Spirulina is a blue-green microalga that’s been consumed for centuries, from Aztec civilizations to modern space explorations by NASA.
It’s incredibly nutritious, packed with protein (up to 70%), essential vitamins like B‑complex and beta‑carotenes, minerals (iron, magnesium), healthy fats (gamma‑linolenic acid), and antioxidants—all in a form that’s easy to digest.
Thanks to rigorous safety testing, the FDA considers it “Generally Recognized as Safe” (GRAS).
Spirulina platensis delivers an astonishing amount of protein—55–70% by dry weight—providing all essential amino acids, surpassing even soybeans in completeness. It also packs a rich blend of B‑complex, C, D and E vitamins, iron, calcium, magnesium, potassium, and trace minerals. Its healthy fats include valuable gamma‑linolenic acid, and its pigments like phycocyanin and phenolic compounds serve as powerful antioxidants.
Beyond nutrition, spirulina exhibits numerous bioactive effects—it has demonstrated antiviral, antibacterial, antioxidant, anti-diabetic, anticancer, and anti-inflammatory properties. These multifaceted health benefits elevate it beyond a mere supplement, bolstering its superfood status.
Cultivated in alkaline and saline waters, spirulina requires no fertile soil or freshwater, converting CO₂ into biomass while releasing oxygen. It thrives in barren environments, making it an eco‑friendly, sustainable food source.
