Why should I take... SPIRULINA

This blue-green algae, which grows naturally in lakes, is available in tablet form, flakes or as a powder, and it’s known to contain essential amino acids, B vitamins, iron and the nutrients calcium, niacin and potassium. Tests on animals and in the lab indicate that spirulina may improve the immune system, but these studies have yet to be replicated in any large scale on humans. Claims that it can help with everything from ADHD to weight loss are unproven.
