Spirulina is a blue-green algae supplement made from Arthrospira platensis. It is valued for its protein content and antioxidant compounds such as phycocyanin.

What are the potential benefits of spirulina?

Spirulina may support antioxidant and anti-inflammatory activity, help improve some blood lipid markers, and modulate certain immune functions. Effects can vary by person and health status.

How much spirulina should I take?

Common supplemental amounts are about 1–3 g per day. Follow the product label and consider medical advice if you have health conditions or take medications.

Is spirulina a reliable source of vitamin B12?

Spirulina contains B12 analogs that may not be biologically active in humans. People relying on B12 should use a proven B12 supplement or fortified foods.

Are there safety concerns with spirulina?

Quality matters because contamination can occur in poorly controlled products. People who are pregnant, immunocompromised, or have autoimmune conditions should consult a clinician before use.
