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 of the highest quality available. This special blue-green algae is a good source of numerous vitamins, minerals, carotenoids, and essential fatty acids 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 down digestion. Source Naturals Spirulina is naturally grown and harvested without herbicides or pesticides.

Suggested Use

6 tablets daily with meals.

Other Ingredients

Modified cellulose gum, colloidal silicon dioxide, and stearic acid.

Not Just For Health Nuts

Posted by Reviewer2060826 on Jan 24, 2007

Four years ago, I started using spirulina while receiving chemotherapy. I had no appetite and was concerned about getting ample nutrition. I found that I was able to digest this blue-green algae, when I couldn't tolerate other foods. I'm cancer-free now, and Source Naturals Spirulina is still part of my daily diet, because I seldom manage to eat the amount of green veggies recommended by the American Cancer Society. I don't consider myself a health nut -- just serious about my health. I'm also budget-minded, and found iherb's prices to be very competitive.

Great Company

Posted by Reviewer3080355 on Jun 28, 2011

I called head office to find out where they were getting their product from because I didn't want Japanese obviously but I also didn't want Hawaiin because of radiation. Turns out they're getting it from China so I bought lots and me and my children are very happy with it.
