Spirulina contains the most remarkable concentration of nutrients. It's the highest protein food- over 60 percent all digestible vegetable protein. It has the highest concentration of beta carotene, vitamin B-12, and contains potassium, calcium, magnesium, zinc, selenium, phosphorous and iron and the rare essential fatty acid GLA. These make spirulina a great whole food alternative compared to isolated vitamin and minerals. Fushi's certified organic Spirulina capsules contain pure Hawaiian Spirulina and nothing else. Fushi superfoods are bio-dynamically grown, cold processed and 100% raw to retain their complete nutritional properties. They are grown and derived from sustainable sources. We believe in being honest to our customers, kind to our planet and responsible for our actions. For the packaging of our Superfoods we have chosen to use glass, a recyclable material. We do not use the more popular laminated pouches as these are unrecyclable. We aim to use materials that are best for the planet, and reflect our ethos of being earth friendly. So they might not be as pretty, but they're kinder for the planet!
