Spirulina (Arthrospira platensis) rests atop the green superfood pantheon. This blue-green vegetable plankton has been a source of nutrition for humans since the Aztecs harvested it centuries ago. Spirulina very well may have been the first photosynthetic life form created, and it still contains the rich nutrient content that supports the diversity of life we have on Earth today.
