Rating (out of 5): 2

Spirulina, a blue-green algae, has been traditionally used as a nutrient-rich food source but also has some scientific evidence supporting its use during convalescence—the period of recovery after illness or surgery. Spirulina is rich in protein, vitamins (such as B12), minerals (like iron), and antioxidants, making it attractive for supporting nutritional needs during recovery. Several small clinical studies and animal experiments have explored spirulina’s role in enhancing immune function, reducing inflammation, and improving overall vitality, which are important factors in convalescence.

For example, some studies have shown that spirulina supplementation can increase immune markers such as interferon-gamma and natural killer cell activity. Additionally, spirulina has demonstrated antioxidant and anti-inflammatory properties, which could theoretically help mitigate oxidative stress and inflammation often experienced during recovery. Its high protein content is beneficial in cases where patients struggle to maintain adequate nutrition, especially if appetite is low.

However, the direct scientific evidence for spirulina specifically accelerating or improving outcomes during convalescence in humans is limited. Most studies are small, preliminary, or conducted in animals. While the nutrient density of spirulina supports its use as a supplement in convalescence, robust clinical trials are lacking. Therefore, while there is a scientific rationale and some preliminary evidence, the overall scientific support is modest.
