Product Overview

  • Dietary Supplement

For over 30 years spirulina (Arthrospira platensis) has been the premier choice for supplementing a vegetarian diet. Source Naturals Spirulina is a high quality blue green algae which is a high protein, low fat source of numerous vitamins, minerals, carotenoids and essential fatty acids. Spirulina is an excellent source of many nutrients that are hard to maintain at adequate levels with a vegetarian diet. Most notable is the high quality protein, which contains all nine essential amino acids. Spirulina's cell walls do not contain cellulose to slow digestion. Source Naturals Spirulina is naturally grown and harvested without herbicides or pesticides.

Suggested Use

Use 1 rounded tablespoon daily mixed in water or juice or add to soup, pasta, etc., after cooking.

Posted by Reviewer2624820 on Jan 23, 2009

Its actually coming from china and it isnt certified organic (which it should be when its coming from china) I recommand Nutrex Hawaian spirulina instead of this one!

Great Spirulina and good value

Posted by Reviewer2778088 on Apr 25, 2010

but I’m going to buy the organic version from the same company next time – even if it’s more expensive for the same amount it’s so much more concentrated that it becomes cheaper in use. And it has much more B-12.

Pure and fresh

Posted by 5008111116076351787 on Dec 11, 2014

This is by so far the best Spirulina powder I have bought at Iherb. It feels fres and pure, and smells like Spirulina should do, it also blends good in a shaker.

What my body had been waiting for!!!

Posted by Reviewer1534079 on Mar 11, 2010

Never tried Spirulina before, and was bracing myself for a horrible taste when I saw the thick green sludge when I mixed it with water (my wife won't touch it!!). But as soon as I put it in my mouth, I could have finished the whole bottle in one go. It was as if my body had been patiently waiting for this for years. Since starting to take it, I have felt a marked increase in energy. The serving size is generous as well (9 grams), which may account for the strength of the effect.
