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 originating life forms to develop. Spirulina is the world's first super food, and one of the most nutrient-rich foods on Earth. Spirulina has between 55 and 70% protein (more than beef, chicken, and soybeans), 8 essential and 10 non-essential amino acids, as well as high levels of gamma-linolenic acid (GLA), beta-carotene, linoleic acid, arachidonic acid, vitamin B12, iron, calcium, phosphorus, nucleic acids RNA & DNA, chlorophyll, and phycocyanin, a pigment-protein complex that is found only in blue-green algae.  

Spirulina is a microorganism popularly known for its natural ability of providing nutrients and reducing weight. It does not work by burning fat directly but works in other ways such as giving the body the necessary nutritional requirements. It is a unique natural source considering its various health benefits. It does not matter the need, Spirulina is just beneficial from its nutrients and vitamins. It assures better health for its consumers. 

Spirulina is low in calories as it provides only 3.9 calories for every gram of its protein. Beef on the other hand, provides 65 calories for every gram of its protein. A standard 500 milligram tablet of Spirulina contains only 2 calories. When consumed regularly, it provides the body with the daily nutritional needs without excess calories. It increases the nutrient concentration within the body hence reduces cravings for food and hunger.
