Spirulina, a blue-green algae, has been explored for its potential benefits in supporting liver health, including in cases of hepatitis. The primary basis for its use is scientific investigation rather than long-standing traditional practice. Several animal studies and a handful of small human trials have suggested that spirulina possesses antioxidant, anti-inflammatory, and immunomodulatory properties, which may help mitigate liver damage and oxidative stress associated with hepatitis, particularly hepatitis C. For example, a few pilot studies have reported improvements in liver enzyme levels (such as ALT and AST) and overall well-being in patients with chronic hepatitis C after supplementation with spirulina. Spirulina's active compounds, including phycocyanin and various polysaccharides, are believed to help reduce liver inflammation and protect against cellular damage. However, the clinical evidence remains limited in both quality and quantity. Most studies to date have small sample sizes, short follow-up periods, and lack rigorous controls. There is insufficient data to conclude that spirulina can directly treat hepatitis or significantly alter the course of the disease. Major health organizations do not currently endorse spirulina as a standard therapy for hepatitis. In summary, while there is some preliminary scientific evidence suggesting that spirulina may provide supportive benefits for liver health in hepatitis, the strength of this evidence is weak to moderate at best (rating: 2/5). Further large-scale, well-designed clinical trials are needed to confirm its efficacy and safety for this indication.
