Potential side effects include: Gastrointestinal discomfort, Headache, Allergic reactions (rare), Contamination risk from wild-harvested sources (microcystins, heavy metals), May exacerbate autoimmune conditions (immunostimulatory).

What is spirulina and how does it support immune function?

Spirulina is a blue-green algae (cyanobacterium) rich in phycocyanin, a pigment with antioxidant and anti-inflammatory properties. Clinical studies have examined spirulina for its potential to enhance natural killer cell activity and modulate allergic immune responses.

What dosage of spirulina has been studied for immune support?

Clinical trials have used spirulina at doses of 1–8 g per day, with 2–4 g being the most common range for immune-related outcomes. For allergic rhinitis, doses of 1–2 g per day have been studied over periods of 4 to 12 weeks.

What are the potential side effects of spirulina?

Spirulina is generally well tolerated. Possible side effects include gastrointestinal discomfort, headache, and allergic reactions. Product quality is critical, as spirulina contaminated with microcystins or heavy metals poses health risks. Choose products tested for purity.

About

Spirulina's phycocyanin and polysaccharides enhance NK cell cytotoxicity and interferon-gamma (IFN-gamma) production, activate myeloid lineage cells, and exhibit potent antioxidant and anti-inflammatory activity. A 2020 comparative trial found spirulina was more effective than cetirizine for allergic rhinitis symptoms.

How It Works

Phycocyanin and polysaccharides enhance NK cell cytotoxicity and IFN-gamma production; activate myeloid lineage cells; phycocyanin also exhibits potent antioxidant and anti-inflammatory activity.
