world, and still holds true to the initial ideal of developing spirulina as a world food resource – by donating spirulina for humanitarian causes in the US and around the globe, as well as sponsoring the development of spirulina farms in developing countries!

On the Farm:

The Earthrise spirulina farm is located in the Sonoran Desert, southeastern California a location of the earth far removed from modern day pollutants. The farm grows spirulina in a controlled environment, free of pesticides and herbicides in ponds filled with water channeled from the nearby Colorado River.
Earthrise, go to great lengths to ensure the spirulina they produce is nutritionally potent and pure –

Weed Algae Removed:

To make a pure form of spirulina it is vital that unwanted algae and other microorganisms are removed from the feeding ponds, it is these same unwanted algae and microorganisms that can cause spirulina to be contaminated and thus unsafe for human consumption

To ensure that spirulina contains no unwanted algae or microorganisms, Earthrise use a specialized pond system with different filtering stages, high alkaline waters, food grade liners, and a balanced ecology. 

Long Paddles used for Optimum Growth:

The ponds used to make spirulina cannot be static they must be occasionally mixed to prevent top layer from burning and bleaching as this reducing the nutritional value of the end harvest. Earthrise mix their ponds using 50 foot paddles which ensures that the algae does not burn and bleach, this mixing also ensure the fresh water and nutrients that are added daily get evenly distributed throughout the feed. 
High quality CO2:

Algae need carbon to thrive but they grow at such a rate that atmospheric C02 is not enough to sustain optimum growth. To get around this problem, Earthrise pump high quality CO2, the same as you would find in bottles of carbonated water bought in your local store or supermarket, directly into the ponds.
Pure minerals and nutrients used:

Spirulina is an acquired taste to say the least, and in some cases the taste is just downright horrible, this is especially true when manure or other such organic matter are the main sources of nutrient feed used in the growing ponds.
Earthrise use only pure, non-smelly, quality minerals and nutrients such as nitrogen, potassium, iron and essential trace elements to feed their spirulina. 

Quick Drying Process:

Earthrise, use a quick heat drying process to preserve heat sensitive nutritional properties. This process involves spirulina droplets been sprayed into a drying chamber where they are briefly exposed to heat which evaporates the moisture without losing the heat sensitive nutrients, enzymes and pigments.


Spirulina when not stored correctly will lose nutritionally potency, Earthrise store their final product in specialized oxygen barrier containers, which preserve the near full nutritional value of the spirulina powder for up to four years or 


Contaminated spirulina products can cause unwanted and sometimes even severe side effects, so it is very important that you buy pure spirulina from a trusted manufacturer, and Earthrise, are definitely in a league of their own, well actually their not, Nutrex would have to be in that league too when it comes to spirulina food safety manufacturing practices.

Technicians to ensure the ecology is balanced, and that no unwanted organisms or algae are present test growing ponds daily. The final powder product is tested too before been approved for shipping, all and all over 40 different tests are conducted to ensure the safety and purity of the spirulina. 

As far a safety and manufacturing accolades go, Earthrise hold GMP, ISO 9001, and FSSC certificates these are three heavy weight endorsements that attest to manufacturing, production, and food safety process employed by Earthrise. 

Earthrise, also boast they are the only company in continental USA to produce spirulina with GRAS (Generally Recognized as Safe) status, however, this is a little cheeky, as NUTREX also have a GRAS status – it's just that their spirulina farm is in Hawaii. 

Nutrition & Health: 

All Spirulina will provide roughly the same nutritional properties and thus the same health benefits (read my earlier post on Spirulina) but the concentration of these nutritional properties, and the purity of spirulina can differ, depending on the manufacturing and production processes used. Therefore, it stands to reason the better the product the more nutritional health benefit it will provide, and as we already know Earthrise provide one of the most nutritional and pure forms of spirulina on the market.   

Earthrise spirulina is rich source of protein (about 60% vegetable protein) phytonutrients, antioxidants and essential vitamins such as A, B1, B2, B3. It is also rich in minerals Calcium, Chromium, Copper, Iron, Magnesium, Phosphorus, Selenium, Sodium and Zinc; it is also a rich source of the essential fatty acid GLA (Gamma Linoleic Acid)


Earthrise spirulina is one of the best on the market, only comparable to Nutrex Hawaii – and anyone that knows spirulina will attest that both either brand is a winner. When you purchase Earthrise you can rest assured you are buying a quality product from an industry leader with over 35 years'experience growing spirulina.

  2. Howdy! This post could not be written much better!
    Looking at this article reminds me of my previous roommate!
    He always kept preaching about this. I’ll send this information to him. Fairly certain he’ll have a very good read.
    Thanks for sharing!
