Its exceptional protein content, coupled with prolific production, has helped combat malnutrition in many developing countries. Spirulina is highly digestible, at around 75 to 83%, because its cell wall is composed of murein (peptidoglycan), which is much more digestible than the typical pectocellulosic walls found in plants.

It is an extraordinary protein-producing machine, but that's not all! It is being touted as the miracle food of the 21st century. China, India, and the United States are leaders in this field, with industrial production accounting...
