Cyanobacteria, commonly referred to as blue-green algae, represent some of the earliest life forms to emerge on our planet. Specifically, spirulina thrives naturally in warm, alkaline aquatic environments. The use of microalgae as both human and animal sustenance has deep historical roots, dating back centuries. These organisms are highly versatile, offering a variety of food and industrial applications, and are favoured for their ability to withstand harsh environments regardless of the season. Spirulina, in particular, is highly prized for its exceptional nutritional profile and safety record, making it a viable dietary supplement. Given its dense concentration of essential nutrients and bioactive compounds, along with its lack of toxicity, spirulina serves as a potent tool to combat global malnutrition and address various dietary deficiencies in the future.
