    What to know

    Spirulina is a blue-green algae that is about 60% protein by weight and contains iron and plant pigments. A few tablets supply only a gram or two, so it is a small top-up, not a protein source. It is not a reliable source of vitamin B12 for vegans, because much of its B12 is in a form the body cannot use. Chlorophyll supplements usually contain chlorophyllin, and claims about detox are not backed by good evidence.

    Who should check first

    • Phenylketonuria (PKU): do not take spirulina.
    • Autoimmune conditions or immune suppressing medicine: speak to your doctor first.
    • Blood thinners: spirulina contains vitamin K, so check with your doctor.
    • Pregnant or breastfeeding: check with your doctor first.
