Educational only, not medical advice. OncoForge makes no claim that Spirulina + Chlorella treats, prevents, or cures any condition, beyond what the linked studies show. Evidence levels vary; effects may not translate to people, and some compounds can cause harm. Always coordinate with your oncology team.

Key Takeaway

Microalgae pairing with anti-inflammatory phycocyanin (COX-2/iNOS downshift), immune-stimulating polysaccharides (IL-2/IFN-γ; NK/CTL activity), and GI binding of select metals/toxins; small human studies suggest QoL/immune benefits and pollutant/metal lowering. Use third-party–tested products to avoid microcystin/metal contamination.

Evidence at a glance

Tier 2 · animalCholangiocarcinomaColorectalBreastLung

Preclinical COX/immune robust; phase II cholangioma NK ↑; meta-QoL modest; detox fecal signals; ongoing CRC/breast trials; quality variability noted.

How it may work

Spirulina phycocyanin inhibits COX-2/NF-κB and reduces prostaglandins; sulfated polysaccharides enhance APC activation and Th1 cytokines, increasing NK/CTL cytotoxicity. Chlorella cell wall components and fiber bind certain metals (e.g., Cd, Pb) and dioxin-like compounds in the gut, supporting fecal elimination. Both modulate gut microbiota and short-chain fatty acids, indirectly improving mucosal immunity and treatment tolerance.
