Spirulina is a clinically versatile, algae-derived nutraceutical that general physicians in India can confidently prescribe as an adjunct or supportive therapy for a wide range of health conditions, especially in nutritionally and immunologically stressed populations. With a dense concentration of high-quality protein (over 60%), bioavailable iron, β-carotene (provitamin A), B-complex vitamins, γ-linolenic acid (GLA), and potent antioxidants such as phycocyanin and superoxide dismutase (SOD), Spirulina provides holistic support across metabolic, infectious, inflammatory, and deficiency-related disease profiles (Khan et al., 2005; Mani et al., 2000).
It is particularly effective in post-antibiotic recovery, where gut microbiota disruption and nutrient depletion are common. Spirulina’s mild prebiotic action and micronutrient restoration help rebuild gastrointestinal integrity and energy metabolism, aiding faster recuperation without adverse effects (Selmi et al., 2011). In vector-borne illnesses such as dengue and malaria, which cause anemia and fatigue, Spirulina accelerates recovery through its hematopoietic action, enhancing erythropoiesis, reticulocyte response, and hemoglobin synthesis, without the hepatic overload often seen with synthetic iron preparations (Sankar et al., 2011; Kapoor & Mehta, 1993).
Additionally, Spirulina is a validated therapeutic food for chronic and acute malnutrition, especially in children and pregnant women, where it supports immune modulation, muscle growth, cognitive development, and micronutrient repletion (Mathew et al., 1995). Its safety, non-toxicity, and compatibility with standard treatments make it suitable for long-term use in managing type 2 diabetes, dyslipidemia, non-alcoholic fatty liver disease, respiratory ailments, chemotherapy recovery, and general fatigue syndromes (Parikh et al., 2001; Mazokopakis et al., 2014). In summary, Spirulina serves as a physician’s ally in preventive and restorative care, providing sustainable, multi-systemic health support with minimal contraindications.
