Introduction

Spirulina is a type of cyanobacterium, often referred to as blue-green algae, that thrives in alkaline water bodies and has been consumed as a functional food for centuries. It has gained recognition as a nutraceutical food supplement globally due to its impressive nutritional profile and potential health benefits. Recent research highlights its therapeutic effects on various health conditions such as hypercholesterolemia, cardiovascular diseases, inflammatory diseases, cancer, and viral infections. This review focuses on the pharmacognostic aspects and significant health benefits associated with spirulina.

Nutritional Profile of Spirulina

Spirulina is renowned for its exceptional nutritional qualities, comprising nearly 71% protein, making it one of the highest natural protein sources available. Compared to traditional protein sources, spirulina offers five times the protein content of meat and three times that of soybean. Additionally, spirulina is rich in essential amino acids, carotenoids, vitamins (such as B complex and vitamin E), minerals (notably iron, calcium, and magnesium), and essential fatty acids. Its nutrient density has earned it the title of a superfood, making it an attractive dietary supplement for individuals of all ages and lifestyles.

Potential Health Benefits: Cardiovascular Health

One of the most significant health benefits of spirulina is its cardioprotective effects. Studies suggest that spirulina may help lower cholesterol levels, specifically reducing low-density lipoprotein (LDL) cholesterol while raising high-density lipoprotein (HDL) cholesterol. Research has demonstrated that daily consumption can lead to reductions in blood cholesterol and triglycerides, improving overall cardiovascular health markers. Furthermore, some clinical trials indicate that spirulina consumption can also reduce hypertension, presenting it as a viable functional food for cardiovascular wellness.

Antioxidant and Anticancer Properties

Spirulina has exhibited notable antioxidant and immune-modulating characteristics, which may contribute to its potential anticancer effects. While most evidence comes from animal and in vitro studies, some human trials have shown that spirulina might have a role in preventing cancer progression, particularly oral cancers. Notably, a study indicated a significant rate of regression in leukoplakia, a precursor to oral cancer, after participants consumed spirulina supplements for one year. These findings, though preliminary, provide a rationale for further investigation into spirulina’s cancer-preventive properties.

Conclusion

Spirulina stands out as a highly nutritious food with a multitude of health benefits, supporting its status as a superfood. Its rich nutrient profile, combined with potential cardiovascular benefits and promising anticancer properties, underscores its value as a dietary supplement. Continued research is necessary to establish definitive health claims, but current findings highlight spirulina’s role in enhancing nutritional intake and promoting overall health. This review confirms the potential of spirulina as an essential component of health-conscious diets, worthy of further scientific exploration.
