Spirulina is a type of cyanobacteria commonly referred to as blue-green algae. It is valued for its high nutritional content, which includes a significant amount of protein, vitamins, minerals, and essential fatty acids¹².

The health benefits of Spirulina are extensive. It is well-known for its antioxidant, anti-inflammatory, and immunomodulating properties¹³. Research indicates that Spirulina can support cardiovascular health by reducing blood lipids, aiding in weight loss, and possibly improving blood pressure and glucose levels⁴.

Additionally, Spirulina is associated with beneficial effects on brain health. It has been demonstrated to possess neuroprotective mechanisms and may help in reducing mental fatigue and improving cognitive skills³⁵. In the realm of sports and physical performance, Spirulina has shown potential in enhancing aerobic capacity and strength, particularly in untrained or moderately trained individuals¹.

Overall, Spirulina is considered a "superfood" due to its rich nutrient content and the multitude of health benefits it appears to offer¹⁶.
