Spirulina is emerging as a highly valuable adjunctive supplement for gastroenterologists in India, offering multi-dimensional benefits for gut, liver, and systemic digestive health. As a natural prebiotic, Spirulina promotes the proliferation of beneficial gut microbiota—particularly Lactobacillus and Bifidobacterium species—which contributes to enhanced gut barrier integrity, reduced intestinal inflammation, and improved nutrient assimilation (Chamorro-Cevallos et al., 2014; Selmi et al., 2011). It is especially beneficial in patients suffering from Irritable Bowel Syndrome (IBS), as its anti-inflammatory, antioxidative, and immunomodulatory properties help alleviate bloating, abdominal discomfort, and irregular bowel movements without causing gastrointestinal irritation. Its high digestibility and >95% nutrient absorption rate make it suitable for patients with compromised digestive capacity, including those with malabsorption syndromes or post-antibiotic gut dysbiosis (Karkos et al., 2011).
Additionally, Spirulina exhibits proven hepatoprotective effects, aiding in detoxification by neutralizing free radicals and enhancing the activity of glutathione and catalase enzymes, thereby reducing hepatic steatosis and inflammation in patients with non-alcoholic fatty liver disease (NAFLD) or drug-induced liver injury (Babadzhanov et al., 2004; Rafat et al., 2020). Its low-fat, low-residue, nutrient-rich composition provides therapeutic nourishment with minimal metabolic burden, especially important in gastrointestinal patients with altered digestion and absorption. Given its systemic compatibility, high safety profile, and biochemical synergy with gut and liver physiology, Spirulina is an ideal functional supplement in gastroenterological practice in India.
