From all my research, I believe there are a few spirulina brands that consistently rise to the top as the best. Here are my top three.
Earthwise Spirulina Natural Powder is a very high-quality spirulina produced in California. Earthwise has the world’s largest spirulina farm in the Sonoran Desert of southeastern California far from highways, airports and cities. Their Spirulina is grown under a controlled environment without the use of pesticides and herbicides, and with an effort to be environmentally friendly. This trusted brand makes a delicious, healthy spirulina that we would highly recommend. Check out the rave reviews , and then try some for yourself!
Healthforce Spirulina Azteca is a wonderful spirulina made in Chile. HealthForce Nutritionals is a 20-plus year, 100% hard-core, vegan, therapeutic superfoods company. They’ve created a purist, hard-core quality standard for sourcing and production which they claim is significantly beyond Organic called Truganic. All of their products have to pass tests to adhere to these high standards. Spirulina Azteca is a certified organic variety from Chile in South America. It is grown in a man-made environment, and is certified contaminant free. It has a bit stronger taste and smell than their California product, but it mixes well.
Nutrex-Hawaii Hawaiian Spirulina Pacifica is one of the most popular brands of spirulina and for good reason. Nutrex-Hawaii makes a high-quality, delicious spriulina that I absolutely love. Situated on the bright, sunny Kona coast, Nutrex-Hawaii’s 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. Everyone raves about the wonderful taste of spirulina grown in Hawaii.
