Spirulina health benefits?

Spirulina is a form of blue-green algae (cyanobacteria) which is cultivated around the globe. It can be used as both a dietary supplement and as a whole food in and of itself. Spirulina needs a PH of 8.5 and above to flourish, and a temperature of around 30 degrees Celsius.

Spirulina can make its own food and is quite easy to cultivate. It can be grown with a combination of sea salt, iron sulphate, baking soda, potassium nitrate and potassium phosphate. And, of course, a water solution. All these compounds are easily found in any aquarium, with the possible exception of iron sulphate.


Spirulina is mostly found in freshwater lakes, ponds, and rivers. Spirulina has existed on the planet for thousands of years and uses the sun as a source of energy.

Spirulina was a food source for both the Aztecs and the Mesoamericans until the 16th century. It is the food of astronauts for long-term space missions, endorsed by both NASA and the European Space Agency. The nutritional profile of spirulina is outstanding. There are almost 1200 peer reviewed studies on the different benefits of spirulina.

Spirulina has been declared by the United Nations to be the food of the future. Spirulina is the very same algae that can be seen on the top of lakes, though it is recommended that you buy a recognized brand that is guaranteed to be free from pollution.

Spirulina is much like the sea vegetables kelp and chlorella, and a little higher than marine phytoplankton on the food chain. Spirulina is not true algae in biological terms, as it is not organized in a membrane-bound nucleus like other algae.
