Spirulina (Limnospira platensis) is a nutrient-dense microalga that contains beneficial polysaccharides with multiple health benefits. Researchers extracted and analyzed these polysaccharides, finding they have strong antioxidant properties and can help regulate blood sugar levels by inhibiting α-glucosidase enzymes. These compounds also support beneficial gut bacteria growth, making spirulina a promising natural ingredient for functional foods and health supplements.
