Spirulina is one of the oldest life forms on Earth. In fact, this blue-green microalga is partly responsible for producing the oxygen in the planet’s atmosphere that, billions of years ago, allowed the planet’s original life forms to develop.
Spirulina is a spiral-shaped microalga. The only food proposed by NASA and the European Space Agency (ESA) to be the Astronauts’ food for long term space missions.
NASA declared that 1 gram of Spirulina has the equivalent nutrients of 1 kilogram of assorted balanced fruit and vegetables.
